The Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. The original variant (Type 209/1100) was designed in the late 1960s. Despite not being operated by the German Navy, five variants of the class (209/1100, 209/1200, 209/1300, 209/1400 and 209/1500) have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008.

[edit] Development
In the early 1970s, many navies began to need replacements for pre-WWII submarines, aging United States GUPPY conversions, and British units transferred postwar.[6] 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.[7] The design, designated by the German Ministry of Defense as the “Type 209” provided a solution with an adequate armament and reasonable price.[8]
[edit] Design
The submarine was designed by Ingenieur Kontor Lübeck (IKL) and is largely based on previous German submarine designs (in particular the 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.[7] 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.[6] 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.[8] The AEG electric motor is attached directly to a five- or seven-bladed propeller.
[edit] Armaments
Type 209 submarines are armed with 8 bow 533 mm torpedo tubes and 14 torpedoes. The Type 209/1200s used by Greece and South Korea, and the Type 209/1400s used by Turkey are also armed with Sub-Harpoon missiles.[9] Ships used by South Korea can be armed with 28 mines in place of torpedoes and Harpoon missiles; while the Indian ships can carry 24 mines externally.[4]
The class can be armed with a variety of torpedo models depending upon the country. The majority of ships carry SUT - Surface and Underwater Target (Chile, Colombia, Ecuador, Greece, India, Indonesia, South Korea) or the SST - Special Surface Target (Argentina, Peru, Turkey's 209/1200s, Venezuela) torpedoes. Ships can also carry the Mark 24 Tigerfish (Brazil, Turkey's Preveze class 209/1400-T1),[4] DM2A4 (Turkey's Gür class 209/1400-T2), and Mark 37 (Argentina).
Brazil’s ships will receive new integrated combat systems from Lockheed Martin to enable the use of the Mark 48 torpedo.[2]
[edit] 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.[10] The Dolphin class submarines built for the Israeli navy are a based on the Type 209 although heavily modified and enlarged.
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.[11]
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.[12] 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 boat is 0.85 m longer and fitted with higher power diesels, different electric motors, batteries, electronics and sensors.
The Shishumar class built for and by 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.[13]
The Sabalo class built for Venezuela was slightly lengthened during an modernization at HDW in the early 1990s. The increased length is due to the addition of a new sonar dome that is similar to the model found on the German Type 206.[1]
Between 2004 and 2006, the Indonesian Type 209/1300 submarine Cakra underwent a refurbishment by Daewoo Shipbuilding & Marine Engineering in South Korea. The refurbished submarine featured new batteries, overhauled engines, and modernized combat system.[14] Both submarines' existing STN Atlas-Elektronik CSU 3-2 sonar suite were replaced with L-3 ELAC Nautik's LOPAS 8300 passive sonar system and Kongsberg MSI-90U MK2 CMS.[15] In 2009, Daewoo won another order to refurbish Nanggala, which was completed in early 2012.[16]
It is also possible to upgrade these submarines with the latest air independent propulsion (AIP) systems. The first ships to receive this upgrade were to be three ships of the Greek Poseidon class Type 209/1200 under the Neptune II upgrade program.[17] They were to 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.[12][18] The program was canceled in 2009 due to cancellation of the Archimedes Project (Type 214), but not before Okeanos (S118) completed the upgrade.[19] After the Archimedes Project settlement was reached, it was decided that instead of upgrading the remaining two Type 209s, two additional Type 214 ships were to be ordered, but that deal was cancelled by Howaldtswerke-Deutsche Werft.[20][21]
[edit] Chang Bogo upgrades/variant
The South Korean Chang Bogo-class submarines, originally based on Type 209/1200, had reportedly been heavily upgraded from a time early in the 21st century,[22] which if properly undertaken was supposed to include domestic hull stretch augmentation from 1,200 tons to 1,400 tons, and installment of domestically developed Torpedo Acoustic Counter Measures (TACM).[23][24][25] These upgrades could have been affected due to Korean economic problems of the late 1990s, which affected other plans to acquire nine 1,500-ton AIP-equipped boats or upgrade six 1200 boats to 1,500-tons AIP-equipped boats,[23][26][27] although the more ambitious plan to acquire nine 1800-ton Type 214 AIP submarines was preserved and put under progress. Outfitting the submarines with Sub-Harpoon launching capability was a part of the upgrade,[23] and this seems to have been properly carried out by 2002 on at least one submarine. By 2007, Na Daeyong and Lee Eokgi were demonstrated to have the capability.[4][28] In the 2008 RIMPAC the submarine Lee Sunshin also demonstrated its sub-harpoon capability.[29] By 2009 it was reported that nine South Korean-modified 1,400-ton Type 209 submarines were in service with the ROKN.[30][31] As of 2011 they were reported to be 1,200-ton Type 209 submarines.[32][33] They can equip the White Shark heavy torpedo,[25][34][35] and can possibly equip submarine-launched Hae Sung anti-ship missiles later on.[36][37] LIG Nex1 began producing TACM for unspecified submarine types of the ROKN as well, which finished development in 2000.[38][39] AIP and flank-array sonars are planned for future modernizations.[33]
A science documentary by EBS has revealed that Chang Bogo-class submarines undergo major generational overhaul and refit every eight to twelve years.[40] The overhaul and refit involves periodic cutting, complete disassembly, and rewelding of the hull for the upgrade or total replacement of the submarine's old engines, navigational equipment, batteries, and other essential equipment with their modern counterparts.[40] Hull stretch may also have taken place in some of the Chang Bogo-class vessels since the early 2000s, but it has neither been completely confirmed nor denied. Some Chang Bogo-class vessels are demonstrated to have sub-Harpoon launching capability when previously the class was lacking it.
Lithium-ion battery power stacks are being developed to increase the underwater endurance of Chang Bogo-class submarines by two to three times, offering four to five times the power density of Type 209's current lead-acid batteries and as much as twice the power density of Type 214's BZM 120 fuel cells.[41][42]
In December 2011, Daewoo won a contract to build Indonesia three 1,400-ton Chang Bogo-class submarines for $1.07 billion.[43] Construction of the submarines will start in January 2012 for delivery by 2015 and 2016, for commissioning in the first half of 2018. They'll be equipped with torpedoes and guided missiles.[44] The submarines are described to be Korea's original model, bigger and more advanced than Indonesia's refurbished Type 209/1300.[45] Initially the offered submarines were going to be in-service ROKN submarines.[46] The sale will be done without the involvement of German companies.[47] South Korea is currently the only country outside of Germany independently offering the Type 209 for sale. Indonesia was also offered two license built Type 209 submarines manufactured by a group of Turkish (SSM - Undersecretariat for Defense Industries) and German companies (HDW/ThyssenKrupp), a deal reported to be valued at $1 billion.[48] SSM was also offering the leases of Type 209 submarines until new submarines could be completed.[47] The offer has since been superseded by the DSME submarine contract. In early 2012, the Korean defense firm LIG Nex1 exhibited its latest suite of indigenously developed submarine sensors, submarine combat systems, and heavy-weight torpedoes and wire-guided torpedoes in Indonesia for potential use by the Indonesian navy's submarine forces.[49]
[edit] 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 209s remain in service except for ARA San Luis (S-32) which was stricken in 1997 after an incomplete overhaul and Glavkos S-110 decommissioned in 2011. Iran had an order for six Type-209 submarines that was cancelled by Khomeini in 1979.[50]
The first user was the Hellenic Navy which purchased 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 1989) 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.
Type 209s are often supplemented with other submarine designs or are scheduled to be replaced by them. Argentina received two TR-1700 class submarines (Santa Cruz class) during the 1980s. Ten Kilo class submarines were purchased by India in the 1980s and 90s (Sindhughosh class submarine), along with Akula class submarine INS Chakra in 2011. Two Scorpène class submarines have been commissioned by Chile, while Brazil has four and India has six ships ordered or under construction. Nine Type 214 submarines (Son Won-il class) are commissioned, building, or planned by South Korea to supplement its force, while Greece is replacing its aging Glaukos class with four Type 214 submarines (Papanikolis class), and Turkey will be replacing early Atılay class ships with six Type 214 submarines.[51]
During the Falklands War the Argentinian Type 209/1200 submarine "San Luis" fired some wire guided torpedos at the British fleet (some sources claim one target was carrier Invincible and its escorts, but this is not confirmed). The inexperienced operators accidentally reversed the polarity in the electric gyroscopes during maintenance so the torpedos could not be steered.[52]
