The last 6 WAC Corporal Bs to fly were used in the Bumper program as the second stage atop captured V-2 missiles in early air-light and staging experiments. For Bumper, the WAC Corporal was modified to provide stability in excess of Mach 5 by increasing the number of fins to four and increasing their size. The WAC Corporal had to be modified so that the engine ignition would be initiated by the integrating accelerometer of the V-2 stage just before cutoff of the V-2 engine. The WAC Corporal was spin-stabilized by two solid rockets placed between the oxidizer and fuel tanks. The Bumper/WAC had a payload capacity of 50 pounds and carried a Doppler transmitter/receiver which transmitted the nose cone temperature as well as velocity information. There were 6 Bumper flights from White Sands, the first two carrying solid-fueled dummy WACs. Flight number six had a failure on the V-2. Bumper 7 and 8, the last two flights of the Bumper program, were the first launches from the new Joint Long-Range Proving Ground at Cocoa Beach, Florida, which would later be known as Cape Canaveral. The reason for the move was the intention to use a depressed trajectory to achieve velocities in the vicinity of Mach 7 from . This would entail flights downrange in excess of , which would exceed the boundaries of White Sands. The WAC/Bumper flights were: Bu-1 May 15, 1948 Dummy WAC Corporal Bu-2 August 10, 1948 Dummy WAC Corporal Bu-3 September 30,
