  The project of the submarine tenders was developed in the central design bureau "Baltsudoproekt" under the leadership of the chief designer V. I. Mogilevich. The main observer from the Navy was Captain 1st Rank G.V. Zemlyanichenko. The construction of the lead ship was completed in Nikolaev at the Black Sea shipyard in 1958. In total, seven tenders of project 310 were built for the Soviet Navy in 1958-1963.
  
  Don-class submarine tenders had a total displacement of 7150 tons and 5030 tons while they're empty. Main dimensions: maximum length - 140 m, width - 17.67 m, draft - 5.6 m. Two-shaft diesel-electric main power plant with a capacity of 4000 hp. with. provided the ship with a full speed of 16 knots. The cruising range reached 3000 nautical miles (at a speed of 12.5 knots), autonomy - 40 days. The crew consisted of 350 people, including 28 officers.
  
  They could serve four submarines of Project 611 or Project 613. The equipment of the floating base was capable of providing navigational and emergency repair of the hull, mechanisms and weapons and storage of 42 533-mm torpedoes in a special room. A 100-ton crane was housed at the bow of the ship.
