In October, the Pentagon selected Lockheed
Martin to build the Joint Strike Fighter, embarking
on a 25-year effort to replace the bulk of the US fighter
fleet with stealth aircraft. The announcement capped
a fierce, five-year technology contest and flyoff between
Lockheed and Boeing, settled the long-debated future
course of US tactical aviation, and confronted Congress
with serious questions about the health of the defense
industrial base.
Secretary of the Air Force James G. Roche, the official
in charge of selecting the JSF winner, said at a press
conference to announce the choice that Lockheed Martin's
proposed aircraft and development program clearly offered "the
best value for the government" across a range
of competitive categories. These included technical
merit of the design and flight testing of the X-35
concept demonstrator, as well as past performance of
the contractor and predicted cost of the system over
its lifetime.
The United States Navy and the air and naval services
of the United Kingdom-partners on the project-said
they concurred with Roche's pick.
The JSF will replace the F-16 and A-10 fighter and
attack aircraft in the Air Force, early model F/A-18s
in the Navy, and aging AV-8B Short Takeoff and Vertical
Landing fighters in the Marine Corps. Specially configured
but highly similar variants of the JSF will be built
for each of those services.
The government promptly signed contracts-one worth
about $19 billion for Lockheed Martin and teammates
Northrop Grumman and BAE Systems and one for more than
$4 billion to Pratt & Whitney, which will develop
the aircraft's F135 engine. These initial contracts
cover about 10 years of development and flight testing
and will pay for 22 aircraft--14 flyable airplanes,
seven ground-test items, and one stealth "pole
model" test airframe. Before the development phase
ends, however, the Pentagon likely will award more
contracts covering 465 initial production aircraft.
First Flight 2006
The first flight of the Air Force version is slated
for early 2006, and initial operational capability
is planned for USAF and the Marine Corps in 2010. The
Navy and Britain's Royal Air Force and Royal Navy will
have their first squadrons in 2012.
The JSF will be an enormous defense program. Plans
call for Lockheed Martin to build about 3,000 fighter
aircraft for the US and UK over 28 years or more. The
work will make Lockheed Martin, near the end of this
decade, the exclusive supplier of manned fighters to
the nation's military forces.
In addition, the JSF builder will be well-positioned
to dominate the overseas fighter market, where experts
see potential for sales of another 3,000 airplanes
to foreign forces. Along with the prize of building
the actual jets goes a training and support package,
including simulators, as well as the inside track on
upgrades and modifications.
Pete Aldridge, DOD's acquisition chief, noted that
the value of the fighter contract ultimately "could
be in excess of $200 billion" and acknowledged
that it is the largest US military program ever.
Work on the 126-month development phase of the project
began immediately.
"The train has left the station," said
JSF program director Air Force Brig. Gen. John L. Hudson.
Pieces of the aircraft will be made at numerous team
locations, but final assembly will be performed in
Fort Worth, Tex., on the same mile-long assembly line
that churned out thousands of F-16s.
Only a few months ago, there was no certainty there
would even be a JSF program. The Bush Administration,
in the midst of a months-long review of national military
strategy, made it known it was considering scrapping
one of three new fighters on the Pentagon's books:
the JSF, USAF's F-22 Raptor, or the Navy's F/A-18E/F
Super Hornet. The JSF was considered the most vulnerable
because, unlike the other two aircraft, it was not
yet in production and therefore had a limited political
constituency in terms of jobs and suppliers.
However, in announcing the decision to press ahead
with the JSF program, Aldridge acknowledged that the
fighter fleets of the Air Force, Navy, and Marine Corps
are rapidly aging. The Pentagon's Joint Requirements
Oversight Council had reaffirmed the urgent need for
the JSF to replace its wearing-out inventory of fighters,
many of which are already near or at the end of their
planned service lives.
Aldridge chairs the Defense Acquisition Board, which
just prior to the contract go-ahead, decided that the
JSF is in fact a necessary program, the technology
is mature enough to proceed into development, and the
project is affordable within expected Pentagon budgets.
This blessing allowed the contracts to be signed and
also gave assurance that the program would not be reduced
in scope, at least not in the near future.
Close Scrutiny
Affordability was "one of the questions that
we looked at very carefully," Aldridge said. He
noted that tactical aviation has averaged about an
18 percent share of the Pentagon's budget over the
last 20 years, getting as high as 25 percent during
the mid-1980s. In the coming decade, all tactical aviation
procurement--not just the JSF--will stay under that
average until Fiscal 2007. Even after that, "the
peak of the spending for Tacair will not reach but
22 percent of the DOD budget, less than what we did
in the mid-'80s," Aldridge said.
The same Pentagon panel had, less than two months
before, given a green light to proceed with production
of the F-22, which will replace the F-15C in the air
superiority mission.
Three versions of the JSF will be built, and all will
be stealthy.
The Air Force model--plans call for building 1,763
of them for the service--will be the least expensive
of the three. It is expected to cost about $40 million
a copy in 2001 dollars. It will replace the F-16 and
have similar or better aerodynamic performance--a top
speed of about Mach 1.8 and able to turn at nine Gs--as
well as a combat radius of 690 miles. Internally, it
will carry two 2,000-pound bombs. After enemy air defenses
have been beaten down and stealth is less important,
the Air Force JSF will also be able to carry external
stores and fuel tanks, as well as missiles on wingtip
launchers, all of which greatly diminish the low observability
qualities of an aircraft.
The JSF used by the Air Force and Marines will be
slightly larger than the F-16, with wingspan four feet
wider but length only one foot longer. The fuselage,
however, will be far deeper, to hold munitions and
fuel internally. Whereas the F-16 needs to carry bulky
and heavy targeting and vision pods, the JSF will be
externally "clean," and all optics will be
accommodated through a faceted aperture under the nose.
The airplane will also have basic flight displays
on the inside of the helmet visor, helmet-mounted cuing
of weapons, and respond to certain voice commands.
USAF plans to use the JSF in much the same way as
it now employs the F-16. It will principally be an
attack aircraft but with sufficient aerodynamic agility
to win dogfights with almost any other aircraft. Because
of its stealth and nimbleness, said Aldridge, the JSF
will "provide an air-to-air capability second
only to the F-22 air superiority fighter." He
has said previously that, at half the price of rival
foreign fighters and twice the capability, the JSF
could doom foreign fighter makers.
Combat Persistence
Gen. John P. Jumper, Air Force Chief of Staff, said
the JSF will provide persistence over the battlefield
in future combat operations because it will be numerous
enough to strike in many places simultaneously and
stealthy enough to survive against emerging air defense
threats.
Because the Air Force JSF won't arrive for another
decade, USAF will have to invest several billion dollars
in a systems and structural upgrade of the F-16 fleet,
which will start to reach retirement age in large numbers
beginning in 2005.
Jumper has said he expects some of the JSF buy will
go to Air National Guard units as well as for active
squadrons, to keep the Total Force balanced in its
equipment.
The Navy model will be capable of landing on an aircraft
carrier. To achieve that, it will have larger and heavier
landing gear, more structural strength, an arresting
hook, and larger wings for better range and carrier
landing characteristics. The Navy plans to build 480
JSFs, at a 2001 unit cost of about $50 million. It
will be about the size of the C model of the F/A-18.
The USMC version will have Short Takeoff and Vertical
Landing capability and will be the first operational
STOVL aircraft that will also be capable of achieving
supersonic speeds. The Marines plan to deploy their
JSFs at unimproved forward airstrips and on amphibious
assault ships to be near the action when close air
support is needed for ground troops. A total of 609
STOVL versions of JSF are planned for the Marine Corps,
which will pay about $45 million apiece for them in
current dollars. They will have a combat radius of
about 500 miles, the cost of having the capability
to take off and land vertically.
The UK will decide within two years whether it wants
to procure the carrier version or STOVL model of the
JSF. The choice will be made after Britain makes a
more basic decision about the style and design of the
next generation of British aircraft carriers. In any
event, the British requirement is for 150 airplanes.
The UK has been a partner in the JSF since the inception
of the program in 1996. In exchange for about $2 billion
in contributions to the project, the UK was able to
have input into the aircraft's performance requirements
and basic design. It will also receive its aircraft
concurrently with the US.
Six other nations are likely to join in the development
phase. They are Canada, Denmark, Italy, Netherlands,
Norway, and Turkey. Those that participate will pay
a share of development costs. In return, they will
receive some share of the development work and move
to the front of the line for foreign sales of the aircraft.
About 35 nations operate the F-16, F/A-18, or AV-8B,
and all would be considered candidates to purchase
the JSF at some point in the future. Pentagon and industry
officials say the biggest issue in export would be
the level of stealth the US would be willing to release
to a customer, as well as the degree of sensor fusion
and access to US combat information systems.
Congressional Unease
The JSF has always been structured as a winner-take-all
contract; whoever emerged with the winning design would
build all 3,000 airplanes planned. The scheme has been
questioned numerous times by members of Congress who
are reluctant to concentrate all fighter work with
a single contractor facing no competition.
Jerry Daniels, president and chief executive officer
of Boeing Military Aircraft and Missile Systems, acknowledged
at a press conference to discuss why the company lost
in its bid for the JSF work, that "the danger
of winner-take-all ... is that one company--clearly
now, that is Boeing--could get out of the fighter business." However,
he noted, such an event "isn't going to happen
tomorrow."
At least through the end of this decade, Boeing will
continue to build the F/A-18E/F Super Hornet, and it
is a major subcontractor to Lockheed on the F-22, production
of which is scheduled to run through 2012. Moreover,
Boeing stands a good chance of selling F-15Es to South
Korea, so Boeing will likely be producing fighter airplanes
for at least another 10 years.
However, the "perishable commodity" is
the knowledge of engineers who are skilled in designing
fighters, who know "how to take metal and composite
materials and glue and put it into something that weighs
30,000 pounds but you can't find it with a radar," Daniels
observed. This capability, which he called "a
national asset," will dissipate without "meaningful
work" to do in fighter design.
The Pentagon has reviewed the winner-take-all approach
at Congress' insistence-three times in 2000 alone,
Aldridge noted--and still found the approach to be
the most cost-effective. Various Pentagon and independent
analyses estimated that setting up a second production
line for JSF could cost between $1 billion and $4 billion,
depending on how much production capability is duplicated.
Aldridge noted Boeing's ongoing work on the F-22 and
Super Hornet and also pointed out "there's still
design work going on [with] unmanned aircraft and unmanned
combat aircraft." Boeing's design teams would
be "appropriate" to work on these, he said.
Furthermore, DOD has put into the Fiscal 2002 budget
some money to begin work on "a new long-range
strike platform that could have capabilities far out
into the future," Aldridge said.
In the case of prime contractors, "there's plenty
of work," he concluded. He added that Unmanned
Combat Air Vehicles and other unmanned systems hold
much promise. "When you get to the period of 2025
or 2040," said Aldridge, "it's not clear
that manned aircraft competition will exist at all," possibly
rendering the question of preserving more than one
manufacturer moot. In fact, some industry and Pentagon
officials have speculated that if Boeing's defense-suppression
UCAV performs well, more of them could be purchased
at the expense of some cuts to the JSF buy.
Daniels admitted that UCAVs offer a distinct opportunity
for Boeing but that the long-range strike platform
will not enter a design phase until near the end of
this decade, too far out to help cushion the loss of
the JSF program.
Man From Missouri
The Missouri and Washington Congressional delegations-representing
the largest concentrations of Boeing workers-introduced
legislation that would order the Pentagon to give some
JSF work to Boeing as an industrial base-saving measure.
Missouri Republican Sen. Christopher Bond has called
a second production line a national "insurance
policy."
Aldridge, however, said that the two teams knew going
into the competition that the result would be a winner-take-all,
and they structured their teams and assigned work share
and risk within them on that basis.
"If Lockheed Martin wishes to use the unique
talents of Boeing ... they are free to do so," Aldridge
said. "We're not forcing them to do it." He
later acknowledged it would be "politically astute" of
Lockheed Martin to find some work for Boeing on the
project. For its part, Lockheed Martin said it would
entertain assigning a work share to Boeing if the government
asked the company to do so. However, a Lockheed official
noted that, with 18 percent of work share already assigned
to Northrop Grumman and 12 percent to BAE Systems, "there's
not a lot of room to play around with this."
The Pentagon would oppose any legislation mandating
a share to Boeing, Aldridge said. In a letter to concerned
members of Congress, he noted that the winner-take-all
approach was validated as the most efficient way to
conduct the program and that creating additional assembly
lines or redundant manufacturing capabilities would
add to the cost and delay the project. He emphasized
that there will be a rigorous engine competition on
the program and that the Pentagon is also seeking ways
to expand competition on the radar and other critical
avionics.
Boeing is also considered likely to get substantial
Air Force orders for 767 widebody transports to serve
as tankers and replacement airframes for the E-8 Joint
STARS, RC-135 Rivet Joint, and possibly the E-3 AWACS
fleets. Roche has suggested leasing the airplanes as
a means of speeding up their acquisition, saying the
airframes were urgently needed "yesterday."
F135 engines for the JSF will be made initially by
Pratt & Whitney, but General Electric-Rolls Royce
will produce a competing power plant called the F136.
The two engines will have to be functionally identical
in the way they mount on the airplane, in the procedures
for their maintenance, and in the software that runs
them, so as to reduce engine-unique spare parts and
processes.
"We want it so that you can take out a Pratt
engine and put in a GE engine, and the pilot will never
know the difference," Hudson said. Pratt & GE
will compete for JSF engine production in lots, in
an arrangement akin to the "great engine war" of
the 1980s between the F100 and F110 power plants.
No Rush
In the run-up to the Quadrennial Defense Review, several
area study teams noted that the Navy is still without
a stealth airplane and, under the JSF schedule, will
not get one for another decade. Several panels suggested
the JSF be accelerated, for at least the Navy version.
Aldridge said that "we'd love to have this airplane
today" but the Pentagon will not rush the program.
"We're going to make sure we do it right," he
explained, adding that the JSF will follow a "spiral
development" plan in which early models will not
have "100 percent" of the ultimate capability
planned for the type. The JSFs will be improved in
block upgrades, and early models will be retrofitted
as more advanced avionics, software, and weapons become
available.
Hudson, too, acknowledged that the development program
has been laid out in a well-paced, "logical" fashion
and that tinkering with it would likely not produce
airplanes much faster but would certainly raise the
cost "and the levels of risk that we associate
with this program."
Prior to the JSF go-ahead, the General Accounting
Office advised Congress to slow the program, arguing
that, while good progress had been made in reducing
technological risk, the program was still not a "low
risk" venture. The GAO warned that cost overruns
and schedule delays could loom in the future if certain
of the program's business, manufacturing, and weapons
initiatives don't pan out. The Pentagon rejected the
assertion and insisted that the risks in JSF are well-understood
and well within reason.
Lockheed Martin was the "clear winner" of
the competition, Roche said, adding that the outcome
was not "a squeaker" but also not a shutout,
either.
"It became clear, as we went through this process,
that the case built more and more strongly" for
the airplane that will derive from the X-35 demonstrator,
Roche added.
Lockheed Martin JSF leader Tom Burbage said "our
biggest gamble" was the lift system in the STOVL
version. This machine uses a swivel-down rear exhaust,
coupled by a shaft to a vertically mounted "lift
fan" behind the cockpit. The two posts of thrust-one
of which is cool "fan" air and not engine
exhaust-made for a cooler environment around the airplane,
as well as more lifting power at lower engine power
levels.
The swiveling rear exhaust is a licensed design from
the Yakovlev design bureau in Russia, which tried it
out on the Yak-141 STOVL fighter.
"It was all or nothing," Burbage said. "If
the propulsion concept didn't work, we obviously weren't
going to be competitive."
Daniels, the Boeing executive, said the lift fan concept
was "probably the single most important feature" of
the competition.
Advantage: Lift Fan
Boeing's proposal called for "direct lift," meaning
the engine was providing all the raw power to raise
the airplane. This meant it had to run hotter, which
probably cost Boeing points in life-cycle costs; the
Boeing proposal would have burned up engines more quickly,
Daniels allowed. The Lockheed Martin proposal also
provided more lifting power, despite the added weight
of the lift fan, 60 percent more than with the engine
alone.
"We had thin margins on some parameters, where
Lockheed had very strong margins on those same parameters," Daniels
said. As requirements to carry more ordnance were added,
Boeing's margin shrank.
"We're basically using an engine where we're
diverting the thrust to get us direct lift," Daniels
said in a press conference. "With the fan system,
they've effectively created what is like another engine
in the aircraft. So they're getting much more efficiency."
"In the non-STOVL versions, the lift fan is replaced
by a fuel tank."
The Pentagon told Boeing that the company had scored
slightly better on prior performance and management
but had not scored as well as Lockheed on airplane
capabilities, Daniels reported. Aircraft unit costs
were about the same, he added.
Burbage said the "challenge now is to make sure
we've got the life-cycle cost dimension" under
control. Although most of the technologies going into
the JSF were tested either in the factory or on the
X-plane demonstrators, long-term reliability and maintainability
haven't been proven "because these were very abbreviated
flight [test] programs," he said.
Former JSF program director Marine Corps Maj. Gen.
Michael A. Hough said the two JSF concept demonstrators--Lockheed's
was the X-35 and Boeing's the X-32--turned in phenomenal
performances and rarely missed a flight-test hop because
of system glitches and missed none due to engine failure.
To achieve such a thing with experimental aircraft
was "unprecedented," Hough said, and validated
the new computer-aided design systems employed in their
construction.
Lockheed used two aircraft to demonstrate the capabilities
of all three versions. The Air Force model was designated
the X-35A and flew more than 27 hours on 27 flights
in just 30 days. The same airplane, redesignated X-35B,
was the STOVL model with the lift fan installed; it
flew 21.5 hours over 39 flights in 45 days. The X-35C
was the carrier version, which had heavier landing
gear and Navy-specific equipment and wings. It racked
up 58 hours over 73 flights in 85 days. The flight
test schedule was "aggressive," Burbage noted.
There is no plan to use the demonstrators for any
further testing. Hudson said there would be a certain
amount of risk in doing so, since they were designed
for a brief round of use and not extended flying. Moreover,
although the X-35 strongly resembles the proposed airplane-which
may be called the F-35 or F-24--it was not a prototype.
Hudson has had "lots of requests" from museums
around the world for the demonstrator aircraft.
Burbage said Lockheed will achieve a maximum production
rate on the JSF at approximately 17 a month in 2011.
The Fort Worth plant built F-16s at a "considerably
higher" rate during the late 1980s, but the JSF
figure does not count foreign sales. Burbage said the
facility can accommodate more than 17 per month but
declined to give a figure.
Born in Crisis
The JSF program grew out of a defense financial crisis
in the early 1990s. USAF needed a cheap, lightweight
fighter to replace the F-16, the Navy wanted a stealthy
medium bomber, and the Marines wanted a new jump jet
to replace the AV-8B Harrier. As a cost-saving measure,
the three programs were merged, to the catcalls of
both those in the military and industry. It was considered
almost impossible to build an airplane that could satisfy
such divergent requirements without being a jack of
all trades, master of none.
Burbage said he himself had doubts it could be done.
"Back in those days, I'm not sure we had the
tools to do it," he said. "Even as recently
as three or four years ago, ... the industry really
didn't have the capacity to design a family of airplanes
where no user paid any penalty for what the other guy
needed."
However, "today, with our 3-D, solid engineering
modeling tools, and just the pure processing power
of the computers, you can in fact create these collaborative
engineering environments," in which the talents
of geographically dispersed companies can work together
on a design, create templates, and wind up with parts
that mate perfectly, Burbage said.
He also said the services demonstrated great discipline
in holding their requirements to those that were absolutely
needed. That made the joint solution possible.
"Once the airplane gets off the ground and raises
the landing gear, they all do the same thing," said
Burbage. "They're all multirole combat aircraft.
... The challenge really is to ... accommodate all
the different basing requirements without penalizing
one guy for the other."
