Design, engineer and manufacture a reusable enclosure to cover the aircraft launch catapults on the carrier deck during repairs. These units need to be watertight when installed and need to store efficiently without disassembly when not in use. The 30’-0” long units are design to lap over each other to create a watertight enclosure when installed. They have casters to ease movement on the aircraft deck. When not in use, the individual sections are designed to stack on top of each other up to 6 high.
