The AA crews of the Battleship HMS Prince of Wales and battlecruiser HMS Repulse were shocked and stunned by the speed and performance of the Japanese torpedo bombers which attacked and sank them on 10 December 1941 off the coast of Malaya.
Japanese aircraft were state of the art in 1941, and more than a match for the allied aircraft sent against them. Thankfully they were generally unable to improve their machines very much during the war while the USA was able to take military aviation to a new level.
However, irrespective of the technology, an aircraft is only as good as it's pilot, and the Japanese pilots were superb.
Had the RAF in Malaya been equipped with Spitfire's instead of Brewster Buffalo's maybe things might have turned out differently.
