In The Sikorsky HH-52A, noted historian Lennart Lundh presents this diminutive helicopter's story for the first time. Covered are design details, international service, licensed production by Mitsubishi, and the story of the "Seaguard's" use by the U.S. Coast Guard. A record of each airframe's history is included, as are photographs of three-quarters of the S-62As, S-62Js, and HH-52As produced. Of special interest are the recollections of nearly a score of Coast Guard pilots and aircrew, and the text of the Army's evaluation of the first production airframe. AUTHOR:.
