Let's talk range.


One of the major raps against the F-35 is that its a short ranged fighter.  But lets compare its combat radius with that of the premier fighter in the world today, the F-22.  From Wikipedia.

F-22 Performance Data...
Performance
  • Maximum speed:

    • At altitude: Mach 2.25 (1,500 mph, 2,410 km/h)[88]
    • Supercruise: Mach 1.82 (1,220 mph, 1,963 km/h)[88]
  • Range: 1,600 nmi (1,840 mi, 2,960 km) with 2 external fuel tanks
  • Combat radius: 410 nmi[189] (471 mi, 759 km)
  • Ferry range: 2,000 mi (1,738 nmi, 3,219 km)
  • Service ceiling: 65,000 ft (19,812 m)
  • Wing loading: 77 lb/ft² (375 kg/m²)
  • Thrust/weight: 1.08 (1.26 with loaded weight & 50% fuel)
  • Maximum design g-load: -3.0/+9.0 g
F-35 Performance Data...
Performance
  • Maximum speed: Mach 1.67[269] (1,283 mph, 2,065 km/h)
  • Range: 1,200 nmi (2,220 km) on internal fuel[270]
  • Combat radius: 610 nmi (1,110 km) on internal fuel[270]
  • Service ceiling: 60,000 ft[271] (18,288 m)
  • Rate of climb: classified (not publicly available)
  • Wing loading: 91.4 lb/ft² (446 kg/m²)
  • Thrust/weight: **With full fuel: 0.84;[59]

    • With 50% fuel: 1.04 B:[59]
  • g-Limits: 9 g[nb 4]
Seems like the F-35 isn't as short ranged as many noted authors would have us believe.  A comparison of legacy aircraft with comparable combat loads would also show them to be lacking in comparison to the F-35 too.  Don't believe the trolls.

The F-35 is a winner!
