Sinking History
On September 15, 1942 USS Hornet, USS Wasp and USS North Carolina (BB-55) plus ten other warships plus transports carrying the U. S. Marine Corps (USMC) 7th Marine Regiment bound for Guadalcanal.

By 10:00 the carrier while operating 170 miles southeast of San Cristobal Island, Wasp was refueling and rearmed aircraft that had just landed. At 12:15, a F4F Wildcat from Wasp claimed a Japanese four engined flying boat shot down. At 2:20pm, Wasp launched eight F4F Wildcats and eighteen SBD Dauntless dive bombers and successfully recovered eight Wildcats and three SBD Dauntless.

Meanwhile, Japanese submarine I-19 fired a spread of six torpedoes at Wasp. At 2:44pm a lookout reported "three torpedoes ... three points forward of the starboard beam", each impacted around 2:45pm, one hit above the waterline, all in the vicinity of the carrier's gasoline tanks and magazines. The other three missed with one hitting USS O'Brien DD-415 and one hitting USS North Carolina. Escorting destroyers dropped 80 depth charges by Japanese submarine I-19 escaped safely.

Explosions erupted in the forward part of the carrier, causing aircraft to drop onto the flight deck and fall out of storage. Fires began in the hanger below deck and caused ammunition to explode and the 1.1" AA gun mount (No. 2) was blown overboard by the explosion. Water mains were inoperable and the fire and the carrier listed to 10° to 15° starboard and a fuel slick caught fire on the sea. The flames spread and caused additional explosions and all communication went dead. At 3:20pm Captain Sherman order the crew to abandon ship, the survivors exited the ship into life rafts. Aboard, 45 aircraft were lost with the carrier. In total, 193 men died and 366 were wounded during the attack.

After the crew abandoned ship, USS Lansdowne DD-486 was ordered sink Wasp, firing two torpedoes that hit but failed to explode. After firing three more that exploded Wasp remained afloat until 9:00pm before sinking at roughly Lat 12° 24′ 58″ S, Long 164° 8′ 0″ E. Japanese submarine I-15 observed and reported the sinking of the Wasp. In total, Wasp received two battle stars for her World War II service.

Afterwards, USS Laffey DD-459, USS Lansdowne DD-486, USS Helena CL-50 and USS Salt Lake City CA-25 rescued 1,946 of her crew. All but one of her aircraft landed on USS Hornet CV-8 and were later flew to Henderson Field on Guadalcanal to operated land based.
