The O-2 SKYMASTER / GOLDEN HAWK MK I and MK II is a twin-engine, centerline thrust utility aircraft with 12 hours of endurance and 187 knot cruise airspeeds.

The Golden Hawk Mk I (C-337 chassis) and Mk II (O-2 chassis) are an exclusive modification to one of the world's most capable and versatile light Forward Air Control (FAC) militarized aircraft, the Cessna 337 Skymaster, also known through its military designation, the Cessna O-2 Super Skymaster. This aircraft was the mainstay of the FAC community during the Vietnam War, flying thousands of combat missions marking targets and coordinating air attack missions as a forward air controller (FAC), doing utility work and performing light reconnaissance.

Today, TF Hawk has taken this superb aircraft and upgraded it across the board, combining modern avionics and lightweight PolyArmor with extended range tanks and the new, soon to be FAA certified Delta Hawk diesel engine. These engines run on either Jet A (or GOST standard TS-1 jet fuel) or truck diesel fuel, thereby eliminating the need to secure a reliable stockpile of 100LL AvGas to support the aircraft's operations.

The Delta Hawk engines and other modifications that TF Hawk makes to the aircraft together yield much higher performance than the USAF Cessna O-2 Super Skymaster. For instance, the upgraded aircraft enjoys an unprecedented 12 hours of endurance, making it a highly cost-effective alternative to UAVs, performing the same missions at a fraction of the cost. In addition, the aircraft can successfully perform its mission even on the hottest summer days in the desert.

The Golden Hawk conversion is revolutionary, taking a proven, capable combat aircraft and turning it into an upgraded, high performance platform, ready and able to undertake a wide range of missions and roles to support security operations worldwide.

All new avionics, a standard Garmin GNS-530A GPS Moving Map (and NAV/COM/ILS) and more are equipped on all of TF Hawk's aircraft, as well as UHF and VHF radios, providing the full spectrum of communications options for military or civilian applications (including law enforcement operations).
