SPRDL1-24-R-0006 (JA-00735)

Previous J&A: SPRDL1-20-R-0022 technical data, USG data rights, or manufacturing knowledge are not available to permit acquisition from other sources, nor qualification testing of another part, nor use of a second source part in the intended application. Although, by DoD-STD-100 definition, altered and selected items shall have an adequate Technical Data Package (TDP), data review discloses that required data or data rights are not in USG possession and cannot be economically obtained. If one source is available, AMCs 3, 4, or 5 are valid. If at least two sources exist, AMCs 1 or 2 are valid.

NSN 2815-01-439-8164 is for the 6.5L Turbo Engine with Container Kit internal combustion diesel engine and used in the Enhanced Capacity Vehicle (ECV) series HMMWV. While this kit is coded to the USG, the major item inside the container is the engine, for which the USG does not have data rights. The 6.5L Turbo engine described within this document is supplied to the U.S. Army by AMG. In total this engine is used on seven different configurations of the HMMWV. This configuration of the 6.5L engine is turbo charged and variants are for the ECV series of the older generation of HMMWV.

This engine is a direct service replacement for the HMMWVs.

This particular contract action is to supply the 6.5L Turbo Engine with Container Kit dressed Diesel Engine for use during general maintenance and rebuilding of the HMMWV as instructed in the HMMWV IADS Technical Manual, National Maintenance Work Requirement publication NMWR 9-2815-274, dated April 2012 for 6.5L engine overhaul procedures used at Red River Army Depot. All levels of repair keep support costs down by reusing parts or rebuilding complete assemblies wherever possible.

However, given the age of some of these parts, full replacement is sometimes required.

Authority Cited: The statutory authority permitting other than full and open competition for this effort is 10 United States Code (U.S.C.) 3204(a)(1) as implemented by the Federal Acquisition Regulation (FAR) 6.302-1, Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements.

5. Reason for Authority Cited:

a. Background:

The following is a brief history of this engine. The engine used in the HMMWV was originally designed and developed by Detroit Diesel in 1982 for use in General Motors (GM) commercial products as a gasoline engine. At that time, Detroit Diesel was a subsidiary of GM. For reasons unknown, this engine was converted from gasoline to diesel and then offered to the USG in the HMMWV. It was originally introduced into the HMMWV fleet as a 6.2L naturally aspirated (non-Turbocharged) power plant and incorporated into the first HMMWV production run. An upgrade followed in 1992 when a 6.5L non-Turbo version was developed as an improvement over the 6.2L in terms of engine performance and power. In 1995, the turbocharged 6.5L variant of the engine was introduced to further increase performance and power output to meet the needs of the HMMWV’s ever-increasing weight. This engine’s basic block has been used in the HMMWV for the past 34 years. Finally, on or around calendar year 2000, GM sold the tooling and production rights for the 6.5L engine to AMG and withdrew from the 6.5L

Previous J&A: SPRDL1-20-R-0022 business almost entirely. Since that transition, AMG has been building and supplying engines to HMMWV production and fulfilling sustainment requirements. Both GM and AMG have demonstrated the capability to provide this item to the USG, based on past performance. However, AMG is currently the only source of supply capable of providing new engines since they maintain the tooling and assembly line purchased from GM.

This version of a compression ignition engine, otherwise known as a diesel engine, was originally designed and developed by GM subsidiary Detroit Diesel for use in the GM commercial vehicle line dating back to the early 1980’s. To speed up the development and procurement process, the USG agreed to the Original Equipment Manufacturer’s (OEM) request to retain the data rights to the commercial engine itself. The USG does own the rights to the accessory drive and hang on items, often referred to as the engine dress, but that is exterior of the engine and does not provide the necessary information for full and open competition. AMG and GM co-integrated this engine into the HMMWV during the development stage of the vehicle platform. AMG is the OEM of the HMMWV FOV and GM is the originator of the engine.

b. Costs:

There are no known funding efforts in progress at this time to acquire the commercially controlled data needed to make NSN 2815-01-439-8164 fully competitive.

Consequently, there are no current plans to acquire a fully competitive TDP, because funds are not available to acquire the necessary data.

c. Alternatives:

There are two options available to the USG to obtain the technical data for this item: (i) Reverse Engineer the existing engine (if the USG is no longer able to procure the item) or (ii) Research and Development of replacement Army engine design.

(i) Reverse Engineering (RE) and Remanufacturing

The primary objective of reverse engineering is the development of unrestricted technical data, adequate for competitive procurement, through engineering evaluations of existing hardware, in this case the 6.5L Turbo Engine with Container Kit. Advantages in this RE solution include minimized vehicle integration costs, as the RE product would be a direct replacement for the original 6.5L Engine. The Army would own the resultant technical data including any Three-Dimensional models and drawings. This technique could also be applied to any component of the 6.5L, enabling competitive pricing. The disadvantages of this process are its relatively high cost and long lead times.

Costs and schedules were estimated for the 6.5L engine RE effort. Primary Components included the engine block, head casting, crankshaft, connecting rod, pistons, flywheel, and the flywheel housing, etc. Envelope drawings can also be used in certain scenarios that allow for alternate substitute parts. Using an envelope drawing that includes all the connections of the alternate part to the engine could lower the cost versus creating a full TDP. Further investigation will be needed on a part-by-part basis.
