Purchased in the UK jet engines gave further development of Soviet jet aircraft. 11 Martha 1947 g. USSR Council of Ministers issued a decree, which he commissioned several design bureau to develop for them new types of aircraft. AS. Yakovlev decided to create a frontline fighter with straight wings and engine "Derwent V», though its competitors have designed aircraft with swept wings. In the case of competitors' success, his bureau would be lost in the field of fighters initiative. Therefore, Yakovlev decided to develop just two fighters: First Yak-25 (first with the same name) officially created, and the lighter the Yak-23 - on its own initiative.
Chief designer returned to the aircraft hull steps scheme. cause, apparently, It was the Yak-19. The large pressure loss in a long curvilinear channel before turbojet compressor, As in the Yak-19, Yakovlev again returned to his first fighter. While the engine was not real, designers worked only with its overall scheme, and, when he entered the bureau, aircraft structure almost did not have to finalize. The engine was mounted under the cockpit. wing-in-one, spars "arch" - curved bypass engine. Wing and landing gear as in the Yak-19. Despite the powerful weapons and pressurized cabin, the plane was very easy. empty weight is not reached even two tons.
According to the Minister's order, associated with the preparation of an air parade 1947 city, AS. Yakovlev ordered to finish the construction of the aircraft to 15 June. test aircraft began in the summer, a 24 September 1947 g. We have already completed. Experienced test pilot machine MI. Ivanov. 3 August the aircraft was demonstrated at the air parade in Tushino. At trial, he showed the maximum speed at sea 932 kmh. his agility, climb and takeoff and landing characteristics were the best aircraft in its class. In the second experimental aircraft Yak-23 were carried out state tests, leading was appointed test pilot GA. Sedov. Conducted aerial combat jet bomber Tu-12 show, that it can successfully deal with the shock of the new-generation aircraft.
The Yak-23 was one of the best jet aircraft with straight wings. Along with the MiG-15 ILA-15 Yak-23 fighter was launched in a series of, true, a small, despite its straight wing. To end 1950 g. built in Tbilisi 310 aircraft Yak-23. In the Soviet Union Yak-23 had wide application, the vast majority were delivered to friendly countries.
AT 1949 g. was built double training Yak-23 - Yak-23UTI. First flew test pilot SN. Anokhin 29 Martha 1949 g. Customers abandoned Yak-23UTI due to the small number of its combat troops and prototype, mainly, due to direct wing. Besides, close turned cab, and to improve visibility of the rear canopy made convex. Unfit aircraft and due to insufficient range: stall "ate" a significant amount of fuel system, so it is not enough, and external fuel tanks. A different arrangement of double Yak-23 offered Romanian engineers. They arranged a co-pilot's seat behind the main cabin and saved not only the distance, but even the basic contours of the fuselage.
