Advance Production Engineering of Law Subcaliber Trainer

Abstract

The report is of a study to reduce cost and increase manufacturing base for Rocket, Practice 35mm Subcaliber M73 and Modification Kit for M190 Launcher. The program concentrated on items which promised greatest improvement in cost and performance; e.g., Launcher Inner Tube Assembly and Rear Door Assembly; and Rocket Motor Case Warhead and Igniter. Significant contributions were made both to the production cost picture and to the performance of the weapon itself. The rocket motor is fabricated from a slug of carbon steel by the hot cup-cold draw method. The warhead is made of high-impact plastic with end item mixing, while the igniter is made of a polyethylene cup with a zinc die- cast primer housing thus eliminating the need of molding in the presence of explosives.
