Wing problem delays new fighter * Super Hornet defies quick fix
By the Seattle Post-Intelligencer
Seattle -- One of the Boeing Co.'s most important military aircraft
programs may be in trouble.
A wing problem with the F-18 Super Hornet that causes the Navy's
newest strike fighter to lose lift during key maneuvers may be more
serious than first believed, according to a memo to Navy Secretary
John Dalton.
If the wing has to be redesigned, it would mean costly delays
and would give critics in Congress more ammunition to either kill
the Super Hornet outright or reduce funding for it.
"Any wing redesign would obviously be very serious and would
have implications on when the program would enter full-scale pro-
duction," said Bert Cooper, a Research Service analyst.
About 7,000 Boeing workers in St. Louis build the Super Hornet,
Harrier, F-15 and F-18 Hornet.
The Navy and Marine Corps want more than 700 of the $40 million
jets to replace aging F-18 Hornet. Ten Super Hornets have been built
so far. Three were used for ground tests; seven are undergoing flight
testing by Boeing and the Navy at the Patuxent River Naval Air
Station in Maryland.
Congress has so far approved low-rate production of 32 planes. If
funding is approved, full-scale production would begin in 2000.
The so-called "wing drop" problem on the Super Hornet was first
noticed during flight testing more than six months ago. The jet will
bank suddenly and unexpectedly during nose-up maneuvers known as high
angle of attack.
In late September, at a fighter conference in London, Ronald
Harney, flight test leader of the Super Hornet project, called the
wing-drop anomaly "the toughest problem to date, at the heart of the
tactical maneuver envelope."
It was initially thought the problem could be solved with a
software fix. That has not worked as well as hoped, according to the
memo to Dalton, which was obtained by Defense Daily, an industry
publication.
John Douglas assistant secretary of the Navy for research, wrote
the memo based on information provided by Capt. James Godwin, the
Navy's Super Hornet Program manager.
"Numerous wind-tunnel-developed hardware and software solutions
have been tried on the test aircraft," the memo said. "To date, the
low-cost, quick fixes, though improving performance, have not re-
solved the issue."
The navy has pushed hard in Congress for the Super Hornet, which
it says is a revolutionary improvement over the existing F-18-Hornet.
The Super Hornet is bigger and has more range and capability than
the older Hornet. It also has substantially fewer parts.
But at a time of reduced military spending, the Super Hornet must
compete for funds with two other fighter projects - the F-22 Stealth
Fighter and the Joint strike Fighter. Boeing is involved with both.
Critics of the Super Hornet say its advantages over the current
Hornet don't justify the cost of building more than 700 of the
planes. Congress' General Accounting Office reached the same
conclusion.
The GAO report said the Super Hornet provides only "some improve-
ments over the current Hornet and recommended it be canceled.
But Cooper, the Congressional Research Service analyst, said the
Super Hornet will not be killed, even if the wing has to be rede-
signed and the Navy ends up with fewer planes.
"Despite the critics, these programs end up being funded anyway,"
he said. "I've been watching these programs for a long time. They
don't die. There's too much riding on them. It's impossible to say
what the Super Hornet program will look like in several years. Per-
haps some funding will be shifted away to the Joint Strike Fighter.
But it will almost certainly survive."
