The Thomas Brothers T-2 was an American-built biplane which served with the Royal Navy. Built by Thomas-Morse Aircraft in Bath, New York, in 1914, it was the creation of Benjamin D. Thomas (later the company's chief designer), based on his Curtiss JN-4 (which it resembles), and used the 90 hp (67 kW) Austro-Daimler. Twenty-four aircraft, in two batches, were provided to the Royal Naval Air Service, the Austro-Daimler being replaced by a similar-horsepower Curtiss OX-5
