Question: The Curtiss F7C Seahawk was a biplane that could be landed on which type of capital ship?
Context: The Rex Smith Biplane was a pioneering biplane based mostly on designs of Glen Curtiss.  It was built and demonstrated at College Park, Maryland at the same airfield that the Wright Brothers trained pilots using their aircraft for the U.S. Army Signal Corps just North of Washington D.C.  This followed the initial demonstration at Fort Myer, Virginia in 1908 and 1909 when the U.S. Army Signal Corps accepted the Wright Flyer in July, 1909.  Both the Wright Brothers and Curtiss continued to demonstrate their aircraft at the College Park Airport. Abdül Kadir was a pre-dreadnought battleship laid down in 1892 at the Constantinople imperial dockyard for the Ottoman Navy, the first vessel of this type to be ordered by the Ottoman Empire.  The ship was the first capital ship to be laid down by the Ottomans in more than a decade.  She was to have a main armament of four 28 cm guns, with an armoured belt that was 230 mm thick.  Work proceeded on the ship very slowly, primarily the result of a lack of funds; after two years, only the frames for the hull had been erected, and by the time work stopped in 1906, the hull had been only partially plated.  The unfinished ship was ultimately broken up for scrap in 1909. An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft.  Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations.  Aircraft carriers are expensive to build and are critical assets.  Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighter planes, strike aircraft, helicopters, and other types of aircraft.  While it is possible to launch heavier aircraft such as fixed-wing gunships and bombers (it has been done) from aircraft carriers, it is virtually impossible to land them. The Curtiss F7C Seahawk was a carrier-capable biplane fighter aircraft of the United States Navy Marine Corps in the late 1920s and early 1930s. The Curtiss No. 2, often known as the Reims Racer, was a racing aircraft built in the United States by Glenn Curtiss in 1909 to contest the Gordon Bennett Cup air race in Reims, France that year.  It was a modified Golden Flyer, and was an open-framework biplane with two-bay unstaggered wings of equal span.  It had a monoplane tail that controlled the rudder but the elevators were carried forward of the pilot as a biplane canard unit.  The landing gear was wheeled and tricycle in configuration, with each unit carrying a single wheel.  Large ailerons were carried in the interplane gap.  Curtiss modified the Golden Flyer into the Reims Racer by adding a covered stabilizer unit at the canard, increasing the wing size, modifying the interplane elevators and replacing the four cylinder inline Curtiss OX engine with that of a Curtiss OX V8 that had been stripped down and specially lightened for the race.  A new, lighter fuel tank was exchanged for the older, heavier one. The Curtiss F6C Hawk was a late 1920s American naval biplane fighter aircraft.  It was part of the long line of Curtiss Hawk airplanes built by the Curtiss Aeroplane and Motor Company for the American military. SMS "Hindenburg" was a battlecruiser of the German "Kaiserliche Marine" (Imperial Navy), the third ship of the "Derfflinger" class , built to a slightly modified design.  She carried the same battery of eight 30.5 cm guns, but in improved turrets that allowed them to fire further.  The ship was also slightly larger and faster than her two sister ships.  She was named in honor of Field Marshal Paul von Hindenburg, the victor of the Battle of Tannenberg and the Battle of the Masurian Lakes, as well as Supreme Commander of the German armies from 1916.  The ship was the last capital ship of any type built for the German navy during World War I. The Curtiss Fledgling, known internally to Curtiss as the Model 48 and Model 51 was a trainer aircraft developed for the United States Navy in the late 1920s and known in that service as the N2C.  It was designed in response to a 1927 Navy requirement for a new primary trainer, and was selected after evaluation in competition with fourteen other submissions.  The Fledgling was a conventional biplane design with two-bay, staggered wings of equal span braced with N-struts.  The pilot and instructor sat in tandem, open cockpits, and the fixed tailskid undercarriage could be easily swapped for a large central pontoon and outrigger floats under the wings for seaplane training.  The Navy ordered two batches of the Fledgling, each powered by different versions of the Wright Whirlwind engine, both of which were built under the Curtiss designation Model 48. The Curtiss SO3C Seamew was developed by the Curtiss-Wright Corporation as a replacement for the SOC Seagull as the United States Navy's standard floatplane scout.  Curtiss named the SO3C the "Seamew" but in 1941 the US Navy began calling it by the name "Seagull", the same name as the aircraft it replaced (the Curtiss SOC a biplane type), causing some confusion.  The British Royal Navy kept the Curtiss name, ("Seamew"), for the SO3C that they ordered.  One of the US Navy's main design requirements was that the SOC Seagull's replacement had to be able to operate both from ocean vessels with a single center float and from land bases with the float replaced by a wheeled landing gear. The Curtiss SC Seahawk was a scout seaplane designed by the Curtiss Aeroplane and Motor Company for the United States Navy.  The existing Curtiss SO3C Seamew and the Vought OS2U Kingfisher were 1937 designs that, by 1942, needed to be replaced.
