April 15, 2002, will
mark the golden anniversary of the B-52 Stratofortress.
Fifty years earlier, at Boeing Field, Seattle, the
YB-52, serial No. 49-0231, took off for the first time.
No one--not even pilots A.M. "Tex" Johnston
and Guy M. Townsend--could have imagined that the gigantic
eight-engine bomber would serve so well, so long, and
in so many roles.
Certainly no one dreamed that the B-52 would be in
action over Afghanistan in the fall of 2001. But it
was.
The B-52 began projecting global airpower with an
epic, nonstop round-the-world flight of three aircraft
in January 1957, and it continues to do so today. The
original B-52 design was a triumph of engineering.
However, its success has depended mostly on the talented
individuals who built, flew, maintained, and modified
it over the decades.
Called to combat once again in the War on Terror,
the B-52 continues to give front-line service in a
variety of roles. What's more, its career is assured
for at least 20 years more. Early in its eventful life,
the B-52 was given the affectionate nickname "BUFF," which
some say stands for Big Ugly Fat Fellow.
The B-52's stunning longevity is matched or exceeded
by its versatility. In the early years it functioned
exclusively as a high-altitude strategic bomber, built
to overpower Soviet defenses with speed and advanced
electronic countermeasures and deliver nuclear bombs
totaling up to nine megatons in explosive power. When
Soviet air defenses improved, the B-52 broke new ground
by carrying Hound Dog stand-off missiles designed to
suppress enemy defenses.
However, when Soviet surface-to-air missiles downed
the U-2 spyplane piloted by Francis Gary Powers, the
B-52 was given new tactics; it was to evade enemy radar
by skimming over the terrain at altitudes of 300 feet
or less. Almost intolerable stresses were placed on
the airframe and the crews in this flight regime, but
the rugged B-52 just flexed its wings and pressed on
with its nuclear mission.
Along the way, the B-52 was tasked with many missions
that had not been envisioned, including photoreconnaissance
of Soviet shipping and carriage of systems ranging
from anti-ship missiles to high-speed reconnaissance
drones.
The
Vietnam Shift
The Vietnam War brought another significant change
to the bomber. Part of the B-52 force was serving as
Strategic Air Command's long rifle aimed at the heart
of the Soviet Union. However, in Southeast Asia, the
big bombers became flying artillery, backing up ground
forces whenever needed. Crews who had been trained
in long-range nuclear penetration tactics now became
the arbiters of the battlefield, called on by commanders
for close-very close-air support.
After the Vietnam War, the B-52 was modified to handle
new weapons, including sophisticated air-launched cruise
missiles and precision guided munitions, but it retained
its legendary power to flatten enemy ground forces
with tons of World War II-type bombs. The B-52's defensive
capability received comparable upgrades so that, even
in the age of stealth, it serves a major combat role.
In great part, the B-52's longevity and the versatility
resulted from the actions of Gen. Curtis E. LeMay,
both before and after he became the SAC commander in
chief (and later USAF Chief of Staff). At the dawn
of the Cold War, defense budgets were tight and long-range
missiles were seen as the coming thing. However, LeMay
altered the calculus. When offered a modified B-47
design that met most of the requirements for the proposed
B-52 mission at far lower cost, LeMay declined angrily,
insisting that he wanted an aircraft large enough to
accommodate later developments, particularly in electronic
countermeasures equipment.
In essence, LeMay had defined a new age in airpower,
when aircraft were to be seen as "platforms" able
to be modified over the years to take the systems that
new weapons and new missions demanded. There were the
usual protests at the time over high unit cost of the
prototypes, but no one could have guessed that the
costs would be amortized over no fewer than five and
possibly as many as seven decades.
The BUFF's first mission was one for the ages. LeMay
made it the linchpin of the American strategy to deter
war by making SAC so strong that the Soviet Union would
not dare launch a first strike on the United States
or its allies. The quick response capability of the
B-52 and the undeniable skill of its flight crews were
made obvious to Soviet military and political leaders
by means of its constant exercises and record-setting
flights.
Nikita's Case of Nerves
SAC and the B-52s succeeded in that mission, and never
more memorably, during the October 1962 Cuban Missile
Crisis. As revealed by Soviet Premier Nikita Khrushchev
in his memoirs, the presence of nuclear-armed B-52s
on orbit outside the borders of the USSR made him think
twice and then again about the wisdom of challenging
the United States. Eventually, Moscow backed down.
Roger Ferguson, a B-52 navigator during the crisis,
recalls that the mission briefings were deadly serious
and that plans called for B-52s to enter Soviet airspace
at a given point every 12 minutes. Security was suffocating.
When Ferguson's crew raced out to their loaded B-52
to launch, they were forced to hit the deck, spread-eagled,
by an eager rifle-toting airman. The BUFF commander
had forgotten the countersign. It was funny--but not
until much later.
There are many apocryphal stories about aircraft being
designed on the back of envelopes, but it is absolutely
true that the original design for what became the B-52
was created over one weekend in the Van Cleve Hotel
in Dayton, Ohio.
On Thursday, Oct. 21, 1948, a group of highly talented
Boeing engineers, including George Schairer, Vaughn
Blumenthal, and Art Carlsen, were gathered to present
the latest version of a straight-wing turboprop bomber
design to Col. Henry E. "Pete" Warden, a
project officer at Wright-Patterson AFB, Ohio. Unknown
to them, acting on his own authority, Warden had been
urging Pratt & Whitney to build the J57 jet engine.
Warden suggested to the Boeing engineers that they
scrub the turboprop bomber and come up with a swept-wing
pure jet engine aircraft using the J57.
The
Boeing engineers were not exactly starting from scratch.
They had learned much from the six-jet-engine, swept-wing
Boeing B-47 and were aware that there would soon be
major improvements in in-flight refueling systems,
including what would become the KC-135 jet tanker and
the Boeing flying boom in-flight refueling system.
The team members notified Warden that they would be
ready with a presentation on Monday morning. Their
boss, Edward C. Wells, arrived from Seattle, and with
two other Boeing employees, H.W. Withington and Maynard
Pennell, in town on other business, they worked continuously,
with plenty of telephone calls to Seattle, and succeeded.
In addition to three-view drawings and a 35-page proposal,
they presented to Warden a silver balsa wood model
of the new bomber, carved by Wells himself.
The proposed aircraft bristled with advances over
the B-47. The earlier aircraft had a thin, narrow-chord
wing, bicycle landing gear, and a structure designed
using World War II criteria. The B-52's huge wing featured
4,000 square feet of wing area, but it was flexible
enough to deflect through a 32-foot arc. It had an
ingenious and top secret crosswind main landing gear
that allowed landing in a direct crosswind of 43 knots.
It also made use of the most modern construction techniques
available.
Boeing built two prototypes-first the XB-52 and then
the YB-52. The second prototype was actually the first
to fly because the XB-52 had suffered damage in a full
pressure test of its pneumatic system. The test ripped
out the wing's trailing edge. Production approval preceded
the first flight, however, and the first batch of 13
B-52As were ordered in February 1951. These differed
from the prototype aircraft in a number of ways, the
most obvious being the change from the B-47-style tandem
cockpit layout to conventional side-by-side seating
for the pilots. Only three B-52A models were built,
the remaining 10 being completed as RB-52Bs. (The RB-52
was a dual-role aircraft, designed to have a reconnaissance
capability gained from a two-man pressurized capsule
in the bomb bay.) The third of the A models, #52-003,
would have a distinguished career as a mother ship
for the North American X-15 and many other test vehicles.
Designated NB-52A, it served until 1968 and is now
at the Pima Air and Space Museum in Tucson, Ariz.
The Coming of the BUFF
The first operational aircraft was an RB-52B, delivered
to the 93rd Bomb Wing at Castle AFB, Calif., by its
commander, Brig. Gen. William E. Eubank Jr., on June
29, 1955. The 93rd transitioned from B-47s to B-52s
and at the same time established the 4017th Combat
Crew Training Squadron for B-52 crew training.
The sight of the first operational B-52 coming in
to land brought mixed emotions. It was a beautiful
airplane, but qualifying for even a copilot position
required a minimum flying time of 1,000 hours. As partial
compensation, junior pilots often flew a Lockheed T-33
as chase aircraft on early B-52 missions. During one
of these, the right outrigger gear of a landing B-52
failed to extend. After exhausting all the in-flight
emergency procedures, the tip gear stayed up and the
BUFF came in to land. Determined that no incident would
occur, Eubank was driven in a jeep alongside the landing
aircraft and personally grabbed the wingtip to make
sure that it did not touch the ground.
The B-52C, D, E, and F models followed in quick succession.
These were similar in external appearance and differed
primarily in the engine series, fuel capacity, and
the bomb-navigation and fire-control systems.
During the first years of the Vietnam War, the Air
Force deployed only B-52Fs to the theater. The B-52Fs
could carry 51 of the standard 750-pound bombs--27
internally and 24 on pylons. In time, the demand for
B-52 bombing sorties became so great that the entire
B-52D fleet was prepared for conventional warfare by
means of a high-density bombing system modification
called "Big Belly." This increased the bomb
bay capacity to 42 separate 750-pound bombs or 84 500-pound
bombs. It could still carry 24 bombs externally, for
a maximum bomb load, internal and external, of 108.
The nuclear bombing capability was retained.
The B-52 G and H models differed significantly in
appearance from their predecessors, having a shorter
vertical fin and rudder. The G was designed especially
for flight at low levels and was considered by pilots
to be more difficult to fly than others in the series
because the ailerons had been removed and lateral control
was by spoilers only. Unlike all previous models, which
used conventional fuel bladders, both the G and the
H models had wet-wing fuel tanks, greatly increasing
their internal capacity. This was a disadvantage in
combat; during Linebacker II operations in 1972, nine
Ds were hit by SAMs but were still able to land. More
vulnerable because of the wet wing, all but one of
the six B-52Gs hit by SAMs crashed.
More Power
The H model was modified to be easier to control and
was easily distinguished by powerful new TF33 turbofans.
Compared to power plants on the G models, these offered
about 30 percent more power. The 744th and last B-52,
an H model, was delivered Oct. 26, 1962. The B-52H
is now the only BUFF in active service.
It still demonstrates the versatility of the basic
design. The B-52H has been modified to accept the new
AGM-154 Joint Standoff Weapon and AGM-158A Joint Air-to-Surface
Standoff Missile, upgraded AGM-86C/D Conventional Air
Launched Cruise Missiles, and an offensive avionics
system fitted with new computers. The old Inertial
Navigation System is being upgraded with the Ring Laser
Gyro INS, and the electronic countermeasures equipment
is getting color touch-screen technology.
The buildup in numbers of the B-52 came as SAC was
in a period of profound transition. In 1958, the B-47s
had reached a peak with about 1,360 in operation, but
their numbers declined rapidly thereafter, and most
were out of operational use by late 1965. While original
plans had called for a fleet of only 282 B-52 aircraft,
the demand built steadily, and by 1962, the Air Force
had deployed no fewer than 639 operational B-52s.
As B-47 and B-36 units converted to B-52s, there were
some unusual personnel problems. Some combat crews
with years of service together, many with individuals
who had earned spot promotions, were broken up and
spot promotions lost. Some especially skilled crew
members had "spots on spots"-two spot promotions.
When the spots were taken away, lieutenant colonels
became captains overnight.
As a result, there were often unseemly scrambles among
aircraft commanders to select the best talent for their
new crews. In SAC, promotions depended in great part
upon crew performance, and every new B-52 crew wanted
the best people at each of the six positions--aircraft
commander, pilot, radar/navigator (essentially, the
bombardier), navigator, Electronic Warfare Officer,
and gunner. (A great and honorable tradition ended
in 1991 when USAF eliminated the B-52 gunner's position,
a victim of new technology that made aerial gunnery
passé.)
Introducing the B-52 entailed far more than teaching
crews how to fly a new aircraft. The wingspan of 185
feet and a gross weight reaching 488,000 pounds on
later models meant that new runways, taxiways, hangars,
refueling facilities, and maintenance docks had to
be provided at many bases. The planning problem was
increased in 1957 when the threat of Soviet missile
attack made it imperative to disperse B-52s to a larger
number of bases to complicate Soviet targeting.
On Alert
By Oct. 1, 1963, there were 42 B-52 squadrons stationed
at 38 bases. The dispersal made it easier for SAC to
try to reach its goal of having one-third of its force
on ground alert at all times, but the new situation
imposed severe problems on training, maintenance, and
logistics.
SAC
was without question the most influential component
of United States armed forces, and it routinely received
a large share of the military budget. But even a large
budget and good management could not solve all the
problems, and the usual last resort was to take a solution
out of the hides of the crews. The alert system was
one of these last resorts, intended to solve the problem
of maintaining a large proportion of the force instantly
ready for war.
While the alert system was undeniably effective, it
was also cruel to family life. The ordinary working
week lasted 60 to 80 hours, and there were lots of
temporary duty separations. The alert system added
to these hardships. Sometimes the stress of life in
SAC became too much and divorces resulted, but for
the most part, wives and children pulled their "tours
of duty" with the same courage as did the crew
members.
The alert concept was introduced on Oct. 1, 1957.
Under its terms, B-52s were required to get airborne
within 15 minutes of the order to take off. At the
time, it was widely accepted that the USSR had a great
advantage in ballistic missiles that could strike US
targets within 30 minutes of launch. With immediate
warning, a 15-minute alert meant that the B-52s would
just have time to get off to retaliate for the missile
attack.
Crews on alert status were expected to remain together
and be close enough to meet the 15-minute demand. Aircraft
were "cocked," that is, ready for engine
start, and experienced crews could have the engines
running within two minutes of an alarm and be taxiing
within five minutes.
The alert plan contained an unacknowledged problem
that was unique in warfare: a warrior's family was
in greater danger than the warrior himself. The chances
were that the warrior would return from a combat mission
only to find that he had lost his family to the enemy
attack. There were evacuation plans, but civil defense
was never really embraced by the United States as it
had been in the Soviet Union. Tension remained high
throughout the Cold War despite the frequency of training
alerts, for the crews never knew which one might be
the real thing.
The routine and schedule of alert duty varied from
base to base and over time, but a crew might expect
to pull one week of alert out of the month, in addition
to all their other many training requirements. In the
early days, the "alert shacks" were improvised,
but later they were well-built and relatively comfortable.
In their "free" moments the crews could use
the usually Spartan recreational facilities or work
on correspondence courses, but much of the time was
spent in studying their Positive Control Procedures
and their specific war plan mission. The crews had
to be as concerned about Positive Control Procedures
and the associated paperwork as they were about the
war plan mission, for any failure with the procedures-or
loss of the paperwork-meant serious disciplinary action.
The B-52 did not go to war for nearly 10 years after
it entered service, but its entry into the Vietnam
War would have a drastic impact on SAC's ability to
maintain a substantial percentage of its force on alert.
First Blood
The BUFF entered combat from Andersen AFB, Guam, on
June 18, 1965. Some 27 B-52Fs of the 7th and 320th
Bomb Wings were ordered to attack Viet Cong forces
about 40 miles north of Saigon. It was the first Arc
Light operation. The results were tragically disappointing.
Two B-52s were lost in a midair collision during a
360-degree timing adjustment turn. Eight crew members
lost their lives. A third aircraft was diverted. The
remaining BUFFs dropped their bombs on an area that
the Viet Cong had just vacated.
Despite
the inauspicious beginning, the Arc Light campaign
proved to be so valuable that the demand for sorties
went up from an initial rate of 300 per month at the
beginning of 1966 to a peak of 3,150 per month in 1972,
in the successful effort to contain the North Vietnamese
spring offensive. The effectiveness of the force was
enhanced with the introduction of the B-52D as the
standard bomber and the introduction of the Combat
Skyspot radar-assisted ground-directed bombing system.
U Tapao Royal Thai Air Base was brought into operation,
enabling the Air Force to conduct B-52 missions with
greatly reduced en route times. Sorties were extended
beyond Vietnam to Laos and Cambodia. The strategic
nuclear bomber had been turned into a flexible, on-call
tactical bomb delivery system.
The B-52 distinguished itself many times during the
Vietnam War, but two efforts stand out above all. The
first is the battle of Khe Sanh, where new tactics
devastated the North Vietnamese besiegers in 2,548
sorties that dropped 59,542 tons of bombs and, in the
words of Army Gen. William Westmoreland, "broke
their [the enemy's] back."
The second was Operation Linebacker II, when in 11
days of bombing, B-52s smashed the defenses of Hanoi
and Haiphong and forced North Vietnam to negotiate
peace in Paris. The B-52s flew 729 out of 741 planned
sorties and dropped 15,000 tons of bombs. Fifteen BUFFs
were lost-about two percent of the force. The action
proved that the B-52, supported by tactical air assets,
could meet and defeat the enemy. The results have caused
many to wonder what the world might be like if the
B-52s had been unleashed in 1965, when the target areas
were virtually undefended.
All told, the BUFF force flew 126,615 sorties during
eight years of Arc Light. The B-52, initially a desperation
weapon thrown in when there was nothing else available,
grew to become the final instrument of the war.
After Vietnam, the B-52s returned to service in the
Cold War. As the years passed, attrition and economics
pared the B-52 fleet down until, by 1991, only B-52Gs
and Hs remained in service, with the exception of an
NB-52B serving as mother airplane at Edwards Air Force
Base in California.
Desert Duty
Operation Desert Storm called the old warrior into
action once more, with about 80 B-52Gs operating from
the United States and four
overseas locations. History was made on Jan. 17, 1991,
when seven B-52Gs from the 2nd Bomb Wing at Barksdale
AFB, La., completed what was then the longest combat
mission in history--35 hours. The bombers flew from
their US base to attack Iraqi targets with 35 AGM-86C
Conventional Air Launched Cruise Missiles. Poststrike
reconnaissance revealed that 33 CALCMs found their
target.
The B-52 missile attack was followed up with the first
low-level attack in SAC history. After three decades
of practice, B-52s swept in at less than 300 feet above
the ground to bomb four Iraqi airfields and an important
highway. Then, after these glamorous forays, it was
back to textbook duties from the Vietnam War era, with
three-ship cells of B-52s bombing from above 30,000
feet. The B-52s would put down about 150 bombs in a
tight, devastating pattern that killed troops in the
target area and demoralized those adjacent to it. The
B-52s were assigned other missions as well, but the
main thrust of their attacks was the decimation of
Iraqi troops with conventional M117 750-pound bombs
and cluster bomb units. All told, the BUFFs flew more
than 1,600 sorties and dropped more than 25,000 tons
of ordnance. No B-52s were lost to enemy action, but
one crashed in the Indian Ocean on its way back to
Diego Garcia, with the loss of three crew members.
The BUFF, now a hardened combat veteran, returned
to war in February 1999, in Operation Allied Force.
Aircraft were sent first from Barksdale and later from
Minot AFB, N.D. Combat operations began in late March,
with six B-52s launching CALCMs. Heavy raids by B-52s
on Yugoslav army units in Kosovo were one factor in
Belgrade's decision to throw in the towel. B-52s had
flown 270 sorties and dropped 11,000 bombs.
After 50 years and hundreds of thousands of sorties,
B-52 crews have lots of tales to tell, some hair-raising
(landings with four engines out on one side, for example).
No matter what the subject, however, the story is always
filled with affection for an airplane that just keeps
going on, year after year, decade after decade, always
taking on new tasks, and always on the first team.
When a BUFF Went Down
The story of Linebacker II has
been told many times, but the cold statistics
conceal the human drama faced by every bomber
crew on every mission. Lt. Col. George Larson
provided the following excerpt of an interview
with Maj. John Wise, 28th Bomb Wing, to give
some insight into just how demanding these
missions were and how harrowing they could
be. All six crew members of Ash 02 survived.
"I flew my 295th combat
mission on Dec. 27, 1972. We were to attack
the Van Dien Supply Area. We were Ash Cell.
I flew Ash 02, aircraft No. 56-05999, not a
good position to be in, because the North Vietnamese
were using the lead aircraft to set up on the
following cell's aircraft.
"At the IP [Initial Point],
I believe there were five to six SA-2s fired
at us. At bombs away, we were level for dropping
our bombs, which were salvoed in 1.5 seconds.
I put the B-52D into a 90-degree wingover when--wham!--we
were hit in the left side [wing]. All four
engines on that side were finished. There were
lights blinking all over the cockpit. We were
later told by USAF intelligence that the fatal
hit was from SAM Site VN 549.
"All the crew was OK. We
had no engine power on the left side. It was
250 miles to reach friendly territory. Aircraft
control was terrible, trying to make course
on an exit heading to U Tapao. We were at 30,000
feet, and as the aircraft slowed, I would dive
down, picking up speed, slowly climbing, but
not making up all lost altitude. I could only
steer a course of 190 degrees, but we were
getting out of the North by using this roller
coaster maneuver. However, we were slowly losing
precious altitude.
"We crossed the 15,000-foot-altitude
bailout decision point, but I looked down and
there were lights. These lights were coming
from a firefight below between Communist troops
and US backed forces in Laos. I decided we
would not jump into the middle of a war. We
crossed the Mekong River at 12,000 feet, all
the time keeping in constant communications
with the Air Force rescue helicopters then
airborne.
"We had been in the air
nearly 45 minutes after being hit by the SAM
and it was time to bail out. I called the gunner
to go first. However, unknown to me at the
time, the gunner did not go out on the first
try, requiring a second attempt. The gunner
eventually went. The navigator attempted to
go, trying to blow the hatch below, but it
did not open, probably jammed from the SAM
hit in the left wing. The radar navigator ejected.
I told the navigator to jump out the open radar
navigator's hatch. The EWO then ejected.
"Well, the navigator's microphone
pulled loose as he jumped and I did not know
he had gone. I told the copilot to eject and-boom-he
was gone, filling the cockpit with insulation.
I kept calling the navigator. I was not going
to eject until I knew he had gone safely out
of the wounded bomber.
"At 3,000 feet, I heard
the Air Force rescue boys indicate that it
was time for me to get out of the aircraft.
Well-boom-the hatch above me was gone and then
I squeezed the ejection handle. Then, up and
out I went. I was uncertain if I would separate
from the seat. However, once in the wind, the
seat was gone and I was floating free. The
chute opened with a jerk. I looked down to
see the bomber hit the ground with a huge fireball,
turning night into day." |
