ARDEC Report on 76MM Gun M1A1 and M1A2

76mm ammoFor those looking for a detailed report on the effectiveness of US 76mm tank guns, check out this new technical report from ARDEC, the U.S. Army Armament Research, Development and Engineering Center.  Released in January of 2018, this document is a 58 page PDF and is a rather thorough examination of the topic.  Download the report here.

Report Abstract:

This report provides an analysis of the U.S. anti-tank technology during World War II. A ballistic analysis is used to corroborate the battlefield history and gain an understanding of the physical and technological factors that spurred the development of the M1 series 76-mm Gun and family of ammunition.

The technical manual (TM) 9-1907 was published 23 September 1944, but it was missing performance data for the 76-mm hyper-velocity, armor-piercing (HVAP) shell and any information for performance of the U.S. anti-tank capabilities against the German Panther tank. Battle history indicates there was a technological capability gap against upgraded Panzer armor. This report attempts to use hand calculations and modeling and
simulation (PRODAS) to fill in the information that is missing in TM 9-1907. The analysis offers the reader a greater engineering comprehension of the challenges faced between June 1944 and May 1945 and the circumstances necessitating the rapid fielding of the 76-mm HVAP shell after German capability upgrades were encountered in the European Theater of Operations from Normandy to the Battle of the Bulge (June to December 1944).
