The F-15C was configured to carry ASATs in the 80s. There was a
trial done.
The ASAT missile was nearly 18
feet in length and weighed 2700 lbs, small enough to be carried on
the centerline pylon of an F-15. It consisted of a Boeing
Short-Range Attack Missile first-stage motor, a Ling-Temco-Vought
Corporation (LTV) Altair III second-stage motor, and an LTV
miniature homing vehicle.
The delivery aircraft would be launched into an area below the path
of the oncoming target satellite. Pulling up into a steep climb,
the F-15 would release its weapon into a small launch "window.'' If
all went well, the homing vehicle would vector itself directly into
the target's path and destroy it by smashing directly into it. At
the extremely high closing speeds of the two objects, no explosives
would be necessary.
Following the first captive-carry flight in 1982, test sorties
continued systematically. The first ASAT launch from an F-15 took
place early in 1984 and was directed merely to a predetermined
point in space, as a test of the missile's propulsion system.
Maj. Doug Pearson's exacting Launch, at precisely 38,100 ft.,
1.9gs, and .934 MachBy September 1985, all was finally ready for a
test against an orbiting satellite. On Sept. 13, Maj. Wilbert D.
"Doug" Pearson, the director of the F-15 ASAT CTF, took off on a
crucial mission that required him to fly an extraordinarily
exacting profile in order to arrive at a precise firing location at
exactly the right time. Flying at Mach 1.22 some 200 miles west of
Vandenberg Air Force Base, he executed a 3.8g pull-up to a climb
angle of 65 degrees.
The missile automatically launched itself at 38,100 ft. Minutes
later, orbiting peacefully 345 miles above the Pacific Ocean, an
obsolete satellite named P78-1 was suddenly shattered into pieces.
Pearson had become the world's first pilot ever to shoot down a
satellite. To this day, now Maj. Gen. Doug Pearson remains, as Air
Force Materiel Command Commander Gen. Lester Lyles recently
observed, the first and only "space ace."
