https://nationalinterest.org/blog/buzz/ ... f-35-86941The Tempest mockup suggests a relatively large single-seat, twin-engine delta-wing fighter with a cranked trailing edge and two vertical stabilizers (tail fins) canted inwards as on the F-22 stealth fighter. According to analyst Justin Bronk, these last improve maneuverability and suggest emphasis on kinematic performance over pure stealth. The larger airframe also implies a desire for greater range and weapons load than an F-35 can muster in stealth mode. However, reportedly no performance parameters such as maximum speed, range, radar cross-section etc. were stated in the presentation.
A fighter needs to perform as a fighter first and foremost.
