Poznámka:
Note:
Některé letouny nesly místo kanónu NS-37 kanón VJa-23
Yak-9 armed with a 37 mm Nudelman-Suranov NS-37 cannon with 30 rounds instead of the 20 mm ShVAK, cockpit moved 0.4 m (1 ft 3 in) back to compensate for the heavier nose. Initially poor quality control led to multiple oil and coolant leaks from cannon recoil. Recoil and limited supply of ammunition required accurate aiming and two-three round bursts. Yak-9T was widely used against enemy shipping on the Black Sea and against tanks, but was also successful against aircraft with a single cannon hit usually sufficient to tear apart the target. Time to turn a complete circle: 18–19 sec.

History:
At the turn of 1942 and 1943, Yakovlev's OKB was tasked with installing an anti-tank gun with excellent penetration into the Yak-9 fighter.

For this purpose, the Yak-9D was used, the fuel tank had to be removed, the cabin moved 400 mm backwards so that the 3,400 mm long barrel of the gun could fit into the fuselage. Tests from March 1943 were satisfactory, and so by May 1943 the new Yak-9T-37 was in production.

At the front, it suitably complemented the Il-2 fighters, which it could also protect from enemy fighters.

However, one disadvantage was brought by the installation of the 37 mm calibre gun - it could not be fired in bursts, the light Yak was literally knocked off course and the second shell landed just a few metres from the first. Some pilots had this cannon replaced by the VJa-23 23 mm calibre cannon, which could penetrate 30 mm thick armour at a distance of 400 m, if the missiles were falling vertically. However, there are also known cases where a 20 mm ŠVAK gun or even a UBK machine gun was installed at the pilot's request.
