The Department of Defense, through the Naval Air Systems Command, is seeking to procure overhaul and repair services for the Tail Gearbox Assembly (Part Number X0606-00315-045) for the CH-53K helicopter, along with associated engineering follow-on support. This procurement is critical for maintaining the operational readiness and performance of the CH-53K, a vital asset for military operations. The contract is expected to be awarded under a sole-source basis to Sikorsky, a Lockheed Martin Company, due to its unique capabilities as the Original Equipment Manufacturer (OEM) and its proprietary technical knowledge, with an estimated cost of $1.368 billion funded through the U.S. Marine Corps budget.
