Overview
- The contract procures T408 engines for production Lots 9–13 and includes spares and sustainment services, with final assembly in Lynn, Massachusetts.
- Work runs through 2032, and the Navy estimates approximately $174 million in savings compared with single-year buys.
- Program officials say the multiyear structure provides a stable demand signal that supports supply-chain health and better pricing.
- Congress granted multiyear procurement authority in the FY-25 NDAA, and the Navy previously signed a $10.9 billion airframe deal with Sikorsky for up to 99 CH-53Ks.
- The Marine Corps has 23 CH-53Ks in service and plans its first Marine Expeditionary Unit deployment in FY-27 after a two-year schedule slip, while the 200-aircraft objective is under review due to fiscal reductions.
