Three or four times a day, the sleek, sinister-looking
B-2s roar out of their hangars, glide along a taxiway
to the airstrip, push forward, and then seemingly levitate
into the Missouri sky. They hook up with tankers, practice
aerial refueling, cross a few states, carry out a practice
bomb run, do some low-level hill dodging, and return.
It's almost routine, but no one expected it to be
that way--not at this point.
The hundreds of Air Force people who fly, maintain,
and support the B-2s at Whiteman AFB, Mo., are "writing
the book" on the new bomber, and it is now clear
that they have raced a few chapters ahead of schedule.
They are quickly filling in the gaps of knowledge about
the true capabilities of this aircraft, a huge wing
with windows and wheels, crammed with dozens of new
technologies.
"We're taking some pretty big steps right now," reported
Brig. Gen. (Maj. Gen. selectee) Ronald C. Marcotte,
commander of the 509th Bomb Wing and the man who has
shepherded the B-2 program at Whiteman since before
the first stealth bomber arrived in December 1993.
The "steps" mark the location of the B-2
on a continuum of crawl, walk, run--a strategy the
people of the 509th scrupulously follow.
When General Marcotte was organizing the unit for
the B-2's arrival, he asked those experienced with
bringing new airplanes on-line what he could expect.
The experts, noting that the B-2 is still considered
to be in development, cautioned him not to try to do
too much too fast, the General said. Though the B-2
had been wrung out in flight test, its novel technologies
might still provide some unpleasant surprises in initial
service. Extreme caution was called for.
National Treasure
"You don't have to think very hard to realize
this is a lot of national treasure we're talking about," General
Marcotte said. The unit flyaway cost of each bomber
is a breath-catching $600 million, and in addition "there
are all the people and the facilities put into it."
Air Force officials knew that critics of the B-2 would
be watching keenly for any error that would suggest
the new bomber was unreliable, a technological failure,
or unsafe. The months before the B-2 arrived were spent
trying to figure out how to bring it to operational
status "in a fashion that you don't make mistakes
that could, basically, end it all," General Marcotte
said.
The General was told that the B-2s would likely fly "maybe
once or twice a quarter" in the initial phase
of deployment, given USAF's experience with other large,
complex flying machines and considering the many unproven
technologies rolled up in the new bomber. He likened
the first operational sortie, carried out less than
a week after the first B-2 arrived at Whiteman, to "a
shuttle launch . . . with cameras rolling and hundreds
of personnel" attending to every detail.
Now, the launch of an airplane takes place "with
one supervisor out there," and the sorties amass
at up to thirty a week. Two years ago, such a rate
would have been wishful thinking, but the B-2 is "exceeding
any expectations," said General Marcotte. He added, "I
expected more 'unknown unknowns,' " and he was
prepared for "one step forward, one step back,
. . . but we haven't had that."
The B-2 went to its first Red Flag exercise last summer, "a
year ahead of schedule," General Marcotte noted.
It made an appearance at the Paris Air Show last June
and at the Singapore Air Show in February by way of
Guam. A second, more challenging Red Flag role was
planned for early this year. In early summer, the 509th
will receive a new, improved model of the B-2--the
first Block 20 airplane.
General Marcotte said that the Air Force is "on
track" in its plans for the B-2 squadron to become
an operational unit of US Strategic Command in March
1997. In that month, it will take its place alongside
the B-52 in the bomber leg of the strategic nuclear
triad, the General said.
"We're doing very well," he asserted. "We're
pushing forward in a safe and productive fashion."
General Marcotte said he has hammered on the message
of caution to his people because most of them have "succeeded
their entire career by . . . being aggressive." Now,
the same individuals must blend this attribute with
caution.
To be part of the initial cadre assigned to the B-2,
pilots went through a rigorous selection process. An
individual's record had to be spotless, without the
slightest safety infraction. Each candidate needed
the recommendation of his wing commander, other endorsements,
and thousands of hours of flight time. Many of the
first pilots have combat experience, and all have demonstrated
an ability to learn and progress quickly. Maturity
was an important factor, and they had to pass muster
in personal interviews not only with General Marcotte
but also with Gen. John Michael Loh, former commander
of Air Combat Command.
Mature Pilot Force
"We have a very mature pilot force," said
Col. Gregory H. Power, 509th Operations Group commander. "My
youngest pilot is a midlevel captain," he noted.
The pilots' experience comes mostly from flying in
bomber units, but there are veterans of various fighter
aircraft as well. B-2 pilot training, once administered
by flight-test and contractor pilots, now is carried
out by USAF instructor pilots at Whiteman.
"The training program is about six months [long],
which is typical of bombers," reported Col. James
F. Whitney, Jr., chief of the 509th Formal Training
Unit.
Besides flying the airplane and establishing the rules
by which it flies--covering everything from takeoff
weather minimums to weapons release procedures--pilots
are also heavily involved in developing tactics for
the airplane, exploring what it can do operationally
in order to derive the maximum effect from its unprecedented
range, payload, and stealth.
"It's a free-for-all," said Capt. John S.
Paganoni, a B-2 pilot. "With all this combined
expertise from all over, there's no predisposed thought
and no inertia" requiring that things be done
in a traditional way. "We have a lot of guys here
who were in the war" in the Persian Gulf in 1991,
and their combat experience is proving highly valuable
in developing "the best way to employ the airplane," he
said.
Captain Paganoni added that the B-2 pilots are considered
the experts on their still-new airplane and are invited
to think tanks and conferences where tactics and strategy
for the entire Air Force are developed. "We have
a direct impact," he said.
There is a mix of ranks in the B-2 pilot cadre, and
it is intentional, the result of a lesson learned in
the B-1 program. The pilots bringing that system into
service all had about the same experience level and
about the same number of years of service. It was a
situation that led to staffing bottlenecks and difficulty
turning officers loose for professional military education.
Every B-2 pilot can count on flying about one sortie
per week. Each flight is preceded by a day of mission
planning and a full dress rehearsal in the Weapon System
Trainer. This full-motion simulator is "ninety-five
to ninety-eight percent like the real aircraft," said
Col. Jonathan George, commander of the 393d Bomb Squadron. "It
really is outstanding fidelity."
Colonel George asserted that the simulator gives a "very
accurate" feel for the way the B-2 handles. Another
instructor, Maj. Steven M. Tippets, said its state-of-the-art
graphics system accurately depicts the countryside
surrounding Whiteman for "almost 200 miles in
every direction, just about down to every tree."
Because the 509th has a small number of operational
aircraft, the wing "relies more heavily on simulators
than other flying units," said Colonel Whitney.
However, he does not believe that the 509th will use
more and more simulator time as a substitute for real
flying time.
Lots of Stress
"To make a good pilot," said Colonel Whitney, "you
have to handle inordinate amounts of stress. A pilot
knows he's not going to get hurt in a simulator."
Mission planning entails plotting radar threats the
B-2 would face on a given run and determining how best
to avoid or defeat them with the B-2's stealth capabilities.
It's a process that can take "one day, plus" to
complete, said B-2 pilot Capt. Scott Hughes.
B-2 crews fly to bomb ranges in Utah, Wisconsin, and
Kansas in order to perform practice runs within the
US; they go to other sites when required to do so by
the particular exercise or the specific mission to
be rehearsed. About one in every five sorties entails
the release of a live bomb, inert bomb, or smoke bomb.
During the flight, a weapon release can be fully simulated,
with nothing actually being dropped.
All flights involve practice in aerial refueling.
The B-2 has a considerable bow wave that can make tanker
rendezvous "kind of tricky," Major Tippets
said.
Low-level flying is usually part of a four-hour training
sortie. Though the B-2 is designed to be stealthy at
medium and high altitudes, and may not need to make
ground-hugging flights, the pilots practice the skill
because under some circumstances it might be required.
"There are some advantages to going low," Captain
Hughes said, "and, if you don't train to do it,
you lose the ability to do it."
General Marcotte noted that the B-2's flight profiles
will be "totally target-dependent" and crews "have
to be able to do it all."
To get the most out of what is an exhaustive preflight
inspection, two training sorties are flown back-to-back
to save time. When one crew lands, the engines are
kept turning while a second crew climbs aboard.
The operational concept forming up for the B-2 generally
goes like this: The Air Force would send the B-2 as
a single ship against a "high-value target set" well
within an enemy's air defense net. The bomber would
be equipped and flown in a way that would permit it
to hit multiple aimpoints in a single pass with great
accuracy.
Soon the B-2 will have capability for employing a
near-precision weapon guided by signals from the Global
Positioning System satellite constellation, the GPS-Aided
Targeting System/GPS-Aided Munition (GATS/GAM). Later,
it will have the Joint Direct Attack Munition. Both
weapons will be able to hit a target through bad weather,
relying on cues from GPS satellites and aimpoints designated
by the mission commander on the photographic-quality
synthetic aperture radar. Unlike precision weapons
of the Gulf War, it will not be necessary for the mission
commander to manually hold an aimpoint for the bomb.
Triple Threat
One B-2 pilot, Maj. Gregory A. Biscone, asserted that
the B-2 enjoys "all the advantages of an F-15E
in terms of precision, with all the advantages of the
B-52 in load, coupled with the advantages of the F-117
in stealth."
The B-2 can land at "twice as many fields" as
the B-1 can, General Marcotte said, meaning the aircraft
can be deployed just about anywhere, worldwide. Deployment
kits are being developed now, and within a year the
Air Force should have enough to permit three to eight
aircraft to fly a mission to an expeditionary airfield.
In a major regional conflict, the B-2s may well fly
and fight directly from Whiteman, requiring missions
lasting more than twenty-four hours. The airplane's
part in last year's Red Flag exercise was "planned
and run all from Whiteman," said Colonel Power.
The pilots are unconcerned about sustaining such a
seemingly exhausting flying schedule. Unlike the B-52,
which can carry additional crew, the B-2 can carry
only two pilots. The B-2 bomber is highly automated,
and the pilots believe it is safe for one of the crew
members to take a nap while the other flies the airplane.
"For the initial round [of combat], adrenaline
alone will keep you going," Major Biscone said,
and for continuing missions, "we may do go/no-go
pills" relied on by some combat crews during the
Gulf War.
However, he added, "crew ratio is the only thing
that will sustain long sortie durations." So far,
USAF has no plan to put a third crew member on the
B-2, although there is room and an escape hatch exists
for a third ejection seat. General Marcotte said that "for
training purposes only, it would be nice to have a
third seat in the B-2," but he would not put this
near the top of a wish list for improvements to the
airplane.
The General said he is pleased that, with videoconferencing,
he has the ability to get the System Program Office,
the test center, the contractor, and the operations
room all talking to each other at a moment's notice,
such as for an in-flight emergency.
Captain Paganoni noted that the B-2 does offer two
amenities helpful in reducing crew fatigue on a long
mission--the means to prepare a hot meal and a flush
toilet.
Staying Sharp
To supplement their B-2 time, the pilots also fly
the T-38 Talon, which helps build their flight experience
and keep their airmanship edge, said Maj. William R. "Buzz" Barrett. "The
B-2 and the T-38 fly very differently," he said,
with the B-2 being "much easier to fly."
While the B-2 is highly automated and will cruise
with minimal effort, the T-38 "does 300 knots
in the pattern. There's a lot of cross-check, . . .
a lot of airmanship decisions. The B-2 requires more
systems knowledge, but the T-38 keeps your pilot skills
sharp," he said.
In a time of budget stringency, only B-2, U-2, and
F-117 units have access to T-38s as companion trainers.
After a B-2 mission, an extensive debrief takes place.
In the room are the flight crew, contractor representatives,
maintenance specialists, and people from the B-2 Combined
Test Force at Edwards AFB, Calif. Gripes are detailed,
and lessons learned are submitted on Air Force Form
847. These, in turn, build the B-2 Dash One manual,
which describes better-flying tips as well as a host
of "do nots" that could lead to damage or
destruction of the aircraft.
The initial cadre of maintenance personnel on the
B-2 was handpicked, but shortly after the B-2 came
to Whiteman it became a specialty available for any
enlisted person with good enough marks. There are one-
and two-stripe airmen working on the airplane. They
get four to eight weeks of specialized training for
it, and the aircraft has proven docile in their hands.
"You can do ninety percent of the maintenance
on the B-2 without removing any panels," according
to 2d Lt. Jeffrey M. Burnside, of the 393d Bomb Squadron. "There
was a great deal of thought put into maintenance when
they were designing this aircraft."
As to its reliability, Lieutenant Burnside said the
B-2 is a champ. "You don't have people sitting
around with nothing to do," he said, "but
they aren't here all night fixing things, either."
Propulsion Specialist SrA. Michael P. Sullivan observed
that the B-2's F118 turbofans are similar to others
he has worked on, though "a little harder to get
to" because they are buried in the fuselage to
hide their fan blades from radar. He has "no big
gripes" with the engines.
Flight controls are critical to the highly unstable
B-2, which operates by a quad-redundant, fly-by-wire
system, but they "work great," said SrA.
Robert G. Rayburn, who specializes in them. "I
haven't seen any problem areas."
Each B-2 has its own "dock," a term the
crews prefer over "hangar" because the airplane
is positioned carefully to hook up with umbilicals
in the floor. Each dock is immaculate, with none of
the hydraulic fluid or fuel puddles or stains one would
find under any other large airplane.
"Used to be, if an airplane didn't leak, it meant
there wasn't any fuel in it," Lieutenant Burnside
said, but the B-2 is a departure from most large aircraft.
"The tolerances are very tight" between
panels on the aircraft, Airman Sullivan said. "They
have to be; leaks can damage the LO," or low-observable--stealth--characteristics
of the surface.
Tolerances are so tight that the B-2, even with a
wingspan comparable to that of the B-52 (the wings
of which can flex up to eighteen feet in flight), remains
highly rigid. Its wings flex less than three feet,
and as a result nothing drips.
"We don't have hydraulic problems or electrical
problems, only one fuel [incident], and no leaks," Colonel
Power noted. He also said that, to date, no B-2 crew
has had to shut down an engine in flight.
"You just don't lose sorties on this airplane," said
Major Biscone, a veteran of many aborts with his previous
ship, the B-52. "If you're scheduled to go, you
go."
The Blackout
Only one really serious in-flight emergency has occurred;
on that occasion, all the displays in one B-2's glass
cockpit went blank. The airplane landed without further
incident.
The specialized work pertaining to the B-2's stealth
characteristics is conducted in a windowless, keypad-entry
hangar across from the flight line. There, experts
maintain the advanced materials and gear that reduce
the B-2's radar cross section--special tape that shields
panel joints, heat-absorbent tiles in the exhaust area,
and structures made of epoxy resins and other exotic
materials.
"Tape is tape," observed Capt. Casey W.
Hughson, who supervises LO maintenance in the 509th
Maintenance Squadron. "Fly it around long enough
at high speed and it will start to peel back." The
tape must be carefully reapplied using special adhesives,
and it must rest on the airplane just so, lest it disturb
the surface contours. A barely noticeable disruption
of the surface contour can increase the airplane's
radar cross section considerably.
"What these guys do isn't a science; it's an
art," Captain Hughson said. "For example,
getting the paint on exactly one mil thick--that's
an art."
The LO shop is also the first line of repair for the
B-2. There have been no catastrophic problems, but
there have been some challenges. A birdstrike several
months ago hit a bull's-eye on a B-2 control surface.
Though the Whiteman team initially thought the part
would have to go back to the factory, it was diagnosed
and repaired at the base.
The B-2 is not problem-free, however. The LO shop
spends most of its time maintaining the aft deck, part
of the exhaust covered with heat-absorbent tiles similar
to those on the space shuttle. The aft deck also experiences
lots of dynamic stress in flight. Cracks occur regularly.
"The aft deck is a known challenge," General
Marcotte said, "but we are repairing it mostly
ourselves."
Northrop Grumman has developed new procedures that "speed
up the process" to repair cracks, General Marcotte
noted. "What used to be months now is down to
a week or two weeks."
Weapons loaders have a rare advantage in the B-2 program.
They are able to practice on a weapons loading trainer
that is a close replica of the B-2's bomb bay and cockpit.
They practice the extremely precise process--down to
millimeter accuracy--of loading Mk. 84 bombs and nuclear "shapes" but
can also simulate malfunctions and emergencies that
might be hazardous if practiced with a real aircraft.
"It was purpose-built" for weapons loading
and "allows us to train loaders without sacrificing
an airplane from the flying lineup," Colonel Power
said. With only eight aircraft available, "that's
a tremendous help."
Different Kind of Stealth
The B-2's stealthiness is what sets it apart from
the other bombers in Air Combat Command, and it is
one of the big unknowns still being explored in the
program. Though the Air Force has operated a stealthy
airplane under combat conditions--the F-117 in Operation
Desert Storm--General Marcotte said that the B-2 "is
stealthy in a different way from the F-117" because
of the techniques and materials used.
Early this year, the first of a planned series of
tests was run to see how well the B-2's stealthiness
holds up in the field. The test is called the Periodic
RCS (Radar Cross Section) Surveillance Mission (PRSM),
and it determines whether field maintenance can keep
the B-2 at the specified, factory-installed levels
of radar observability.
The test findings are classified, but "we were
pleasantly surprised . . . and very happy with the
results," said Colonel Power. Technical orders
have been upgraded--"we need to do some fine-tuning." However,
said the Colonel, "we are applying the lessons
learned, and next time we'll see even better results."
The B-2 is being phased into service gradually. The
509th has been operating with the initial batch of
airplanes--Block 10 models--but has already returned
one to the factory, where it will be reconfigured into
a Block 30 version. As Whiteman gets Block 20s from
the assembly line, its Block 10s will be traded back
for refitting. When fully equipped with Block 20s,
the 509th will start trading them back for Block 30s,
which will have the full complement of capability planned
for the B-2, in both weaponry and stealth.
During this rolling conversion period--expected to
last another four years or so--the 509th will have
a stable complement of eight to nine B-2s at any given
time, so today's operating pace is likely to remain "fairly
stable" until the last eleven Block 30 airplanes
start arriving, Colonel Power said.
The 509th is now undergoing nuclear surety inspections,
involving tests of security, procedures, and facilities.
Colonel Power said the unit expects to receive certification
for nuclear weapons by January 1, 1997. Initial operational
capability will focus on the nuclear mission, but it
is clear that the Air Force would prefer to measure
the B-2 against full requirement and full capability,
which will come only with the arrival of the Block
30 airplane.
"Initial LO signature tests have confirmed the
stealthiness of the B-2 and provided confidence that
the final configuration will meet the user's needs," an
Air Staff spokeswoman said. "Initial tests on
the radar, navigation, and weapon-delivery systems
are complete, and we are working to deliver full functionality
and capability in our Block 30 configuration."
Flight testing of the B-2 airframe and of the weapons
in the Block 10 and Block 20 is complete, the Air Staff
reported. Block 30 testing is already under way and
should be finished next summer.
The Whiteman facilities built to support the B-2 were
designed and constructed bearing in mind that the B-2
has a very long life expectancy. "These buildings
will last a hundred years," Colonel Power said.
Each of the twenty currently planned B-2s will have
its own dock at Whiteman, but "the acreage is
here" to accommodate more if they are built, he
added.
General Marcotte was wrapping up his stewardship of
the B-2 early this year and counted it as the plum
job of his career. Looking ahead to emerging technologies
that may compete with the B-2, he said he cannot foresee "the
bomber losing its place in the near future."
The B-2 brings "a tremendous advantage" to
war planners because it "ensures the capability
to slow down an enemy," buying time for follow-on
forces, he continued. So far, incremental improvements
in engine and weapons technology for smaller aircraft
haven't come close to matching the B-2's ability to "get
a warning order and twenty hours later be dropping
bombs" precisely on target.
"We have to make our own people understand what
it brings to the fight."
