Adm. Ernest (“Ernie”) King’s examination USS Independence conversion plans, January 1942

“This ship will be a most useful unit, and [her plans] are sufficiently promising to warrant immediate steps towards the conversion of two additional of this class. Examination of the prospective dates of completion of the 10,000-ton cruisers…indicates that it would be practicable to select two for conversion now which could be completed at approximately the same time as the Amsterdam. It is further considered that there are sufficient cruisers of this type under construction to warrant Photo: National Archives conversion of two more ships to aircraft carriers. If the decision is made now the very desirable result USS Independence (CVL 22) received eight battle stars will be the completion of three small aircraft carriers at about the end of the year 1942, instead of one due to the heroic actions of the Sailors and Officers, Pilots as now planned.” Friedman, N., U.S Aircraft Carriers: An Illustrated Design History and Marines that served aboard the carrier in WWII. http://farallones.noaa.gov/welcome.html damaging a cruiser in the “Battle of the The second test, code name “Baker,” was Independence now rest in the northern Sibuyan Sea.” Returning to night an underwater detonation 1390 yards from region of Monterey Bay National Marine operations, search planes located and the carrier.
