On May 3, 1942 departs with British aircraft carrier HMS Eagle on another reinforcement mission to Malta. On May 9, 1942 launched her F4F Wildcats to fly a Combat Air Patrol (CAP) to protect RAF Spitfire Mark Vs flying to Malta then departed. On May 11, 1942 British Prime Minister Churchill sent a congratulatory message to Wasp: "Many thanks to you all for the timely help. Who said a wasp couldn't sting twice?"

Afterwards, returned to Norfolk Navy Yard for alterations and repairs and was to be assigned to the Pacific Fleet, following the loss of USS Lexington (CV-2) during the Battle of the Coral Sea. On May 31, 1942 assigned to Captain Forrest P. Sherman.

On June 6, 1942 departs Norfolk with Task Force 37 (TF-37) with battleship USS North Carolina (BB-55) escorted by USS Quincy (CA-39), USS San Juan (CL-54) plus six destroyers. Four days later, the group transits the Panama Canal and becomes Task Force 18 (TF-18) under the command of Rear Admiral Leigh Noyes. On June 19, 1942 arrives at San Diego and embarks carrier aircraft including TBF-1 Avengers and SBD-3 Dauntless dive bombers. On July 1, 1942 departs for Tonga escorting a convoy with the 2nd Marine Regiment.

Afterwards, Wasp with USS Saratoga (CV-3) and USS Enterprise (CV-6) were assigned to the support force under the command of Vice Admiral Frank J. Fletcher to provide aerial support for the U.S. landings at Tulagi and Guadalcanal in the Solomon Islands. Enroute on July 14, 1942 her starboard high-pressure turbine was making scraping noises and her speed was limited to 15 knots. On July 18, 1942 arrived at Tongatapu in Tonga for three days of emergency repairs and a speed test reaching 27 knots. Although replacement of the turbine blades was recommended, Wasp continued her mission. Departs bound for the Solomon Islands escorted by heavy cruisers USS San Francisco (CA-38) and USS Salt Lake City (CA-25) plus four destroyers.

On August 7, 1942 at 5:57am Wasp was in position 97 miles off Tulagi and launched her carrier planes against targets including Tulagi, Gavutu, Tanambogo, Halavo, Purvis Bay on Florida Island, Haleta, Bungana, and a radio station dubbed "Asses' Ears". Over the target, her F4F Wildcats strafed seaplanes and A6M2-N Rufe floatplane fighters moored at Tulagi Seaplane Base (Gavutu) while the SBDs bombed anti-aircraft sites and shore batteries. At 7:04am launched a second strike by twelve TBF-1 Avengers armed with bombs led by Lt. H. A. Romberg that bombed Japanese positions on Hill 281 on Tulagi. After dark, Wasp and the other carriers plus their escorts withdrew southward.

On August 8, 1942 in the morning resumed Combat Air Patrol (CAP) over the transports off Guadalcanal while a scouting force of twelve SBDs led by LtCdr E. M. Snowden flew a search of 250 miles reaching Santa Isabel Island and New Georgia Island. At 8:15am Snowden claimed a A6M2-N Rufe shot down using his nose machine guns roughly 46 miles off Rekata Bay. Meanwhile, SBDs from VS-71 led by Lt(jg) Robert L. Howard attempted to intercept incoming G4M1 Bettys attacking U.S. transports but were engaged by A6M2 Zeros. At 6:07pm Fletcher recommended to Ghormley the aircraft carriers be withdrawn and all three carriers departed.

Afterwards, Wasp conducted patrols and cover operations for convoys bound for Guadalcanal. On August 24, 1942 during the Battle of the Eastern Solomons Wasp was not in the battle area but was refueled and headed towards the action. On August 25, 1942 conducted search missions with SBD piloted by Lt. Chester V. Zalewski claimed two Jakes from Atago but failed to spot any Japanese warships as they had withdrawn. At 1:26pm launched a strike with 24 SBDs and 10 TBF against Tanaka's convoy but were unable to locate them but claimed a flying boat shot down. After the battle, only Wasp and Hornet were the only two carriers undamaged in the South Pacific.

Afterwards, USS Wasp, USS Hornet (CV-8) and USS North Carolina (BB-55) plus other warships were escorting a convoy with the U.S. Marine Corps (USMC) 7th Marine Regiment bound for Guadalcanal.

Sinking History
On September 15, 1942 at 10:00am steaming in the Coral Sea roughly 170 miles southeast of San Cristobal Island, Wasp was refueling and rearmed aircraft that had just landed. At 12:15pm, 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, at 1:50pm Japanese submarine I-19 spots Wasp and moves into position and fired six torpedoes aimed at the aircraft carrier. At 2:44pm aboard Wasp, a lookout reported "three torpedoes... three points forward of the starboard beam", with two or three exploding on impact at 2:45pm, one hit above the waterline, all in the vicinity of the fuel tanks and magazines. The other three torpedoes missed, with one hitting USS O'Brien (DD-415) and one hit USS North Carolina (BB-55). 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 dead and 366 wounded.

After the crew abandoned ship, USS Lansdowne (DD-486) was ordered to scuttled damaged Wasp, firing two torpedoes that hit but failed to explode. After firing three more that hit and exploded, Wasp remained afloat until 9:00pm when sunk at roughly Lat 12° 24′ 58″ S, Long 164° 8′ 0″ E. As the carrier sunk, Japanese submarine I-15 observed and reported the sinking.

Rescue
Afterwards, 1,946 of her crew were rescued by USS Duncan (DD-485), USS Laffey (DD-459), USS Lansdowne (DD-486), USS Helena (CL-50) and USS Salt Lake City (CA-25). All but one of her carrier planes managed to land on USS Hornet (CV-8) and were later flown to Henderson Field on Guadalcanal to operated land based.

Awards
In total, Wasp received two battle stars for her World War II service.

Shipwreck
On January 14, 2019 RV Petrel funded by Paul G. Allen discovered the shipwreck of USS Wasp at a depth of 14,255' / 4,345m upright on the bottom with parts of the hull split from the torpedo damage or when it impacted the bottom. Petrel's Remotely Operated Vehicle (ROV) documented the shipwreck including anti-aircraft guns, the bridge and carrier planes including a F4F-4 Wildcat wreckage and TBF-1 Avenger wreckage plus the bow anchor in photographs and video footage released by RV Petrel on March 13, 2019.
