Carrier Air Group Six then embarked on board the new "Essex"-class aircraft carrier to provide air support for the amphibious landings on Kwajalein Atoll from 31 January to 3 February 1944. They also participated in a massive air strike against the Japanese naval base at Truk. The air group destroyed fifty-five enemy planes (twelve in the air and forty-two on the ground) as well as sinking five Japanese ships. Nine planes were lost, with nine pilots and four crewmen dead or missing.
