Description:
a. The M190 subcaliber launcher with M73 subcaliber rocket can be used against all solid stationary or moving targets. Together they can be used in all training phases, from fixed firing live to simulated situations, such as a "trainfire" type operation. b. The M190 subcaliber launcher is a tubular, telescoping, smooth-bore, openbreech weapon. c. The M73 subcaliber rocket consists of a spotting head, a motor closure, a rocket motor and an igniter assembly. The spotting head contains the same flash composition used in the M80 explosive simulator (TM 9-1370-203-34&P) to assist in locating the fired rocket. The forward end of the motor closure provides a cavity that contains a base detonating fuze and a primer. The motor case contains tubular grains or propellant. The rocket is stabilized by six molded, plastic fins. The external appearance of the M190 subcaliber is almost identical to the M72A1. The M190 differs from the tactical launcher M72A1 by having a subcaliber rocket and a quick release primer housing door to simplify reloading. The used M72A1 launcher is modified by use of a conversion kit to produce the M190 subcaliber launcher.
Use:
To train personnel in the operation and use of the 66-mm antitank rocket, M72 series.
Functioning:
Extending the launcher into the extended or firing position automatically locks the weapon. After the trigger safety handle is released, the trigger can be depressed. This releases the channel assembly which drives the firing pin into the primer of the rocket motor igniter. This ignites the black powder in the flash tube, which, in turn, ignites the integral igniter of the rocket motor. The igniter initiates the propellant. The burning propellant propels the rocket from the launcher. When the spotting head of the rocket strikes a target, an inertia-driven firing pin sets off the primer. The primer in turn sets off the spotting head which produces a flash, noise and white smoke.
