Project 6457S Sprut

The Project 6457S Sprut fishery patrol vessel, upgraded by the Almaz CMDB, was commissioned to the Russian Coast Guard in June 2009. Built to a design by Germanys Abeking & Rasmussen, the Russian Coast Guards new vessel, project 6457S was built at Yantar Shipyards. The new 835-tonne Sprut has an overall length of 35.9 metres, a beam of 10.6 metres and a maximum draught of 3.48 meters. The vessel can achieve a top speed of 21.5 knots and can accommodate a crew of 24.

The ship was developed from the German Project 6457 patrol ship by the Almaz Central Marine Design Bureau to meet the Sea Navigation Register standards and special requirements of the Border Guard Service. The type ship in this series, Sprut (Project 6457s), was laid down on May 27, 2002 (on the Border Guard Day celebrated in Russia). It is used to counter illegal fishing in the Russian sea economic zone.

Considering high tactical and technical characteristics of this ship, as well as the urgent need in this type of ships, the Border Guard Command made a decision to launch series production of Sprut-type ships in 2003 (not less than 10 such ships were to be built) at the Yantar Shipbuilding Plant to reduce overall costs and save budgetary funds allocated for the acquisition of armament and military equipment.

What makes the Sprut ship so attractive for the Federal Border Guard Service is a new-generation vessel that has incorporated the latest technologies and advanced automation and computer systems used to optimize the ship's effectiveness and operating costs (cost- efficiency-marketability ratio).

The ship has 900 t displacement, 65.5 m length, 10.6 m width and 3.48 m draft. Its endurance is at least 30 days. Spruts sea-keeping ability is unlimited, and it can operate in all climatic areas. The cruising range at an economic speed is up to 12,000 miles. The ship has a complement of 15 men and can carry up to 10 passengers.

In terms of basic dimensions and lines, the Sprut ship has been designed as an intermediate version between a warship and a civil vessel to have the advantages of the latter (fuel efficiency) and the former (speed) to optimally accomplish assigned missions.

The Sprut ship is powered by a unique main propulsion system made by MTU (Germany) equipped with an automatic control system operated from the main command post. The CODAE diesel-electric propulsion system has a threefold redundancy and provides a full speed of 21.5 knots. The service life of the main propulsion plant is automatically calculated, depending on engine ratings used during operation and can amount to 36,000 hours. The diesel generator provides a 12-knot economic speed and an 8-knot patrol speed. The ship's pursuit capability is augmented by a speedboat available on board featuring a 30-knot maximum speed in sea state 5.

Active and passive ship stabilizers, an active rudder, bow and stern maneuvering rudders provide for the ship's high sea-keeping ability particularly important for patrol missions in Russia's economic zones in stormy Far-Eastern seas.

The Sprut prototype (a type ship of the German Coast Guard) successfully passed trials in the conditions of severe gale and 5 m high waves in the North Sea, displaying excellent sea-keeping ability and fully confirming the claimed performance.

Governmental expert agencies completed a feasibility study of the Sprut ship (Project 6457s) to be built by Yantar for the Federal Border Guard Service and confirmed the correctness of this decision. As a result, the Federal Border Guard Service received a modern new-generation specialized patrol ship designed for the protection of Russia's economic zone at a minimal cost (compared to Russian and foreign equivalents).

The patrol ship Bad Bramstedt of the German Coast Guard (Sprut's prototype) built by Abeking & Rasmussen, jointly with Yantar, was invited by the Russian Shipbuilding Agency to take part in Russia's first International Maritime Defence Show held in St. Petersburg on June 25-29, 2003.

The Concern pays special attention to the development and construction of small-displacement missile ships and boats armed with antiship missiles; their firepower is comparable with corvette and even frigate-class combatants. Their cost is two to four time less than that of the larger displacement ships. These small missile ships and boats draw a particular interest of Asian, African and Latin American countries.
