Boeing has started publicly marketing two concepts for a stealthy, tailless, supercruising strike fighter to replace its F/A-18E/F Super Hornet after 2025. Both twin-engine concepts, which feature optionally-piloted cockpits, resemble a modern-day replacement for the ill-fated A-12 Avenger. The carrier-based stealth bomber project was cancelled in 1991 amid cost overruns and technical problems.
