VA-34 (1943–1969)

VF-20 "Jokers" was established on 15 October 1943 as part of Air Group 20 stationed at Naval Air Station San Diego, California. The squadron was composed of numerous newly winged Naval Aviators along with a few combat veterans. On 16 April 1944 the squadron departed Naval Air Station Alameda aboard USS Essex en route to Hawaii for four months of operational training prior to its first combat tour.

On 31 August 1944, the squadron's first combat action came as combat strikes were flown from USS Enterprise (CV-6) in squadron F6F Hellcats against the Bonin Islands. Strikes followed to Yap and Palau Islands, Peleliu Island, Okinawa, Formosa, Luzon, and Leyte. VF-20 was heavily involved in the initial invasion operations in the Philippines, including the epic Battle of Leyte Gulf from 24–25 October 1944. VF-20 aircraft struck elements of all three Japanese Task Forces which were converging on Leyte Gulf.

On 11 December 1944, VF-20 cross-decked to the USS Lexington

On 14 December 1944, Lieutenant (junior grade) Douglas Baker was on a strike mission against Clark Field on Luzon when he encountered Japanese fighter opposition. During this engagement he destroyed four Japanese aircraft before being shot down by antiaircraft fire and lost in the action. This final action brought his air-to-air kills to 16, making him one of the high ranking aces for the Navy. Only eight other Navy pilots equaled or exceeded this record.

From December 1944 to January 1945, VF-20 engaged in another series of combat actions, flying missions against targets on and around Luzon, Formosa, French Indochina (Vietnam), Hong Kong, the South China Sea, and Okinawa. Many of these operations were in support of the landings at Lingayen Gulf.

As part of Admiral Halsey's Northern Strike Group, VF-20 assisted in sinking one of the world's largest battleships, the Japanese battleship Musashi (sister ship to the Yamato), and was given credit for partial kills on several Japanese cruisers and destroyers.

22 January 1945 was the last day of combat action for the squadron during World War II. In February 1945 the Jokers embarked on USS Kwajalein at Ulithi and departed for the United States, arriving there in the latter part of the month.

During WWII, eight VF-20 pilots became aces, 12 pilots received the Navy Cross and 22 received the Silver Star. VF-20 was credited with the destruction of over 15 ships and 407 aircraft, not counting the even greater number that were damaged but not destroyed. For their combat efforts the command was awarded the Presidential Unit Citation in 1944 and 1945, along with the Navy Unit Citation while aboard Enterprise.

In April 1946, the squadron transitioned to the F8F Bearcat.

From July to September 1948, in cooperation with Commander Operational Development Force, Atlantic Fleet, the squadron participated in the experimental carrier controlled approach program aboard the USS Philippine Sea.

In November 1950, VF-34 transitioned to its first jet aircraft, the F9F Panther.

After returning from a cruise aboard USS Leyte in December 1951, the unit transferred to NAS Cecil Field, Florida.

In February 1952, the squadron began initial training in the F2H Banshee

In April 1953 the squadron embarked on USS Antietam with its F2H-2s to conduct evaluation tests on the Navy's angled deck.

On 26 May 1954 the squadron was aboard USS Bennington, en route to the Mediterranean Sea, when an explosion aboard ship resulted in the death of 7 squadron personnel. The ship returned to the States and the squadron disembarked.

On 31 October 1954 Ensign Duane L. Varner completed a 1,900 mile nonstop, non-refueling, transcontinental flight from Los Alamitos, California, to NAS Cecil Field in a squadron F2H-2. His flight took 3 hours and 58 minutes and set a new long distance record for the Banshee.

In early 1956, VA-34 accepted its first F7U Cutlass, which it operated until receiving A-4 Skyhawks in March 1957. The squadron was the first Skyhawk squadron to deploy to the Mediterranean.

On 4 March 1958 during cross-deck operations, the squadron landed its A4D-1 Skyhawks aboard HMS Ark Royal.

In July 1958, VA-34 flew support missions during the amphibious landings in Beirut, Lebanon, by U.S. Marines.

In June 1959, whilst operating from NAS Mayport, the squadron conducted the first operational firing of the Bullpup air-to-ground missile in the Atlantic Fleet.

From 1959 through 1966, the Blue Blasters operated from the decks of USS Saratoga (CVA-60) and USS Essex (CV-9).

In April 1961, VA-34's A4D-2 Skyhawks operated from USS Essex in the Caribbean Sea during the Bay of Pigs invasion. This operation involved the first use of jet attack aircraft as part of an ASW Air Group, CVSG-60, operating aboard an ASW designated carrier.

From 26 October to 8 November 1962 during the Cuban Missile Crisis, the entire squadron flew aboard USS Enterprise to augment the assigned air wing. VA-34 flew numerous missions in support of Cuban quarantine, later transferring to USS Independence until her return to the United States on 26 November.

From 3–21 December 1962 the squadron was aboard USS Saratoga for carrier refresher training in the Caribbean and continued operations relating to the Cuban Missile Crisis.

From December 1963 to February 1964 the squadron provided detachments of A-4C Skyhawks aboard USS Intrepid and USS Randolph. The aircraft were used for Combat Air Patrol to provide a fighter capability for the ASW carriers.

From May to December 1967, the squadron deployed to the Gulf of Tonkin during the Vietnam War aboard USS Intrepid. This was the squadron's first combat action since 1945.

Attack Squadron 34 was disestablished on 29 May 1969.[1]^: 37
