The squadron was critical in the testing of the AIM-260 JATM long range air-to-air missile. In 2024, "The Dust Devils" heavily contributed to the testing of the AIM-174B air-to-air missile as well.^[1]

In 2025, the squadron retired the AV-8B Harrier II from service, marking the last use of the jet from the Navy.^[2]
