Inscription. The T-162 was one of a number of American heavy, self-propelled artillery prototypes in the early Cold War. This artillery piece was envisioned to combine mobility with a high-powered, long-range gun. In 1950, the Army Equipment Development Committee recommended a gun of about 170mm be developed to replace the M40 155mm Gun Motor Carriage (GMC) or self-propelled "Long Tom". In response, the 175mm gun, T-181, was designated the appropriate weapon and a self-propelled chassis was prepared. Benefitting from experience with the models T97 155mm GMC and T108 8-inch Howitzer Motor Carriage, the T162 differed in some respects. It possessed a longer tube, wider hull and tracks (28 inch) and a steering bar (in place of wobble stick or steering wheel). Despite some advanced features, air mobility became a critical requirement. The T-162 was determined to be too heavy at 49 tons and too large. Consequently, the project was discarded. Manufactured by Pacific Car & Foundry in Renton, Washington, this was the last of three produced.
