After looking at the game table (board) I can understand why this idea is intriguing. But after thinking a bit, Russia & GB can very easily keep any the black sea ship free with their air force. At least if I was Russia, I would sink anything built there. Also would love Germany to spend that kind of $$ ion an IC & navy instead of tanks, art & inf……still, it might be fun to give it a go sometime.
I once built an airbase in Romania in a Tech game where I had rockets and paratroopers. If you had that, I guess you could protect a TT with scrambled fighters and hit Caucusus from the Ukraine.
The fighters need to get out of uk or he needs to transport units off for you to be able to do sea lion (assuming he buys 9 inf or 6 inf 1 fighter to defend london). If he buys elsewhere on the map sure by all means go for it.
Make sure your Italy can bomb the airbase on round 2… in case he tries to repair it after Germany’s turn.
Make sure you get 1 destroyer or he can stop your attack with subs.
