Some Giro thoughts

No USSR units that I know of used optical rangefinders - they went straight from stadia to LRF in the 70s on later model T-72 and 64 etc.

Thanks Andy that was my understanding.

I have one more question, how long did it take to range and aim with the Volna FCS, what was automatically entered and what was manual ?

My understanding is turret traverse speed is entered automatically from sensor in the turret ring, but round type, temperature, and range manually entered, with range determined from TK-1 laser rangefinder.

Once the solution was found, did the chevron (dot) on the scope automatically move, or was there simply some increments (for lead and super-elevation) that had to be matched manually to the solution produced by the computer ?

I have to disagree. Early T-72s were fitted with the TPD-2-49 coincidence rangefinder.




Notice the rangefinder ports on the turret roof near the sides. Early T-64s had a similar arrangement.
Naturally T-55/62 went straight to lase but as I said early production T-72/64 relied on optical units.

Marcello is of course correct, optical rangefinders were installed in the first T-64 A modernization in 69/1970, apparently lasers were not fitted till 81.
