![]() But we need to remember that the research that determined that was only being done in the 40s and 50s. Sitting here in 2019 it is obvious to is that copper is much preferable for shape charge liners. That type manual wouldn't get into the internals of the warhead, but the motor body is steel. The 1944 weapons and ammo TM says 0.5lb pentolite charge. So that implies anything before then is steel. According to this, the Bazooka HEAT rounds adopted copper liners in APR 1945. I'm not 100% what the "obvious reasons" are for using steel rather than copper, but my guess is wartime shortages of copper due to other uses and better availability of steel. If you like at of 70 it discusses materials for liners. I found this research report from the period. Especially as it refers to a cluttered up range with a mix of ordnance. I wouldn't take it as too definitive on its own. The Corps of Engineers paper you linked is very recent and deals with a cleanup project. Has anyone seen anything that definitively states the use of mild steel liners in M6 series rocket prior to M6A5? US Army Ordnance Training & Heritage Center actually replied, though they didn't have any data. I tried e-mailing everyone mentioned in the report. This may be a confusion with the larger T59 series of full-bore 2.36 inch experimental rockets. ![]() This is contradicted by the 1945 edition of TM 9-1950, which lists the M6A5 as a service round, and both the 1950 edition of same and OP 1720 which give a figure of 0.5lb Pentolite. However, the source looses value due to clearly false/mistaken claim that M6A5 is a early-50s rocket with larger 0.95lb Comp B charge. ![]() Penetration is slightly greater than known M6A3 performance, probably due to increased charge size.įinal Conventional Explosives Safety Submission Fort McClellan AL states M6A3 uses mild steel liner, citing unnamed documents. Utilized the available steel liner of the 2.36-inch HE, AT rocket (described elsewhere). I know that the M6A5 bazooka rocket uses a copper shaped charge liner, but I have not found conclusive evidence for previous warheads using mild steel.Ĭavity Charge Container Mark 1 section implies steel liner for early M6AX rockets I've been researching the World War Two 2.36inch bazooka and its ammunition for a few years and have run into a wall on a particular topic. ![]()
