The Khabarovsk class, or Project 09851 is a class of nuclear submarines under construction for the Russian Navy.

Development

The lead submarine Khabarovsk, was slated to be floated in June 2020. However, the launch was delayed. ^[1] This class of submarines is based on the Borei-class submarine's hull (other sources refers to the Project 949A class - to be verified), but is significantly smaller as it does not have the ballistic missile section. Surface displacement is reported to be about 10,000 tons. ^[2] The class is intended to carry six Status-6 Oceanic Multipurpose System long-range nuclear torpedoes, and will be the second submarine to carry this weapon after Belgorod. ^[3] The class is also likely to carry anti-ship and land-attack missiles, in addition to torpedoes. ^{[2] [4]}

According to the open sources, a total of three or four submarines have been ordered. However, while some sources suggest all the submarines are of the same class (Project 09851), others suggest that the follow-on boats could be from a separate class (09853). ^{[2] [5] [6] [7] [8]}
