"Krylov Center Presented Long-Range Corvette Concept with 24 Caliber CMs"

The Krylov State Scientific Center for the first time presented the advanced corvette concept at the Army-2017 forum. Thanks to improved seaworthiness, the ship can operate in ocean zone and carry up to 24 Caliber cruise missiles, Valentin Belonenko, the concept developer heading the naval ships advanced designing department at the Krylov Center, told Mil.Today.

According to Belonenko, the corvette-subclass multirole ship combines seaworthiness, fire power and the capability to operate in littoral, long-range sea and ocean zones. Estimated displacement of the ship is 2,000-2,500 tons.

"This corvette is armed nearly like a frigate. Commissioning of Calibers helped to perform attack missions using small-size ships. All warships must pose maximum threat for the opponent. This will enable to use the navy more flexibly, especially in the present-day conditions", added the ship designer.

High sea-keeping performance is achieved through wider hull, special shape of the underbody and the forecastle, said the expert. The ship’s center of gravity is switched to aft, which helps to damp the seel. The corvette is supposed to have water-jet engines, and if faster speed is needed, the gas-turbine ones, too.

In the interview to Mil.Today, Valentin Belonenko emphasized that the ship creation process was at the very beginning: "It is not even a project yet, just a concept, a kind of a military and technical research". As for him, the corvette’s characteristics, including weapons configuration, can be changed depending on the navy’s demands.

The ship presented at the Army-2017 show is equipped with 16 vertical launch systems for Caliber cruise missiles. Designers say number of missiles can be increased up to 24.

Air defense of the corvette is ensured by 16 long- and 32 short-range antiaircraft missiles. In addition, the ship is equipped with the 100-mm standard gun mount and two 30-mm six- (or twelve-) barreled rapid-fire automatic guns. Antisubmarine and antitorpedo weapons are represented by two Paket-NK 324-mm four-tube torpedo launchers.

On August 23, the Krylov center’s showroom was visited by deputy defense minister Yury Borisov. The shipbuilders explained him advantages of the ship over analogous projects.

Earlier on, media called the prototype corvette Breeze, its model was supposed to appear at the IMDS-2017 naval show, but at the last minute the demonstration was cancelled.

The focus in the development of the advanced corvette Briz (Breeze) was placed on the optimization of the corvette’s seaworthiness, including through various ship stabilization means. As a result of the Krylov Center’s efforts, the corvette, with a very moderate displacement, carries extremely powerful weapons for this type of ships consisting of 24 universal vertical launchers for surface-to-surface missiles, as well as 16 vertical launchers for longer-range surface-to-air missiles (SAM) and 32 - for short-range SAMs, the Zvezda TV channel reported.

Its artillery includes the 100mm A-190 turret mount, a pair of 30mm AK-630 six-barrel Gatling-type rapid-fire systems, and one Duet system with two similar turrets. To counter enemy submarines, the 324mm PAKET-NK torpedo tubes are mounted alongside. Detection of submarines is carried out by a sonar system with antennas housed in the bow bulb, under the keel and a towed array, and also with the help of the Ka-27 ASW helicopter, for storage of which there is a place in the superstructure for the hangar.

Krylov Center spokesman Yuri Chervakov explained to the Zvezda TV channel that the "2000 ton corvette" is the latest development from a team of researchers. It continues the line of next generation strike surface ships, the most typical of which is the destroyer concept. Despite a marked difference in displacement (seven times), the corvette and destroyer share a common design, thus implementing an innovative approach to the design of future warships. Visually, they are distinguished by a distinctive "tower" form of the superstructure, other radar signature reduction measures, as well as by the special outlines of the underbody, which significantly (almost twice) reduce the wave-making resistance.

Reduction in the resistance to movement makes it possible to increase the speed while maintaining the main parameters of the propulsion plant (which is relevant to the destroyer), or reduce the required power at a given speed (relevant to the corvette). In the latter case, it becomes possible to reduce the weight of engines, and, accordingly, increase ammunition load, provisions, etc. According to the Center, the "2,000 ton corvette" is another step towards further improving the configuration of the warships of this class.

The "2000 ton corvette" concept, presented at Army-2017, is designed to use a 32,000 hp CODAG propulsion plant, that is, with cruising diesel engines and gas-turbine boosters for "chase" at up to 30 knots.


The Krylov Center’s specialists still have to make great efforts to ensure that the customer approves the proposed concept and gives the go-ahead for its further development. The need to immediately move the Briz to the preliminary design and then full-scale development stages is not so obvious. The matter is that earlier it was decided to build a large series of Project 20380 ships (up to thirty hulls). The military officials opted for supplementing the Baltic, Northern and Pacific Fleets with at least six corvettes of this type, which totals 24 ships.

Project 20380 is a corvette with a standard displacement of 1800 tons and a full load displacement of 2,200 tons, which is close to the corresponding figures for Briz. The latter is several meters longer, but a little narrower. The construction of the lead hull began at the turn of the century and the Steregushchy has been in service for almost ten years. Improvements were made to the basic design since its commissioning. The follow-on ships of the project featured reinforced air defense capabilities achieved through the replacement of the Kortik air defense missile/gun system with the Redut SAM system.

Replacement of the Uran missile system with a more powerful Kalibr-NK will be the next step towards improving the basic version. The improved ships received designation Project 20385. The series of Project 20385 ships will consist of four hulls. Later, the new ships will be built to improved Project 20386.

Among the innovations introduced in the above project, is a superstructure of composite materials. It will be made using the vacuum infusion method. In short, Project 20380 proved to be suitable for continuous improvement and modernization, while Steregushchy started a large series of corvettes, the Zvezda TV channel recalls.

Anyone know what that hexagonal block immediately aft of the main VLS is? It's obviously a launcher of some description, with two inclined tubes firing to either beam, but the description doesn't identify anything it might represent. Kalibr and the SAMs will be in VLS tubes, while the 2x4 Paket-NK launchers are probably behind the dark panels on the hull aft.

Yup, and presumably capable of being pointed at the target bearing. Not sure as to the need for that in this modern age - maybe gaining a small amount of range?

*Edit* An anti-submarine weapon would find a rapid slew capability advantageous - but those tubes look much wider than a boosted anti-sub weapon would need.

I don't believe there's physically room to slew the mounting, look at the side view of the bow in post 2. And if you could the efflux would be directed at either the base of the superstructure, or the aft side of the VLS array, neither of which is ideal.

WRT ASW weapons, those can go in the VLS with the rest of the Klub variants.

Not a steerable launcher, obviously, but it does have missiles aimed out from both sides, because they don't want to have them fly a 180-degree turn before coming onto course. Anything that potentially puts the launch platform back under the missile's track seems like an unnecessary risk.

They look quite a bit like Uran tubes, but could be a placeholder for just about anything. Wouldn't be the first time the model didn't match the latest actual design.
