LOCKHEED-MARTIN
F-22 ADVANCED STEALTH TACTICAL
FIGHTER
The Lockheed-Martin F-22 Raptor represents the greatest advance
in fighter-aircraft capability in 50 years. It brings the largest
increase in sustained speed since the advent of the jet, flying
most of its missions at speeds other fighters can only attain for
short periods. The F-22 Raptor can also, using its advanced thrust-vectoring
system and supercruise capability, accelerate and maneuver at speeds
today's fighter jets struggle to maintain in a straight line.
The F-22 equals, and probably surpasses, the agility of any other
fighter. Its stealth characteristics which descend from the success
of the F-117 stealth fighter and B-2 stealth bomber provide invisibility
against most radars and sensors. Its integrated avionics, equal
in power to seven Cray supercomputers, and sensor-fused displays
are a generation ahead of anything under test elsewhere.
The F-22's primary mission is air superiority, defined by the
USAF as "the ability to achieve local air control at a time and
place of our own choosing." The odds are in favor of the side with
the faster aircraft with greater range, operating under the fewest
artificial constraints. The Raptor's secondary goal is to destroy
as many of the enemy's front-line fighters as possible for the smallest
possible number of losses.
The F-22 is designed to be immune to deep stalls - stalls from
which the aircraft can't recover from with normal control outputs
- and to recover from high-alpha, post-stall conditions with both
engines flamed out. The F-22 is also the first fighter to be designed
from the outset to use vectored thrust for control. While thrust-vectoring
isn't used to expand the flight envelope, it does help the aircraft
get from one maneuver state to another more quickly.
