Port Blair: D-Day here. It's not strongly defended, and I don't think Erik has/had any detection on the TFs involved.
He might load up airfields like Rangoon and Victoria Point. RN carriers are present to provide CAP (they aren't carrying any strike aircraft, as I do not anticipate a surface engagement nor the presence of enemy subs).
If the Allies can take Port Blair, Erik will then make deductions about threats to Malaya, Sumatra, etc. That, in turn, should lead to deductions about the stability of his army in Burma.
I don't have plans to invade deeper in the short term, so this is mainly to give the appearance of a threat on a new flank.
