I can’t even put rockets with any other weapon on without it saying that it is too fat. Come on Gaijin
If you believe this limitation is historically inaccurate then make a bug report using proper sourcing to get it changed, a forum post won’t do nuthin sadly. Iirc some naval aircraft have lighter limitations ingame tha they are actually capable of due to real life weight restrictions associated with carrier operations, perhaps it’s one of them?
