Seeing it’s armament and top speed, I’d see 7.0 - 7.7 being a fair br.
You can’t put a Cold War 80s jet with early Cold War/WW2 planes. Would look silly.
You literally can, and it’s already a thing.
I mean we already have a 70s one fighting ww2 planes

Fair
Okay so the A-1H should go from 6.3 to 9.0
It also has flares and chaff.
I think this plane should be added as long as it gets all of its jamming + chaff and flares as that would make low tier air to air missiles worthless forcing a gun run.
Also if the snail where to bless this improvised bomber with some cargo bay door parachute payloads I am sure people will kindly air drop your Amazon delivery right onto your cap your trying to capture.
The overall plane is balanced going into the game and I am sure some people will include it into there line ups and depending on the munitions Gaijin blesses it with it may just work in naval.
It could be interesting to see it included in a potential infantry DLC. Dropping BMDs and VDV as a spawn point.
That would be OP or AA food depending on the enemy team. But this could be a cool plane to see because of all the load outs in theory this bomber can use. Just think of all the sea mines you can push out the back.
