Design and development
The Yak-4 was an improved version of the Yak-2 with more powerful [Vous devez être inscrit et connecté pour voir ce lien] engines and a number of other
changes that were made to try and rectify the problems of the Yak-2.
Two additional fuel tanks were added in the outer wings to bring the total capacity up to 180 litres
(40 imp gal; 48 US gal) and the gunner's canopy was bulged to give him more room to use his 7.62 mm (0.300 in) [Vous devez être inscrit et connecté pour voir ce lien].
The upper fuselage was redesigned to improve the gunner's field of fire and the oil coolers were relocated from the sides of the engine nacelles to the 'chin' position to improve their performance.
