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 Laboratorys ARL Transonic Range facility on 6 December 1994 and 8 December 1994. The projectiles experienced launch accelerations of 21,000 gs and 14,000 gs, 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 FMFM 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.
