1 INTRODUCTION

1.1 Scope. This statement of work (SOW) defines the contractor’s efforts required to conduct non-destructive and destructive/functional testing of eighteen (18) government-furnished Tomahawk

Block IV Engine Start Cartridges (Williams part number (P/N) 65029).

1.2 Order of Precedence. In the event of inconsistency among requirements, the following descending order of precedence shall apply:

a. The Delivery Order including Statement of Work

b. Item Specifications

1.3 Background. FY24 will be the fourth Service Life Assessment Program (SLAP) testing of the

Tomahawk Block IV F415 Engine Start Cartridge. Testing shall be conducted with the process, procedures, and equipment consistent with those used in Acceptance Test Procedure (ATP) for

Start Cartridge P/N 65029 and Start Cartridge P/N 57815, Prepared for: Williams International, ATP 8319003, current revision. The Naval Surface Warfare Center, Indian Head Division (NSWC

IHD), Code E14 manages the engine program and will furnish the fleet-returned units.

1.4 Item Description. The Tomahawk Block IV F415-WR-400 Turbofan Engine Start Cartridge (P/N

65029) is used to start the Tomahawk Block IV F415-WR-400 Turbofan Engine after the rocket motor burnout at the start of the mission cruise phase. The engine start cartridge assembly consists of a stainless steel case (17-4PH), enclosing a dual bridgewire initiator mounted on the forward end of the case that is fired to start the propellant burning. The high-pressure hot gas is ejected through the discharge port on the aft end of the case. Tubing on the turbofan engine conducts the gas to a nozzle that impinges the gas against the turbine rotor blades, spinning the engine up to starting speed. The engine start cartridge was originally developed for the Tri-Service Standoff Attack

Missile (TSSAM) in the late 1980’s and is used on the German “Taurus” cruise missile. Figure 1 is a picture of an engine start cartridge.
