Operations

Before June 1995 AS-26 was first assigned to the Soviet and then to Russia's Northern Fleet. From then on the DSRV was assigned to Russia's Baltic Fleet.[1]

It is deployed from the Kashtan-class salvage ship SS-750. The two have participated in submarine rescue exercises in the Baltic Sea.[2][3]

On 22 September 2022, the AS-26 and its mother ship SS-750 were observed by the Royal Danish Navy patrol boat HDMS Nymfen above the route of the Nord Stream 2 gas pipeline four days before the pipeline was sabotaged.[4][5]
