‘We’ have been talking about that here some (my ‘group’ and I), and I agree that SA2 is a bit much for an aircraft (look at the cost). However, I think that it and other aircraft (of the same size, type, role, etc.) should have an additional ‘hit’ on them. So, instead of being disrupted or destroyed, they’re now disrupted, damaged, then destroyed.
And, there are ‘salvo’ rules floating around the net somewhere that seem to work well for rockets, and I think they could be slightly modified to work for carpet bombing. As it is, a bomb could work really well if they had to be placed on that hex (but automatically added 4 hexes to the distance of the aircraft; for non anti-air units shooting at it; as to represent the relative distance that it is ‘up’). I also like the bombardment and blast ideas as well (check back after it has been used AGAINST me!). I don’t think that it should have any AI/AT rating for ground units (only the bombing run ability), but have an AI (Still having the Anti-air ability so it needs 5+ to hit; inaccurate) rating against other aircraft.
As for the cost however, I think that is a bit shy of what I’d see it being. It would be a very powerful unit (10 dice, plus bombard and blast!), so the cost should reflect that. Perhaps around 30 points would better reflect a unit of this magnitude. A unit that can be brought in each turn, is hard to kill, and will very likely kill whatever it is aiming to kill (or at least have a high probability to do so with blast, bombard, and 10 dice).
This all simplifies it so that the unit now has one function, albeit a powerful one, to decimate a hex! Heck, to balance the inacurate a bit more, you could say that it has 12 dice (the cost easily justifies that or 14 dice against everything). But, once it is damaged, it will be VERY hard to do anything further with that unit… perhaps having it out for a turn per hit (optional ‘out’ time for repairs) could allow it to come back in ‘clean’… again, that is something that would obviously make the unit more valuable (read: expensive).
So:
Cost: 28
6/6
A
Bombing Run: Once per turn the Lancaster may make an attack against the hex that it is in or one of the forward adjacent hexes. This attack has 10 dice. This attack uses the Bombardment and Blast rules as well.
Inaccurate: Minus one on attack dice
Anti-Air: This unit uses it’s AI rating to attack other aircraft as normal, but may not use that rating to attack anything but aircraft. This unit also ignores the penalty for attacking aircraft.
Heavy Aircraft: This aircraft unit has an additional ‘hit’ before being destroyed.
AI 8/6/-
AT -/-/-
