Swett returned to Guadalcanal after a short stay in a Naval hospital and learned that Admiral Marc Mitscher had nominated him for the Medal of Honor. After a short rest in Australia, Swett checked out in the Vought F4U Corsair to which VMF-221 was converting and moved to a new base in the Russells. Promoted to captain, Swett covered the Rendova landings on June 30, 1943, adding two Mitsubishi G4M "Betty" medium bombers to his score and sharing the downing of a Mitsubishi A6M Zero.
