The Fokker T.V is a twin-engine medium bomber, a cantilever mid-wing of a mixed design, with a twin tail and retractable landing gear. Developed under the leadership of F. Hentzen and Jiri Szatzki at the Fokker plant, first flight on October 16, 1937. Operated only in the Netherlands Air Force.

Holland, where in the early 1930s its own vision of the concept of an "air cruiser" - Luchtkruiser, focused primarily on defense, was formed, since Holland had not planned any offensive wars with its neighbors since the beginning of the 19th century.

In accordance with this concept, the new aircraft, designed to become the basis of the Dutch military aviation, was supposed to ensure air superiority over its own territory. A long flight duration was required to carry out long patrols and intercept enemy bombers at distant approaches. In addition, the significant combat radius made it possible to use the aircraft for the defense of vast possessions in the Dutch East Indies. Small arms were provided for very powerful at that time - two 20-mm cannons and several machine guns.

At the beginning of 1933, a proposal to design an "air cruiser" was sent to the leading Dutch aircraft manufacturer - Fokker. The design group was headed by engineer F. Hentzen, and M. Beeling supervised the development. However, the first version of the preliminary design did not meet with the customer's approval. Therefore, in March 1934, Hentzen was replaced by the famous designer Erich Schatzky.

Although the aircraft was still listed as an "air cruiser," it was actually considered a medium bomber.

On February 14, 1938, the official ceremony of handing over the first Fokker T.V to the military took place at Susterberg airbase. During the year LVA (Luhtvaartafdeeling - Netherlands Air Force) received ten more such machines (numbers 851-860). The arrival of new aircraft made it possible to form the BomVa (Bombardement Vliegafdeeling) bomber air group.

In 1939, the company produced the last five Fokker T.Vs, but this batch, although operated in BomVa, was not officially accepted by the customer - the contract with Fokker was terminated under the pretext of low technical reliability of its bombers. In addition, the operation showed a much higher than anticipated oil consumption for the Pegasus engines. The company was forced to carry out improvements on the already delivered machines, installing oil tanks of increased capacity.

A total of 16 production aircraft were produced, the prototype was not manufactured.

Three-bladed Hamilton Standard propellers with a diameter of 3.05 m. Fuel system - two tanks in the center section, with a capacity of 750 liters each.

Armament: 20-mm Solothurn cannon in the bow mount (ammunition from 10-round magazines; ammunition - 120 rounds) and four 7.92-mm FN Browning machine guns with 600 rounds of ammunition per barrel (one at the top, bottom, stern and airborne installations); up to 1000 kg of bombs with caliber 50, 100, 200 and 300 kg in various combinations in the bomb bay (the bomb bay doors are hydraulic).

Crew - 5 people: navigator-bombardier (who also served the cannon), pilot, gunner serving the upper unit (also known as reserve pilot), gunner-radio operator, gunner of the tail unit.
