Repair Depot

Bringing Affordable Navy Repair Depot Operations to Industry
L3 Power Paragon has developed and maintained a complete and comprehensive Naval Repair Depot Operation for over 10 years.

Close working relationships and quality repair work are the corner stone to a solid business relationship with the U.S. Navy. Following a Quality Production and Repair assurance of MIL-Q-9858A with ISO 9001 certification in progress, our low turnaround times and competitive prices help to support the readiness of the fleet. Because our depot facility maintains and stocks a complete line of repair parts, L3 PPI can restore equipment to an operable or “ready for issue” condition quickly and efficiently. The depot facility can also accommodate a “rotatable pool” approach where a restored unit will be immediately shipped to replace a unit scheduled for repair.
