SUPERSONIC FIRING
Supersonic munition firing from F-22 Raptor
Boeing, Lockheed F-22 test team scores Direct Hit in Supersonic,
High-Altitude JDAM Drop

The US Air Force F-22 Combined Test Force team of Boeing, Lockheed
Martin and Air Force pilots has successfully demonstrated the F-22
Raptor's ability to release a munition at supersonic speed, high
altitude and standoff range during a recent joint developmental and
operational test at White Sands Missile Range, NM.
An Air Force F-22 air dominance fighter, flying at a speed of Mach 1.5
and an altitude of 50,000 feet, released a GPS-aided, 1,000-pound
Joint Direct Attack Munition (JDAM) from a range of 24 nautical miles,
destroying a ground target in the aircraft's fastest and highest JDAM
delivery to date. Nellis Air Force Base (AFB), Nev., supplied the live
warhead.
The ability to release a munition at supersonic speeds and standoff
ranges greatly enhances the aircrew's survivability against heavily
defended targets.
"We've already demonstrated the airplane's ability to operate with
virtual impunity in the air-to-air realm, but successfully attacking a
ground target at this speed, altitude and range shows that to be true
in the air-to-ground mission as well," said pilot Lt. Col. Raymond
"Buzz" Toth following the test. "The Raptor is ready to fight and is
uniquely capable of supporting Air Force and Joint Command objectives
against any enemy."
Success of the standoff delivery is due in part to the Raptor
avionics' ability to compute an accurate Launch Acceptability Region (LAR),
the area in the sky from which the pilot can release a weapon to
successfully attack the desired target. The LAR supersonic algorithm,
developed by a Boeing collaboration of F-22, Phantom Works and JDAM
engineers, factors in navigation, weather, target and weapon
information.
"The LAR algorithm developed by this interdisciplinary team offers the
robust capability of updating to the latest weapon performance without
requiring a new software build," said Paul Bay, vice president and
F-22 program manager at Boeing. "Our JDAM, Phantom Works and F-22
units, working with Lockheed Martin's Air Combat Simulator team in
Marietta, each brought a specialized expertise that was essential to
making the LAR integration a success."
John E. Paquet, director of F-22 Mission Systems and Software at
Lockheed Martin, added, "The successful drop of the JDAM from the
Raptor has demonstrated our systems engineering process throughout the
design life cycle. Early in the design phase, we brought Raptor pilots
to the high-fidelity Air Combat Simulator in Marietta. Ga., and
received valuable feedback on the new JDAM LAR. We were able to
quickly incorporate their feedback into the software design, and the
results of that collaborative effort were evident in the recent test."
The F-22 is capable of dominating any adversary through an unmatched
combination of stealth, supercruise speed, agility and a complete view
of the battlespace provided by an advanced sensor suite. The Raptor
will enable combat commanders to change the way wars are fought over
the next 40 years.
Prime contractor Lockheed Martin has delivered 71 F-22s to the Air
Force, with 107 Raptors currently on contract. The fighter is assigned
to four bases across the U.S. Testing is conducted at Edwards AFB,
Calif.; tactics development takes place at Nellis AFB, Nev.; pilots
and maintenance teams receive training at Tyndall AFB, Fla.; and
operational F-22s of the 1 st Fighter Wing are assigned to Langley
AFB, Va.
A GPS-aided, near-precision weapon, the JDAM guidance kit is capable
of guiding inventory bombs ranging from 500 to 2,000 pounds, as
demonstrated in extensive U.S. Air Force and Navy global operations.
Since 1998, Boeing has produced more than 140,000 JDAM guidance kits
for 16 domestic and international customers.
The F-22 Raptor, the world's most advanced fifth-generation fighter,
is built by Lockheed Martin in partnership with Boeing and Pratt &
Whitney. Parts and subsystems are provided by approximately 1,000
suppliers in 42 states. F-22 production takes place at Lockheed Martin
Aeronautics facilities in Palmdale, Calif.; Meridian, Miss.; Marietta,
Ga.; and Fort Worth, Texas, as well as at Boeing's Seattle, Wash.,
plant. Final assembly and initial flight-testing of the Raptor occur
at the Marietta facilities.
Headquartered in Bethesda, Md., Lockheed Martin employs about 135,000
people worldwide and is principally engaged in the research, design,
development, manufacture, integration and sustainment of advanced
technology systems, products and services. The corporation reported
2005 sales of $37.2 billion.
A unit of The Boeing Company, Boeing Integrated Defense Systems is one
of the world's largest space and defense businesses. Headquartered in
St. Louis, Boeing Integrated Defense Systems is a $30.8 billion
business. It provides network-centric system solutions to its global
military, government and commercial customers. It is a leading
provider of intelligence, surveillance and reconnaissance systems; the
world's largest military aircraft manufacturer; the world's largest
satellite manufacturer; a foremost developer of advanced concepts and
technologies; a leading provider of space-based communications; the
primary systems integrator for U.S. missile defense; NASA's largest
contractor; and a global leader in sustainment solutions and launch
services.
