For more than 50 years, Marsh Aviation Company has been a leader in engineering and innovation for performance- and reliability-oriented aircraft upgrades and modifications.

The company specializes in repurposing retired military airframes into modern, capable, efficient and cost-effective aircraft – often at a fraction of the cost of similar new aircraft. Many of these upgrades include conversion to modern and efficient Honeywell turbine powerplants with high-performance Hartzell propellers, modern avionics, and structural modification of the airframes to accommodate installation of new mission-specific systems.

Since the 1980s, Marsh is best known and respected for its expertise and success in modifying and upgrading variants of the Grumman S-2 and C-1 family of military airframes. Beginning with a proof-of-concept conversion of a piston-engined S-2A to turbine power, Marsh then developed a turbine conversion for six carrier-based military aircraft for Armada Argentina, the Argentine Navy.

Next came the addition of a proprietary Constant-flow Aerial Retardant Delivery System (CARDS) and the fully FAA Type Certificated Marsh S-2F3AT “Turbo Tracker”, “Initial Attack” aerial tanker was born. This led to contracts for a firefighting aircraft in Turkey, and for 23 Marsh S-2F3AT Air Tankers for the California Department of Fire Protection (CAL FIRE) see Marsh also adapted the CARDS for use in the Lockheed C-130, along with modifications for oil and chemical dispersion operations.

Other programs included upgrade and modifications on military variants of Cessna and Beechcraft aircraft and numerous OV-10 “Bronco” aircraft for the U.S. State Department and U.S. Air Force.


In 2011 Marsh Aviation was awarded a contract by Marinha do Brazil (the Brazilian Navy) for carrier-based KC-2 COD/AAR air-to-air refueling and utility aircraft. This multi-year $109 million contract will provide Brazil with an advanced, modern, and versatile addition to their Navy arsenal.


Bottom line, whatever your need for specialized military or utility aircraft, Marsh Aviation can help you design and build a quality, cost-effective solution.
