PERFORMANCE WORK STATEMENT (ATTACHMENT 7)

Surveillance Towed Array Sensor System-Expeditionary (SURTASS-E) Support Vessel (long-term)

1.1 Mission: The Military Sealift Command (MSC) requests one US flagged or foreign flagged (to be reflagged US) vessel required to tow an acoustic array in support of U.S. Navy Operations. This is a mission essential requirement which will require a mission essential contractor services plan (MECSP, Part X(z)).

1.2 Area of Operation: The vessel must be capable of worldwide operations. This includes support in all ocean basins of the world from the Arctic to the Antarctic during seasonally ice- free periods, when waters are navigable without ice-breaking classification but must comply with Category C of the IMO Polar Code for open-water polar transits. The vessel operator must also be capable of sustaining the vessel worldwide.

1.3 Operating Scenario: The vessel will tow a passive acoustic monitoring system, between 4-6 knots, 24hours/day for up to a 45-day event. The ship will need to be able to tow on a directed heading within 5 degrees for extended periods at slow speed. Because of the type of acoustic system employed, the ability of the vessel to maintain heading stability is critical.
