Lockheed Martin F-35 Lightning II for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized. The single-engined F-35 closely resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from its sibling. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship. Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter.
