Fighters that never flew ! your own list

Mine are these 2

Fighter-bomber version of the F-101 Voodoo, which could have been the workhorse of the bombing campaign in vietnam but still would be able to defend itself better against the Migs than F-105

AAMs 4 x AIM-4
Bombload approx 10,000 lb

Fighter-bomber version of Sukhoi Su-15 flagon, a cheaper less sophisticated supplement to the Su-24.Having enhanced dogfighting capability due to better wings and a reasonable bombload.It would be a better alternative to the specialist Su-25 which is useless in the fighter role.And a replacement of MiG-21 in the VVS regiments

Bombload approx 6,600 lb
