The DD/AC at Gibraltar can reach the german boats, or block the strait. That gives the UK atleast 1 DD, 1 AC, 3 fig, 1 tac vs the german fleet.
They can also just park the dd and/or ac in the SZ near GB to soak the shore shots and to draw some of the German airforce away (possibly).
OK thats fine. UK can move:
1 CV, 1-2 fighters, 1 DD to stay in SZ 110 and Germany has 1 BB, 1 CA, plus planes
Lets look at the numbers:
UK defending: 2/4/4/2 vs 4/3 and whatever planes it needs, plus the subs 2-3 of them ( think i might lose 2 perhaps 3 from G1 attacks)
Now this means UK has two less fours defending UK leaving 9-10 infantry 1 tactical bomber, and 1 fighter
Germany in that case needs to allocate vs the 12 point UK threat with about 18 points of its own and could do it with 16 because the BB takes 2 hits as well as her Carrier
I suggest Germany uses 1 BB, 1 CV, 1 CA, 1 tactical Bomber, 1 fighter, 1 bomber = 18 points which is a total of 8 hits vs UK fleet of 12 points and 5 hits. This will do the job
Germany now has for sea lion:
3 tanks, 3 infantry, 5 fighters, 2 tactical = 35 points 13 units vs UK of 9-10 infantry 1 tactical , 1 fighter = 27 points 11-12 units
Its still broken.
if UK buys all naval with 27-29 IPC… say what then? UK now has just 2 infantry and 2 planes defending and instead UK built a navy for Germany to defeat.
Germany can take out UK with 3 tanks 3 infantry plus just a few planes, the rest will attack the UK fleet.
I think UK might go with what kind of fleet vs a potential German fleet of 1 BB, 1 CA, 1 CV, up to 6 fighters, 3 tactical, 1 bomber. I just think we are just shifting the numbers around that they are not going anywhere.
I will look at the rules for subs and how this interacts with transports.
