The Air Staff wanted a day bomber capable of exceeding 160 miles per hour, a requirement many manufacturers considered difficult to meet. The competitors included the Avro Antelope, de Havilland Hound, Fairey Fox, and Hawker Hart. Their quoted performance figures differ substantially: the Fox reached 189 miles per hour at 16,400 feet, while the Hound managed 153 miles per hour at 6,500 feet. The Antelope reached 173 miles per hour, although its test altitude is unspecified. The Hart ultimately proved better than its competitors and received its production order under a later specification.
