I agree.
Personally, I never really found Strategic bombers worth using in any of my campaigns. Which is sad, because I think it could be a more efficient unit. So far, like the OP said, they are too easy to shoot down as they have no escort available (Fighters are not meant for that purpose obviously). That makes them rather useless, as you can't actually use their superior range.
Strategic bombers are expensive in production and require most advanced airfield - which is ok, but they donβt compensate with their stats. And yes, rockets are in general more effective, which is rather silly.
It should be a way to improve STR bombers and make them worth using, like e.g. a new escort fighters with a long range and high defense, but allowing them to operate from Carriers is IMO also idea in good direction.
