## What project 675129 buys

The B-52J Commercial Engine Replacement Program (CERP) supports nuclear and conventional operations by replacing the current TF33-PW-103 engine on the B-52H aircraft. The TF33-PW-103 engine is experiencing significant supportability challenges due to diminished manufacturing sources and obsolescent technologies. This program will replace the current TF33-PW-103 engine with new military derivative commercial Rolls-Royce F130 engines of similar size, weight, and thrust characteristics. Along with the new engines, CERP will replace associated subsystems, such as engine struts and nacelles, the electrical power generation system, and cockpit displays. The development, production and installation of new engines and related subsystems will replace the legacy equipment on all 76 B-52H aircraft. Any B-52H aircraft modified with the new commercial engines and associated subsystems will be designated as B-52J. B-52J CERP is taking advantage of advances in technology and on-going development efforts to acquire engines and integrate them into the B-52. The new technology will increase both the overall reliability and maintainability of the propulsion system and produce additional electrical power generation capabilities for emerging requirements. The B-52J CERP will allow the operational command (Air Force Global Strike Command) to fully utilize the capabilities of the B-52 aircraft to employ an array of nuclear and conventional weapons while increasing fuel efficiency and extending the range/loiter capabilities of the aircraft. In addition, applicable training devices must be developed, modified and/or upgraded in conjunction with the aircraft modifications. As B-52J CERP brings additional capability to the B-52, emerging security/certification requirements (nuclear hardening, cyber security, program protection, etc.) are being addressed. Several concurrent aircraft upgrades during the B-52J CERP necessitate temporary facilities or facility upgrades/modifications. In addition, the upgrades may necessitate studies be performed to determine optimal engine installation and deployment options. Additionally, funds will be used to procure long lead material and installation for test aircraft to include engines and all required associated components in the B-52J CERP configuration baseline (i.e. RMP A & B EMD kits).

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### B-52 CERP

Continue execution of the Post-CDR Development contract. Continue ordering hardware for two test aircraft on material contracts and deliver necessary components to modify the aircraft. Continue F130 engine integration testing. Begin modification of test aircraft.
