This book features a really close look at a versatile helicopter that was designed for an anti-submarine role, but later also used as a search-and-rescue helicopter, for troop transport, and as an EAW-helicopter. No detail is overlooked and both the Sikorsky-built and Westland-built machines are included. Separate chapters include the RAF and FAA versions, the German and Norwegian versions, the Blegian Mk.48, Spanish SH-3D, and much more. Even a marine helicopter is shown up-close. Sea Kings from many countries are included: Egypt, India, Japan, Canada, Denmark, etc. This book also includes one of the most extensive maintenance chapters done thus far in this series, illustrating engines, avionics, main rotor gearboxes, spines, tail folding systems, and more.
