Reliability Enhancement & Reengining Program

Abstract

C-5 Reliability Enhancement and Re-engining Program (RERP): RERP is a comprehensive modernization effort to improve aircraft reliability, maintainability, and availability. RERP will enable the C-5 to achieve wartime mission requirements by increasing fleet availability (mission capable rate, departure reliability). This effort centers around replacing the current TF39 engines with more reliable, Commercial Off-the-Shelf CF6 turbofan engines with increased take-off thrust and stage three noise compliance. The new engines, military designation F-138-GE-100, increase payload capability and access to Communications, Navigation, Surveillance/Air Traffic Management (CNS/ATM) airspace. The modification also decreases aircraft time to climb, increases engine-out climb gradient for takeoff, improves transportation system throughput, and decreases engine removals. Additionally, numerous other system modifications will be performed to increase fleet availability. Increased costs led to a review of total program requirements. On 14 Feb 08, the USD(AT&L) certified a restructured RERP to Congress. This restructured program reduced RERP scope to include only 49 production aircraft (47 C-5Bs and 2 C-5Cs). The AF was directed to fully fund RERP to the OSD Cost Analysis Improvement Group (CAIG) Independent Cost Estimate (ICE). On 14 Mar 08 the USD(AT&L) conducted a successful Milestone C (MS C) Defense Acquisition Board (DAB). The USD(AT&L) signed the Acquisition Program Baseline (APB) reflecting the N-M certification and the MS C approval on 24 Jun 08. Equipment Diminishing Manufacturing Source (DMS) issues will be resolved to support continued operations through studies, bridge buys, life of type buys, development and redesign efforts. On 7 Oct 10, USD AT&L conducted a successful Full Rate Production (FRP) Decision Acquisition Board (DAB) and approved the C-5 RERP FRP ADM for lots 5 – 7; directed Air Force to fully fund RERP to the OSD Cost Assessment and Program Evaluation (CAPE) Independent Cost Estimate (ICE) for RDT&E; re-designated C-5 RERP as an Acquisition Category IC program. This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate production funding in the current or subsequent fiscal year. The Prior Years funding estimate is $1,472.363M. FY2010: Funding supports RERP design, development, engineering change orders, and contractor/government test. Mission support funding is required for program office operations. FY10 funding is also required to continue the development/delivery of aircrew/maintenance training devices. FY2011: Funding supports RERP design, development, engineering change orders, contractor/government test, and technical order publications. Mission support funding is required for program office operations. FY11 funding is also required to design, build, test and initiate delivery of aircrew/maintenance training devices. FY2012: Funding supports RERP design, development, engineering change orders, contractor/government test, and technical order publication in support of the correction of Qualification Operational Test & Evaluation deficiency reports. Mission support funding is required for program office operations. FY12 funding is also required to finalize the testing and development/delivery of aircrew/maintenance training devices and efforts to continue to minimize divergence between AMP and RERP baselines. FY12 is the last year of RDT&E funding.
