RADM Sakamaki takes command of 21st Air Flotilla.
Nells and Zeros based at Rangoon are setup for a max escorted range 14 strike if the CVLs can be spotted again tomorrow.
CA Div 2 is already moving south after bombardment of Chittagong, but BB Div 1 and CA Div 1 are ordered south to avoid sea and land based allied strikes. Most dangerous for BB1 and CA1 is a rush forward by the allied CVLs, but if they do that they should get pummeled by the Rangoon Nells.
