One of the U.S. Navy’s top submarine officers was so impressed with Russia’s new Project 885 nuclear attack boats that he had a model of K-329 Severodvinsk built for his office.
Rear Adm. Dave Johnson, Naval Sea Systems Command’s (NAVSEA) program executive officer (PEO) submarines said he had the model of Severodvinsk placed outside his office in a common area so that he could look at it every day on his way to his office.
“We’ll be facing tough potential opponents. One only has to look at the Severodvinsk, Russia’s version of a [nuclear guided missile submarine] (SSGN). I am so impressed with this ship that I had Carderock build a model from unclassified data.” Johnson said last week during the Naval Submarine League’s symposium in Falls Church, Va.
“The rest of the world’s undersea capability never stands still.”

The Russian attack boat had been in construction since 1993 and only entered sea trials late in 2011. The boat finally became operational earlier this year. A cash-strapped Russian Federation had to repeatedly delay completion of the submarine in the chaos that followed the collapse of the Soviet Union.
Severodvinsk is the most capable Russian attack submarine ever built and leverages many of the technologies the Soviet Union invested in during the 1970s and 1980s.

The 13,800-ton, 390-foot long, submarine is highly automated vessel with a crew of only 32 officers and 58 enlisted submariners.
It is far quieter than previous Russian submarines and has a maximum “silent” speed of about 20 knots.
The U.S. Naval Institute’s Combat Fleets of the World said some reports suggest the vessel might have a maximum speed of between 35 and 40 knots. However, most Russian reports state a maximum speed of 35 knots. Like most new nuclear submarine designs, Severodvinsk’s reactor is designed to last for the life of the boat.
According the Office of Naval Intelligence (ONI), while the new Russian submarine is quieter than the Improved Los Angeles-class boats, the new vessel is not quite as silent as the Seawolf or Virginia-class. However, the Soviets were always only lagging slightly behind U.S. in quieting technology according to Navy sources. The Russians are already building improved versions of the Yasen design.
Unlike most Soviet submarine designs, the Yasen-class boats do not make use of a double-hull—instead it has hybrid design with a lighter structure over the vessel’s pressure hull according to Russia media reports.
Another unique feature for a Russian vessel is that it incorporates a spherical bow sonar called the Irtysh-Amfora for the first time. As a result, Severodvinsk has its torpedo tubes located at about mid-ship like U.S. submarines. The vessel has eight torpedo tubes, four of which are 650mm tubes while the rest are 533mm tubes. Combat Fleets of the World estimates that the Yasen-class might carry as many as 30 torpedoes.

Like most Russian attack submarines, the vessel’s primary weapons are in the form of heavy anti-ship missiles. The boat has 24 missile tubes which can carry the supersonic NPO Mashinostroyeniya P-800 Oniks anti-ship missile which can hit targets roughly 200 nautical miles away. Severodvinsk can also carry Novator RK-55 Granat nuclear-capable 1,600 nautical mile-range subsonic land attack cruise missiles. Additionally, the Yasen-class boats can also launch the 3M14 Kalibr and 3M54 Biryuza land attack and anti-ship missiles, which have a roughly 300-mile range, though its torpedo tubes.
It also carries 91R anti-submarine missiles and has the capability to lay mines along with its normal complement of torpedoes.
Some Russian sources such as Russia Beyond the Headlines suggest that Severodvinsk is equipped with active anti-torpedo defenses and some sort of anti-air capability. The later would not be unprecedented, the Project 941 Akula—known better as the Typhoon-class ballistic missile submarine—was equipped with a 9K38 Igla surface-to-air missile system for ship self-defense.
Russia is expected to build eight Yasen-class boats. Since Severodvinsk took almost two decades to finish, the subsequent boats have many technological refinements to improve on the original Project 885 design. The next two Yasen-class boats are already under construction at the Sevmash shipyards in Severodvinsk, Russia. Kazan was laid down in July of 2009 while Novosibirsk was laid down July of 2013.

Cherbourg based CMN (Constructions Mecaniques de Normandie) has unveiled the C Sword 90 stealthy corvette at the Euronaval naval expo in Paris this week. The stealth vessel is one of three new ship designs the company is launching, all positioned to address the growing needs of world navies to support increasingly demanding missions encountered at the high sea and littoral waters.
At Eurosatory 2014 CMS unveiled the latest concept design of its new C Sword 90 stealth corvette, a direct descendant of the Combattante family of compact missile boats that was first introduced in the 1960s. Image: CMS

At Eurosatory 2014 CMS unveiled the latest concept design of its new C Sword 90 stealth corvette, a direct descendant of the Combattante family of compact missile boats that was first introduced in the 1960s. Part of its efficiency results from the inversed stem, contributing for enhanced propulsive efficiency and sea keeping. The round bilge shaped hull also contributes to better endurance in strong wind and rough sea conditions. Image: CMS

The distinctive shape of the C Sword 90 depicts an innovative hull formation and superstructure design with sloped surfaces, developed in collaboration with naval architect Thierry Verhaaren, who also designed the Baynunah missile boats CMS has built for the UAE.The vessel is designed for operation at the high sea, littorals and coastal area. The hull is made of steel and superstructure is made of steel and aluminium.
The C Sword 90 carries a powerful combat systems package  comprising surface, anti-submarine and anti-air weaponry, guns, countermeasures and a wide range of ISR sensors.

The C Sword 90 carries a powerful combat systems package comprising surface, anti-submarine and anti-air weaponry, guns, countermeasures and a wide range of ISR sensors.

 
The vessel provides a compact, yet versatile multirole craft packinghigh firepower and an extensive sensor package for Intelligence, Surveillance & Reconnaissance (ISR) missions and ESM/Comint electronic surveillance and electronic warfare capabilities. The primary sensor is an unspecified ‘new generation’ phased array radar, comprised of four flat panels mounted on the upper superstructure. In addition the vessel EO package is also configured to support some of the weapon systems with fire control functions. An integrated bridge control and communication systems help automate many procedures and reduce crew workload.
The boat has also the facilities to operate two RHIBs, which can also be unmanned surface vessels (USV) and underwater unmanned vessels (UUV).

The boat has a large flight deck supporting a 10 ton helicopter day and night, or an unmanned helicopter (VTUAV). It also has the facilities to operate two RHIBs, which can also be unmanned surface vessels (USV) and underwater unmanned vessels (UUV).

In addition to maritime missions including surface and anti-submarine warfare the vessel is well equipped to conduct maritime security missions, and support land operations from the sea To carry out those missions the C Sword 90 can be configured to support commando and ground operations operating a helicopter and two 11 meter Rigid Hull Inflatable Boats (RHIBs). These configurations can also supported by loading two containers, storing mission specific payloads, cargo and supplies. The boat has a large aft deck configured to operate one medium size (10 ton) helicopter or unmanned aerial system (UAS) in day and night. The boat has also the facilities to operate two RHIBs, which can also be unmanned surface vessels (USV) and underwater unmanned vessels (UUV). The C Sword 90 is operated by a crew of 65 personnel. The ship also has berths for 20 additional personnel.
The design has been optimized to sustain high maximum speed (28 knots) and extended autonomy, covering 7,000 nautical miles with an average speed of 12 knots. (It would do 5,000 nm cruising at 14 knots). Part of its efficiency results from the inversed stem, contributing for enhanced propulsive efficiency and sea keeping. The round bilge shaped hull also contributes to better endurance in strong wind and rough sea conditions.
The corvette’s firepower consists of one 76mm or 57mm gun mounted at the fore section and two remotely controlled weapon stations on port and starboard side, mounting 20mm or 30mm guns. The vessel is equipped with eight launchers of MM40 Exocet anti-ship missiles plus a vertical launcher packing 16 anti-air/anti-missile missiles. Additional air defense is provided by two additional launchers mounting two short-range anti-aircraft missile. Decoy systems are also used for self-defense offering both an anti-missile protection with radar or infrared guidance and along with electro-acoustic anti-torpedoes protection.
The vessel is designed to accommodate the infrastructure and equipment necessary for anti-submarine warfare (ASW) operations, including a hull mounted sonar, a towed sonar and two torpedo-launching tubes each mounting three tubes.
The biggest naval vessel ever built by the Cherbourg Shipyard, C Sword 90 is one of three new designs CMN unveiled at Euronaval – the others were the Ocean Eagle trimaran, configured as patrol boat or mine hunter and a new variant of the classic Combattante missile boat – the 46meter long FS46.
The Normandy based shipyard that has been building trawlers and mine sweepers since 1948 introduced the Combattante class patrol boat in 1963, a design that was later adapted by the Israelis with their Saar II gunboats and Saar III missile boats, an innovative concept pioneered by the Israeli Navy with its Gabriel anti-ship missile. By 1967 CMS completed six Combatant II boats for the Israelis, but the delivery of those boats was blocked by the arms embargo the French government imposed on Israel following the 1967 Six Day War. The boats were later smuggled to Israel fromCherbourg and sailed to Israel on a clandestine trip. Since the construction of those first hulls CMN delivered more than 90 Combattante class boats to navies around the world.

CMS continues to develop new mine hunters and missile boats, introducing the CIRCE mine hunter in 1970 and Combattante II built for the German Navy in 1973, Combattante III built for Greece in 1977 and IIIM delivered to Tunisia in 1983. In 1994 the company introduced the DV15 High-speed Interceptor and in 1997 delivered the first of eight P37 patrol boats for the Kuwaiti Navy. In 2009 CMN delivered the first of six Baynunah stealthy fast attack crafts (FAC) built for the UAE.
