Southwestern Controls prepared a proposal for the missile division of a major electronics company. The Customer asked Southwestern Controls to design and prototype a hydraulic subassembly for a ship-launched missile assembly tool. The tool was used to affix the nosecone to the body of the missile, within a range of specified torque values.

Southwestern Controls engineers incorporated an electro-hydraulic solution including: a fixed displacement hydraulic pump with four actuators; a four-path rotary swivel and the accompanying valves; an accumulator; a filter; pressure switches; and a ladder logic-based control system.
