Borei Class is a Russian fourth-generation nuclear-powered missile submarine. It is intended to replace the aging Delta III and Typhoon Class submarines becoming an important deterrent of the Russian Navy. It is the first class of submarines developed by Russia since the soviet era.

Designated Project 935, it began in 1996 to manufacture the first unit of the Borei Class submarine. The project name was changed to Project 955 and the submarine was redesigned to accommodate the new submarine-launched ballistic missile (SLBM) Bulava (SS-NX-30) in place of the abandoned R-39UTTH Bark missile.

Currently Yury Dolgoruky, Alexander Nevsky and Vladimir Monomakh are the three submarines ordered under this project. These vessels are designed by Rubin Marine Equipment Design Bureau and built by Northern Machinebuilding Enterprise.

The new submarine ordered would be named St Nicholas and the construction is expected to begin in December 2009. Further to this, Russia has plans to build another eight Borei Class submarines for its naval fleet by 2015.

Borei Class development

"Borei Class is a Russian fourth-generation nuclear-powered missile submarine."The first in the class of the submarines is the Yury Dolgoruky vessel. The total cost of the submarine is $713m including research and development expenditure of $280m.

Project 955A, the higher version of Project 955 might build the Vladimir Monomakh and other follow-up submarines. This programme would have various improvements and would have a different hull shape.

Construction

The construction of the Yury Dolgoruky was scheduled to start in 1996. Due to funding issues there were delays in the production of this vessel. The vessel's construction began in April 2007. In February 2008, the submarine was launched and it will undergo six more sea trials before it is commissioned with the Russian Navy by late 2009.

The vessel's commissioning might get delayed due to the setbacks of the Bulava missile which failed for six times of the 11 tests.

The other two submarines that are under construction are the Alexander Nevsky and the Vladimir Monomakh. They are expected to be completed by 2009 and 2011.

Missiles

Bulava SLBM (designated RSM-56 in the START treaty) which is based on the Topol M design would be fitted into the Borei Class submarines. These missiles are developed by the Moscow Institute of Thermal Technology and would be launched on the Project 955 platform.

"The first in the Borei Class of the submarines is the Yury Dolgoruky vessel."The missile is 12.1m long and has a diameter of 2.1m (including the launch container). It weighs a total of 36.8 metric ton and is capable of carrying six to ten re-entry vehicles with a yield of 100kt-150kt each.

The Borei Class submarines have lower displacement levels than the Typhoon Class, which can carry similar number of missiles. Yury Dolgoruky would carry 16 of these missiles while the improved versions of the Borei Class submarines might carry 20 of them.

The submarine will also carry six of the SS-N-15 missiles. Each SS-N-15 is a 533mm calibre anti-ship missile has a range of 45km capable of being fitted with 20kt warhead or a type 40 torpedo.

Propulsion

The submarine is powered by an OK-650 nuclear reactor, AEU steam turbine, a shaft and a propeller. The Borei Class submarines are the first in Russia to run on the pump jet propulsion system.

Brother no offence but wat does this post have to do with anti-sub copters coming in PN ?

 

[sadiqams]

these are for the F22s frigates.

Pakistan Navy acquires ASW helicopters from China

KARACHI: Pakistan Navy has acquired Anti Submarine Warfare (ASW) helicopters Z9EC from China. The induction ceremony was held here on Wednesday at Naval Aviation Base. Chief of the Naval Staff Admiral Noman Bashir was the chief guest on the occasion.

This is the first batch of the series of six helicopters to be procured as per the contract signed with M/s China National Aero Technology Import and Export Corporation (CATIC). The Z9EC helicopters have been built according to the specific requirements of Pakistan Navy and are capable to detect and destroy submarines. The aircraft is configured to carry torpedoes and is fitted with state-of-the-art pulse compression radar, low frequency dipping sonar, radar warning receiver and doppler navigation system. Talking to the media men after the inauguration, the chief guest said that these days the Indian ocean is experiencing intense activity and around 100 ships from different countries are operating at all times for safeguarding their interests.

These extraordinary developments are an indicator of the importance of the trade routes in these waters. Pakistan Navy is also conducting continuous deployment of ships and aircrafts to guarantee guarding our maritime interests. Commenting on the regional stability, the naval chief denied being part of any arms race but expressed resolve to maintain quality in naval platforms and enhancement of capabilities in consonance with the developments in the region.

He also expressed his full confidence in Chinese technology and termed it compatible with the Western one. “Pak-China relationship is time-tested and would further be strengthened with such defence collaborations like F-22 P frigates and Z9EC helicopters projects,” he added. Earlier, in his welcome address, Commander Pakistan Fleet Rear Admiral Asif Sandila highlighted salient features of Z9EC project. He apprised that apart from China, Pakistan is the first country that would operating these helicopters in ASW role.

Later, the helicopter made fly past and staged demonstration of its characteristics and maneuverability. Chinese Ambassador to Pakistan Luo Zhao Hui, representatives of M/s CATIC and a large number of senior naval officers and aviators of Pakistan Navy attended the ceremony. razzak abro

This shipborne ASW variant is based on French AS-565F Panther, and is equipped with an Agrion 15 (or indigenous KLC-1) surface search radar, a Thomson Sintra HS-12 dipping sonar and can carry one Whitehead A244 torpedo on the starboard side. A small beacon antenna is mounted on the roof of the cabin. This variant could provide data link between ship and YJ-83 AShM for over-the-horizon attack.

Agrion 15 (TMV-118A). The Agrion 15 radar was designed as a multi-purpose radar primarily for helicopter use, but with potential for fixed-wing operation. It is intended for Anti-Surface Warfare (ASuW) and Anti- Submarine Warfare (ASW) roles. Agrion 15 allows the platform aircraft to operate autonomously or in conjunction with surface-unit weapon systems. In the missile guidance mode Agrion 15 is designed to detect the AS-15TT missile after launch by means of an auxiliary antenna, automatically track both missile and target, measure the differential between target-missile range and bearing, and transmit differential data to the missile using a transmitted pulse as guidance link. A number of secondary missions were incorporated into the design, including coastal patrol, Search and Rescue (SAR), flight safety, navigation, and weather avoidance.
Acting in the ASW role, Agrion 15 is said to be capable of detecting snorkels and periscopes in rough seas, and functions as an OTH radar for surface units. In both the ASuW and ASW role, the radar is optimized for targeting and tracking the Thomson-CSF AS-15TT missile system. The performance of the radar is enhanced by the use of pulse compression, frequency agility, monopulse and Track While Scan (TWS) technology. The equipment has Built-In Test Equipment (BITE). The use of pulse com¬pression improves the chances of remaining undetected by passive monitoring.

Typical detection ranges are 25-30 nautical miles for snorkels, 55-60 nautical miles for FACs and 120-125 nautical miles for medium-sized ships

Its similar to Eurocopter Dauphin.

Z-9EC ASW variant inducted 23 September 2009, configured with pulse-compression radar, low frequency dipping sonar, radar warning receiver and doppler navigation system. Armed with torpedoes. To be carried on the F-22P Zulfiquar-class frigates.

I think Pak shlould get 20 - 25 these helos...............1 complete Sqd

 

[MZUBAIR]

Lets wait for WZ-10.
We also needed 20 - 30 of these WZ-10

Z-9 is a basic version of 1980s naval Dauphin and for today's ASW standard it is pretty outdated but a decent platform for F-22P. I dont see why Pakistan navy should acquire a squadron of 1980s standard ASW helicopter and mind you todays Dauphin is very different.
IMO if PN does decides to raise a independent squadron, Super lynx is a perfect ASW ASuW helicopter.
20-25 Z-9 is not worth the investment.

 

[ice_man]

the question is what other platforms CAN be compared with the Z9 and what does India have in terms of ASW heli's?

the Z9 would be a good investment if it comes with ToT....so that we can actually learn to make heli's and with time improve and make more potent helis by oursevles!!

 

[TaimiKhan]

Getting more Z-9s is a good option, their performance is not that bad, PN would be secure in the matter of keeping them operational not like the Lynx that where grounded due to non availability of spares & stuff.

The main issue would be the electronic suite for Anti-Ship/Submarine Warfare, radars, sonars. these should be of the latest technology western if possible to give PN an edge.

One helicopter of Z-9 caliber for ASW & one another heavy one in the Sea King class for transport/supply role would be a good combination.

Both Lynx & Z-9 are of the 70s design era. Improvements have been done in both but for both the electronic warfare suites would be the decisive factors in a war like situation.

Thats not the issue. Most of today's pakistan military acquisition involves surplus amount of spares "F-16" is the prime example which assures the availability during war time.

The main issue would be the electronic suite for Anti-Ship/Submarine Warfare, radars, sonars. these should be of the latest technology western if possible to give PN an edge.

the current version of Z-9 we are getting are nothing but reverse engineered 1980s Dauphin with indigenous subsystems.

One helicopter of Z-9 caliber for ASW & one another heavy one in the Sea King class for transport/supply role would be a good combination.

Sea king is merely a utility helicopter so ASW and Utility chopper is not a good combination.

Both Lynx & Z-9 are of the 70s design era. Improvements have been done in both but for both the electronic warfare suites would be the decisive factors in a war like situation.

Super Lynx and Z-9 ASW have no comparison as simple as that, yes both are pretty old designs but thats not the issue.

I have not even mentioned the armaments super lynx can carry.
