Air Group NINETEEN was established on 15 August 1943, consisting of VF-19 (Fighting), VB-19 (Bombing) and VT-19 (Torpedo). Initially stationed at Los Alamitos where it started to receive it's aircraft, the Grumman F6F-3 Hellcat, along with SBD-5 for VB-19 and TBM-1 for VT-19.
Aboard the USS Lexington (CV-16), NINETEEN saw it's first action the Battle for Leyte Gulf, the climactic American naval victory over Japan. While the carrier came under constant enemy attack in the engagement in which USS Princeton (CVL 23) was sunk, her planes joined in sinking Japan's super-battleship Musashi and scored hits on three cruisers 24 October 1944. Next day, with Essex aircraft, they sank carrier Chitose, and alone sank Zuikako. Later in the day, they aided in sinking a third carrier, Zuiho. As the retiring Japanese were pursued, her planes sank heavy cruiser Nachi with four torpedo hits 5 November off Luzon.

During the action, the Lexington lost her island structure to a kamikaze plane. Within 20 minutes mayor blazes were under control, and she was able to continue normal flight actions, her guns knocking down a would-be kamikaze heading for the carrier USS Ticonderoga (CV-14) as well. On 9 November Lexington arrived Ulithi to repair battle damage and learn that Tokyo once again claimed her destroyed.
