CH-53K T408 Engine Lot 10 Advanced Acquisition Contract Modification

The Naval Air Systems Command awarded a sole-source Advanced Acquisition Contract modification, N0001924C0019 P00002, to General Electric Aviation in Lynn, Massachusetts. This action facilitates the procurement of long-lead items necessary for Lot 10 Full Rate Production T408 Engines supporting the CH-53K Helicopter Program. The contract was awarded without full and open competition under the statutory authority of 10 U.S.C. 2304(c)(1) and FAR 6.302-1(a)(2), as General Electric is identified as the only responsible source with the proprietary technical data, facilities, and specialized expertise required to produce the unique components for engine integration. This procurement falls under the broader scope of Class Justification and Approval CJ&A 20-311, which authorizes sole-source procurement for T408 engines and associated support for Lots 6 through 13. This overarching authority, which expires on September 30, 2031, covers a baseline of 561 engines and spares with a potential increase to 784. Cost reasonableness for these efforts is determined through analysis by the Defense Contract Management Agency and the Defense Contract Audit Agency, and there are currently no plans to compete future contracts for these specific supplies.
