Jets scrambling to defend a minor unit is a bad deal

[TarMinyatur]

Is there a way to deactivate the automatic scrambling of Jets?

If an opponent sends a Missile Needlejet to attack a ground unit near my base, one of my Missile Interceptors is scrambled. OK, I expect that. But my Interceptor does not benefit from its Air Superiority (SAM) ability.

The combat is resolved as 6 attack vs 6 attack. I guess this follows the rules in datalinks...but shouldn't it be 12 (for the SAM air unit) vs 6 (for the defending air unit)?
 
If I wait to attack that 6-1-10 Needlejet on the next turn, however, the same combat is resolved as 12 attack vs 1 defense! It's a huge difference.

So unless the threatened ground unit is very valuable, the scrambling of Interceptors is not a good idea.

Is the 12 attack vs 1 defense resolution a bug?
