The B-37 Gailtean (English: sylph) is a single-seat, twin-engine stealth strike aircraft designed and built by the Ossorian aerospace defense company Tionscail Ríoga Aeraspáis (TRA). The Gailtean uses a trapezoidal wing configuration as well as an all-moving butterfly tail to reduce aerodynamic drag at transonic speeds, as well as various stealth features including serpentine air intakes to reduce its radar signature and heat-ablating tiles around its exhaust troughs to reduce its infrared signature from ground-based detection, and is also capable of supercruising. It is outfitted with a single weapons bay with a rotary launcher designed to make use of CSN-standard weapons and perform a variety of strike missions, including interdiction and SEAD.
