The division was established on September 1, 1995 on the basis of the legendary 4th Submarine Squadron of the Kola Flotilla.
Currently it is reorganized as the 161st Submarine Brigade.
The point of deployment is “Polarny”.
The sleeve patch represents a black triangular heraldic shield with an arc plate at the top.
In the shield there is an image of a dolphin twining an anchor.
Upper left corner of the shield is crossed with a white-and-blue St. Andrew’s ribbon – the symbol of Russian Navy.
The dolphin symbolizes the sea power, safety and speed. The dolphin with the anchor means the balance between speed and slowness, i.e. the ancient allegory “Haste thee, slowly”.
The inscription on the arc plate of the sleeve patch reads: “THE NORTHERN FLEET FLOTILLA”.
During the entire period of its existence, the 4th Submarine Squadron was in increased attention among NATO forces. It was called “the great”, “the furious” and so on. These terms indicate that the squadron was respected not only by friends. The submariners themselves say: “As the combat anxiety was announced in 1941, it was not deactivated.”
The squadron’s submarines represented the USSR Navy in Cuba, Angola, Egypt, Syria, Tunisia, Libya, Algeria, Yugoslavia and the United Kingdom, where they were at friendly visits.
Over 25 years of inhuman strain in the compartments of submarines – that was the daily activities of the oldest Northern Fleet unit. The Submarine Brigade commander of the 4th Squadron – captain Igor Mokhov – behind which there were more than 10 autonomous campaigns, died of a heartbreak before the formation of teams in celebration of the Victory on May 9, 1985.
In September 1995, the 4th Submarine Squadron was reorganized as the 40th Division, and on December 1, 2001, as the 161st Submarine Brigade being a part of the Kola Flotilla of the Northern Fleet.
