Capable of level speeds in excess of Mach 4 with a tactical radius of over 1,000 nm on internal fuel, the SM-39 benefits from a planform aligned trapezoidal wing and all moving horizontal tail. With a large array AESA radar, adaptive avionics and EW, internal weapons carriage and thrust vectoring exhaust nozzles, the SM-39 is a low-observable, supermaneuverable aircraft for both land based and naval carrier operations.

Pioneering new approaches in aerodynamics, high temperature airframe structures, efficient variable cycle turbine propulsion, active low-observability and boundary layer control, integrated avionics, synthetic intelligence, enhanced lethality and offensive/defensive directed energy weapons, the SM-39 will be produced in single seat (SM-39S), two seat tandem (SM-39T) and unpiloted autonomous (SM-39U) configurations. The SM-39 will be developed to work in concert with tethered and untethered Collaborative Combat Aircraft including Stavatti’s own SM-31U “Steadfast Stiletto” solution.

Now under development by Stavatti to meet US service needs as well as to serve as an export fighter to replace allied F-15C/D/E/EX/J/K/Q/S aircraft, the SM-39 will be competitively priced and offer significant cost savings over similar class platforms. Designed for exportability, Stavatti began submitting DSP-5 applications to the Directorate of Defense Trade Controls (DDTC) to receive prior approval to market the SM-39 to US allies currently operating the F-15 in April 2023, including Case Number 050773088.

Addressing a global market need for 6th generation Air Dominance Fighters, Stavatti projects that up to 100 SM-39 aircraft will be produced annually by Stavatti at production facilities in the USA, creating more than 2,200 direct jobs for two to five decades.
