A Weapon That Will Turn Heads
Defense: Helmets that allow pilots to aim their missiles simply by looking at
targets could revolutionize combat.

EDWARDS AIR FORCE BASE -- F-16 fighter jet pilots testing a futuristic weapon
system are discovering that looks can indeed kill.

Test pilots here are flying with sophisticated helmets, resembling a bug's eye,
that allow them to aim their weapons and sensors simply by looking at potential
targets on the ground or in the air.

The helmets, when coupled with a highly maneuverable new missile that is close
to deployment, would enable fighter pilots to look over their shoulders and fire
instantly at targets, a feat that until now has been matched only in science
fiction movies. "It's going to revolutionize close-in dogfights," said Lt. Col.
Troy Fontaine, operational officer for the 416th Flight Test Squadron, which
recently began flying the helmets on F-16 fighter jets. "It'll give us air
superiority because we'll be able to see first and shoot first."

Despite significant advances in combat aircraft, the way fighter pilots have
engaged their targets has changed little since the birth of air combat using
biplanes during World War I. Though missiles have replaced machine guns, the
basics of a dogfight have not changed: A pilot must find the enemy, turn the
plane toward it and fire before flying away.

With the new system, success in combat may no longer depend on how well pilots
can maneuver their aircraft but on how fast they can turn their heads.

The headgear, formally the Joint Helmet-Mounted Cueing System, recently
completed initial tests on F-15 and F-18 fighters. More tests are planned for
the F-16 before deployment in about three years, Air Force officials said.

The Pentagon envisions buying as many as 2,000 helmets, and an advanced system
already is under development for the F-22 and the F-35 Joint Strike Fighter, the
next generation of fighter jets.

Boeing Co.'s military aircraft and missiles unit in St. Louis is the prime
contractor for the helmet system, but much of the development was done by San
Jose-based Vision Systems International, a joint venture of defense electronics
maker Rockwell Collins Inc. and an Israeli firm, Elbit. The helmets will be
manufactured by Vision Systems International.

The Pentagon has spent about $100million to develop the helmets and expects to
spend about $672million to acquire 1,880 of them, along with accessories and
modification kits to integrate the headgear into the various fighter jets. The
helmet itself will cost about $190,000 when full production begins, Pentagon
officials said.

Helmet-mounted display visors are not new. In the 1970s, F-4 Phantom pilots used
headgear with a visual target acquisition system, which transferred information
from the cockpit to the visor. But such rudimentary systems still required the
plane to be oriented toward a target.

The latest system, which has been in development for more than a decade, uses a
magnetic device to track head movement to determine where the pilot is looking
and then projects information about the target to the pilot's visor.

Though seemingly simple, the technology represents a breakthrough.

A pilot wearing the helmet can look out the side of the cockpit, spot an enemy
plane and then lock the missile's guidance system on the target before launching
the weapon--all within a few seconds.

The coordinates of the target are transmitted instantly to the missile, which
upon launch uses its own infrared and optic sensors to make the kill.

Much of the targeting information that the pilot sees is displayed on the right
side of the visor as small green-tinted circles, squares and numbers. When a
target is in the display's bull's-eye, the pilot pushes a button to launch the
missile.

But the ability to see and mark a target at extreme angles, known as high
off-bore sighting, is only as effective as the maneuverability of the missile,
defense officials say. And the Pentagon has been developing a generation of
missiles that can make sharp turns with very small radiuses.

The U.S. had decided not to develop a simple helmet-mounted display a decade ago
when the Soviet Union did, precisely because there were no weapons that could
take full advantage of the system.

The AIM-9X missile, under development by Raytheon Co. in Tucson, is designed
with a sophisticated rocket engine that can change directions using its
thrusters, making it the most maneuverable missile to date. Information about
how sharply and quickly it can turn is classified.

Last year the Pentagon awarded Raytheon an 18-year contract valued at $3 billion
to produce more than 10,000 missiles for both the Navy and the Air Force. Full
production is expected to begin next year.

Capt. Jason Clemens, an F-16 pilot who used the helmet for the first time
recently, says he also foresees the system dramatically improving air-to-ground
attacks. A pilot using the helmet, he notes, would be able to mark a target on
the ground for either a laser or a satellite-guided bomb.

"Instead of having to turn my [plane's] nose, I can visually make out the target
and drop a bomb, just like that," Clemens said. "I can be quicker and more
precise."

Pilots in the test program also appreciate that the technology has the advantage
of giving them the ability to see crucial aircraft information on their
helmets--such as speed, altitude and attitude--so they don't have to look down
at the cockpit instruments during an intense dogfight or bombing mission.

"It gives us a lot more situational awareness," said Capt. L. Najeeb Ahmed,
chief flight test engineer for the F-16. "We can keep our eyes on the enemy."

The biggest challenge is not technological, pilots and engineers say, but
retraining the pilots to understand they don't necessarily have to maneuver
their planes into position for attack.

Soon, pilots may no longer have to use their hands to explain how they yanked
and banked to get behind an enemy plane before shooting it down, a tactic that
has changed little in more than 80 years.

"It literally changes the rules of engagement," said Bill West, Raytheon's
development director for air-to-air missile programs. "It's going to take some
time for pilots to realize they are going to fight differently."

Pretty frikkin cool!

Thanks for educating me on the F-35 also, this is the first time I heard of it.

MiG29s have had a Helmet Mounted Sight System since they were introduced. Their IR missiles' seeker heads are slaved to the HMSS and can therefore acquire targets well off-axis. Plus, the missile can be launched with "English" in order to allow it to pull a lead pursuit on an off-axis target.
