The Coast Guard awarded a contract for the production of eight wire harness kits for its MH-60T Sustainment Program to Tyonek Machining and Fabrication on Jan. 19. Total value of the contract is $6.7 million.

Each wire harness kit consists of 79 individual, interconnected wire harnesses that provide electrical power and transmit signals for nearly all of the medium range recovery helicopter’s systems and subsystems. The wire harnesses are being replaced concurrently with the helicopter hull as part of a program to extend the service life of the Coast Guard’s current fleet of MH-60T helicopters for up to an additional 20,000 flight hours. Wire harnesses installed on the hulls will be a 100 percent form, fit and function replacement of the existing wiring; they do not increase the overall capability or add new capabilities to the MH-60T aircraft.

Tyonek was awarded an initial contract for the non-recurring engineering and production of seven wire harness kits in May 2019. The Coast Guard entered into an interim contract with Tyonek for an additional eight wire harnesses (8-15), which will enable the program to continue Service Life Extension Program activities without any breaks in production until wire harness deliveries commence under a future full rate production effort.
