Contract N6134026P1011 was awarded on March 9, 2026, to Thern Inc of Winona, Minnesota, for a total amount of $49,340.00. This firm-fixed-price procurement, managed by the Naval Air Warfare Center Training Systems Division under NAICS code 333923, was a total small business set-aside. The contract required the manufacture and delivery of one specialized Thern 4HPF3M-S1 helical-parallel gear power winch assembly to replace a damaged unit on a Helicopter Rescue Hoist Trainer. The winch assembly must feature a 1.5 hp Baldor motor, an SEW Eurodrive gear reducer with a 43.26:1 ratio, a dual braking system, and a heavy-duty frame. Key custom modifications include a 7.5 inch diameter by 14 inch width grooved drum for 3/16 inch wire rope, a pressure roller to prevent bird-nesting, and a rotary limit switch for over-travel protection. The unit requires a corrosion-resistant gray epoxy finish with a zinc-rich primer on the frame and drum, and a black finish on the motor and reducer. Delivery was required within 10 months of award to Norfolk, Virginia. The contractor was mandated to comply with MIL-STD-130 and MIL-STD-129 for unique item identification and shipment marking. Inspection and acceptance were conducted by the government at the delivery destination, with invoicing and receiving reports processed electronically through the Wide Area WorkFlow system.
