Hanging overhead is the Hanriot HD-1. A capable French fighter, the HD-1 was overshadowed by its contemporary, the SPAD VII, and saw use mostly with Belgian and Italian pilots. After the war, the U.S. Navy acquired several for shipboard evaluation, performing launch experiments from wooden decks erected atop the gun turrets of battleships. Though this method was ultimately abandoned, it was nonetheless part of a movement to make Naval Aviation a force firmly integrated with the surface fleet.

The first aircraft produced by Hanriot-Dupont, a company formed at the beginning of World War I, the HD-1 appeared around the same time as the highly capable SPAD VII. Thus, though over 1,000 HD-1s were built, they did not see widespread service with the French, instead flying in the hands of Belgian and Italian pilots. One of the former, Willy Coppen, achieved a string of victories in the nimble fighter, while Italian HD-1s shot down eleven German fighters without losing one of their own during the Battle of Istrana on 26 December 1917.

While the HD-1 achieved combat success over European battlefields, U.S. Navy officers at sea witnessed firsthand the tremendous strides made by the British Royal Navy in operating aircraft from ships during World War I. This prompted these air-minded officers to evaluate shipboard operations in the months following the end of the Great War. Realizing that wheeled-aircraft provided more capability in speed and maneuverability, the Navy procured a handful of foreign-built aircraft for use in the experiments, flying them from wooden decks erected atop the gun turrets of battleships. Among them were the Hanriot fighters.

Out of a batch of 26 French Hanriot HD-2 seaplanes, the Navy converted ten to landplane configuration and designated them HD-1s. Some outfitted the Ship Plane Unit conducting experimental work at Langley Field, Virginia, and others operated from the battleship Mississippi(BB-41) under the command of Captain William A. Moffett, who later was promoted to flag rank and became the first Chief of the Bureau of Aeronautics. Given their operations over water, the HD-1s were equipped with flotation bags beneath the wings that could be inflated in the event of a water landing as well as a hydrovane forward of the main landing gear to prevent the aircraft from nosing over when it hit the water. Hanriots remained in the Navy's aircraft inventory into the early-1920s.

A modified version of Glenn Curtiss' widely used F-Boat, the MF-Boat was built as a trainer and support aircraft. Serving throughout World War I, F and MF-Boats prepared Naval Aviators for their primary mission of anti-submarine warfare over the Atlantic, protecting Allied shipping from the dreaded U-boat. The Museum's aircraft is a rare example and the first of 80 MF-Boats built at the Naval Aircraft Factory.

Following his successful demonstration of a hydroaeroplane, which the Navy procured as its first aircraft in 1911, aircraft manufacturer Glenn Curtiss shifted his design ingenuity to the development of a true flying boat. Numerous experimental designs culminated in the introduction of the C-boats (later designated AB-1/5), a class of flying boat that made notable contributions to the history of U.S. Naval Aviation. As a successor to the ABs, the Navy procured some 144 F-Boats and 102 MF-Boats, the MF meaning "Modified F."

Both Curtiss and the Naval Aircraft Factory built MF-Boats. Designed to serve as trainers, the MFs differed from F-Boats structurally, namely in the sponsons jutting out from the hull in order to impart stability on the water. MFs served in a variety of roles, supporting the newly formed Fleet Air Detachment during operations in the Atlantic Ocean, and operating at most of the Navy's air stations in the immediate postwar years. Standard arrangement allowed for side-by-side seating for instructor and student, with the pusher engine (the propeller facing aft) located above and behind the cockpit.

Even though Curtiss had ceased production of the MF-Boat for the Navy in the months following World War I, the company had not given up on the design, marketing it as the "Seagull" and offering it to civilian buyers beginning in March 1919. With the successful flight of the NC-4 across the Atlantic two months later igniting an interest in seaplanes, Curtiss even began to market the Seagull as a way for people to have an NC of their own. Ironically, the NC-4's co-pilot, Lieutenant Junior Grade Walter Hinton, was one of the customers who operated a Seagull. Hinton flew one Seagull christened Eleanor III during the Rice Expedition of 1924–1925, logging 12,000 miles in a harsh jungle environment in the survey of the headwaters of the Amazon River. A number of Seagulls operated as some of the first commercial passenger aircraft, providing service between Catalina Island and Los Angeles and over Atlantic City.

The Museum's aircraft (Bureau Number A-5483) was the first of eighty MF-Boats built at the Naval Aircraft Factory in 1918, and served until 1922, at which time it was sold to Harry Dallas of Auburn, Massachusetts. The following year Eupilio Andreatto purchased the aircraft. A veteran of service in the Italian Air Force during World War I, Andreatto flew the aircraft on aerial tours of Atlantic City, New Jersey, during the summers (charging $5 per ride) and stored it at the Philadelphia Seaplane Base at Essington, Pennsylvania, during the winter months. The aircraft's last flight came in 1936 from the Philadelphia Seaplane Base with Frank Mills (the base's proprietor) and Albert J. Sidlow at the controls. The aircraft was stored in a garage until acquired by Mr. George S. Waltman around 1960. Purchased by the Navy, the airplane was ironically restored at the former site of the Naval Aircraft Factory in which it had been built. It arrived at the Museum in 1968.
