The Stiletto was a medium interceptor sold by the now-defunct company Elio-Harman Aerospace in the early 26th century SEY. It was one of the last spacecraft designs commissioned by the United Nations of Earth (UNE) and was used specifically to intercept enemy bombers. The Stiletto was withdrawn from service in 2580 in favor of the Aegis Dynamics Gladius following issues with its supply chain and the design's inability to adapt to rapid advances in shield technology.
