The two contractors involved in Project Spike, General Dynamics and Ling-TEMCO-Vought (LTV), designed very different miniature homing vehicles. This plastic model of LTV’s vehicle, ultimately became the concept for the later Air-launched ASAT, The vehicles were designed to be launched from an F-106 fighter using a standard Anti-Radiation Missile (ARM) under the right wing of the F-106 (F-106A 59-0795 was used) and was designed to destroy a satellite by impact. The many thrusters on both vehicles were necessary to balance them and adjust their trajectories in flight.
