M250-KS4 SSE tooling

The Surface Combatant/Gas Turbines Engineering Branch of the Naval Surface Warfare Center, Philadelphia Division (NSWCPD) is the In-Service Engineering Agent (ISEA) for the Ship Service Gas Turbine Generator (SSGTG). The 250-KS4 (or Redundant Independent Mechanical Start System (RIMSS) gas turbine engine is one of two ways to start the SSGTG. It is also the only means to start a SSGTG in a dark ship scenario. The Navy is establishing intermediate-level (I-level) procedures for the replacement of turbine assemblies at Regional Maintenance Center (RMC) turbine shops. This initiative will provide the Navy with a repair capability for 250-KS4s not previously possessed, significantly reducing repair turnaround times and enabling the refurbishment of previously unusable carcasses. The procurement of specialized support equipment (SSE) is a critical prerequisite for implementing these repair procedures.
