British Pacific Fleet particularly the capital ships (A comparison of HMS "King George V" and USS "Washington" conducted in 1942 found the British ship burned 39% more fuel at cruising speed and 20% at high speed, giving her half the action radius.) British ships therefore required replenishment more frequently than American ships. In some cases even American-built equipment was not interchangeable, for FAA aircraft had been "Anglicized" by the installation of British radios and oxygen masks, while Vought Corsairs had their wing-folding arrangements modified to fit into the more cramped hangars of British carriers. Replacement aircraft therefore had to be brought from the
