The United States commissioned it's first CVE, the USS Long Island, before the British commissioned theirs, HMS Audacity. Still, there were some problems with the first US/UK CVEs based on the diesel driven C-3 merchants. The ships were being produced by Sun Shipbuilding, which had not yet been configured for mass-production shipbuilding. Also, the diesels were not performing as reliably as expected. These lead to a switch to steam turbine merchants being produced by Ingalls and Seattle-Tacoma, both were geared for mass production. The US Navy was also considering converting several fast passenger liners into aircraft carriers, but this was cancelled at the end of 1941.
