Type 209 is a class of diesel-electric attack submarine developed exclusively for export in the late 1960s by Howaldtswerke-Deutsche Werft of Germany. Despite not being operated by the German Navy, the class has been successfully exported to 13 countries with over 60 boats being constructed.
Development
In the early 1970’s, many navies began to need replacements for pre-WWII submarines, aging United States GUPPY, and British units transferred postwar. During this time, few western submarine designs were available for export as most were large, expensive, and designed for the Cold War. Several designs originally built for specific nations were available including the French Daphne Class, British Oberon Class, and the Soviet Foxtrot Class submarines. The design, designated by the German Ministry of Defense as the “Type 209” provided a solution with an adequate armament and reasonable price.
Design
The submarine was designed by Ingenieur Kontor Lübeck (IKL) and is largely based off previous German submarine designs (Type 206) with increased equipment. The design is single hulled and allows the commanding officer to see the entire submarine from the bow to stern while standing at the periscope. Four 120-cell batteries are located forward and aft of the command center in the lower deck and make up about 25% of the ships displacement. Two main ballast tanks with forward and aft trim tanks allow the ship to dive. They are powered by four MTU diesels and four AEG generators. The AEG electric motor is attached directly to a five or seven bladed propeller.
Armaments
Type 209 submarines are armed with 8 bow 533 mm torpedo tubes and 14 torpedoes. The ships used by Greece, South Korea and Turkey are also armed with Sub-Harpoon missiles. Ships used by South Korea can be armed with 28 Mines in place of Torpedoes and Harpoon while the Indian ships can carry 24 Mines externally.
The class can be armed with several different torpedoes depending upon the country. Some torpedoes carried include the SST (Special Surface Target) – Argentina, SUT (Surface and Underwater Target) - Indonesia, and the Mark 24 Tigerfish - Turkey. Brazil’s ships will receive new integrated combat systems from Lockheed Martin to enable the use of the Mark 48 torpedo.
Variants
Five variants of this submarine have been produced: Type 209/1100, Type 209/1200, Type 209/1300, Type 209/1400 and Type 209/1500. The U-209PN ordered by the Portuguese Navy is actually a Type 214.
Several modifications have occurred in the class resulting in these variants including the fitting of newer diesel engines. New air conditioning and electronics features have been added to accommodate orders from South America. The displacement in some variants has increased by nearly 50% in order to install new equipment, modernize accommodations, and extend range.
The Thomson class built for the Chilean Navy has escape hatches fitted in the torpedo and engine room. An additional aft hatch is fitted in the sail with access to the machinery. The boats are fitted with higher masts to compensate for regional ocean wave conditions.
The Tikuna class built by the Brazilian navy is a modified Type 209/1400. The ship is 0.85 m longer and fitted with higher power diesels, different electric motors, batteries, electronics and sensors.
The Type 209/1500 built for India is unique for having an IKL-designed integrated escape sphere. The sphere has accommodations for the entire crew with an eight hour air supply.
It is also possible to upgrade these submarines with the latest air independent propulsion (AIP) systems. The first ships to receive this upgrade will be three ships of the Greeks Poseidon class Type 209/1200 under the Neptune II upgrade program. They will be upgraded by cutting the boat in half aft of the control room and adding a 6 m plug with an 120 kW Siemens AIP system to the ship.
Service
Countries operating the Type 209 include Argentina, Brazil, Chile, Colombia, Ecuador, Greece, India, Indonesia, Peru, South Africa, South Korea, Turkey and Venezuela. All Type 209’s remain in service except for ARA San Luis (S-32) who was stricken in 1997 after an incomplete overhaul.
The first user was the Hellenic Navy which operates four Type 209/1100 and four Type 209/1200 submarines.
The largest operator of the Type 209 is the Turkish Navy which operates six Type 209/1200 submarines (commissioned between 1976 and 1990) and eight Type 209/1400 submarines (commissioned between 1994 and 2007). At present, the Turkish Navy is also the largest operator of German-designed submarines in the world.
Three new Type 209/1400 submarines were delivered to South Africa in 2006, costing $285 million each.

The World of Type 209 Submarines :
A Success On The Export Market
The Birth of Type 209 Sub
30 years ago, in 1967, the shipyard known as Kieler Howaldtswerke signed
a contract in Athens for the delivery of four submarines of approximately
1000t displacemnet to the Royal Hellenic Navy.
Meanwhile, Kieler Howaldtswerke has become Howaldtswerke-Deutsche Werft
AG(HDW), the Greek naval forces call themselves simply the Hellenic Navy,
and the 1000t submarine has officially been designated Type 209 by the
German Ministry of Defence. This contract was the first of many for these
submarines, which have become the most frequently constructed conventionalsubmarine class of the West.
By the early 1970s, many navies found themselves in a position where they
had to replace their old pre-war submarines and those handed over by the
Allied forces after WWII which were becoming outdated. At that time the
French Daphne Class and the British Oberon Class submarines, built for the
respective home navies, were also successfully marketed to foreign navies.
It is remarkable that the Type 209 was a success without the submarines
being used by the German Navy as a point of reference. Subsequent orders
were received. in 1969 for Argentina, 1970 for Peru and Columbia, 1971 for
Turkey and 1972 for Venezuela.
The Superior Features
The design of this submarine was initially based on those built for the Ger-
man Navy, though these were small boats of the same components could be used to equip the larger submarine, partly by doubling the equipment,e.g. installing four diesel generators instead of two. The single hull construction for Type 209 was relatively simple and clearly laid out-it was the idea of Professor Gabler,owner of the engineering and design office Ingenieurkontor Luebeck thatwas largely responsible for the design, to enable the Commanding Officer to see along the entire submarine from the torpedo tubes in the bow to the end of the Engine Room in the stern from a position standing at the periscope. For this reason, the CIC was situated about halfway along the hull.
Forward and aft of this area, the lower deck consisted of large battery rooms
altogether amounting to about 25% of the total displacement. This gave the
submarines good submerged endurance. The low-revolution 5000HP electric motor that acted directly on the propeller shaft enabled high speeds of more than 20 knots to be achieved.
These characteristics-good submerged range, high submerged speed and good handling aspects of the submarine as a whole-are still today the decisive features of the Type 209 submarines. Export success was largely due to the contract in 1969 to build Type 206 submarines for the German Navy awarded on the General Contractor Principle which meant that the construction shipyard as General Contractor was responsible for the correct functioning of the submarine as a whole, including tests and trials and successful firing of exercise Torpedoes. This equipped the shipyard
with the necessary personnel, material resources and experience to assume the role and the responsibility required of the General Contractor for export orders.
Another reason for the success of the Type 209 was that the following major subcontr-actors in Germany were renowned and had the capacity:
Siemens for the propulsion motors and electric control systems
MTU for the diesel engines/generators
Varta and Hagen as experienced battery manufacturers
Maschinenbau Gabler for the snorkel and antennae
Zeiss for the periscopes
Atlas for the sonar systems, and
AEG as torpedo manufacturer.
The only major items subcontracted outside Germany were the radar and fire control systems, and following the line taken by the German governmental procurement authorities,orders were placed with the Dutch company HSA and the French manufacturers Thomson.
With the continued interest of foreign navies in the basic design of the Type 209 submarines leading to more orders, advances in the electronic field proceeded at a very fast pace, making it necessary to adapt the eqiupment of the bats, Furthermore,customers had special requirements, largely due to the desire to use specific sub-contractors for logistic reasons. Thereby, on the one hand familiar equipment was updated, and on the other experience was gained with new subcontractors, For example, fire control systems manufactured by the US company Singer Librascope or by the British
company Ferranti were intalled, whilst Atlas which not only makes sonar systems but also began to specialise in the delivery of complete integrated weapon systems, its "IUS" system were fitted to some of the newest submarines.The incorporation of new equipment of different weapon systems automatically leads to configuration changes elsewhere in the submarine, as the changes imply different space requirements, altered electrical power supplies, other cooling facilities, etc.
The propulsion system initially equipped with suction diesel engines and later with supercharged engines, notably increased performance values. With the assistance of the two earlier mentioned battery manufacturers, battery quality was improved in both low and high power areas, resulting in submerged range and maximum speed being retained in spite of the increase in size of the submarines.
Orders for submarines with mission profiles including operations in the Caribbean or Southeast Asian waters made it necessary to develop and install adequate air-conditioning facilities for crew and electronics, with the appropriate degree of redundancy.
Depending on the specific requirements ordered by different customers, the size of the submarines increased from the original 1000t displacement and in some cases by as much as 50%. The additional size and space were needed to accommodate increases in range, crew living quarters, more electronic equipment and in some instances increased diving depth.The net result has been the emergence of the "Type 209 family" comprising very varied submarines as family members.
One of the constant aims in the continued development of the submarine was the reduction of self-noise. Thanks to the large number of orders that followed each other in an almost annual sequence, every contract profited from the most recent results of research and technology, improvements tested during sea trials which could then be incorporated into the
next project. This achieved surprisingly low radiated noise levels to be achieved both during snorkelling and in submerged cruising.
Many of the tests were possible due to the close and helpful cooperation of the German Ministry of Defence test sites and the use of their special measuring equipment. Although the Type 209 submarines have never been commissioned under the German flag, the German authorities and the Navy have made a great contribution to their success in export orders.
The armaments division of the German Ministry of Defence in Bonn and the Federal Office of Military Technology and Procurement in Koblenz provided inspectors and facilities to monitor the technical concepts and design, and also participated in inspection duties during production on behalf of customers. This is why the submarine was given the official German
fleet name Type 209. On request of customers, the German Navy Submarine Flotilla is willing to conduct basic personnel training and has frequently given further assistance after commissioning to ensure that the crew is fully operational.
Next Generation, Type 212 Technologies for Type 209
Now that the new Type 212 submarine has been developed for the German Navy, naturally the Type 209 submarines would also benefit from new technologies that have been implemented for the first time. One of the main items of interest for other navies will be the airindependent propulsion system using fuel cells. Existing submarines can be modified by the addition of a
specially designed section and the design for new constructions can be updated with an integrated solution. The addition of fuel cell with its fuels H2 and O2 carried on board enablesthe already good submerged range with strong conventional batteries to be increased 4-fold,while retaining this battery at full strength permits an hour submerged at high speed.
Among the modern technologies that can be adopted from the Type 212 design are the permanent magnet(PM) propulsion motor, whichrequires considerably less revolutions at a given speed due to its increased efficiency. Together with the specially designed propeller, this leads to a further reduction in hydredynamic noise.
Since the first Type 209 submarines were ordered, rapid developments especially in the electronics field have resulted in a marked change in performance characteristics in comparison with the boats built today. This can be remedied by modernisation of the older submarines. The first four submarines of this class, ordered 30 years ago for the Hellenic Navy, are being subjected to thorough modernisation, in particular the entire weapon system. Similar measures were taken in the early 90s for the two Venezuelan submarines. Together with the possibility of adding a whole section to accommodate an air-independent propulsion system, there is a wide
range of possibilities of adapting existing boats to future requirements.
Both by modernising existing submarines and due to the many possibilities of introducing new technologies into new constructions, Type 209 promises to remain an interesting competitor on the international market in coming years.

SS-209 Class
The 209 submarine class is designed to destroy hostile submarines, surface ships, protect friendly naval bases, sea shores communications, and carry out reconnaissance missions. The Type 1200 as a member of the Class 209 ensures reliable early detection of hostile warships, including low-noise submarines, owing to a high effective sonar system and low noise feature of the submarine.
With a full submerged displacement of 1200 tons, they are able to dive 250m (850 ft). They are equipped with four MTU diesel engines, providing a maximum speed 21 knots (submerged) and 11 knots (surfaced). They carry eight 533mm/21inch torpedo tubes at the bow, and are armed with 14 torpedoes or 28 mines. This class has plans to update their capaabilities through equiping with a passive towed array sonar. The last three units are armed with Harpoon SSM launching system.
The high energy content in its big battery gives the commanding officer tactical advantages and options. The workload of the crew is considerably reduced by the modern integrated electronic combat system operated via multipurpose consoles, which combine the sonar, navigation information and weapons systems. The incorporation of new equipment or a different weapon system automatically leads to configuration changes elsewhere in the submarine, as the changes imply different space requirements, altered electrical power supplies, other cooling facilities, etc.
The propulsion system was initially equipped with suction diesel engines, but later the transition to supercharged engines was completed and notably increased performance values. With the active assistance of the two already mentioned major battery manufacturers, battery quality was improved in both low and high power areas, retaining good results in submerged range and maximum speed, in spite of the increased size of the submarines.
The diesel-based submarine can navigate at 22 knots (44km) of maximum underwater speed, and 2-month solo operation is possible with 40 members of crew and staff. As it is loaded with detection equipment and battle system, and sub-Harpoons, its war-fighting capabilities are outstanding. The submarines are successfully performing their operations, not detected by enemy submarines in joint operations with the U.S., Australia, Japan and other nations in RIMPAC training, demonstrating its excellence.
Daewoo Shipbuilding enjoyed a virtual monopoly in the nation's submarine industry until early 1999. It built nine 1,200 ton-class submarines in a technical tie-up with HDW since 1991 under the ministry's 10-year submarine project, called "KAA-I."
The Changbogo class submarines are Diesel/Electric propulsion submarines, built under license in South Korea, based on German Type 209-1200. ROKS Changbogo(SS-61), the first ship of this class, was launched on June 1992 by HDW at Kiel in Germany and commissioned on June 1993. The remainder were assembled at Okpo by DAEWOO from material packages transported from Germany. The second and subsequent boats were built by Daewoo Heavy Industries Co. at Koje island, South Korea. ROKS Leesunsin (SS-68), the 7th ship launched on 21 May 1998.
Changbogo class ships were named after a historical Generals' name who related with sea. The lead unit is named after Chang Bo-go [Changbogo], the the admiral of Koryo a 1,000 years ago, who created a maritime Kingdom around Wando, an island situated on the southern tip of the Korean peninsula. Changbogo was a General at the Unified Kindom of Shilla who secured the command of the seaway that linked China, Korea and Japan. Apparently there are intended gaps in the numbering of this class, since there is no SS 064 or SS 070. Number 4 and 0 are reportedly not used by the ROK Navy because they are considered unlucky as these numbers have the same sound as the Korean-read Chinese character meaning death. This numerical nomenclature case is similarly applied to all other military branches as, for example, there is no division number containing the number 4 and so on.
A Korean-built SS-209 class submarine, Lee Chun-ham, participated in Naval Exercise Tandem Thrust conducted in late March 1999 in the vicinity of Guam. The Republic of Korea Navy had asked CINCPACFLT to provide FMS support for the Korean submarine to fire a submarine-launched torpedo at the target ship ex-USS Oklahoma City (a 10,600-ton cruiser). The multi-national participants were also intended to fire a total of 11 Harpoon anti-ship missiles at this target. The Harpoons were to have been fired first, then an FMS-provided transponder was to be installed aboard the ex-USS Oklahoma City or the Korean submarine to launch its torpedo attack. Unfortunately, on exercise day it was impossible to clear the range of commercial shipping necessary to safely conduct the multiple Harpoon attacks, and no Harpoons were fired. The Republic of Korea Navy thus got a rare opportunity to conduct a submarine attack against an undamaged cruiser-sized target. The Korean SS-209 did not disappoint. In firing a single torpedo against the target, a direct hit was made, the target broke into two pieces, and sank in 15 minutes. Well done to CINCPACFLT (N403) for providing the necessary torpedo transponder on very short notice, and well done to the Korean Navy on its highly successful, first ever submarine attack.
The 209 submarine class is designed to destroy hostile submarines, surface ships, protect friendly naval bases, sea shores communications, and carry out reconnaissance missions. The Type 1200 as a member of the Class 209 ensures reliable early detection of hostile warships, including low-noise submarines, owing to a high effective sonar system and low noise feature of the submarine.
With a full submerged displacement of 1200 tons, they are able to dive 250m (850 ft). They are equipped with four MTU diesel engines, providing a maximum speed 21 knots (submerged) and 11 knots (surfaced). They carry eight 533mm/21inch torpedo tubes at the bow, and are armed with 14 torpedoes or 28 mines. This class has plans to update their capaabilities through equiping with a passive towed array sonar. The last three units are armed with Harpoon SSM launching system.
The high energy content in its big battery gives the commanding officer tactical advantages and options. The workload of the crew is considerably reduced by the modern integrated electronic combat system operated via multipurpose consoles, which combine the sonar, navigation information and weapons systems. The incorporation of new equipment or a different weapon system automatically leads to configuration changes elsewhere in the submarine, as the changes imply different space requirements, altered electrical power supplies, other cooling facilities, etc.
The propulsion system was initially equipped with suction diesel engines, but later the transition to supercharged engines was completed and notably increased performance values. With the active assistance of the two already mentioned major battery manufacturers, battery quality was improved in both low and high power areas, retaining good results in submerged range and maximum speed, in spite of the increased size of the submarines.
The diesel-based submarine can navigate at 22 knots (44km) of maximum underwater speed, and 2-month solo operation is possible with 40 members of crew and staff. As it is loaded with detection equipment and battle system, and sub-Harpoons, its war-fighting capabilities are outstanding. The submarines are successfully performing their operations, not detected by enemy submarines in joint operations with the U.S., Australia, Japan and other nations in RIMPAC training, demonstrating its excellence.
Daewoo Shipbuilding enjoyed a virtual monopoly in the nation's submarine industry until early 1999. It built nine 1,200 ton-class submarines in a technical tie-up with HDW since 1991 under the ministry's 10-year submarine project, called "KAA-I."
The Changbogo class submarines are Diesel/Electric propulsion submarines, built under license in South Korea, based on German Type 209-1200. ROKS Changbogo(SS-61), the first ship of this class, was launched on June 1992 by HDW at Kiel in Germany and commissioned on June 1993. The remainder were assembled at Okpo by DAEWOO from material packages transported from Germany. The second and subsequent boats were built by Daewoo Heavy Industries Co. at Koje island, South Korea.

It was false news spread by the Indian media that BN would be receiving 2x Daphne Class attack submarines from PN as a gift. 3x Daphne have been decommissioned and 1x made into a museum as it has the distinction to sink an Indian Navy frigate.

WOW...seems like the Type-209 sub is going to be the new pride of the Bangladesh Navy
Yup, can't wait. I am very excited about it and the purchase of 6x frigates and 16x corvettes.

That's not a very good respose. If you dont have something contructive to say, dont say anything.
