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
HMS Prince Regent (1814) private contract. Shortages of men and material at the shipyard led to construction delays. By January 1814, the frigate was completely planked and by February, had been caulked. "Prince Regent" was launched on 14 April 1814, a half hour after , the other frigate under construction. "Prince Regent" was made the flagship of Commodore Sir James Lucas Yeo's British squadron on Lake Ontario. Commander Richard O'Connor was advanced to the rank of post-captain and made Yeo's flag captain aboard "Prince Regent". The squadron departed Kingston on 4 May with infantry and Royal Marines embarked for an attack on Fort Oswego.
