The SM-31 Stiletto™ is an all-new single-engine, supersonic military aircraft that will be produced as the SM-31T two seat tandem supersonic Advanced Pilot Trainer and Light Fighter and as the SM-31S single seat Light Fighter. A high performance, fifth generation, low-observable stealth aircraft, the SM-31 is of advanced configuration and features an internal weapons bay, planform alignment, a 2-D thrust vectoring nozzle and a V-tail. With advanced embedded sensors, a compact AESA fire control radar, integrated communications, navigation and identification (CNI) avionics and optional multi-function advanced datalink and comprehensive electronic warfare and self-protection suite
Powered by a single Honeywell F125-GA-100, F125X or F125XX afterburning turbofan to provide continuous airflow at all angles of attack, the SM-31 has bifurcated Diverterless Supersonic Inlets (DSIs) that blend into the aircraft’s faceted fuselage. The SM-31 has a low aspect ratio wing with 30 leading edge sweep, 176 sq ft of area and an aspect ratio of 3.27. The wing is equipped with slats, slotted flaps, ailerons and a proven thin wing section. For pitch and yaw authority the SM-31 features a prominent V-tail with all moving rudder-vader. Constructed from aluminum lithium and titanium the SM-31 will benefit from a near monocoque structural configuration that combines aluminum lithium honeycomb sandwich skins with integrated titanium and aluminum lithium bulkheads and frames.
