Defense Budget for FY2002:
Data Summary, Final Version
Summary
This report outlines the amended FY2002 defense budget request from the Bush
administration, delivered to the Hill in June 2001. The report presents defense budget
data in a manner designed to provide various perspectives on U.S. military spending.
Part I presents basic data on the amended Bush Administration FY2002 national
defense budget request, including data 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, defense
outlays as a share of gross domestic product and 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 FY2002:
Data Summary, FinalVersion
Introduction
This report is designed to be a readily accessible source of facts and figures on
the FY2002 national defense budget. Part I provides basic data on the amended Bush
Administration’s FY2002 national defense budget request of June 2001, including
data on budget authority and outlays for the Department of Defense (DOD) and for
the national defense budget function (Function 050). Operation Desert Shield/Desert
Storm figures are included in Part I. Part II shows trends in national security
personnel and force structure. Also in this section, trends in overall defense spending
are shown – including figures on 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. A table of military spending by foreign nations is
also included. Part III defines key defense budget terms.
The significance of long-term defense spending trends depends to a large extent
on how budgetary data are interpreted. 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 – most 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.
These data do not include funds from the FY2001 Emergency Appropriations
Act for Recovery from and Response to Terrorist Attack on the United States (H.R.
2888), which provides $40 billion in emergency spending to be allocated by the
Administration in consultation with Congress. The funds are to be spent for the
following purposes:
!federal, state, and local preparedness for relief from and for responding to the
attack;
!support to counter, investigate and prosecute domestic and international
terrorism;
!increased security for transportation;
!repairing damage to public facilities and transportation systems; and
!supporting national security.
CRS annually prepares a number of issue briefs and reports on specific weapon
programs and other defense issues, including:

Part I: The FY2002 Defense Budget Request
The following section displays basic data on the FY2002 national defense budget
request. Table 1 provides figures for 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 amended FY2002 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 as Congress considers aspects of U.S. defense policy. 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 the period FY1985
through FY2006 in inflation-adjusted dollars and calculates cumulative real growth
or decline over the FY1985-2002 period. Figure 2 graphically shows trends in
budget authority by title from FY1985 to FY2006.
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. Total active duty end-
strength for FY1950-2002 is exhibited in Table 8 and shown from FY1987-2002 in
Figure 4.
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 FY1980-2002.
Table 10 shows the trend in total national defense budget authority and outlays
in current and constant FY2002 dollars from FY1940 to FY2006.
Table 11 tracks national defense outlays as a share of gross national product
(GNP) and gross domestic product (GDP) from FY1910 to FY2006.
Figure 5 illustrates the trend in national defense outlays in constant FY2002
dollars from FY1910 to FY2006.
Figure 6 illustrates trends in national defense budget authority and outlays in
constant FY2002 dollars from FY1947 to FY2006.
Figures 7 and 8 illustrate trends in national defense outlays as a percentage of
GNP/GDP from FY1910 to FY2006 and as a percentage of GDP from FY1947 to
FY2006.
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 FY2002 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 50 foreign nations.

Deflators and figures on Desert Shield/Desert Storm costs and receipts from Under Secretary
of Defense Comptroller; and CRS calculations.
Notes: Figures for FY1990 and beyond exclude costs and receipts of Operation Desert
Shield/Desert Storm. Figures for FY2001 include the July 2001 supplemental appropriations
and exclude the September 2001 counterterrorism supplemental appropriations. FY2002-
2006 reflect Administration projections. No data are available for budget authority prior to
FY1945. The figures for budget authority reflect one unavoidable statistical discontinuity.
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 the Office of Management and Budget to reflect accrual
accounting. The difference, however, is relatively small and does not significantly affect the
figures as an indication of trends in national defense funding.

exclude Operation Desert Shield/Desert Storm costs and receipts, since such the amounts involved
cannot be separated from national economic activity or from total federal outlays. GNP before 1940,

Notes: Boldface denotes the future-year defense plan projected at the time of the budget submission. Figures for the year immediately preceding the year for which funding is requested (e.g.,
FY1987 in the FY1988 request) represent an estimate and may include proposed supplemental appropriations or rescissions. Actual figures reported in following years may differ because
of congressional action on supplemental appropriation requests, 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 methods for Operation Desert Shield/Desert Storm. Though the figures for FY1990-92
presented here have been adjusted to exclude funding for Operation Desert Shield/Desert Storm, these adjustments do not eliminate all of the discrepancies for FY1991.
* In FY2002 – unlike previous years – the numbers beyond FY2002 are not backed up by a detailed Future Years Defense Plan (FYDP). The figures for years beyond FY2002 represent
no real growth, from the FY2002 requested level.

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 are higher in this table than the reported DOD outlay numbers in the rest of the report. The
difference in the outlay numbers in this table and the others is military retired pay.
* These estimates are based on purchasing power parity (PPP) estimates. PPPs measure the relative purchasing
power of difference currencies over equivalent goods and services. Proponents of this method argue that it
better accounts for the substantial differences in relative prices for defense goods.
E These data were estimated by IISS and not based on reported data from the individual country.
** Rank ordering is as stated in the Department of State’s, WMEAT report. Rankings are estimated even when
a specific expenditure level is not provided, as in the cases of Libya and Burma.



Part III: Definitions of Budget Terms**
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 2002 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,


**For a complete glossary on defense budget terms, see CRS Report RL30002, A Defense
Budget Primer by Mary T. Tyszkiewicz and Stephen Daggett.

FY2001 began on October 1, 2001 and will end on September 30, 2002. (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.
