Metz, Paul Northrop F-20 Tigersharp

This book traces the development of the 3 generations of a 1955 design called the N-156 which became the T-38 and the F-5A/B. The F-5A/B evolved into the F-5E/F and finally the F-20 Tigershark. Each step in that progression was to keep up with the latest Soviet fighters. The F-20 was designed to counter the Mig-29 and Su-27, 4th generation fighters. The book reveals the unique design goals that produced a reliable, easily maintained, easy to fly, agile fighter-bomber that was affordable for many allied air forces in the wake of WW II. The story is told from the first person accounts ("Tigershark Voices") of the struggles and triumphs to create a new type of fighter in a world of increasingly complex, expensive and maintenance-intensive fighters. Other "Tigershark Voices" bring the reader into the F-5 and F-20 cockpits as the pilots describe flying this breed of fighters.
This definitive Tigershark book features original documents and photographs, most in color and previously unpublished. Original documents of USAF struggles to name the Tigershark the F-20, Presidential directives to build a fighter for export and limitations on sales, performance with no government funding are a few of the many examples of original documents pivotal to the F-20 story.
Also included are the various F-20 follow-on proposals: RF-20A/B, F-20B/C/E/F and Lavi fighters. As with all Ginter books, the F-20 Tigershark also presents information of interest to the scale modeler.

Beyond the detailed color photos, the book has many detailed factory drawings of the F-5 and F-20 with 3-views, cross section cuts and inboard drawings showing structure and equipment in great detail. The cockpit comparison drawings are masterpieces of the graphic arts.
