paragraph_text: Iwo Jima remained off Quinohn for defensive support until 20 July 1965, then steamed for Pratas Reef about 240 miles southwest of Taiwan. Arriving the morning of the 22d her helicopters were immediately pressed into service to aid the salvage of destroyer Frank Knox (DD-742). The close approach of typhoon "Gilda" pounded the grounded destroyer so badly that it was impossible for small boats to get alongside her. Extra men were heli-lifted off the destroyer while surf rose 12 feet high to break completely over the stern of Frank Knox. Support given by Iwo Jima included such items as hot food, clothes, water, pumps, hose, gasoline, air compressors, welding machines, damage control equipment and technicians. Feed water was heli-lifted in special tanks constructed by destroyer tender Prairie (AD-15) who had faint hope of keeping the destroyer's boiler alive. Detached from this duty 1 August 1965, Iwo Jima made a brief call at Hong Kong, then proceeded to the Philippines.
