TKB-539 Revolver Cannon

In the late '50s an experimental fighter aircraft called the Mikoyan Ye-152-1 was produced. It was an absurdly sophisticated machine for the time, capable of Mach 2.8+. It was fitted with either 2 TKB-495 or 2 TKB-539 revolver cannons. The TKB-495 fires the 23x115mm and is nothing special. However the TKB-539 was a 30mm, 4 chamber revolver cannon with a fire rate of 2000rpm and a muzzle velocity of ~3300fps (1000m/s). Left in below pic:

Does anyone know what round it fired? 30x155mm? 30x165mm?
 
In the late 1950's it could not have been the 30x165 which did not exist at that time. With a Vo of 1000 m/s we can also exclude the 30x155B and sowith this gun must have used a different cartridge - likely an experimental one.
 
The obvious (although not necessarily correct) answer is the 30x210B Soviet for the NN-30 naval revolver cannon which was being tested at that time. This had an MV of 1,050 m/s (although from a much longer barrel than this one appears to have). The NN-30 could fire at 1,000 rpm, but no doubt this performance could have been souped up for aircraft use.

Thanks. I was wondering about that cartridge too. If it does transpire to be the case, it must have been quite an armament.
 
I wonder if the projectiles of the NN-30 would have been any suitable for aircraft use. Getting hands on the gun one should measure the max. width of the feed slot.
 
I've read elsewhere that development of the AK-630 began in 1963, so maybe the 30x165mm was about in prototype form.
 
The decision to develop a new naval gun/missile system wasn't taken until 1963, so its too late. In any case, the highest quoted MV for the 30x165 is 960 m/s from a long barrel; from the shorter aircraft gun barrels it's 860 m/s.

On website about history of Tula State University write that ТКБ-540, ТКБ-539 and ТКБ-532 were made in 1955-56 years :)
 
I guess it must have been the 30x210B then unless anyone can definitely specify a different round.

Cheers.
