Robert F. Dorr (September 11, 1939 – June 12, 2016) was an American author and retired senior diplomat who wrote and published over 70 books, hundreds of short stories, and numerous contemporary non-fiction articles on international affairs, military issues, and the Vietnam War.

He headed the weekly "Back Talk" opinion column for the Military Times newspaper and the monthly "Washington Watch" feature of Aerospace America.

Dorr was fluent in French, Japanese, Korean, Russian, Swedish, and German, and retired as a Senior Foreign Service officer in 1990.

It is a history of an aerial band of brothers who went ashore at Normandy just after the June 6, 1944 D-Day invasion, fought on the continent through the Battle of the Bulge, and were still in action when Germany surrendered.

These American airmen lived under crude conditions, and were subject to harsh weather and frequent enemy attacks as they moved from one airbase to another, accompanying the Allied advance toward Germany.

The Experimental Aircraft Association's Warbirds magazine (July 2008) wrote, "Hell Hawks is a Stephen Ambrose-style history of a 'band of brothers' with airplanes."

Walter J. Boyne wrote, "Mission to Tokyo is yet another incredible solo example of Bob's prolific scholarship and dedication to the art of writing aviation history.

[11] Dorr's book Mission to Berlin, about the Eighth Air Force raid of February 3, 1945 over Europe in World War II, was published May 1, 2011.

This is primarily a history of B-17 Flying Fortress crews in one of the largest air battles of the war but it also covers Americans who flew and maintained the B-24 Liberator, P-47 Thunderbolt, and P-51 Mustang.

The novel centers around competing groups of American and German scientists trying to perfect a working time machine in order to influence the outcome of World War II.
