Defense Budget for FY2003:
Data Summary
Summary
This report is designed to be a readily accessible source of facts and figures on
the FY2003 defense budget. Part I presents basic data on the national defense budget
request, including figures on budget authority and outlays for the Department of
Defense and for the national defense budget function. Part II shows trends in overall
defense spending, including figures on the growth and decline of defense spending,
on defense outlays as a share of federal expenditures, on defense outlays as a share
of gross domestic product, and on foreign military spending. Part III defines key
defense budget terms.
To illustrate trends in the regular defense program, most of the data included in
this report exclude costs of Operation Desert Shield/Desert Storm, which was largely
financed by allied contributions.

Defense Budget for FY2003:
Data Summary
Introduction
This report is designed to be a readily accessible source of facts and figures on
the FY2003 defense budget. Part I provides basic data on the Administration’s
FY2003 national defense budget request, submitted on February 4, 2002. It includes
data on budget authority and outlays for the Department of Defense (DOD) and for
the national defense budget function (Function 050). Part II shows trends in overall
defense spending, in personnel levels, and in military force structure. It includes data
showing the growth and decline of defense spending over time, defense outlays as a
share of total federal expenditures, and defense outlays as a share of gross domestic
product. It also includes a table showing military spending by foreign nations. Part
III defines key defense budget terms.
Data showing long term spending trends can be interpreted in different ways.
For example, while defense outlays are at historically low levels as a percentage of
total federal outlays, this trend is more a reflection of increases in federal entitlement
programs – notably the escalating costs of Medicare and Social Security – than
decreases in defense spending. Also, while defense outlays as a percentage of GDP
are at their lowest levels since World War II, in constant dollar terms they remain
comparable to average peacetime defense outlays during the Cold War.
Most of the data used in this report are taken from annual budget documents
prepared by the Office of Management and Budget (OMB). These data have several
features that users of this report should be aware of.
! First, figures represent the Administration’s request to Congress, including
requested changes in standing legislation, such as this year’s request for
changes in accounting for retirement benefits;
! Second, OMB sometimes adjusts figures for prior year budgets for purposes
of comparison with proposed budgets; and
! Third, the data show estimates of funding in years prior to the budget year
(FY2003) according to OMB conventions for “scoring” of funding, which may
differ from those used by the Congressional Budget Office or the Department
of Defense.

---

CRS-2
This year, all of these features of the OMB data have some quite significant
effects on estimated and projected funding for defense and other parts of the budget.
Major adjustments include:
(1) Financing of benefits for military and civilian personnel on an accrual
basis: Most federal retirement benefits, including benefits for uniformed military
personnel and DOD civilian personnel, have long been funded on the basis of “accrual
accounting,” in which the cost of future benefits for current employees is charged to
the employing agency as the benefits are accrued. Under accrual accounting
procedures, federal agencies pay the actuarily determined cost of future benefits into
a trust fund. Payments to retirees are then charged to the fund, not to the agency.
In the FY2003 and FY2004 defense budgets, three substantial adjustments involving
accrual accounting have a large effect on reported budget totals. These are:
! Accrual accounting for over-65 health care benefits for uniformed
personnel: The FY2001 Defense Authorization Act included a provision,
known as “Tricare-for-Life,” that guarantees DOD-provided health care to
over-65 military retirees and their dependents. Beginning in FY2003, these
benefits are being funded on an accrual basis. This results in (1) an increase of
$8.1 billion in FY2003 in the military personnel accounts to reflect the accrual
cost of future benefits for current uniformed personnel and (2) a reduction of
$5.6 billion in operation and maintenance accounts to reflect a payment from
the health care trust fund to DOD for providing care to over-65 retirees.
! Accrual accounting for all civilian personnel retirement pension and
health benefits: While most federal civilian retirement benefits are funded on
an accrual basis, a small part is not. Now the Administration is proposing to
fund all retirement benefits on an accrual basis. In FY2003, the proposed
change results in an increase of $3.3 billion (both in budget authority and in
outlays) in the Department of Defense budget.
! Accrual accounting for under-65 health care benefits for uniformed
personnel: Beginning in FY2004, the Administration is also proposing to
finance health care benefits for under-65 military retirees on an accrual basis,
in which, again, DOD would pay into a trust fund the cost of future benefits
for current employees and would receive reimbursement from the fund for
costs of under-65 retiree health care that it provides. Both the contributions
to the fund and reimbursements from the fund are reflected in budget
projections from FY2004 on.
(2) Adjustment of prior year budget figures for accrual accounting: OMB
has adjusted FY2001 and FY2002 figures – though not figures for earlier years – to
be comparable to the new, proposed treatment of civilian retirement and health
benefits. Thus, OMB figures include $3.0 billion in FY2001 and $3.2 billion in
FY2002 Department of Defense budget totals (both in budget authority and in
outlays) for increased civilian retirement accrual even though this accounting
procedure was not in place in those years.
(3) Fiscal year scoring of funding provided by the Emergency Terrorism
Response supplemental appropriations act: Congress and the executive branch

---

CRS-3
sometimes count or “score” appropriations differently. This year, there are major
differences in how OMB and the Congressional Budget Office (CBO) show the
allocation of funds provided in the Emergency Terrorism Response supplemental
appropriations measure that Congress approved on September 14, 2001. In all,
Congress appropriated $40 billion for responding to the September 11 terrorist
attacks, including $20 billion that was made available to agencies after the President
notified Congress how the funds would be distributed and a second $20 billion that
was made available only after Congress allocated the funds in a subsequent
appropriations act. Of the $40 billion total, $17.5 billion was allocated to the Defense
Department, of which $14.0 billion was from the first $20 billion and $3.5 billion from
the second $20 billion. An additional $374 million was allocated to the Department
of Energy for defense-related activities, of which $5 million came from the initial $20
billion and $369 million from the second. These amounts are part of the national
defense budget function. CBO and OMB differ in allocating these funds –
! CBO scoring conventions: CBO scores funds by fiscal year according to the
date when Congress makes funds available to the executive branch. Thus,
CBO allocates all of the initial $20 billion in supplemental funding to FY2001,
when the original appropriation was enacted, while it allocates all of the second
$20 billion to FY2002, which is when Congress approved a subsequent
appropriations measure distributing the funds among federal agencies. Under
this convention, CBO shows $14.0 billion of supplemental funds in the
Department of Defense budget for FY2001 and $3.5 billion in the budget for
FY2002 (all in budget authority).
! OMB scoring conventions: OMB, however, normally allocates funds by
fiscal year based on when the executive branch actually releases money to the
agencies. Following that rule, OMB allocates $4.3 billion to DOD in FY2001
because the President had sent two notifications to Congress distributing that
amount to DOD before the end of the fiscal year on September 30, 2001.
OMB allocates the $3.5 billion that Congress provided for DOD in the second
$20 billion to FY2002. OMB did not, however, include in either year’s DOD
budget the remaining $9.8 billion that was allocated to DOD out of the initial
$20 billion in supplemental funding. Instead, OMB shows those funds in the
Emergency Response Fund, a government-wide account into which the funds
were initially appropriated. Although OMB released all but a small amount of
the initial $20 billion before the budget was released on February 4, it does not
show funds released after September 30, 2001, in agency totals.
This report relies primarily on OMB data, so the figures shown here follow
OMB’s scoring conventions.

Part I: The FY2003 Defense Budget Request
The following section provides basic data on the FY2003 defense budget
request. Table 1 provides data on the national defense budget function and the
Department of Defense budget, including figures for budget authority and outlays in
current and constant dollars and percentages of real growth. For a definition of terms,
see the glossary at the end of this report.
Tables 2 and 3 show, respectively, budget authority and outlay figures for the
national defense budget function broken down by appropriations title.
Table 4 shows DOD budget authority broken down by military component —
i.e., the military services. Figure 1 graphically displays shares of DOD budget
authority by service for the FY2003 budget request.
Table 5 shows budget authority and outlays associated with Operation Desert
Shield/Desert Storm. In order to reflect accurately trends in defense funding, most
of the data in this report have been adjusted to exclude costs associated with the
Persian Gulf War, since that conflict was largely financed by U.S. allies. Table 5
allows the reader to compare the adjusted data published in this report with
unadjusted data published elsewhere.

Part II: Trends in Defense Spending
Part II provides data on trends in the defense budget that may be of particular
interest to Congress. In assessing trends, current levels of spending are often
compared to the peak levels reached during the defense buildup of the 1980s.
FY1985 was the peak year in budget authority for national defense, FY1987 was the
peak in the number of military personnel, and FY1989 was the peak in outlays.
Table 6 shows budget authority by appropriations title for selected years for the
period FY1976 through FY2007 in inflation-adjusted dollars and calculates
cumulative real growth or decline over the selected parts of that period. Figure 2
graphically shows trends in budget authority by title from FY1985 to FY2007.
Table 7 shows the trend in personnel levels for active duty forces, reserve
forces, and DOD civilians for FY1981 and selected years thereafter. Figure 3
illustrates the trend in active duty military personnel levels. Table 8 and Figure 4
show total active duty end-strength levels from FY1950-2003.
Table 9 shows the trend in major elements of force structure (Army and Marine
Corps divisions, Air Force tactical air wings, and Navy ships) for FY1980-2003.
Table 10 shows the trend in total national defense budget authority and outlays
in current and constant FY2003 dollars from FY1940 to FY2007.
Table 11 tracks national defense outlays as a share of gross national product
(GNP) and gross domestic product (GDP) from FY1910 to FY2007.
Figure 5 illustrates the trend in national defense outlays in constant FY2003
dollars from FY1910 to FY2007.
Figure 6 illustrates trends in national defense budget authority and outlays in
constant FY2003 dollars from FY1947 to FY2007.
Figures 7 and 8 illustrate trends in national defense outlays as a percentage of
GNP/GDP from FY1910 to FY2007 and as a percentage of GDP from FY1947 to
FY2007.
Table 12 shows the allocation of outlays by budget enforcement act category in
the federal budget in current year dollars, and Table 13 and Figure 9 show the same
data as percentages of total federal outlays. Figure 10 shows the allocation of federal
outlays in constant FY2003 dollars.
Table 14 follows the trend in DOD five- and six-year defense plans since 1987.
Finally, Table 15 shows defense spending of the top 25 foreign nations.

Sources: Current dollar FY1940-1975 budget authority figures from Department of Defense
Comptroller, National Defense Budget Estimates for FY1982, March 1983; all other current dollar
figures from U.S. Office of Management and Budget, Historical Tables: Budget of the United States
Government, Fiscal Year 2003, February 2002; constant dollar figures calculated by CRS using
deflators from Department of Defense Comptroller; figures on Desert Shield/Desert Storm costs and
receipts from Department of Defense Comptroller.
Notes: This and other tables in this report use OMB data which reflect enacted and proposed changes
in accounting for retirement benefits. Figures reflect (1) enacted accrual accounting for health care
benefits for over-65 military retirees beginning in FY2003; (2) proposed accrual accounting for health
care benefits for under-65 military retirees beginning in FY2004; and (3) proposed accrual accounting
for all civilian retirement benefits beginning in FY2003. Data in these tables also reflect OMB scoring
of funds provided in the Emergency Terrorism Response supplemental appropriations act approved in
September 2001. For an explanation of the impact of accrual accounting and of budget scoring
conventions, see the Introduction, above. Figures for FY1990 and beyond exclude costs and receipts
of Operation Desert Shield/Desert Storm. Figures prior to FY1976 are from DOD data that have not
been revised to reflect accrual accounting for military retirement in years prior to its adoption in
FY1985. Figures from FY1976 on have been revised by OMB to reflect accrual accounting.

Sources: Outlays, FY1910-1939, and GNP, FY1910-1929, from U.S. Department of Commerce,
Historical Statistics of the United States, Washington: GPO, 1975; outlays, FY1940-2007, and GDP,
FY1930-2007, from U.S. Office of Management and Budget, Historical Tables: Budget of the United
States Government, Fiscal Year 2003, February 2002.
Notes: This and other tables in this report use OMB data that reflect enacted and proposed changes
in accounting for retirement benefits. Figures reflect (1) enacted accrual accounting for health care
benefits for over-65 military retirees beginning in FY2003; (2) proposed accrual accounting for
health care benefits for under-65 military retirees beginning in FY2004; and (3) proposed accrual
accounting for all civilian retirement pension and health benefits beginning in FY2003. Data in
these tables also reflect OMB scoring of funds provided in the Emergency Terrorism Response
supplemental appropriations act approved in September 2001. For an explanation of the impact of
accrual accounting and of budget scoring conventions, see the Introduction, above. For this and
following tables, national defense outlay figures for FY1990 and beyond do not exclude Operation
Desert Shield/Desert Storm costs and receipts, since the amounts involved cannot be separated from
national economic activity or from total federal outlays. GNP before 1930, GDP thereafter.

Notes: Boldface denotes the future-year defense plan projected at the time of the budget submission. Figures for the budget year and following years reflect the Administration’s request and
future budget projections. Figures for the year immediately preceding the year for which funding is requested (e.g., FY2002 in the FY2003 request) represent the Administration’s estimate
of the amount enacted by Congress and may include proposed supplemental appropriations and rescissions. Figures for earlier years reflect changes to the enacted level due to congressional
action on supplemental appropriations and rescissions, transfers of budget authority from one year to another, and/or adjustments in contract authority for Working Capital Funds. The large
discrepancies in year-to-year estimates for FY1991 are due to substantial changes in accounting for Operation Desert Shield/Desert Storm. Figures in this table have not been adjusted to
exclude funding for Operation Desert Shield/Desert Storm. This and other tables in this report use OMB data which reflect enacted and proposed changes in accrual accounting for retirement
benefits after FY2003. Data in these tables also reflect OMB scoring of funds provided in the Emergency Terrorism Response supplemental appropriations act approved in September 2001.
For an explanation of the impact of accrual accounting and of budget scoring conventions, see the Introduction, above.

Notes: For information on a total of 167 countries and details on this data, see CRS Report RL30931,
Military Spending by Foreign Nations: Data from Selected Public Sources.
Military spending in this table is defined primarily by the NATO standard definition: cash outlays
of central governments to meet costs of national armed forces. This definition includes military
retired pay, which is excluded in the U.S. Office of Management and Budget’s definition of DOD
outlays. Therefore, the U.S. outlay numbers may be higher in this table than the reported DOD
outlay numbers in the rest of the report.

Part III: Definitions of Budget Terms2
The definitions that follow are taken from Office of Management and Budget and
Department of Defense publications.
Accrual Accounting – as applied to military retired pay, a method of recording costs
designed to reflect the liability of the federal government for the future
retirement costs of military personnel currently on active or reserve duty. First
used in FY1985 in DOD, this method of accounting represents a change from
the earlier practice in which the cost of military retirement was measured in
terms of actual payments to current retirees.
Appropriation – one form of budget authority provided by Congress for the funding
of an agency, department, or program for a given amount of time. An
appropriation provides funds for purposes specifically designated by Congress.
Funds will not necessarily all be spent in the year in which they are initially
provided.
Authorization – establishes or maintains a government program or agency by
defining its scope. Authorizing legislation is normally a prerequisite for
appropriations and may set specific limits on the amount that may be
appropriated for the specified program or agency. An authorization, however,
does not make money available, and sometimes appropriations are made without
having been authorized.
Budget Authority – legal authority for an agency to enter into obligations for the
provision of goods or services. It may be available for one or more years. An
appropriation is one form of budget authority.
Current/Constant Dollars – the cost of goods or services in current dollars is the
value in terms of prices current at the time of purchase – current dollars are also
referred to simply as “dollars” or as “then-year dollars.” The cost of goods or
services in constant dollars is the value adjusted to eliminate the effects of
changes in prices (usually due to inflation). Constant dollars, expressed in terms
of an arbitrary reference year (e.g., Fiscal Year 2003 dollars), are determined
by dividing current dollars by a “deflator” based on the prices in the reference
year. Constant dollars are used to assess growth rates of programs
independently of the effects of inflation. Growth rates in constant, inflation-
adjusted dollars are referred to as “real growth” rates.
Deficit – in the federal budget, the amount by which total federal budget outlays for
a given fiscal year exceed total federal revenues for that year.
Fiscal Year – a fiscal year in the federal government begins on October 1 and ends
on September 30 and is designated by the calendar year in which it ends. Thus,

Budget Primer by (name redacted) and (name redacted).

FY2003 begins on October 1, 2002 and will end on September 30, 2003. (Note
that the federal fiscal year ran from July 1 to June 30 until FY1977.)
National Defense Budget Function – one of the categories of the federal budget.
It consists of the Department of Defense (DOD) budget, which funds all direct
DOD military programs, and of a number of defense-related activities
administered by other agencies. These activities include atomic energy defense
activities funded through the Department of Energy, civil defense programs
administered by the Federal Emergency Management Agency, and the Selective
Service System. The DOD budget constitutes more than 95% of the National
Defense Budget Function.
Obligation – an order placed, contract awarded, service agreement undertaken, or
other commitments made by federal agencies during a given period which will
require outlays during the same or some future period.
Outlays – money spent by a federal agency from funds provided by Congress.
Outlays in a given fiscal year are a result of obligations that in turn follow the
provision of budget authority.
Unexpended Funds – budget authority that has been appropriated by Congress, but
remains unspent, representing future outlays. Unexpended funds, whether
obligated or as yet unobligated, are formally appropriated by Congress for
specific programs.
Unobligated Funds – budget authority that has been appropriated by Congress for
specific programs but that has not yet been pledged or obligated by contract.
