HVAC, Refrigeration, Automation, and Control Systems Parts and Services for MSC vessels

The Department of the Navy Military Sealift Command established a Master IDIQ on April 10, 2025, for HVAC, refrigeration, automation, and control systems parts and services supporting MSC vessels, with ordering authority extending through October 9, 2030. The vehicle carries no set-aside and operates as an unrestricted, multiple-award structure.

Seventeen task orders have been awarded since establishment, with fourteen issued in 2025 and three in 2026. Activity has slowed markedly—three orders in the first four months of 2026 compared to fourteen in all of 2025—suggesting either seasonal demand patterns or a recent inventory buildup. All $10.9 million in combined potential value has been obligated across the 17 awards, indicating the vehicle is actively funding obligations rather than accumulating unspent capacity.

Trident Maritime Systems, Inc. dominates the vehicle, holding 15 of 17 orders and $10.7 million of the $10.9 million combined potential value. Johnson Controls, Inc. holds the remaining 2 orders worth $160 thousand. Competition is effectively one-vendor concentrated, with Trident capturing roughly 98 percent of the vehicle's value. Funding flows almost entirely through Military Sealift Command itself (15 orders, $10.7 million), with a secondary trickle through the broader Department of the Navy (2 orders, $188 thousand).

Task-order values cluster at the low end, with three minimum-guarantee orders of $3,500 each, numerous component and repair orders in the $10,000–$160,000 range, and two outlier mega-orders: a $5.28 million crane overhaul (USS Emory S. Land) and a $4.83 million cargo and sail service crane buy, both awarded to Trident in mid-2025. Durations are brief—most completion dates fall within 2–4 months of award—reflecting reactive maintenance and parts provisioning for an operating fleet rather than long-cycle development or installation work.

Place of performance is vessel-specific and operational, with orders supporting named MSC supply ships (USNS Lewis and Clark, USNS Sacagawea, USNS Earl Warren, USNS RFK, USNS Cesar Chavez, USS Emory S. Land, and others). The scope is narrowly defined: cooling coils, air handling units, cargo refrigeration plants, AC motors, variable frequency drives, crane systems, and in-service technical support and grooming of HVAC and refrigeration plants.

Four years of ordering authority remain, but the rate of new orders has declined sharply. Prospective vendors should assess whether the narrow, prime-dominated competitive structure and maintenance-driven demand pattern align with their market positioning.
