I was not familiar with this series of books, so I was not sure what to expect. But being a fan of British aircraft, I couldn’t pass up the chance to review it. This book by author Chris Goss is just under 100 pages and measures 9.5” tall and 6.75” wide. There is a short forward by Air Marshal Philip Sturley and a one page introduction by the author. All of the photographs are from the collection of the late David Howley. The book contains one chapter covering the Jaguar and another covering the Harrier. There is also a short appendix listing the different variants of the two aircraft and units that operated them. The pictures are a mixture of black and white photos and color photos and are presented two on a page for the majority of the book.

The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs, or "dumb bombs", into all-weather precision-guided munitions. JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles. JDAM-equipped bombs range from 500 to 2,000 pounds . The JDAM's guidance system was jointly developed by the United States Air Force and United States Navy, hence the "joint" in JDAM. When installed on a bomb, the JDAM kit is given a GBU (Guided Bomb Unit) identifier, superseding the Mark 80 or BLU (Bomb, Live Unit) nomenclature of the bomb to which it is attached.
