Lightweight Towed Howitzer Demonstrator. Phase 1 and Partial Phase 2. Volume F. Systems Engineering Analysis (QA, Test Plans).
Abstract
The LTHD (Lightweight Towed Howitzer Demonstrator) was to be a 9,000 lb equivalent to the M198, transportable via Blackhawk helicopter, with reduced emplacement time using fewer personnel. The FMC design achieved weight reduction via a mortar-like configuration, composites structure, and hydraulic actuators. Recovery of power from the recoil system, in turn, facilitated crew reduction via hydraulic emplacement, four-way joystick tube lay, and power ramming. FM completed Concept Development (PH I) and two-thirds of Detailed Design (Ph II) prior to funds running out.
