Build a transport at south africa, move the egypt one to the red sea SZ with the french destroyer.
Shuttle units from South African factory to egypt every turn.
Not a bad plan, but probably needs to be defended well since Germany can quickly get airpower in that area, and the Japs are right around the corner.
If Sea Lion does not need to be repelled, taking the CV, DD from Gibraltar and the CA off South America, the CA off Egypt and the DD you mention is a pretty good fleet. Maybe the French DD can be used as a stationary defense at one of the TRS points.
