Dunay (Russian: Дунай) was a Soviet and later Russian icebreaking patrol ship in service with the Soviet Border Troops and later Coast Guard of the Border Service of the Federal Security Service of the Russian Federation. It was one of eight Project 97P patrol ships built by Admiralty Shipyard in Leningrad in 1973–1981.
Description
In the mid-1950s, the Soviet Union began developing a new diesel-electric icebreaker design based on the 1942-built steam-powered icebreaker Eisbär to meet the needs of both civilian and naval operators. Built in various configurations until the early 1980s, the Project 97 icebreakers and their derivatives became the largest and longest-running class of icebreakers and icebreaking vessels built in the world.[1]
The patrol ship variant, Project 97P (Russian: 97П), was developed as a response to the renewed interest of the Soviet Navy and Soviet Border Troops on icebreaking patrol vessels after United States Coast Guard and Canadian Coast Guard icebreakers began appearing more frequently near the country's northern maritime borders. New icebreaking patrol vessels were needed because existing Soviet naval vessels could not operate in ice-covered waters and large icebreakers, in addition to being unarmed and operated by civilians, could not be distracted from their primary mission of escorting merchant ships.[1]
Project 97P patrol ships are 70 metres (230 ft) long overall and have a beam of 18.1 metres (59 ft). Fully laden, the vessels draw 6.5 metres (21.3 ft) of water and have a displacement of 3,710 tonnes (3,650 long tons). Their three 1,800-horsepower (1,300 kW) 10-cylinder 13D100 two-stroke opposed-piston diesel engines are coupled to generators that power electric propulsion motors driving two propellers in the stern. In addition to being slightly bigger than the icebreakers they are based on, Project 97P lacks the bow propeller and features a bigger deckhouse built of aluminum-magnesium alloy to reduce weight as well as a helideck capable of receiving Kamov Ka-25 or Ka-27 helicopters.[1]
All Project 97P patrol ships were initially armed with a twin 76 mm AK-726 deck gun and two 30 mm AK-630 close-in weapon systems, but the ships operated by the navy were later disarmed.[1]
History
The fifth of eight Project 97P patrol ships was laid down at Admiralty Shipyard in Leningrad on 24 December 1976, launched on 5 August 1977, and delivered on 31 December 1977.[2] The ship was named Dunay after the Danube River and joined the maritime unit of the maritime unit of the KGB Border Troops in Petropavlovsk-Kamchatsky in the Russian Far East after transiting the Northern Sea Route.[1]
Following the dissolution of the Soviet Union, Dunay was passed over to the Coast Guard of the Border Service of the Federal Security Service of the Russian Federation.[1]
In 1997, Dunay participated in joint exercises with the United States Coast Guard cutter USCGC Storis and made a visit to Kodiak, Alaska.[1]
Dunay was decommissioned on 20 September 2017 and broken up in 2019.[2]
