The Fokker T.IV was a Dutch torpedo bomber/maritime reconnaissance floatplane of the 1920s and 1930s. First flying in 1927, it served with the Dutch Naval Aviation Service in the Dutch East Indies until the remaining aircraft were destroyed during the Japanese invasion in 1942.
The Fokker T.IV was developed to meet the requirements of the Royal Netherlands Navy for a maritime patrol/torpedo bomber aircraft for use in the Dutch East Indies. First flying on June 7, 1927, [1] the T.IV was a twin engined floatplane with a thick, cantilever, high mounted monoplane wing and a deep, slab-sided fuselage with an open cockpit housing the two-man crew. The aircraft could carry either a torpedo or 800 kg (1,764 lb) of bombs, and had a defensive armament of three machine guns in nose, dorsal and ventral positions, The initial version was powered by two 450 hp (340 kW) Lorraine-Dietrich 12E W-12 engines.
In 1935, Fokker produced a developed version, the T-IVa, to supplement the existing T-IVs in Dutch service. Wright Cyclone radial engines replaced the Lorraine Dietriches, while the pilots were provided with an enclosed cockpit in a hump over the wing root, and enclosed nose and dorsal gun turrets were fitted. [2] 12 were built for the Dutch Naval Aviation Service, while the remaining T-IVs were rebuilt to the T-IVa standard. [2]
Deliveries of the original T.IV to the Dutch Naval Aviation Service in the Dutch East Indies started in 1927 and continued until 1930. [3] The second batch of 12 TIVa aircraft was delivered to the East Indies from 1936 to 1938, [3] and the original T.IVs were rebuilt as T.IVas. [4]
The T.IV proved to be a reliable and seaworthy aircraft, [5] and continued in use for local patrols and air-sea rescue operations from the naval base at Soerabaja on Java until 1942, when the Japanese attacked the Dutch East Indies. [6] All the remaining TIVs were destroyed during the Japanese invasion, either by Japanese bombing or scuttling. [3] [6]

The Vought OS2U Kingfisher is an American catapult-launched observation floatplane. It was a compact mid-wing monoplane, with a large central float and small stabilizing floats. Performance was modest because of its low-powered engine. The OS2U could also operate on fixed, wheeled, taildragger landing gear.
The Blackburn Shark was a carrier-borne torpedo bomber designed and built by the British aviation manufacturer Blackburn Aircraft. It was originally known as the Blackburn T.S.R., standing for torpedo-spotter-reconnaissance, in reference to its intended roles. The Shark was the last of Blackburn's biplane torpedo bombers.
The Lublin R-VIII was a Polish bomber, reconnaissance aircraft and seaplane designed in the late 1920s by the Plage i Laśkiewicz factory in Lublin. It was the first in-house design of Plage i Laśkiewicz, and the first with the name Lublin.
The Fokker G.I was a Dutch twin-engined heavy fighter aircraft comparable in size and role to the German Messerschmitt Bf 110. Although in production prior to World War II, its combat introduction came at a time the Netherlands were overrun by the Germans. The few G.Is that were mustered into service were able to score several victories. Some were captured intact after the Germans had occupied the Netherlands. The remainder of the production run was taken over by the Luftwaffe for use as trainers.
Fokker D.XVII, was a 1930s Dutch sesquiplane developed by Fokker. It was the last fabric-covered biplane fighter they developed in a lineage that extended back to the First World War Fokker D.VII.
The Blackburn Firebrand was a British single-engine strike fighter for the Fleet Air Arm of the Royal Navy designed during World War II by Blackburn Aircraft. Originally intended to serve as a pure fighter, its unimpressive performance and the allocation of its Napier Sabre piston engine by the Ministry of Aircraft Production for the Hawker Typhoon caused it to be redesigned as a strike fighter to take advantage of its load-carrying capability. Development was slow and the first production aircraft was not delivered until after the end of the war. Only a few hundred were built before it was withdrawn from front-line service in 1953.

The Fokker C.VII-W was a reconnaissance seaplane built in the Netherlands in the late 1920s. Sharing elements of the highly successful C.V design, the C.VII-W was a conventional, single-bay biplane with wings of unequal span braced with N-struts. The undercarriage consisted of a standard twin-pontoon arrangement, and the fin and rudder continued through to the ventral side of the fuselage, creating a cruciform tail. The pilot and observer sat in tandem, open cockpits. The wing structure was wooden with fabric and plywood covering, and the fuselage was of steel tube construction with fabric covering.
