The U.S. Marine Corps is adding another UC-12W+ twin-engine turboprop aircraft to strengthen its ability to rapidly move personnel, priority cargo and critical supplies across and within operational theaters. The $18.56 million acquisition expands a light airlift capability built around the Beechcraft King Air 350 family, allowing the service to conduct time-sensitive transport missions without committing larger tactical airlifters.
The U.S. Department of Defense announced the award to Textron Aviation on September 28, 2026, with the contract covering one UC-12W+ and associated spare parts. The aircraft will support Marine Corps requirements for operational support airlift, whose primary mission is moving high-priority passengers and cargo quickly between and within theaters of operations.

Textron Aviation received the $18,557,557 firm-fixed-price contract from Naval Air Systems Command at Patuxent River, Maryland. Fiscal 2026 aircraft procurement funds cover the full amount at award, while production work will be split between Wichita, Kansas, at 80%, and Chihuahua, Mexico, at the remaining 20%. Completion is scheduled for December 2029, and the contract was awarded without competition.
The procurement follows a May 2026 Naval Air Systems Command notice describing the UC-12W+ as an FAA type-certified commercial cargo and passenger transport derivative of the Beechcraft King Air 350. That requirement called for one aircraft together with non-recurring engineering, engineering changes, and initial spares, with Textron identified as the aircraft’s sole designer, developer, and manufacturer.
The UC-12 family provides the U.S. Navy and U.S. Marine Corps with a comparatively small aircraft for missions where the payload does not justify using a larger transport aircraft. NAVAIR identifies the Huron’s missions as high-priority personnel and cargo transportation, courier flights, medical evacuation, humanitarian assistance, range clearance, multi-engine pilot training, and support for testing activities. Its cabin can be reconfigured for passengers, cargo, or a combination of both.
The existing UC-12W is a military derivative of the King Air 350 and represents a significant performance improvement over the older UC-12F and UC-12M aircraft derived from the King Air 200. Marine Corps documentation lists the UC-12W with two Pratt & Whitney PT6A-60A turboprop engines, a maximum takeoff weight of 16,500 pounds and a two-person flight crew.
The U.S. Marine Corps operational-support documentation lists the UC-12W as having a cruise speed of about 280 knots and a range of about 1,500 nautical miles with wing-tank fuel, increasing to about 2,000 nautical miles with extended-range tanks. The aircraft can operate at altitudes up to 35,000 feet and carry eight passengers with 500 pounds of cargo in one documented configuration.
Beyond basic transport performance, the UC-12W configuration incorporates equipment intended to make the aircraft useful in military airspace and deployed operations. Marine Corps documentation identifies a Mode V-capable transponder, encrypted ARC-210 radio, high-frequency communications, tactical air navigation equipment, and aircraft survivability equipment, enabling the aircraft and its crew to operate within the Marine Air-Ground Task Force command-and-control architecture.
The aircraft’s operational value is particularly apparent in distributed logistics. The U.S. Marine Corps operational support airlift is intended to provide time-sensitive movement of high-priority passengers and cargo, and the service lists the UC-12W as one of its dedicated assets for this mission. A smaller turboprop can therefore move personnel, replacement components, or other urgent loads without consuming the capacity and operating resources of larger aircraft such as the KC-130J.
The September award also fits into a broader U.S. Marine Corps effort to modernize its UC-12 inventory. NAVAIR currently describes the UC-12W as both operational and in production, listing nine aircraft in inventory against a projected inventory of 30. The service has historically operated older UC-12F and UC-12M aircraft alongside the newer W model, making continued procurement part of a longer-term transition toward the more capable King Air 350-based configuration.
Earlier U.S. Marine Corps planning has pointed toward further modernization through King Air B360CER-based aircraft. A previous government procurement notice sought 18 new UC-12W aircraft with extended-range fuel tanks, oceanic communications equipment, four-bladed propellers, brake de-icing and an alternate pressurization mode supporting air-ambulance operations. Those requirements illustrate the service’s emphasis on combining routine transport efficiency with longer-range and more flexible expeditionary operations.
The latest acquisition should consequently be viewed less as the purchase of a single utility aircraft than as an incremental reinforcement of the Marine Corps’ distributed logistics network. As Marine units increasingly operate across dispersed locations, particularly across the long distances associated with Indo-Pacific operations, aircraft capable of moving small but urgent loads can complement heavier airlift by connecting headquarters, aviation units and forward locations more efficiently.
With delivery scheduled by December 2029, the new UC-12W+ will add capacity for missions where speed, range, and flexibility matter more than heavy payload. Its combination of a configurable cabin, extended-range potential, military communications, and survivability equipment gives the U.S. Marine Corps another way to move personnel and mission-critical supplies rapidly across a distributed battlespace while preserving larger transport aircraft for missions requiring substantially greater capacity.
