 ST. LOUIS, Oct. 1 /PRNewswire/ -- McDonnell Douglas delivered the 6,000th Advanced Concept Ejection Seat, or ACES II, built by the company for the U.S. Air Force.
 The seat, which was accepted by the program's Air Force Defense Plant Representative Office Sept. 15, will be delivered to the Israeli Air Force for installation into an F-15 Eagle.
 Along with the seat's delivery at the company's Florida Missile Production facility in Titusville, the company also recognized the 300th ACES II save. As of Sept. 11, 1993, the ACES II has been credited with 301 saves since it was introduced in 1978, including 20 saves in 1993.
 During Operation Desert Shield and Operation Desert Storm, the ACES II system delivered a 100 percent success rate with 15 attempts resulting in 15 successful ejections. It has a perfect in-envelope record.
 "Pilots put their trust in the quality of our hardware, and we, in turn, have a responsibility to ensure that our product is the best it can be," Dan Anglim, manager of McDonnell Douglas' escape systems, said at the delivery ceremony. "The service record of the ACES II seat is testimony to our continuing acceptance of that responsibility and our commitment to quality."
 ACES II is a rugged, light-weight, easy-to-maintain ejection seat developed by Douglas Aircraft Co. under contract to the U.S. Air Force. The high-performance escape sye?m is currently used on F-15A/B/C/D/E, F-16A/B/C/D, B-1B, B-2, A-10, and F-117A aircraft, as well as on the F-15s and F-16s of 16 other nations. It also has been selected for the F-22 Advanced Tactical Fighter. Additionally, McDonnell Douglas is under contract to the U.S. Air Force and the Navy to develop and demonstrate advanced propulsion, guidance and life support technologies to offer even greater margins of safety and performance than what is available on current models.
 ACES II provides optimum performance across an escape envelope from 0 to 600 knots equivalent airspeed and 0 to 50,000 feet altitude and is designed to safely eject a crew member under zero-zero conditions. At low speed, the ACES II produces a parachute 1.8 seconds after initiation, faster than even the Russian K-36 super seat. A unique gyro-controlled system -- called STAPAC -- stabilizes the seat during the ejection.
 ACES II can provide trajectory divergence so that two crew members can be ejected in tandem or side-by-side with no interference in their escape system components. ACES II uses a drogue parachute for stabilization and deceleration in a high-speed escape and for stabilization during descent from high altitudes. The recovery parachute is mortar-deployed to assure positive, consistent deployment and is reefed for additional crew member protection.
 Sensors on the seat detect altitude and airspeed and send the information to the recovery sequencing subsystem, which then directs the operation of the seat according to the situation. In a low-speed situation, the drogue chute would not be deployed, while in a high- altitude ejection, the deployment of the recovery chute would be delayed until the seat reached a lower altitude.
 The seat also is equipped with an emergency oxygen supply for crew members descending from a high altitude ejection, a survival kit, and a harness release mechanism to release the crewman from the seat during automatic recovery.
 ACES II seats have been manufactured at the McDonnell Douglas Aerospace Florida Missile Production facility since November 1989, when the ACES II program was transferred from Douglas Aircraft. Prior to the move, McDonnell Douglas was already producing portions of the ACES II seat at its Titusville location.
 The delivery of the 1,000th seat to be produced in its entirety by the Titusville facility also was accepted by the Air Force Sept. 15.
