Description
The Weapon System
The F101-102 engine is an augmented mixed flow turbofan engine, which is used exclusively by the Boeing B-1B Lancer strategic bomber. Four F101 engines equip the B-1B aircraft. The F101-102 is managed to safety standards established by the Propulsion Product Group Manager. In all cases, the F101 meets the goal of 0.5 Class A projected mishap between scheduled maintenance events. The F101 engine program utilizes a three level maintenance concept: 1) Organizational (Flight line), 2) Intermediate, and 3) Depot (Organic) maintenance. Issues relating to system safety, reliability and maintainability, repair, obsolescence, and environment are addressed through the Component Improvement Program (CIP).
The F118-100 engine is also an augmented mixed flow turbofan engine, which is used exclusively by the B-2 aircraft. The F118-100 is managed to safety standards established by the Propulsion Product Group Manager. In all cases, the F118 meets the goal of 0.5 Class A projected mishap before next scheduled maintenance opportunity. The F118 engine program utilizes a two level maintenance concept: 1) Organizational (Flight line), and 2) Depot (Organic) maintenance. Issues relating to system safety, reliability and maintainability, repair, obsolescence, and environment are addressed through the Component Improvement Program (CIP).
Description and Specifications

R-TOC Focus Areas: (Based on USD (AT&L) memorandum dated December 16, 2003.)
The R-TOC Vision: Through R-TOC principles, all defense systems will perform with increasing readiness and capability while avoiding increased operations and support resource costs and improving logistics footprint by institutionalizing the continuous implementation of innovative process and hardware improvements.
The R-TOC Goal: Maximize cost avoidance on total defense systems' FY 2010 O&S costs by offsetting 30 percent of the inflation predicted from an FY 2004 baseline.
- FY 2004 Baseline O&S Cost: To be determined.
- FY 2010 Forecasted O&S Cost: To be determined.
- FY 2010 Goal: (FY 2004 O&S Cost) * 5% = To be determined.
Major R-TOC Development Concepts that will be used to achieve the FY 2010 O&S cost reduction target. To be determined.
For the F101 engine, under the guidance of the PPGM and ASC/LP, several best practices and cost reduction initiatives have been institutionalized in the propulsion community. These include Reliability Centered Maintenance and a variety of agreements including: GE Corporate Contract, Performance Based Agreements with System Program Offices, Engine Life Management Plans, and a Memorandum of Agreement with the Defense Logistics Agency. All of the above programs have led to increased average time on wing and improved readiness. However, as a result of use and increased operations tempo, engine hardware is showing signs of fatigue and reduced mean time between failure (MTBF), thereby increasing costs to the user. Two projects currently in process to reduce total ownership costs are the Digital Electronic Control (DEC) installation program and the Aging Engine Upgrade (AEU), targeted for long term cost reduction.

These include Reliability Centered Maintenance and a variety of User Agreements including: GE Corporate Contract, Service Level Agreements with System Program Offices, Engine Life Management Plans, and a Memorandum of Agreement with the Defense Logistics Agency. All of the above programs/initiatives lead to increased average time on wing and improved readiness. However, through continued use and increased operations tempo, engine hardware tends to show signs of fatigue and reductions in mean time between failures (MTBF), ultimately increasing costs to the user. Two projects currently in process to reduce total ownership costs are the Digital Electronic Control (DEC) installation program and the Service Life Extension Program (SLEP), targeted for long term cost reduction.
