美陆军与休斯公司开始对“轻量级大气层外弹射体(LEAP)”样机进行地面试验。 LEAP是地面配备型战略导弹防御系统之一,在大气层外对再入体(核弹头)进行撞击破坏。空军/波音公司的LEAP还要晚1个月进行试验。陆军/休斯公司集团的试验是在爱德华兹空军基地进行。样机重5kg,在束缚状态下试验,以10秒时间模拟实际飞行状态,轨道操纵装置(OMS)驱动约100次,姿态控制系统(RCS)驱动约1000次,消耗推进剂约60％。漂浮试验在飞机库内进行,在离地面3m上漂浮,驱动OMS
The U.S. Army and Hughes started ground trials of the Lightweight Atmospheric Exterior Projectile (LEAP) prototype. LEAP is one of the ground-equipped strategic missile defense systems that impacts and re-enters the body (nuclear warhead) outside the atmosphere. Air Force / Boeing LEAP also test one month later. Army / Hughes Test Group conducted at Edwards Air Force Base. The prototype weighed 5 kg and was tested in a restrained state to simulate the actual flight state in 10 seconds. The Orbiter (OMS) was driven about 100 times and the attitude control system (RCS) was driven about 1000 times, consuming approximately 60% of the propellant. Float test in the hangar, floating 3m above the ground, driving OMS
