SOLE SOURCE JUSTIFICATION

Background The Turbine Pump Ejection System (TPES) MK 17 Mod 0 provides the impulse launch capability to torpedo tubes installed onboard USS OHIO Class submarines. The Gear Train Assembly converts the high-speed, low-torque input from the turbine to the low-speed, high-torque output required to drive the axial flow pump. The Gear Train End Mounts secure the Gear Train Assembly to the Mount Cylinder. The Naval Undersea Warfare Center Division Newport (NUWCDIVNPT) is the In Service Engineering Activity (ISEA) for the MK 17 TPES and is responsible for life cycle support. This includes supporting the MK 17 TPES refurbishment program.

Requirement NUWCDIVNPT has a requirement to inspect, and repair or replace a set of Gear Train End Mount Assemblies P/Ns 3181110 and 3181113.

Implications if not awarded The repaired or replaced Gear Train End Mount Assemblies will be used as a rotatable spare to expedite the refurbishment of Mk 17 Mod 0 TPES, or as part of a Mk 17 Mod 0 TPES designated for laboratory testing. Failure to have repaired or replaced Gear Train End Mount Assemblies will lengthen the refurbishment span of Mk 17 Mod 0 TPES, and inhibit the laboratory testing of design upgrades to the Mk 17 Mod 0 TPES. Both will adversely impact the capability and mission readiness of the Submarine Fleet.

Why Only One Source The Gear Train End Mount Assemblies contain a proprietary urethane formulation which is only obtainable from Harkness Industries. Harkness Industries is the only entity known to possess the special tooling and fixtures (urethane mold and torque test fixture) required to manufacture and repair the Gear Train End Mount Assemblies. No other manufacturer possesses the technical information associated with the Gear Train End Mount Assemblies. The Government does not possess the technical information associated with the Gear Train End Mount Assemblies and therefore cannot provide it to another manufacturer.

Conclusion Harkness Industries is the only vendor capable of repairing or replacing the Mk 17 Mod 0 TPES Gear Train End Mount Assemblies. As the current requirement cannot be performed by any other manufacturer, it is recommended that it be awarded to Harkness Industries on a sole source basis.
