Several AH-1s were deployed by the J.A.S.D.F. after Godzilla was infected by the Anti Nuclear Energy Bacteria. They fired on him using their mounted machine guns and missiles, and were backed up by a force of Mitsubishi F-15Js in an attempt to keep him within range of the M6000 T.C. System. However, none of their weaponry seemed to faze the kaiju, who proceeded to march towards a nuclear power plant. The military then had to make a hasty retreat as Biollante reappeared from space in her new form.
As Godzilla emerges from Kagoshima Bay, and walks into Kagoshima, a group of G-Force AH-1s are mobilized, and fire on Godzilla using their rockets and machine guns. The fleet of helicopters are backed up by the appearance of two DD-122 Hatsuyuki warships. Godzilla completely ignores the helicopters and then blasts the ships with his Atomic Breath, destroying them, before continuing to travel towards Fukuoka.
