You need Fortress Penang Island, 210 miles away from the landing beaches by air, you need radar there, an Observer Corps forwards of it. Hurricane IIa's for air defence, Hurricane IIb's with drop tanks for long range escort, Hurricane IIc's with long range tanks for strafing the beaches and HP Hampdens equipped with torpedoes, mines, bombs. They're capable of dive bombing and have a max range of 2000 miles. By all means base the Catalinas on the East Coast to patrol the South China Sea. But remember, you cannot lose Penang, after that it's game over. Throw in some Harrows and/or Bombays for resupply and medivac of your troops defending Kota Bharu. Worse case scenario there is an orderly retreat down the railway line to Kuala Lumpur which must be held. You're going to have to hold onto Port Blair in the Southern Andaman Islands too as its an essential staging Post for reinforcements from India and Ceylon. Maybe we need to have some old WW1 battleships moored in harbours for defence too. If we lose either Penang or Port Blair it's game over in the defence of Malaya. In the case of Burma, we can simply retreat and over extend the Japanese supply line.Whilst a 1945 trained army with 1841 weapons could have been a bad thing for the Japanese the Japanese army was at it's most vulnerable at sea approaching Malaya. Anything that can strike the troopships before they land their troops and/or return for more will have more impact that the same resources deployed on land. It may be cool to picture carriers steaming to launch decisive air strikes but this is not the deep Pacific. It is a (very large) coastline open only to the east. Land based maritime strike is a better choice. What carriers can do is appear with a air strike capacity where land based aeroplanes cannot. A squadron of Bostons for example, will deliver far more bang than a carrier squadron and has the fuel and bombs to maintain action over weeks without steaming away to refuel and rearm in a port days away. In 1941 one might have (War Cabinet willing)

All of which need fighter cover. It is said that bombs let in air but torpedos let in water which is a correct view of attacking warships with armour and damage control. But troopships are unarmoured and vulnerable to fires and damage control is hard. To strike at the naval vessels torpedos are the answer but bombs at low level by trained aircrew will do very nicely for the troopships. If you want torpedoes then you have to look at the spare FAA resources additionally to the above to whit

These will not live in a defended environment no matter how brave the crews but can operate at night by moonlight or flares.
Not normally mentioned when defending Malaya is spoken of is that Burma was being invaded at more or less the same time by land across northern Thailand eve if you hold Malaya.
