Thermal Warning Device Program 155mm M185 Howitzer M109A1/A2/A3

Abstract

A Product Improvement Program was undertaken to provide a thermal warning device to measure the temperature of the M185 Howitzer tube forcing cone area from the tube outside diameter and provide a readout to the user at the breech end. This would warn the gun crew when a dangerous temperature level had been attained, as well as permit a higher rate of fire than current procedures allow. The plan was to adapt the thermal warning device from the 155mm M198 Howitzer to the 155mm M109A1/A2/A3 Howitzer. The major problem required developing a method to attach the temperature sensor to a cannon tube which recoils through concentric recoil bearings without reducing the fatigue life of the cannon. After a suitable attachment method had been developed and successfully tested, the program was terminated by ARRCOM because of funding priorities.
