THE UNITED STATES NEEDS THE B-2 BOMBER
EXECUTIVE SUMMARY
Title: The United States Needs the B-2 Bomber
Author: Major Kenneth P. Hasenbein, United States Air Force
Thesis: Because the United States is withdrawing its forces from around
the world, it needs to maintain a modem strategic bomber force capable of
global reach, to deter aggression against U.S interests, and to successfully
wage war should conflict occur. The B-2 will be a vital component of that
force.
Background: The strategic bomber has been a crucial asset in our nations
conflicts since World War II. Besides being employed in our conventional
wars, bombers have also served as a leg of the strategic nuclear Triad.
Deterrence at all levels of conflict remains a component of the President's
National Security Strategy, and an important role for strategic bombers.
The world environment has changed dramatically in the last few years, and
with the end of the Cold War, the need for a bomber fleet has been
questioned. However, potential threats to the United States remain, and the
President has reaffirmed his commitment to the B-2, although in smaller
numbers than originally planned. The reduction of the B-2 fleet to 20
aircraft has forced the Air Force to revise proposed missions for the
aircraft. Because of the reduction in our forces around the world, it may be
necessary to strike a blow against a threat to our national interests or
against aggression before other force arrive on the scene. The B-2, with its
unique combination of stealth, range, payload, and accuracy, will be able to
strike "high value" targets in heavily defended enemy territory, which
neither the B-52 nor the B-I can accomplish. The issue of cost has
dominated the public debate involving the B-2 bomber. Emphasis on cost
alone has distracted attention from other important issues regarding the
need for the aircraft, its capabilities, or technological benefits derived
from the program. The B-2 is vital in today's strategic environment, and
will be a crucial asset in supporting the rational security strategy in the
future.
Recommendation: The United States Air Force must continue to actively
support the acquisition of the B-2, and make procurement of all 20 aircraft
a high priority.

THE UNITED STATES NEEDS THE B-2 BOMBER
The United States is currently withdrawing many of its forces from
around the world. In order to support the President's National Security
Strategy, the U.S. needs to maintain a modern strategic bomber force
capable of global reach, to deter aggression against U.S. interests, and to
successfully wage war should conflict occur. The B-2 bomber will be a
vital component of that force.
The B-2 bomber has been one of the most controversial aircraft ever built.
The existence of the aircraft was revealed in 1988 after years of secrecy.
Congress then subjected the bomber to intense scrutiny and criticized it for
its high cost. Also, the world environment has changed dramatically in the
last few years, and with the end of the "Cold War," the need for this aircraft
has been questioned. As this paper is written1 the debate continues to rage
on regarding the fate of the B-2 program. The President recently cut the
proposed B-2 procurement to 20 aircraft. This reduction has altered the
debate on the B-2. The Air Force has had to revise proposed missions for
the aircraft, and Defense Department leaders have had to address whether or
not such a limited fleet will be useful.
We will examine some of the issues involving the B-2 bomber, including
the role of strategic bombers, the capabilities of the B-2, and why the B-2
will be necessary in the strategic environment of the future.
THE ROLE OF STRATEGIC BOMBERS
Historically, long-range bombers have been used to strike targets of
strategic significance deep within an enemy's homeland. The Allies used
strategic bombing to devastating effect in World War II. Edward Jablonski,
in his book "Airpower, An Illustrated History of Air Power in the Second
World War," discussed the effects of U.S. strategic daylight precision
bombing as seen by German leaders. He said, "What the German
professionals--Minister of Arms and War Production Albert Speer and
Milch-- feared most was American bombing by day, aimed at specific war
industries." (7:47) In addition to targeting German industries, the U.S.
employed strategic bombers in massive raids against Japan. Many of Japan's
major industrial cities were demolished by American B-29 bombers
carrying incendiaries. (7:204)
During U.S. involvement in the Vietnam conflict, bombers were also used,
but results were less conclusive. Political restrictions on targets and
bombing halts gave North Vietnam badly needed respites from our attacks,
and diluted their effect. Nevertheless, the U.S. employed bombers on a
massive scale:
As in Korea, grand-strategic bombers were used for strategic
missions. By February 1969 some 105 B-52s from the Strategic
Air Command were flying about 1,800 sorties a month from Guam
(2,000 miles from the battlefields), Okinawa, and Thailand. (6:150)
Besides its employment in actual combat operations, the long-range
bomber has been a crucial asset in nuclear deterrence. Bombers have been
one of the legs of the strategic Triad (which also includes land-bled and
submarine-launched ballistic missiles). In fact, since the end of World
War II, the Air Force has emphasized aircraft optimized for the nuclear
deterrence role in its bomber design and development programs. (6:133)
The role of strategic bomber aircraft has continually evolved since World
War II. In each of our nation's conventional conflicts, the bomber has been
sought after for new missions that would take advantage of its long range
and heavy payload capabilities. With the advent of air refueling and
precision-guided munitions (PGM) or "smart bombs," the potential missions
for strategic bombers have expanded even further.
Historically the Air Force has treated tactical and strategic aircraft as
distinct entities, with relatively fixed roles. Although strategic bombers
have been used in tactical roles in certain situations in the past, today the
distinctions between tactical and strategic aircraft and missions have
blurred dramatically. In our recent conflict with Iraq the Air Force used the
B-52, a long-range strategic bomber, to strike the Iraqi Republican Guards,
arguably a "tactical" target. Conversely, the U.S. used the F-117 stealth
fighter, a so-called tactical aircraft, for precision strikes against targets
deep inside Iraq, Such targets generally would be considered "strategic"
targets. The next aircraft in the evolution of the bomber must encompass
features of both of these types of aircraft, and must be capable of striking
strategic as well as tactical targets.
STRATEGIC BOMBERS IN THE FUTURE
The U.S. Air Force is about to undergo a major reorganization. Specifically the Strategic Air Command and Tactical Air Command will merge into Air Combat Command. This merger is evidence that Air Force leaders recognize
that the future roles of aircraft will not be so narrowly defined as in the
past. The Air Force will employ a particular type of aircraft based on what
weapon system is best suited to strike a specific target, in an integrated
air effort with bombers and fighters working together.
Deterrence, in the classic sense of preventing nuclear war, remains one of
the elements of our national security strategy. In the future, nuclear
deterrence will still be a necessary role for strategic bombers as part of
the United States' strategic Triad. (18:25) However, nuclear threats may
not come from superpower adversaries. Because of the dissolution of the
monolithic Soviet Union, which was the predominant threat, such threats
will most probably come from smaller regional powers that have acquired
nuclear weapons.
The U.S. must also deter regional conflicts below the nuclear level. In a
recent editorial John T. Correll, Editor-in-Chief of Air Force Magazine,
summed up the argument for a deterrence strategy at all levels of hostility:
Unless the United States wants to spend the neet twenty years
fighting wars large and small, we had better hang onto
deterrence and fund it above the shoestring level. The changes
sweeping the world have made it possible to achieve deterrence
across the spectrum of conflict with less military power, but
that has already been factored into the new US defense strategy
and a much-reduced defense budget. (3:6)
If the U.S. military establishment is to adequately support the President's strategy, our long-range bombers must be capable of global reach. With the reduction in our military forces worldwide, it may be necessary to strike a blow against a threat to our interests or against aggression before other forces can travel to the scene. Long-range bomber aircraft based in the
United States must provide that capability. However according to a Rand
paper, this task would be difficult with our current bomber fleet:
The proliferation of modem air defenses throughout the world
has greatly restricted the ability of current bombers to overfly
modem defenses before they have been effectively suppressed.
Consequently, -1 and B-52H aircraft could not, with any
confidence, be used unsupported to deliver gravity munitions in
the early hours or days of a conflict or to participate in the
suppression of critical air defense assets. (4:10)
If current bombers could not penetrate heavily defended enemy territory,
possibly cruise missiles launched from aircraft such as the B-52 could
accomplish initial strikes against critical targets. However, because of the
need to avoid collateral damage, e.g., civilian casualties, the bombers would
need to strike those critical targets very accurately. Also, some mobile
targets would be hard to find ahead of time. Therefore, cruise missiles may
not be able to do the whole job:
Equipping such aircraft with stand-off cruise missiles would
permit them to engage many of these targets early in the
campaign; however, mission planners would need detailed and
accurate data on the location of enemy air defenses and on the
nature of each fixed target before cruise missiles could be
effectively employed. It is not clear that such data would be
reliably available in many potential short-warning scenarios.
(4:10)
Cruise missiles will be necessary, but there is still a requirement for an
aircraft with the ability to get through enemy defenses and strike `high
value' targets precisely. Neither the B-52 nor the B-1 possess that
capability. Additionally, even cruise missile carriers would neeel escort to
protect them while they fly to within launching range for their cruise
missiles.
THE POST-COLD WAR ENVIRONMENT
The Post-Cold War budgetary and political environments have been hostile
to the survival of the B-2. The fall of the Soviet Union and its satellites
has called into question the necessity of maintaining nuclear or even
conventional bomber forces. U.S. military leaders have had a difficult time
identifying and articulating any significant threats to U.S. national security.
As a consequence, military budgets have begun to fall, and weapon systems
have been cut, including the B-2 program.
The current, approved defense cutback plan was drawn up two years ago by
the Defense Department to deal with the reduction of the communist threat.
It was based on the disintegration of the Warsaw Pact, the reuniting of
Germany, and the withdrawal of Soviet forces from Eastern Europe. The
plan, called the "Base Force," included troop cuts of 25 percent, a 15 percent
cut in ships, and 30 percent cuts in aircraft, from U.S. forces. (9:34)
However, with the subsequent collapse of the Soviet Union itself, and
without other clearly defined threats, further cuts in the military are
probable in the near future. Representative Les Aspin, Chairman of the
House Armed Services Committee, suggested this possibility in an
interview. He said that after the collapse of the Warsaw Pact a 25 percent
reduction sounded about right, but without a Soviet Union, the base force
structure is out of date. (8:A10)
The fall of the Soviet Union has provided the primary justification for
budget reductions. However, though the overall threat from the former
Soviet Union has diminished, the remnants of its powerful military forces
are still a potential threat to the security of the United States. Russia and
the Commonwealth of Independent States (CIS), comprising 11 of the former
Soviet Republics, still maintain a strong nuclear capability. Robert Gates,
Director of the Central Intelligence Agency (CIA), expressed concern over
the unstable situation in Russia. He said, "There are so many challenges to
the leadership and the movement toward economic and political reform in
Russia that l think it would be premature to take our sights off a country
that still possesses 30,000 nuclear weapons." (5:A8). Additionally the CIS,
including Russia and Ukraine1 cannot agree on the disposition of the nuclear
weapons they have, or who should control them.
Besides the CIS, there are other potential adversaries throughout the
world. Iran is conducting an arms buildup, including development of a
nuclear capability. CIA Director Robert Gates stated, "Iran has embarked on
an across-the-board effort to develop its military and defense industries."
(13:29) Gates said Iran is developing weapons of mass destruction as well
as conventional arms, and is looking to Asian sources for nuclear and
chemical warfare technology. (13:29)
North Korea is also actively working on its own nuclear weapons. The
United States has confirmed extensive construction at a nuclear complex in
Yongbyon, 50 miles north of Pyongyang. (12:30) The North Koreans admit to
having a nuclear program, but claim it is for peaceful purposes only.
According to one estimate, however, North Korea will produce enough
plutonium by 1994 to start building nuclear weapons at a rate of two to
seven weapons per year. (14:118)
Nuclear capabilities are not the only possible threats to the United States. The spread of Islamic fundamentalism and state-sponsored terrorism could
also pose serious threats to U.S. national interests in the coming decades.
THE B-2 FILLS THE NEED
The B-2 will be a vital component of our strategic bomber force in the
uncertain strategic environment of the future. We will discuss the impact
of a reduced force of B2s, and the revised missions for a small fleet. We
will examine the unique combination of stealth, range, and payload
capabilities of the B-2, and why the aircraft is necessary to support our
national strategy. Finally, we will examine the issue of the cost of this
next-generation bomber.
President Bush has confirmed his commitment to the B-2. According to
the President's National Security Strategy of the United States, the B-2 will
serve as both a nuclear and conventional deterrent. The role of the B-2 is
specifically addressed:
The B-2 strategic bomber must be deployed so that the
flexibility traditionally provided by the bomber force will be
available in the future. The B-2 will also firmly plant our
aerospace industry in a new era of low-observable technology
and the bomber itself will have unique value across the spectrum
of conflict. (18:25)
Though the President has articulated a need for the B-2, he supports a
very small B-2 fleet. The Air Force originally proposed buying 132 B-2s,
which was subsequently cut to 7S aircraft. Then in his State of the Union
address in January 1992, President Bush terminated the B-2 program at 20
aircraft. Currently, Congress has funded only 15 of the proposed 20 B-2s.
In anticipation of a fleet of only 20 aircraft, the Air Force has redefined the mission for the B-2. In addition to deterrence, the aircraft will be used for critical conventional operations. Discussing this new emphasis for the B-2, a recent article in Aviation Week & Space Technology said the
following:
In a revised mission statement, the B-2's new assignment will
be to `hold at risk and, if necessary, attack an enemy's war-
making potential, especially...time critical targets.' Such targets
include facilities to produce, support and deliver nuclear,
chemical and biological weapons. (1:33)
Secretary of the Air Force Donald Rice discussed the size of the B-2 force
and its utility in an interview:
I think, with 16 operational aircraft, two squadrons of eight
each, we will be able to have the B-2 perform a whole range of
missions that we had originally envisioned. Obviously, we won't
have the numbers we required for some of the larger-scale
scenarios that one could envision. So we will have to devote the
B-2s to those most critical, most time-sensitive targets where
the defenses are the toughest. And we'll use them, much as we
did with the F-1 17 in the Persian Gulf, for the toughest jobs.
(10:30)
In another statement released by Secretary Rice, he said, "Fielding the B-2,
even in smaller numbers, reaffirms our earlier decisions to invest in stealth
and provide a multidimensional, multimission bomber force for the future."
(17:17). Air Force Chief of Staff Merrill McPeak, also supported the 20
airplane fleet of B-2s:
...A force of 20 B-2s, which will probably work its way down to
something like 16 that are combat-coded and available for
operational use, is a heck of a capability...This is a force that can
get anywhere in the world in a few hours. (17:17)
To accomplish its critical missions, the B-2 must be able to get past
heavy enemy defenses. The B-2 will do this through the "stealth"
characteristics inherent in the design of the aircraft. "Stealth" involves
reducing the radar, heat and other "signatures" of the aircraft, making it
less visible to the enemy. Stealth allows the aircraft to penetrate enemy
territory and deliver its weapons with a reduced probability that it will be
detected, engaged by the enemy, and shot down. Stealth technology already
has been successfully battle tested in the Persian Gulf war, with the F-1 17.
One example of the proven value of stealth in war was reported in "Airman
Magazine." The article described an effort to destroy an Iraqi nuclear
reactor facility south of Baghdad:
In a strike package of 60 attack, fighter, Wild Weasel and
electronic warfare aircraft, plus 15 aerial tankers, failed in
their attempt to take out the facility.
Yet eight F-1 17's carrying laser-guided bombs and supported by
only two tankers destroyed three of four reactors in one raid.
(11:25)
Stealth, or "low-observable" technology is the key advantage of the B-2.
Overall, the B-2 has done well in demonstrating its low-observable
characteristics to date. Even though the B-2 is not "invisible" to enemy
radar in every single frequency of the radar spectrum, it is a quantum leap
over earlier generations of bomber aircraft, and would be very difficult to
detect. An Air Force publication on B-2 survivability said the following:
The B-2 is obviously not invisible. But what is needed for
successful air defense against the B-2 is detection, tracking, and
kill capabilities at relatively long operating ranges (e.g., 25 to
200 miles depending on the style of defense). At such ranges,
the various signals available from the B-2 are generally very
weak, and easily lost in the noisy background or obscured by
ground clutter, weather, clouds, and other phenomena. (16:9)
Thus, B-2s could be employed without the need for other aircraft to escort
them or to suppress enemy defenses for them. The B-2, with its unique
combination of stealth, range, payload, and PGM capabilities, will allow it
to take on missions of a strategic and tactical nature in a conventional
conflict that previously only combination of aircraft could accomplish.
Although the B-2 could be employed without escort, this idea is not meant
to suggest that the B-2 will "win" any conflict alone. The B-2 will operate
as only one asset in a joint effort during any sustained conflict. Prior to
the introduction of other forces, the B-2 could serve as a leading strike
last $14.5 billion, we would have had the last 55 B-2s of a 75 aircraft fleet.
Although the 75 aircraft fleet is a moot issue, the unit fly-away cost for
the last 60 aircraft would have been $338 million. (15:39) The point is that
we have seen figures ranging from $811 million to $338 million per
aircraft, all for the same final number of aircraft. Too much emphasis on
the cost issue has diverted attention from other relevant issues such as the
need for the aircraft, its capabilities, and other benefits derived from the
program.
Although the aircraft is expensive, we are getting more than just some
number of aircraft for the total program cost. There are numerous
technological spin-offs from the research and development associated with
the program that will have uses in other areas. The report "Why" the B-2
discussed some of the new technologies developed for the B-2, and their
applications:
The most obvious of these is stealth technology, which almost
certainly will be built into all future military aircraft to one
degree or another. Others include fabrication of large composite
structures, techniques for testing and quality control of
composite structures, and electronic product definition and
design (19:15)
ALTERNATIVES TO THE B-2
One alternative to the B-2 would be to eliminate the program and
not build any new strategic bomber. As we have seen, however, there are still
potential threats to our national security. In addition, our national strategy
calls for the B-2, and current aircraft cannot fulfill the role. Long lead
time would be a problem should our national leaders then decide to build
another new bomber. If the B-2 program was canceled, another new bomber
asset in the opening days of a conflict. The B-2 will be able to take out
certain targets early in hostilities before air superiority has been achieved.
This contribution would enhance our overall chances for success. Of course
the B-2 could carry out single raids, such as the one against Libya, as well.
One of the most significant-aspects of the B-2 debate is the cost of the
aircraft. However, the cost figures of the aircraft can be deceiving, since
there are several ways of computing cost. For example, the typical way of
reporting the cost of the B-2 has been to divide the total program cost by
the number of aircraft to be purchased. For a 75 aircraft program, the total
cost would have been $60.8 billion in Fiscal Year (FY) 91 dollars. (15:35)
That would be an approximate cost of $811 million per aircraft. However,
that cost includes the research and development for the aircraft, the setup
of the production line and tooling, and construction of facilities to test the
B-2. (15:36)
A more relevant cost figure however, is the unit fly-away cost of the B-2,
which is the actual production cost of each aircraft excluding research and
development costs. Obviously, these costs will also vary depending on how
many B-2s are finally procured. Had we stuck with a 75 aircraft program,
the average fly-away cost for each aircraft would have been $437 million
each. (15:36) This represents only a little over half of the $811 million
figure. If the Air Force only receives the 15 aircraft that are currently
funded, the fly-away cost will be $939 million each. (15:39) This cost
takes into account the $6.0 billion in costs associated with shutting down
the program. According to published figures, the savings achieved by
cutting the B-2 program at the proposed 20 aircraft will be $600 million in
Fiscal 1993 and a total of $14.5 billion through Fiscal 1997. (2:20) For that
could not be fielded until well into the next century, because of the time
required for the acquisition process.
Updating the B-52 or the B-1 is another alternative. However, the B-52
has been operational since the 1 950s, has no stealth capability, and will
continue to grow more expensive to maintain as it gets older. The B-1 lacks
the stealth characteristics also, as well as effective electronic defenses
that would allow it to penetrate air defenses in the coming decades.
Additionally, neither the B-1 nor B-52 have the combined range and weapons
capacity of the B-2.
In a conventional scenario, we will compare aircraft in a high altitude
flight profile. The B-2 combines an unrefueled range of 6700 nautical
miles, with a payload of 80 MK-82 bombs, totaling 40,000 pounds. In a
similar comparison, the B-52H has a range of only 5800 nautical miles with
a payload of 51 MK-82 bombs, for a total of 25,500 pounds. The B-1 can
carry 56 bombs, 28,000 pounds, for a 4950 nautical mile range. (19:10) A
high-low-high profile includes a 1000 nautical mile low level portion of the
mission. If we compare aircraft in a high-low-high profile, we get similar
results. Overall, the B-2 has 55 percent better fuel efficiency than either
the B-52H or the B-1 on the high-low-high profile. (19:10) The B-2 will be
able to strike targets at greater distances from its home base, with more
payload than either the B-52 or the B-1, using less tanker support.
Fewer lives will be put at risk by using the B-2 for a given mission,
compared to the B-52 or B-1. The B-2 has only a two-man crew, versus four
crewmembers for the B-1 and six for the B-52 (five without the gunner).
Also, if B-52s or the B-1 s were to overfly heavily defended enemy territory,
they would require support to suppress enemy defenses that could put
additional aircrews at risk.
THE U.S. NEEDS THE B-2
The United States is reducing its force presence around the world. In
order to support the President's National Security Strategy, the U.S. needs a
strategic bomber force capable of deterring aggression against U.S.
interests anywhere in the world, and successfully striking an adversary
should conflict occur. As we have seen, the B-2 is a unique aircraft with
capabilities that will allow it to perform many missions, and will be a vital
component of that bomber force.
The need for the B-2 aircraft has been questioned because of a rapidly
changing world environment, and because of its high cost. Unfortunately,
the public image of the B-2 has been defined by its cost without regard to
the value obtained for that cost, almost to the exclusion of all other
factors. In this period of shrinking military budgets and election year
politics, the controversy surrounding the B-2 program continues and the
program could change again. The President's announcement during his State
of the Union address ended the B-2 program at 20 aircraft, and forced the
military to take another look at the viability of a small B-2 fleet. As we
have seen, though proposed missions for the aircraft have been revised, the
B-2 bomber is vital in today's strategic environment and will be a crucial
asset in supporting our national security strategy in the future.
