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.
