OVERVIEW

Our Business

Huntington Ingalls Industries, Inc. ("HII", "we", "us", or "our") is America's
largest military shipbuilding company and a provider of professional services to
partners in government and industry. For more than a century, our Ingalls
segment in Mississippi and Newport News segment in Virginia have built more
ships in more ship classes than any other U.S. naval shipbuilder. Our Technical
Solutions segment provides a range of services to government and commercial
customers. Headquartered in Newport News, Virginia, HII employs approximately
42,000 people both domestically and internationally.
We conduct most of our business with the U.S. Government, primarily the DoD. As
prime contractor, principal subcontractor, team member, or partner, we
participate in many high-priority U.S. defense programs. Ingalls includes our
non-nuclear ship design, construction, repair, and maintenance businesses.
Newport News includes all of our nuclear ship design, construction, overhaul,
refueling, and repair and maintenance businesses. Our Technical Solutions
segment provides a wide range of professional services and products, including
defense and federal solutions ("DFS"), nuclear and environmental services, and
unmanned systems.
The following discussion should be read along with the unaudited condensed
consolidated financial statements included in this Quarterly Report on Form
10-Q, as well as our Annual Report on Form 10-K for the year ended December 31,
2020.

Business Environment

COVID-19 Pandemic - The COVID-19 global pandemic has had wide ranging effects on
the global health environment and disrupted the global and U.S. economies and
financial markets, including impacts to our employees, customers, suppliers, and
communities (collectively, "COVID-19 Events"). COVID-19 Events have also
                                       20
--------------------------------------------------------------------------------
  Table of Contents
impacted our operations, and the continuing impacts are uncertain. The most
significant elements of uncertainty have been the intensity and duration of the
impact on our employees' ability to work effectively, disruption in our supply
chain, disruption of the U.S. Government's and our other customers' abilities to
perform their obligations, and impact on pension assets and other investment
performance.

We are aggressively managing our response to the uncertainties regarding
COVID-19 Events. Our primary focus has been to minimize the risk to our
employees by updating leave policies, increasing telecommuting, and making
benefits changes to provide employees maximum flexibility. We have also adjusted
policies and workspaces to align with Centers for Disease Control and Prevention
("CDC") guidelines and to support social distancing, including increased
sanitation efforts, personal protective equipment for employees, and suspension
of all non-essential work travel. As a result, we have incurred and expect to
continue incurring costs related to COVID-19 Events, including paid leave,
quarantining employees, and recurring facility cleaning. Our shipyards and other
facilities remained open and productive, but we experienced temporary decreases
in workforce attendance, which impacted our operations due to delay and
disruption from the lack of availability of critical skills and out-of-sequence
work. As of March 31, 2021, our workforce was operating at normal attendance
rates.

Under Section 3610 of the CARES Act, contractors may submit claims for employee
paid time off caused by restrictions from COVID-19 Events in circumstances where
the employee could not work remotely. Such instances may include paid time off
for employees to allow for plant decontamination, idle time due to social
distancing restrictions, paid time off to take care of dependents impacted by
government ordered school or day care closures, and employee quarantines due to
travel restrictions or coming into contact, being diagnosed, or taking care of
someone diagnosed with COVID-19. We have taken steps to preserve our rights to
pursue such claims for HII and our subcontractors, but we have no assurance that
Congress will appropriate sufficient funds to cover the reimbursement of costs
contemplated by the CARES Act.

While costs related to COVID-19 Events are allowable under U.S. Government
contracts, our contract estimates reflect margin impact uncertainty, because
such costs may not result in equitable adjustments, particularly on firm fixed
price and fixed price incentive contracts, or may not be adequately covered by
insurance. Our reinsurers have failed to acknowledge coverage for various losses
related to COVID-19, and we filed a complaint in state court in Vermont seeking
a judgment declaring that our business interruption and other losses associated
with COVID-19 are covered by our property insurance program. We also initiated
arbitration proceedings against other reinsurers seeking similar relief.
Although we believe that our position is well-founded, no assurance can be
provided regarding the ultimate resolution of this matter. See Note 13:
Investigations, Claims, and Litigation.

We have also focused on actively supporting our customers, suppliers, and
communities. We have been proactive in engaging with our U.S. Government
customers regarding future contract adjustments. While there has been no change
in contract terms or substantial degradation in timely payments from customers,
we have experienced delays in decisions on certain contract awards. We are
unable to predict how our customers will allocate resources in the future as
they react to the evolving demands of the COVID-19 response. We have accelerated
payments to small business suppliers in an effort to minimize supply chain
disruption.

We temporarily halted stock repurchases in Q1 2020, but we resumed share
repurchases during the first quarter of 2021. We also deferred certain payroll
taxes pursuant to the CARES Act, which increased our cash from operations in
2020, but will reduce cash from operations in 2021 and 2022.

U.S. Government Contracts - Long-term uncertainty exists with respect to overall
levels of defense spending across the future years' defense plan, and it is
likely that U.S. Government discretionary spending levels will continue to be
subject to significant pressure.

The fiscal year 2021 budget cycle ultimately concluded with the passage and
enactment of defense authorization and defense appropriations measures. Both
pieces of legislation broadly supported shipbuilding programs, including funding
and authority for an additional Virginia class submarine, the bundled purchase
of LHA 9 (unnamed) with LPD 32 (unnamed) and LPD 33 (unnamed), and long-lead
material for an additional Arleigh Burke class (DDG 51) destroyer. The final
bills also continued support of the dual purchase of Enterprise (CVN 80) and
Doris Miller (CVN 81), as well as the Refueling and Complex Overhaul of USS John
C. Stennis (CVN 74).

Long-term funding for certain programs in which we participate may be reduced,
delayed, or canceled. In addition, spending cuts and/or reprioritization of
defense investment could adversely affect the viability of our suppliers,
subcontractors, and employee base. Our contracts or subcontracts under programs
in which we participate may be
                                       21
--------------------------------------------------------------------------------
  Table of Contents
terminated or adjusted by the U.S. Government or the prime contractor as a
result of lack of government funding or reductions or delays in government
funding. Significant reductions in the number of ships procured by the U.S. Navy
or significant delays in funding our ship programs would have a material effect
on our financial position, results of operations, or cash flows.

The budget environment remains a significant long-term risk. Considerable
uncertainty exists regarding how future budget and program decisions will
develop and what challenges budget changes will present for the defense
industry. We believe continued budget pressures will have serious implications
for defense discretionary spending, the defense industrial base, including HII,
and the customers, employees, suppliers, subcontractors, investors, and
communities that rely on companies in the defense industrial base. Although it
is difficult to determine specific impacts, we expect that over the longer term,
the budget environment may result in fewer contract awards and lower revenues,
profits, and cash flows from our U.S. Government contracts. It is likely budget
and program decisions made in this environment will have long-term impacts on
HII and the entire defense industry.

Critical Accounting Policies, Estimates, and Judgments



As discussed in our Annual Report on Form 10-K for the year ended December 31,
2020, we consider our policies relating to the following matters to be critical
accounting policies:

•Revenue recognition;

•Purchase accounting, goodwill, and intangible assets;

•Litigation, commitments, and contingencies;

•Retirement related benefit plans; and

•Workers' compensation.

As of March 31, 2021, there had been no material changes to the foregoing critical accounting policies, estimates, and judgments since December 31, 2020.



We have incorporated realized and estimated future effects of COVID-19 Events,
based upon current conditions and our judgment of the future impacts of COVID-19
Events, with respect to contract costs and revenue recognition, effective income
tax rates, and the fair values of our long-lived assets, financial instruments,
intangible assets, and goodwill recorded at our reporting units. See Note 2:
Basis of Presentation.

Contracts

We generate most of our revenues from long-term U.S. Government contracts for
design, production, and support activities. Government contracts typically
include the following cost elements: direct material, labor, and subcontracting
costs, and certain indirect costs, including allowable general and
administrative expenses. Unless otherwise specified in a contract, costs billed
to contracts with the U.S. Government are treated as allowable and allocable
costs under the Federal Acquisition Regulation ("FAR") and the U.S. Cost
Accounting Standards ("CAS") regulations. Examples of costs incurred by us that
are not allowable under the FAR and CAS regulations include certain legal costs,
lobbying costs, charitable donations, interest expense, and advertising costs.

We monitor our policies and procedures with respect to our contracts on a
regular basis to ensure consistent application under similar terms and
conditions, as well as compliance with all applicable government regulations. In
addition, the Defense Contract Audit Agency routinely audits the costs we incur
that are allocated to contracts with the U.S. Government.

Our contracts typically fall into one of four categories: firm fixed-price, fixed-price incentive, cost-type, and time and materials. See Note 7: Revenue.



•Firm Fixed-Price Contracts - A firm fixed-price contract is a contract in which
the specified scope of work is agreed to for a price that is predetermined by
bid or negotiation and not generally subject to adjustment regardless of costs
incurred by the contractor.

                                       22
--------------------------------------------------------------------------------
  Table of Contents
•Fixed-Price Incentive Contracts - Fixed-price incentive contracts provide for
reimbursement of the contractor's allowable costs, but are subject to a
cost-share limit that affects profitability. Fixed-price incentive contracts
effectively become firm fixed-price contracts once the cost-share limit is
reached.

•Cost-Type Contracts - Cost-type contracts provide for reimbursement of the
contractor's allowable costs plus a fee that represents profit. Cost-type
contracts generally require that the contractor use its reasonable efforts to
accomplish the scope of the work within some specified time and some stated
dollar limitation.

•Time and Materials - Time and materials contracts specify a fixed hourly billing rate for each direct labor hour expended and reimbursement for allowable material costs and expenses.



Contract Fees - Negotiated contract fee structures include: fixed fee amounts,
cost sharing arrangements to reward or penalize contractors for under or over
cost target performance, respectively, positive award fees, and negative penalty
arrangements. Profit margins may vary materially depending on the negotiated
contract fee arrangements, percentage-of-completion of the contract, the
achievement of performance objectives, and the stage of performance at which the
right to receive fees, particularly under incentive and award fee contracts, is
finally determined.

Award Fees - Certain contracts contain award fees based on performance criteria
such as cost, schedule, quality, and technical performance. Award fees are
determined and earned based on an evaluation by the customer of our performance
against such negotiated criteria. We consider award fees to be variable
consideration and generally include these fees in the transaction price using a
most likely amount approach. Award fees are limited to the extent of funding
allotted by the customer and available for performance and those amounts for
which a significant reversal of revenue is not probable.

Program Descriptions

For convenience, a brief description of certain programs discussed in this Quarterly Report on Form 10-Q is included in the "Glossary of Programs" in this section.

Operating Performance Assessment and Reporting



We manage and assess the performance of our business based on our performance on
individual contracts and programs using the financial measures referred to
below, with consideration given to the Critical Accounting Policies, Estimates,
and Judgments referred to in this section. Our portfolio of long-term contracts
is largely flexibly-priced. Therefore, sales tend to fluctuate in concert with
costs across our large portfolio of active contracts, with operating income
being a critical measure of operating performance. Under FAR rules that govern
our business with
                                       23
--------------------------------------------------------------------------------
  Table of Contents
the U.S. Government, most types of costs are allowable, and we do not focus on
individual cost groupings, such as cost of sales or general and administrative
expenses, as much as we do on total contract costs, which are a key factor in
determining contract operating income. As a result, in evaluating our operating
performance, we look primarily at changes in sales and service revenues, as well
as operating income, including the effects of significant changes in operating
income as a result of changes in contract estimates and the use of the
cumulative catch-up method of accounting in accordance with GAAP. This approach
is consistent with the long-term life cycle of our contracts, as management
assesses the bidding of each contract by focusing on net sales and operating
profit and monitors performance in a similar manner through contract completion.
Consequently, our discussion of business segment performance focuses on net
sales and operating profit, consistent with our approach for managing our
business.

Cost of sales for both product sales and service revenues consists of materials,
labor, and subcontracting costs, as well as an allocation of indirect costs for
overhead. We manage the type and amount of costs at the contract level, which is
the basis for estimating our total costs at completion of our contracts. Unusual
fluctuations in operating performance driven by changes in a specific cost
element across multiple contracts are described in our analysis.

Product sales for the three months ended March 31, 2021, increased $97 million,
or 6%, compared with the same period in 2020. Ingalls product sales increased
$26 million for the three months ended March 31, 2021, primarily as a result of
higher volumes in surface combatants and amphibious assault ships, partially
offset by lower volume in the Legend class NSC program. Newport News product
sales increased $55 million for the three months ended March 31, 2021, primarily
as a result of higher volumes in aircraft carriers. Technical Solutions product
sales increased $16 million for the three months ended March 31, 2021, primarily
as a result of the acquisition of Hydroid in March 2020 and higher volumes in
DFS.

Service revenues for the three months ended March 31, 2021, decreased $82
million, or 13%, compared with the same period in 2020. Ingalls service revenues
decreased $8 million for the three months ended March 31, 2021, primarily as a
result of lower volumes in surface combatant and amphibious assault ship
services. Newport News service revenues increased $11 million for the three
months ended March 31, 2021, primarily as a result of higher volumes in aircraft
carriers. Technical Solutions service revenues decreased $85 million for the
three months ended March 31, 2021, primarily as a result of the divestitures of
our oil and gas business and San Diego Shipyard, as well as lower volumes in DFS
services.

Cost of Product Sales

Cost of product sales for the three months ended March 31, 2021, increased $164
million, or 13%, compared with the same period in 2020. Ingalls cost of product
sales increased $1 million for the three months ended March 31, 2021, primarily
as a result of the higher volumes described above, partially offset by risk
retirement on Bougainville (LHA 8). Newport News cost of product sales increased
$64 million for the three months ended March 31, 2021, primarily as a result of
volume increases described above. Technical Solutions cost of product sales
increased $15 million for the three months ended March 31, 2021, primarily as a
result of the volume increases described above. Cost of product sales related to
the Operating FAS/CAS Adjustment increased $84 million for the three months
ended March 31, 2021, as described below.

Cost of product sales as a percentage of product sales increased from 79.4% for
the three months ended March 31, 2020, to 84.5% for the three months ended March
31, 2021. The increase was due to unfavorable change in the Operating FAS/CAS
Adjustment and lower risk retirement on the RCOH of USS George Washington (CVN
73), partially offset by higher risk retirement on Bougainville (LHA 8) and
Block IV of the Virginia class (SSN 774) submarine program and year-to-year
variances in contract mix.

Cost of Service Revenues



Cost of service revenues for the three months ended March 31, 2021, decreased
$68 million, or 12%, compared with the same period in 2020. Ingalls cost of
service revenues decreased $7 million for the three months ended March 31, 2021,
primarily as a result of lower volumes described above. Newport News cost of
service revenues increased $14 million for the three months ended March 31,
2021, primarily as a result of the volume increases described above. Technical
Solutions cost of service revenues decreased $94 million for the three months
ended March 31, 2021, primarily as a result of the lower volumes described above
and year-to-year variances in contract mix. Cost of service revenues related to
the Operating FAS/CAS Adjustment increased $19 million for the three months
ended March 31, 2021, as described below.

Cost of service revenues as a percentage of service revenues increased from
86.1% for the three months ended March 31, 2020, to 86.5% for the three months
ended March 31, 2021, primarily driven by an unfavorable change in the Operating
FAS/CAS Adjustment, partially offset by improved performance on DFS services and
year-to-year variances in contract mix.

Income (Loss) from Operating Investments, Net

The activities of our operating investments are closely aligned with the operations of the segments holding the investments. We therefore record income related to earnings from equity method investments in our operating income.


                                       25
--------------------------------------------------------------------------------
  Table of Contents
Income from operating investments, net for the three months ended March 31,
2021, increased $2 million from the same period in 2020, primarily due to higher
equity income from our nuclear and environmental joint ventures.

Other Income and Gains

For the three months ended March 31, 2021, we recognized a $3 million gain on the sale of our oil and gas business.

General and Administrative Expenses



In accordance with industry practice and the regulations that govern the cost
accounting requirements for government contracts, most general and
administrative expenses are considered allowable and allocable costs on
government contracts. These costs are allocated to contracts in progress on a
systematic basis, and contract performance factors include this cost component
as an element of cost.

General and administrative expenses for the three months ended March 31, 2021,
decreased $8 million from the same period in 2020, primarily driven by favorable
changes in current state income tax expense and lower overhead costs.

Operating Income

We consider operating income to be an important measure for evaluating our operating performance, and, consistent with industry practice, we define operating income as revenues less the related cost of producing the revenues and general and administrative expenses.



We internally manage our operations by reference to "segment operating income,"
which is defined as operating income before the Operating FAS/CAS Adjustment and
non-current state income taxes, neither of which affects segment performance.
Segment operating income is not a recognized measure under GAAP.  When analyzing
our operating performance, investors should use segment operating income in
addition to, and not as an alternative for, operating income or any other
performance measure presented in accordance with GAAP. It is a measure we use to
evaluate our core operating performance.  We believe segment operating income
reflects an additional way of viewing aspects of our operations that, when
viewed with our GAAP results, provides a more complete understanding of factors

and is a useful indicator to measure our performance. Because not all companies
use identical calculations, our presentation of segment operating income may not
be comparable to similarly titled measures of other companies.

Segment Operating Income

Segment operating income for the three months ended March 31, 2021, was $191
million, compared with segment operating income of $156 million for the same
period in 2020. The increase was primarily driven by higher risk retirement on
Bougainville (LHA 8) and on Block IV of the Virginia class (SSN 774) submarine
program, improved performance on DFS services and nuclear and environmental
services, partially offset by lower risk retirement on the RCOH of USS George
Washington (CVN 73).

Activity within each segment is discussed in Segment Operating Results below.

FAS/CAS Adjustment and Operating FAS/CAS Adjustment

The FAS/CAS Adjustment reflects the difference between expenses for pension and
other postretirement benefits determined in accordance with GAAP ("FAS") and the
expenses for these items included in segment operating income in accordance with
U.S. Cost Accounting Standards ("CAS"). The Operating FAS/CAS Adjustment
excludes the following components of net periodic benefit costs: interest cost,
expected return on plan assets, amortization of prior service cost (credit) and
actuarial loss (gain), and settlement and curtailment effects.

Effective January 1, 2021, we adopted the Safe Harbor methodology used in determining CAS pension costs. Under the new methodology, the interest rates used to calculate pension liabilities under CAS are consistent with those used in the determination of minimum funding requirements under the Employee Retirement Income Security Act of 1974 ("ERISA").

The components of the Operating FAS/CAS Adjustment were as follows:


                                                                       Three Months Ended
                                                                            March 31                           2021 over 2020

The Operating FAS/CAS Adjustment was a net expense of $40 million and a net
benefit of $63 million for the three months ended March 31, 2021 and 2020,
respectively. The unfavorable change in the Operating FAS/CAS Adjustment from
2020 to 2021 was primarily driven by the more immediate recognition of higher
interest rates under CAS.

Non-current State Income Taxes



Non-current state income taxes include deferred state income taxes, which
reflect the change in deferred state tax assets and liabilities, and the tax
expense or benefit associated with changes in state unrecognized tax benefits in
the relevant period. These amounts are recorded within operating income. Current
period state income tax expense is charged to contract costs and included in
cost of sales and service revenues in segment operating income.

Non-current state income tax expense was $4 million for each of the three months ended March 31, 2021 and 2020.

Interest Expense

Interest expense for the three months ended March 31, 2021, increased $5 million, compared with the same period in 2020, primarily due to interest on senior notes issued in 2020.

Non-Operating Retirement Benefit



The non-operating retirement benefit includes the following components of net
periodic benefit costs: interest cost, expected return on plan assets,
amortization of prior service cost (credit) and actuarial loss (gain), and
settlement and curtailment effects. For the three months ended March 31, 2021,
the favorable change in the non-operating retirement benefit of $16 million, was
primarily driven by higher 2020 returns on plan assets.

Other, Net

Other, net income increased $14 million for the three months ended March 31, 2021, compared with the same period in 2020, primarily driven by gains on investments in marketable securities and interest income.

Federal and Foreign Income Taxes

Our effective income tax rates on earnings from operations for the three months
ended March 31, 2021 and 2020, were 14.5% and 20.4%, respectively. The lower
effective tax rate for the three months ended March 31, 2021, was primarily
attributable to the tax loss associated with the sale of our oil and gas
business resulting in a reduction in the effective tax rate of 5.5%.

For the three months ended March 31, 2021, our effective tax rate differed from
the federal statutory tax rate primarily as a result of the tax loss associated
with the sale of our oil and gas business. For the three months ended March 31,
2020, our effective tax rate did not differ materially from the federal
statutory corporate income tax rate of 21%. See Note 11: Income Taxes.

KEY SEGMENT FINANCIAL MEASURES

Sales and Service Revenues



Period-to-period revenues reflect performance under new and ongoing contracts.
Changes in sales and service revenues are typically expressed in terms of
volume. Unless otherwise described, volume generally refers to increases (or
decreases) in reported revenues due to varying production activity levels,
delivery rates, or service levels on individual contracts. Volume changes will
typically carry a corresponding income change based on the margin rate for a
particular contract.

Segment Operating Income (Loss)



Segment operating income reflects the aggregate performance results of contracts
within a segment. Excluded from this measure are certain costs not directly
associated with contract performance, such as the Operating FAS/CAS Adjustment
and non-current state income taxes. Changes in segment operating income are
typically expressed in
                                       28
--------------------------------------------------------------------------------
  Table of Contents
terms of volume, as discussed above, or performance. Performance refers to
changes in contract margin rates. These changes typically relate to profit
recognition associated with revisions to estimated costs at completion ("EAC")
that reflect improved or deteriorated operating performance on that contract.
Operating income changes are accounted for on a cumulative to date basis at the
time an EAC change is recorded. Segment operating income may also be affected
by, among other things, contract performance, the effects of workforce
stoppages, the effects of natural disasters such as hurricanes, resolution of
disputed items with the customer, recovery of insurance proceeds, and other
discrete events. At the completion of a long-term contract, any originally
estimated costs not incurred or reserves not fully utilized, such as warranty
reserves, could also impact contract earnings. Where such items have occurred
and the effects are material, a separate description is provided.

Cumulative Adjustments

For the three months ended March 31, 2021 and 2020, favorable and unfavorable cumulative catch-up margin adjustments were as follows:

For the three months ended March 31, 2021, favorable cumulative catch-up
adjustments were related to risk retirement on Bougainville (LHA 8) and Block IV
of the Virginia class (SSN 774) submarine program. During the same period, none
of the unfavorable cumulative catch-up margin adjustments were individually
significant.

For the three months ended March 31, 2020, favorable cumulative catch-up
adjustments were related to risk retirement on the Virginia class (SSN 774)
submarine program, the RCOH of USS George Washington (CVN 73), the San Antonio
class (LPD 17) program, and other individually insignificant adjustments. During
the same period, none of the unfavorable cumulative catch-up adjustments were
individually significant.

Sales and Service Revenues

Ingalls revenues for the three months ended March 31, 2021, increased $20
million, or 3%, from the same period in 2020, primarily driven by higher
revenues in surface combatants, partially offset by lower revenues in the Legend
class NSC program. Surface combatant revenues increased due to higher volumes on
George M. Neal (DDG 131), Jeremiah Denton (DDG 129), and Jack H. Lucas (DDG
125), partially offset by lower volumes on USS Fitzgerald (DDG 62) restoration
and modernization following its redelivery and Delbert D. Black (DDG 119)
following its delivery. Revenues on the Legend class NSC program decreased due
to lower volumes on Stone (NSC 9) following its delivery. Amphibious assault
ship revenues were flat as a result of higher volumes on Pittsburgh (LPD 31),
Bougainville (LHA 8), and LHA 9 (unnamed), partially offset by lower volumes on
Richard M. McCool Jr. (LPD 29), Fort Lauderdale (LPD 28), and USS Tripoli (LHA
7).

Sales and Service Revenues

Newport News revenues for the three months ended March 31, 2021, increased $66
million, or 5%, from the same period in 2020, primarily driven by higher
revenues in aircraft carriers, naval nuclear support services, and submarines.
Aircraft carrier revenues increased primarily as a result of higher volumes on
Enterprise (CVN 80), the RCOH of USS John C. Stennis (CVN 74), and Doris Miller
(CVN 81), partially offset by lower volumes on Kennedy (CVN 79) and the RCOH of
USS George Washington (CVN 73). Naval nuclear support services revenues
increased primarily as a result of higher volumes in carrier and submarine fleet
support services, offset by lower volume in facility maintenance services.
Submarine revenues increased primarily as a result of higher volumes on the
Columbia class submarine program and the Virginia class (SSN 774) submarine
program. The higher volume on the Virginia class (SSN 774) submarine program was
due to higher volumes on Block V boats, offset by lower volumes on Block IV
boats.

Segment Operating Income

Newport News segment operating income for the three months ended March 31, 2021,
was $93 million, compared with segment operating income of $95 million for the
same period in 2020. The decrease was primarily due to lower risk retirement on
the RCOH of USS George Washington (CVN 73), partially offset by higher risk
retirement on Block IV of the Virginia class (SSN 774) submarine program.

Sales and Service Revenues



Technical Solutions revenues for the three months ended March 31, 2021,
decreased $58 million, or 18%, from the same period in 2020, primarily due to
the divestitures of our oil and gas business and San Diego Shipyard, as well as
lower volumes in DFS services, partially offset by the acquisition of Hydroid in
March 2020.

Segment Operating Income (Loss)

Technical Solutions segment operating income for the three months ended March
31, 2021, was $7 million, compared with a loss of $7 million for the same period
in 2020. The increase was primarily driven by improved performance on DFS
services and nuclear and environmental services, as well as a gain on the sale
of our oil and gas business.
BACKLOG

Total backlog as of March 31, 2021, and December 31, 2020, was approximately
$48.8 billion and $46.0 billion, respectively. Total backlog includes both
funded backlog (firm orders for which funding is contractually obligated by the
customer) and unfunded backlog (firm orders for which funding is not currently
contractually obligated by the customer). Backlog excludes unexercised contract
options and unfunded IDIQ orders. For contracts having no stated contract
values, backlog includes only the amounts committed by the customer.

Approximately 16% of the $46.0 billion total backlog as of December 31, 2020, is
expected to be converted into sales in 2021. U.S. Government orders comprised
substantially all of the backlog as of March 31, 2021, and December 31, 2020.

Awards



The value of new contract awards during the three months ended March 31, 2021,
was approximately $5.3 billion, comprised primarily of awards for the RCOH of
the USS John C. Stennis (CVN 74), construction of a 10th boat of the Virginia
class (SSN 774) submarine program, and construction of John F. Lehman (DDG 137).

LIQUIDITY AND CAPITAL RESOURCES



We seek to efficiently convert operating results into cash for deployment in
operating our businesses, implementing our business strategy, and maximizing
stockholder value. We use various financial measures to assist in capital
deployment decision making, including net cash provided by operating activities
and free cash flow. We believe these measures are useful to investors in
assessing our financial performance.

Cash Flows

We discuss below our major operating, investing, and financing activities for
the three months ended March 31, 2021 and 2020, as classified on our unaudited
condensed consolidated statements of cash flows.

Operating Activities



Cash provided by operating activities for the three months ended March 31, 2021,
was $43 million, compared with $68 million provided by operating activities for
the same period in 2020. The unfavorable change in operating cash flow was
primarily due to higher contributions to retiree benefit plans, partially offset
by a federal income tax refund and changes in trade working capital. The change
in trade working capital was primarily driven by the timing of receipts of
accounts receivable and payments of accounts payable.

For the three months ended March 31, 2021, we made discretionary contributions
to our qualified defined benefit pension plans totaling $60 million, compared
with $20 million of discretionary contributions for the same period in 2020. As
of March 31, 2021, we anticipate no further significant cash contributions to
our qualified defined benefit pension plans in 2021.

We expect cash generated from operations in combination with our current cash
and cash equivalents, as well as existing credit facilities, to be sufficient to
service debt and retiree benefit plans, meet contractual obligations, and
finance capital expenditures for at least the next 12 months.

Investing Activities



Cash used in investing activities for the three months ended March 31, 2021, was
$46 million, compared with $444 million used in investing activities for the
same period in 2020. The change in investing cash was driven by the acquisition
of Hydroid in 2020, disposition of our oil and gas business in 2021, and lower
capital expenditures in 2021, partially offset by the acquisition of a
non-controlling interest in Titan in 2021. For 2021, we expect our capital
expenditures for maintenance and sustainment to be approximately 1.0% of annual
revenues and our discretionary capital expenditures to be approximately 2.0 % to
3.0% of annual revenues.

Financing Activities

Cash used in financing activities for the three months ended March 31, 2021, was
$102 million, compared with $329 million provided by financing activities for
the same period in 2020. The change in financing cash was primarily due to a
decrease in net proceeds from revolving credit facility borrowings of $380
million, a decrease of net proceeds from issuances of commercial paper of $88
million, and a $4 million increase in cash dividend payments, partially offset
by a decrease of $35 million from common stock repurchases and a decrease of $6
million in employee taxes on certain share-based payment arrangements.

Free Cash Flow



Free cash flow represents cash provided by (used in) operating activities less
capital expenditures net of related grant proceeds. Free cash flow is not a
measure recognized under GAAP. Free cash flow has limitations as an analytical
tool and should not be considered in isolation from, or as a substitute for,
analysis of our results as reported under GAAP. We believe free cash flow is an
important liquidity measure for our investors because it provides them insight
into our current and period-to-period performance and our ability to generate
cash from continuing operations. We also use free cash flow as a key operating
metric in assessing the performance of our business and as a key performance
measure in evaluating management performance and determining incentive
compensation. Free cash flow may not be comparable to similarly titled measures
of other companies.

The following table reconciles net cash provided by operating activities to free
cash flow:
                                                                          Three Months Ended             2021 over

Free cash flow for the three months ended March 31, 2021, decreased $18 million
from the same period in 2020, primarily due to higher contributions to retiree
benefit plans, partially offset by a federal income tax refund, changes in trade
working capital, and lower capital expenditures.

Governmental Regulation and Supervision



The U.S. Government has the ability, pursuant to regulations relating to
contractor business systems, to decrease or withhold contract payments if it
determines significant deficiencies exist in one or more such systems. As of
March 31, 2021 and 2020, the cumulative amounts of payments withheld by the U.S.
Government under our contracts subject to these regulations were not material to
our liquidity or cash flows.

Off-Balance Sheet Arrangements



In the ordinary course of business, we use letters of credit issued by
commercial banks to support certain leases, insurance policies, and contractual
performance obligations, as well as surety bonds issued by insurance companies
principally to support our self-insured workers' compensation plans. As of March
31, 2021, $15 million in letters of credit were issued but undrawn and $272
million of surety bonds were outstanding. As of March 31, 2021, we had no other
significant off-balance sheet arrangements.

Lincoln (CVN 72) was 

redelivered to the U.S. Navy in


                                              the second quarter of 2017 and USS George Washington
                                              (CVN 73) arrived at Newport News for the start of its
                                              RCOH in August 2017.

Columbia class (SSBN 826) submarines Newport News is participating in designing the Columbia


                                              class submarine as a 

replacement for the current aging

Ohio class nuclear ballistic missile submarines, which
                                              were first introduced into service in 1981. The Ohio
                                              class SSBN includes 14 nuclear ballistic missile
                                              submarines and four nuclear cruise missile submarines.
                                              The Columbia class program plan of record is to
                                              construct 12 new ballistic missile submarines. The U.S.
                                              Navy has initiated the design process for the new class
                                              of submarines, and, in early 2017, the DOD signed the
                                              acquisition decision

memorandum approving the Columbia


                                              class program's Milestone B, which formally authorizes
                                              the program's entry into the engineering and
                                              manufacturing development phase. We perform design work
                                              as a subcontractor to Electric Boat, and we have
                                              entered into a teaming

agreement with Electric Boat to


                                              build modules for the entire Columbia class (SSBN 826)

                                              (SSN 774) experience. We have been awarded contracts
                                              from Electric Boat to begin integrated product and
                                              process development and

provide long-lead-time material
