Gimlet (rocket) clip capable of fitting the internal rocket bays of the F4D Skyray interceptor was also developed. Following a flyoff against the T-214 rocket, which indicated the necessity to modify the rocket motor to reduce the Gimlet's visual signature, the Navy directed the development of a modified, 'hybrid' rocket, using the T-214's tail; this became known as "T-Gimlet". The modified rocket was considered to be suitable for the Navy's purposes; both the original Gimlet and the T-Gimlet were ordered for production, a 5 million dollar USD contract being allotted to start production at the Shumaker Naval Ammunition Depot in Arkansas.

Shaped charge developed for piercing thick steel armor be adapted to the task of accelerating shock waves. The resulting device, looking a little like a wind tunnel, is called a Voitenko compressor. The Voitenko compressor initially separates a test gas from a shaped charge with a malleable steel plate. When the shaped charge detonates, most of its energy is focused on the steel plate, driving it forward and pushing the test gas ahead of it. Ames translated this idea into a self-destroying shock tube. A 66-pound shaped charge accelerated the gas in a 3-cm glass-walled tube 2 meters in length. The velocity
