Abstract : Under the Hardened Subminiature Telemetry and Sensor Systems (HSTSS) Program, two 120-mm M831 projectiles were modified to test the survivability of a multichip module (MCM) and a solid-polymer electrolyte-battery technology. Tests were conducted at the U.S. Army Research Laboratory's (ARL) Transonic Range facility on 6 December 1994 and 8 December 1994. The projectiles experienced launch accelerations of 21,000 g's and 14,000 g's, respectively. Modifications included replacing the M831 spike-nose assembly with a custom-built assembly, which housed an MCM, two solid-polymer batteries arranged with different orientations, and a three-channel FM/FM telemetry system. Malfunctions with the telemetry link on the first firing yielded inconclusive results about the MCM survival of the gun launch; however, this problem did not completely annihilate the evidence which suggested that the solid-polymer batteries survived. Results from the second firing showed that both the MCM and the solid-polymer batteries survived the gun launch.
