Really it’s to have Kamikazes available on turn 1. If you put 2 of them on this ship, you have a pair of 9-dice bomb attacks to start the game for 6 points. You also forfeit a pair of aircraft from your capacity.
Technically it'd be zero as the kamikaze is Landbased.
What about this,
Land Squadron - Units with the Land Based ability can be deployed on this unit. They must return to the landbase if they leave this units sector.
Desperation - Once per turn, a friendly aircraft that is destroyed this turn may make an attack against a ship in its sector. If it does, the attack is reduced by 1 attack die.
Whatever we do on this, I did like the sound of a fly off strike for a two engine unit(s), in a sort of transit role. Which can be launched but must then fly off to a land base, if it's not a kamikaze obviously.
