USS St. Lo (CVE-63) was a Casablanca-class escort carrier of the US Navy. Launched on 17 August 1943 and commissioned on 23 October 1943 as USS Midway (CVE-63). She was renamed St. Lo on 18 July 1944 to free up the name for a new attack aircraft carrier.
During the Battle off Samar, St. Lo came under fire from Japanese battleships and cruisers. Returning fire with her single five- inch gun, she claimed three hits on a Japanese cruiser.
The Japanese surface force retired at 9:20 only to be replaced by kamikaze attacks at 10:50. St. Lo was struck by a Mitsubishi A6M Zero. Its bomb penetrated the flight deck and started a gasoline fire in the hanger. This ignited bombs and torpedoes being loaded onto aircraft followed by the detonation of the ship’s magazine.
Of the 889 man crew 113 were killed or missing with an additional 30 dying of their wounds.
