Comparable TYPE 214 SUB VS AMUR 1650 SUB

A Layman's analysis :

1.INTRODUCTION




AMUR 1650 SUBMARINE
• It is a new 4th gen diesel electric ,export version submarine which is have been laid down at the Admiralteiskiye Verfi
state-owned shipyard in St. Petersburg.Designed to destroy hostile submarines and surface ships, to protect friendly naval bases, seacoast and communications, as well as to carry out reconnaissance missions.

TYPE 214 SUBMARINE
• The Type 214 is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The Type 214 submarine is derived from the Type 212, but as an export variant it lacks some of the classified technologies of its smaller predecessor.

It is well equipped to undertake a wide scope of missions ranging from operations in littoral waters to ocean-going patrols. The modular weapon and sensor mix, in combination with the submarine's air-independent features, makes the Class 214 predestined for
•anti-surface ship and anti-submarine operations
•intelligence, surveillance and reconnaissance tasks
•Special Forces operations.

well TYPE 214 SUBMARINE has much better propulsion than AMUR 1650 SUBMARINE thanks to it's better & efficient AIP system although both have skewed seven-bladed propeller .

6.AIP SYSTEM (POWER SUPPLY)



AMUR 1650 SUBMARINE

• The provision is made for the boat to be fitted with an air-independent propulsion plant with electrochemical generators to considerably increase submerged endurance and cruising range. The plant with stock of reagents is located in a special compartment module, which can be incorporated into the submarine during construction or repair / refit.

ЦКБ МТ Рубин: Amur 1650

•. According to estimates, Kristall-27E AIP system will increase the Amur Class submarines' submerged endurance by 15 to 45 days (the longer endurance is ensured by a short-term operation of the diesel engine in the snorkeling mode).

•The Kristall-27E AIP plant, featuring the intermetallid storage of hydrogen, cryogenic storage of oxygen and low-temperature electrochemical generator with alkali matrix electrolyte, fully meets all requirements including those of fire/detonation safety, and can beat the AIP system of Project 212 submarines, surpassing it in terms of fuel efficiency and shore-based support facilities due to the availability of dedicated autonomous shore-based refueling complex.

•The shore-based refueling complex does not integrally belong to the AIP system. However, it can be supplied optionally: this feature contributes to the competitiveness of the Russian project. Customer will receive in a single package the autonomous refueling complex which will provide hydrogen and oxygen for the submarine's AIP system in peace and war time

RECENT UPDATES

•TsKB Rubin is testing an AIP generator for submarines, RIAN reported in Sep 13 according to Rubin's Gen Director Andrey Dyachkov. He criticized the German hydrogen elements for flammability of their storage. The currently developed Russian AIP is built on the same electro-chemical generation principle, as hydrogen elements, but uses different less flammable reagents. The chemical ingredients used in the new AIP are not disclosed however. Like foreign analogs the last Russian AIP is built in plug-in module. Dyachkov also said Rubin is working in parallel to improve the lithium-ion batteries for subs. Currently the installation of lithium-ion batteries allows to make underwater time longer on 40%, while it's only 35-40% of the theoretically limits of this technology.

TYPE 214 SUBMARINE
• Performance of the AIP system has been increased withtwo Siemens PEM fuel cells which produce 120kW per module

• In Type 214 submarines the two BZM 120 fuel cell modules are connected to the ship’s power system via a DC/DC converter
allowing adaptation of the fuel cell power plant to different battery voltage levels .This becomes
important in retrofit projects in which an integrated fuel cell system, consisting of the fuel cells, oxygen and hydrogen
storage tanks, control system, process equipment and product water tanks,is integrated into an already existing submarine during a major overhaul.

• These service proven components completely satisfy military specification requirements with respect to magnetic signature,
low electrical stray field characteristics, system safety standards, acoustic properties, and shock/vibration criteria.
http://www.sea.siemens.com/us/inter...at the Advance Naval Propulsion Symposium.pdf

• Endurance: 3 weeks without snorkeling, 12 weeks overall
Using the AIP system on submerged patrol and intercept missions enables the boat to remain submerged for up to 13 days at a speed of 4 kt. Submerged sprint speeds of between 16 and 20+ kt are possible for periods of a few hours several times during a 50 day mission. At a speed of 6 kt the mission range is almost 12,000 n miles. Endurance will be 84 days.The fuel cell works at an operating temperature of 70 to 80ºC, which makes the submarine difficult to detect using external heat sensors.

Hellenic U214 pics (Greek Turkish Affairs Forum)

Regarding AIP system TYPE 214 SUBMARINE has a better Siemens PEM fuel cells(BZM 120)AIP system which give sub much more endurance days & energy efficient AIP system as compare to AMUR 1650 SUBMARINE's Kristall-27E AIP system.But russian AIP systems are claimed to be more safer as compare to german AIP system as they use less flammable reagents as claimed by russians.Russians are now currently working & developing 3rd gen AIP system which can give them nearly 90 days endurance

• MINES : PMK-2 ANTI-SUBMARINE MINE SYSTEM
The caliber of the PMK-2 weapon is 533 mm and its length is not more than 6 m. The distinguishing feature of these systems is that though they are basically active mines, they attack targets themselves. The equipment of these mine systems detects and classifies an underwater target, determines its course and running depth, optimizes the target intercept trajectory and generates a command to launch either a rocket, which runs at a speed of about 80 m/s, or torpedo.
Sea Mines

TYPE 214 SUBMARINE
• It has 8 x 533mm torpedo tubes & All tubes can launch torpedoes and four are configured with weapon expulsion system supporting missiles.
Type 214 Submarine

• TORPEDOES: SEEHECHT ( Sea Hake )/DM2A4 mod 4 Torpedo (With eight torpedoes positioned ready & total payload of 16.)
It features an advanced electrical propulsion system and a fiber optic cable for torpedo guidance and communication, which, in conjunction with advanced signals processing and mission logic, makes the torpedo largely countermeasure resistant.
The DM2A4/SeaHake mod 4 is the first torpedo ever to be guided by a fiber optic wire.

AMUR 1650 SUBMARINE has a advantage of supersonic ANTISHIP cruise missile /LACM likes of brahmos over TYPE 214 SUB & that too at capabilty of firing SIX missiles in a salvo,while it gives an extra option Of VLS capability too on demand of customer.While Type 214 sub lacks an effective antiship cruise/lacm having sub sonic SUB HARPOON missile & it can only do that with 4 tubes While AMUR 1650 SUBMARINE has 18 torpedoes capabilty & TYPE 214 SUB has 16 torpedoes capabilty while skhval torpedoes are more faster & has less range compare to DM2A4 mod 4 Torpedo so advantage nullified for amur 1650 sub against TYPE 214 SUB.While mines capabilty AMUR 1650 has the advantage ,but one thing that clearly gives TYPE 214 SUB a unique capabilty is the ability to launch to engage air threats whilst submerged, and to have the first tube-launched missile that does not emerge in a capsule, but is fired directly from the torpedo tubes through IDAS missile, which AMUR 1650 SUBMARINE doesnt have .

SO overall AMUR 1650 SUBMARINE has more fire power than TYPE 214 SUB thanks to brahmos missile & also with VLS capability

10.STEALTH



AMUR 1650 SUBMARINE

• The low noise level of the submarine’s equipment and systemic utilization of advanced acoustic protection facilities provide for reduction of the noise level produced by Amur-1650 by several times than that of other submarines of this class.
Russian Military Forces | Aviation | Navy | Infantry firearms | Communications | Ground systems | Weapon photogallery

• A new technology has been introduced for application of the anti-sonar coating of the new generation “Molniya” (“Lightning”).

Admiralty Shipyards - AMUR Submarine

• The AIP system based on oxygen / hydrogen fuel cells increases the Lada Class submerged endurance from 15 to 45 days. It also reduces noise by avoiding the need for frequent battery recharge by diesel generators.

• An anechoic tile coating on the outer hull reduces noise & a skewed seven-bladed propeller.
http://army.russiansabroad.com/detail.aspx?id=navy&detail=amur1650

• According to Russian reports, it is one of the most quiet and lethal submarines ever built.


TYPE 214 SUBMARINE

• A hull shape, which has been further optimised for hydrodynamic and stealth characteristics, and a low-noise propeller combine to decrease the submarine's acoustic signature.Thus, the hull design and its hydrodynamic form emphasise stealth capabilities, offering good low signature features including both self-generated noise and flow noise and magnetic signature.

U212 / U214 - Naval Technology
Hellenic U214 pics (Greek Turkish Affairs Forum)


• The propelling power is provided by a seven-blade Skew-Back propeller whose extremely low rotation speed prevents cavity and which gener*ates thrust silently even at high speeds.

• SPHINX Radar System is a FMCW transceiver which can't be detected by ESM systems in medium terms. This technology is so called LPI radar, which means "Low probability of intercept". The transmitting power is lower than the power of a mobile phone but the resolution more precise compared to high power Pulse radar. Thales SPHINX radar is a tactical radar, designed for submarines.


• A submarine that uses fuel cells rather than a diesel engine to recharge its batteries produces much less sound while doing and consequently the effective detection range of many of the current passive acoustic sonobuoys is reduced.
Using the Siemens PEM fuel cells enabled AIP system the Type 214 sub on submerged patrol and intercept missions enables the boat to remain submerged for up to 13 days at a speed of 4 kt. Submerged sprint speeds of between 16 and 20+ kt are possible for periods of a few hours several times during a 50 day mission. At a speed of 6 kt the mission range is almost 12,000 n miles. Endurance will be 84 days.The fuel cell works at an operating temperature of 70 to 80ºC, which makes the submarine difficult to detect using external heat sensors.

so both sub are designed specifically bearing in stealth in mind ,while AMUR 1650 SUB has better suface coating & materials
while TYPE 214 SUB has better AIP & LPI sphinx radar along with stealthy hull cross section & shaping which gives Type 214
a edge over amur 1650 in terms of stealth .


CONCLUSION

Well before jumping into conclusion we should take into consideration those negative points which are alleged against TYPE 214 SUBMARINE like
1. Hellenic navy reported many problems
* instability while traveling on the surface, the boat rolls excessively in bad weather.
* Attack periscope vibrates at speeds greater than 3 knots;
* The air-independent propulsion system has lower output power than specified; the unit must be shut down after several hours of sailing due to higher than normal operating temperatures;
* Increased propeller cavitations;
* Seawater leakage into hydraulic systems;
* Problems with the proper function of the flank arrays.
Navy League of the United States - Citizens in Support of the Sea Services
well one may argue that these are deliberate tactics by greece which had bankrupt economy & couldnt afford to procure such sub so that to avoid payment for these subs by giving these excuses.But irony is korea also had some similar problems but
majority of them have been resolved .
? ?? ' ?' - 1 ??
While these problems in the South Korean Type 214s have been reportedly resolved, the noise level has yet to be reduced as promised by HDW. The company was fined $4.1 million by DAPA in February 2008 for ongoing technical problems. In November, a South Korean National Assembly demanded price reductions for the remaining six submarines, arguing that HDW was using the South Korean market to correct faults in the Type 214 to increase the submarine's overall international export potential. It is uncertain if DAPA received a price reduction for the fourth unit when it was contracted to DSME.
Seapower - February 2008.
But all in all many problems in TYPE 214 has been resolved .


LAYMAN'S REPORT CARD


So one can clearly see that TYPE 214 sub excels in allmost all department in comparision to AMUR 1650 sub, leaving aside certain few departments .
Well clear advantage AMUR 1650 SUB has over TYPE 214 sub is
* SIZE
* FIRE POWER (BRAHMOS MISSILE)
* VLS CAPABILITY

Well that criteria is also going to be overcomed as HDW has started development of TYPE 216 SUB to fullfill the criteria of
INDIAN NAVY's PROJECT 75 I programme


TYPE 216 SUB


EXTRA FEATURES

• Bigger size Length: 89 m; Breadth: 8.1 m ;Maximum Draft: 6.6 m

• Double hull design.

• AIP system enabled which gives it endurance of 80 days same as nuclear sub

• Vertical Launch System (2.5 m diameter to deploy cruise missiles or UUV)

• Swimmer Delivery Vehicle (SDV) to deploy special forces

Type 216 / U-216 Conventional Submarine SSK
Submariners World: German - Type 216 / U-216 Conventional Submarine (SSK)

Well India can also make provision to have brahmos fitted into TYPE 216 also ,and later it can also be armed with NIRBHAY Sub launched LACM missile.So with all the extra features & correction of almost all faults from TYPE 214 sub , HDW's next
gen TYPE 216 SUB looks the best eligible contender for INDIAN NAVY's PROJECT 75 I programme.

FROM THE AUTHOR:
I had tried my level best to present & give as much accurate information on both the subs i could find .Well
