Improvising stronger air defence for Force Z

Taking command of Force Z on 2 December 1941, what anti-aircraft improvements could be assembled locally, and could they stop the historical attack?

The proposal adds available machine guns and experienced gunners, checks ammunition and clarifies fighter support. Extra 3.7-inch guns are rejected because they would require a separate logistical system, and the response also expands into concentrating more ships.

The counterfactual begins by clarifying whether the RAF's statement about unavailable air support means fighters or bombers. Local air-defence personnel with light machine guns are then considered as extra shipboard gunners. Their experience is an attraction, while the 3.7-inch guns defending Singapore are left ashore because they would add an entire logistical requirement. Ammunition should also be checked. With several days of foreknowledge, available warships would be ordered to concentrate and local defence arrangements reconsidered. Fighter coordination and a larger task force are central to the wider proposal.
