Doesn't take any skill to sink a ship, bomb a toolshed or milk run a base, so why should they get their name in lights?
ack-ack
Not sure you have thought this one all the way through.
To get you "name in lights" for killing a ship, you actually have to
survive your bomb run and land successfully. This would discourage the use of lancstukas, which is generally the "easy way" ships are sunk. Instead it encourages the bombers to fly higher, which gives the ship the opportunity to turn out of the way. This makes sinking them a little more challenging, increasing their survivability, which would ultimately prolong those ship-to-shore fights so many enjoy.
I don't see a downside to this.
