Torpedo Squadron Eleven (VT-11) was established at Naval Air Station San Diego on 10 October 1942, flying TBF Avengers.
Over the next five years, the squadron upgraded through several models of TBF and TBM Avengers.

On 25 April 1943, VT-11 arrived at Guadalcanal.
The squadron's first combat was flown from Henderson Field as part of Carrier Air Group Eleven (CVG-11).
The squadron was land-based at Guadalcanal, and in June 1943, VT-11 pilots conducted the first daylight raids on Bougainville and the Solomon Islands.
They flew patrol, search, spotting, strike, and night mine-laying missions.

From 29 September 1944 to 1 February 1945, VT-11 was deployed aboard USS Hornet.
The squadron participated in the first strikes against Okinawa and two weeks later converged on Leyte Gulf to protect the landing and supply ships engaged in the Battle of Leyte.
On 25 October, the Japanese Fleet converged on Leyte to oppose the landings.
Squadron TBMs were launched from 550 km (342 mi) away (well beyond normal range) to strike the fleet.
The TBMs struck the retiring Japanese ships, scoring hits on a battleship and two cruisers.
All the squadron's aircraft returned, completing a 1,000 km (621 mi) round trip.
Seven Navy Crosses were awarded to VT-11 aircrews during this campaign.

In November and December 1944, the squadron continued to provide support for the occupation of Leyte, striking targets on Luzon in support of the landings on Mindoro.
In January 1945, the squadron struck ships and targets on Formosa and Luzon in support of the Invasion of Lingayen Gulf, Luzon.
The squadron participated in operations in the South China Sea (the first time an American Task Force had entered these waters since the beginning of the war), striking targets at Cam Ranh Bay and a convoy off Qui Nhơn, French Indo-China, shipping at the Pescadores Island, and Hong Kong.

An exhibit honoring VT-11 during World War II is on board the USS Hornet Museum in Alameda, California.

After the war, Naval Air Station San Diego became VT-11's new homeport, and the squadron was redesignated as Attack Squadron 12A (VA-12A) in November 1946.
VA-12A, along with Carrier Air Group (CVAG-11), underwent extensive training and embarked on USS Valley Forge, the U.S. Navy's newest aircraft carrier.
In June 1948, VA-12A deployed on a world cruise, a first for a U.S. Navy air group and milestone for the squadron.
A symbolic globe later became part of the squadron's official insignia to commemorate the cruise.

On 15 July 1948, VA-12A was re-designated Attack Squadron 115 (VA-115), and in December, the squadron transitioned to the AD Skyraider, operating several improved models over the next ten years.
