Notes:
Dialogue: The M270 launcher is the firing platform for the MLRS. It has a three man crew (a 13M10 driver, a 13M20 gunner, and a 13M30 section chief). It can be operated by one soldier in degraded operations. Each launcher has the on board capability to receive a fire mission, determine it’s location, compute firing data, orient on the target and fire. The SPLL consist of two major components: the M993 Carrier Vehicle and the M269 Launcher Loader Module.
The M993 Carrier is a longer version of the Bradley Fighting Vehicle with nearly 80% common components. When heaviest the launcher weighs approximately 24,036 kg (52,990 lbs). The launcher has a cruising range of 483 km and can be transported by C-141B and larger aircraft. The vehicle cab is constructed to give ballistic protection to the crew. It is fitted with a M13A1 gas particulate filter unit that protects the crew from chemical and biological agents and radioactive particles. It also has a vehicle cab overpressure system to protect the crew from toxic rocket and missile exhaust.
The M269 LLM consists of two sections: a mechanical section and an electrical section. These sections work together in order to perform all firing and non-firing functions. The LLM electrical section consists of three subsystems: the primary power supply, communications system and the fire control system. I will not focus on the electrical system during this class. You will receive a detailed briefing on the electrical section during the hands on block of instruction. The LLM mechanical section consists of the base, turret and cage assemblies. The base assembly provides for the physical mounting of the LLM to the carrier. Both the turret and base assemblies house the electronics and hydraulics of the launcher drive system that actually perform the rotation and elevation functions of the LLM. The cage assembly performs two major functions. First, the structure of the cage assembly aligns, holds and protects the pods. Second, the boom and hoist assemblies give the crew a built in ammunition loading and unloading capability.
