I was looking at the re-engined B52 project which was supposed to extend its 8800sm unrefueled combat range/10,145sm ferry range by 40%, making it 12,320/14,203sm.

What is the longest range unrefueled production aircraft? Is this it? No ferry tanks or one off stcs allowed. Legitimate programs not yet in production are ok, meaning funded or otherwise substantiated.

  • $\begingroup$ @sophit The Airbus Aircraft Characteristics for the A380 show a ferry range of about 9600 NM (without wind), so significantly less than the ~12300 NM claimed by the B52. $\endgroup$

    $\begingroup$ @DaveGremlin: It didn't even need fuel to absolutely obliterate the record! $\endgroup$ Jun 27, 2023 at 12:31

    $\begingroup$ @DaveGremlin Clever thought, but I would put drop tanks in the same category as ferry tanks and the shuttle external tank is one giant drop tank. $\endgroup$
