Bill Gunston was a British aviation and military author. He flew with Britain's Royal Air Force from 1945 to 1948, and after pilot training became a flying instructor. He spent most of his adult life doing research and writing on aircraft and aviation. He was the author of over 350 books and articles. His work included many books published by Salamander Books.
1983 is a long time ago in terms of aircraft design and technology. This book is still great though, it goes into a level of detail that is rarely seen without getting bogged down in equations. Highly recommended.
Read this long ago, its an excellent primer on various issues in modern aerial combat and how guided missiles and smart weapons work. A little dated by now but still useful.
