The Howard DGA-6 was a pioneer racing plane, nicknamed "Mister Mulligan". It was the only airplane ever designed for the specific purpose of winning the Bendix Trophy. The plane was designed and developed by Ben Howard and Gordon Israel, who later became an engineer for the Grumman Aircraft Engineering Corporation. Mister Mulligan was designed to fly the entire length of the race nonstop and at high altitude. Neither had ever been done before. Mister Mulligan won the trophy, and thus changed the way in which long distance airplanes were designed.

It was sold in North America as the Fokker F-11 and was offered in Europe as the Fokker B.IV. By the time the first six aircraft had been constructed, it was already evident that the design was not going to sell well. A few were sold, two to notable multi-millionaires; Harold Vanderbilt and Garfield Wood each purchasing one. One was bought by Air Ferries in San Francisco. The F-11A cost $40,000 but the price was slashed to $32,500 as the depression set in during 1930. The F-11 was a commercial failure.
