The American T92 Self Propelled Gun artillery system was the perfect example of the need and advantages of a self propelled gun over towed guns. The M1918 240mm calibre towed artillery gun proved troublesome and time consuming to set up, traverse and move across the battlefield during World War 2.
In 1944 the development of a modified M26 Pershing tank chassis (T26E3) mounting the M1918 artillery gun started.The chassis was extended, an open structure to operate the gun was added and a massive single piece stabilization blade mounted on the rear.Designated the T92, 2 pilot models were ordered in March 1945 and completed in May. The war ended soon after and the vehicle did not enter production.
