The Yakovlev Yak-19 was a Soviet fighter aircraft that first flew in the 1940s. It was Yakovlev's first plane made completely from metal. Only two planes were built. The aircraft was known to US intelligence as Type-7.

Design and development

While pedecessors Yak-15 and Yak-17 had been based on piston engine fighters like the Yak-3, the Yak-19 was a complete new development. Its engine was the RD-10F turbojet, the world's first jet engine with afterburner, developed at TsAGI. First prototype Yak-19-I started early 1947 with test pilot Sergej Anochin. Second prototype had a changed dihedral of the horizontal stabiliser and added tip tanks. The wings of the Yak-19 were used for developing wings for the Yak-23.

Operational history

The plane was first seen by the public on 3 August 1947 Soviet Aviation Day, at Tushino airfield. Testing ended in 1947. No production was started as other types with better performance were available by then.
