==History==
First budgeted in July 1989 and ordered in January 1990, by November the order for the submarines was cancelled. This was due to budget reallocation aimed at countering Iraqi threats made against Israel following the Iraqi invasion and annexation of neighboring Kuwait during the leadup to the [[1991 Gulf War]]. Funding for the first two boats (''Dolphin'' and ''Leviathan'') was fully subsidized by the [[Germany|German government]] to restart the construction program and the third (''Tekumah'') received a 50% subsidy. During the [[Gulf War|First Gulf War]], it was revealed that German firms had assisted Iraq with modernizing its ballistic missile and chemical weapon programs, thanks in part to lax enforcement by [[Bundeszollverwaltung|German customs]], in violation of the [[Missile Technology Control Regime]] protocols which West Germany had acceded to in 1987.<ref>{{Cite web|url=https://www.idsa-india.org/an-sep9-5.html|archive-url=https://web.archive.org/web/20001012045446/http://idsa-india.org/an-sep9-5.html|url-status=usurped|archive-date=October 12, 2000|title=Missile Technology Control Regime: Impact Assessment|website=www.idsa-india.org}}</ref> These enhanced missiles brought Israeli cities into Iraqi targeting range for the first time, and the Iraqi weapons research program included factories and necessary supplies for the creation of weaponized [[Sulfur mustard|mustard]] and [[Nerve agent|nerve gas]].<ref>{{cite web|url=https://www.theguardian.com/politics/2003/mar/06/uk.iraq|title=Britain's dirty secret|author=David Leigh|work=The Guardian|date=6 March 2003|access-date=1 May 2016}}</ref><ref name="iraqwatch.org">{{cite web |url=http://www.iraqwatch.org/profiles/missile.html |title=Iraq's Missiles" a Brief History |publisher=IraqWatch.org |access-date=25 December 2014 |archive-url=https://web.archive.org/web/20150218050214/http://www.iraqwatch.org/profiles/missile.html |archive-date=18 February 2015 |url-status=dead |df=dmy-all }}</ref> Though not a belligerent in the Gulf War, Israeli cities were nevertheless bombarded by these upgraded Iraqi missiles.<ref>{{cite web |url=http://www.mfa.gov.il/mfa/aboutisrael/history/pages/the%20gulf%20war%20-%201991.aspx |title=The Gulf War (1991) |publisher=Israel Ministry of Foreign Affairs |access-date=17 January 2014 |url-status=dead |archive-url=https://web.archive.org/web/20131213015723/http://www.mfa.gov.il/mfa/aboutisrael/history/pages/the%20gulf%20war%20-%201991.aspx |archive-date=13 December 2013 }}</ref><ref>{{cite news |url=http://news.bbc.co.uk/onthisday/hi/dates/stories/january/18/newsid_4588000/4588486.stm |title=On This Day: January 18 – 1991: Iraqi Scud missiles hit Israel |work=BBC |access-date=25 December 2014}}</ref> To compensate Israel for war-related damage and economic losses<ref name="iraqwatch.org" /><ref name="reuters-20091125">{{cite news |url=https://www.reuters.com/article/arms-israel-germany-idUSGEE5AN12E20091125 |title=Israel seeks discount on two German warships |first=Dan |last=Williams |date=25 November 2009 |work=Reuters |access-date=25 December 2014}}</ref> and keep German shipyards occupied with a high profile project in the post Cold War defense spending downturn,<ref>{{cite web |url=http://dspace.cigilibrary.org/jspui/bitstream/123456789/24800/1/European%20defense%20industry.pdf?1 |archive-url=https://web.archive.org/web/20131111193710/http://dspace.cigilibrary.org/jspui/bitstream/123456789/24800/1/European%20defense%20industry.pdf?1 |url-status=dead |archive-date=2013-11-11 |title=The European Defense Industry: Prospects for Consolidation |publisher=UNISCI Discussion Papers |last=Guay |first=Terrence |date=October 2005 |access-date=25 December 2014 }}</ref><ref name="globalsec">{{cite web|url=http://www.globalsecurity.org/wmd/world/israel/sub.htm |title=Israel: Submarines |access-date=25 July 2011 |website=[[GlobalSecurity.org]] |url-status=dead |archive-url=https://web.archive.org/web/20110604012228/http://www.globalsecurity.org/wmd/world/israel/sub.htm |archive-date=June 4, 2011 }}</ref> then [[Chancellor of Germany (Federal Republic)|Chancellor of Germany]] [[Helmut Kohl]] approved an assistance package to German industry including the construction of two ''Dolphin''-class submarines.<ref name="did-20060822">{{cite web |url=http://www.defenseindustrydaily.com/germanisraeli-dolphin-aip-sub-deal-finalized-02552/ |title=German-Israeli Dolphin AIP Sub Contract Signed |publisher=Defense Industry Daily |date=22 August 2006 |access-date=25 December 2014}}</ref><ref name="Dolphin-Project">{{cite web |url=http://submarines.dotan.net/dolphins/project.htm |title=The Dolphin Project |first1=Captain(Res.)

The names [[HMS Truncheon (P353)|''Dolphin'']] and [[HMS Turpin (P354)|''Leviathan'']] hail from the retired Israeli WWII-era submarines of the [[British T-class submarine|British T class]]; the third boat ''Tekuma'' (translation: Revival) commemorates {{INS|Dakar||2}}, the third Israeli boat of the T class which was lost in 1968 with all Israeli crew in the Mediterranean Sea during delivery.

In 2016, it was revealed that a new sonar developed by [[Rafael Advanced Defense Systems]] had begun to be fitted on all ''Dolphin'' submarines in the last two years. The new capabilities provided to the ''Dolphin'' submarines by the Israeli sonar also include detection of vessels with a low noise signature. The algorithms used in the sonar systems enable it to ignore many of the noises that can disrupt the range of the systems' activity, while detecting very distant noises.<ref>[http://www.globes.co.il/en/article-israel-navy-to-fit-upgraded-sonar-on-submarines-1001160259 Israel Navy to fit upgraded sonar on submarines] 09/11/2016, 20:58, Yuval Azulai</ref>

The ''Dolphin'' class uses the ISUS 90-1 TCS weapon control system supplied by STN [[Atlas Elektronik]], for automatic sensor management, fire control, navigation, and operations. The installed radar warning receiver is a 4CH(V)2 Timnex electronic support measures system, scanning from 5{{nbsp}}GHz to 20{{nbsp}}GHz frequency bands and able to pinpoint radar sites with accuracy between 5 and 10 degrees of angle (depending on frequency).<ref>{{cite journal |url=http://www.harpoonhq.com/waypoint/articles/Article_042.pdf |last=Friedman |first=Norman |title=Up Periscope Up antenna |journal=Waypoint |date=February 2003 |access-date=25 December 2014 |archive-date=26 December 2014 |archive-url=https://web.archive.org/web/20141226042612/http://www.harpoonhq.com/waypoint/articles/Article_042.pdf |url-status=dead }}</ref>  The surface search radar is an [[Elta Systems|Elta]] unit operating on [[I band (NATO)|I band]]. The sonar suite includes the advanced Atlas Elektronik CSU 90 hull-mounted passive and active search and attack sonar. The PRS-3 passive ranging sonar is also supplied by Atlas Elektronik, the flank array is a FAS-3 passive search sonar. A notable design feature is the prismatic hull cross-section and smoothly faired transitions from the hull to the sail, improving the boat's stealth characteristics. The ship and internal features are constructed of nonmagnetic materials, significantly reducing the chances of it being detected by magnetometers or setting off magnetic naval mines. The submarines have two Kollmorgen periscopes.<ref name="naval-technology" /> The ''Dolphin''s can mount an external special forces hangar aft of their sail.<ref>{{cite web |last1=Sutton |first1=H I |title=Image reveals Shayetet-13's submarine hangar |url=http://www.hisutton.com/Israeli-Navy-Dolphin-Class-Submarine-with-Special-Forces-Hangar.html |website=www.hisutton.com |publisher=HI Sutton |access-date=16 October 2020}}</ref>

The propulsion system provides a speed of {{convert|20|kn}} submerged and a snorkeling speed of {{convert|11|kn}}. The hull is rated for dives up to {{convert|350|m|abbr=on}}. The maximum unrefuelled range is {{convert|8000|nmi}} traveling on the surface at {{convert|8|kn}} and over {{convert|400|nmi}} at {{convert|8|kn}} submerged; they are designed to remain unsupplied for up to 30 days on station.<ref name="naval-technology" />

[[File:I.n.s. dolfin-03.JPG|thumb|right|150px|INS ''Dolphin'' - a ''Dolphin''-I submarine, seen here in 2010.]]

According to news reports the submarines are normally based in the Mediterranean,<ref>{{cite news |url=https://www.reuters.com/article/newsOne/idUSTRE5621XZ20090703 |title=Israeli sub sails Suez, signaling reach to Iran |last=Williams |first=Dan |date=3 July 2009 |work=Reuters |access-date=25 December 2014}}</ref> although one ''Dolphin'' class was sent to the [[Red Sea]] for exercises, briefly docking at the naval base of [[Eilat]] in June 2009, which Israeli media interpreted as a warning to Iran.<ref>{{cite news |url=http://www.nzherald.co.nz/world/news/article.cfm?c_id=2&objectid=10582762 |title=Israel sends sub as 'a warning' |date=6 July 2009 |newspaper=The New Zealand Herald |access-date=2012-07-06}}{{dead link |date=July 2012}}</ref> In 2009 the Israeli newspaper [[Haaretz]], quoting an Israeli defence official, reported that the very small Eilat naval station is unsuited strategically to base the ''Dolphin''-class boats, specifically noting the tight entrance of the [[Gulf of Aqaba]] at the [[Straits of Tiran]] as one held by potential adversaries including [[Saudi Arabia]] on the east and the demilitarized Egyptian Sinai to the west. Eilat is a {{convert|10|km|abbr=on}} strip of coast between Egypt and Jordan. According to The London Sunday Times, the Israeli Navy decided in May 2010 to keep at least one submarine equipped with nuclear-tipped SLCM there permanently as a deterrent in response to rumored ballistic missiles moved from Syria to Lebanon.<ref name="times-20100530" />

If the boats are based at the larger Haifa naval base, access to the Persian Gulf area either requires openly sailing on the surface through the Egyptian controlled [[Suez Canal]] as permitted in the [[Egypt–Israel peace treaty]] or a long voyage sailing around Africa. According to the [[Convention of Constantinople]] signed by the ruling great powers of the time including the UK, France, and the Ottoman Empire on March 2, 1888; "The Suez Maritime Canal shall always be free and open, in time of war as in time of peace, to every vessel of commerce or of war, without distinction of flag."<ref>{{sourcetext|source=Constantinople Convention of the Suez Canal}}</ref>  Denied crossing at the Suez Canal and blockade of the Straits of Tiran occurred in both in 1956 and 1967 leading to Israel twice seizing the Sinai to break the blockade.<ref name="Oren">{{cite book |first=Michael B. |last=Oren |title=Six Days of War: June 1967 and the Making of the Modern Middle East |location=Oxford |publisher=Oxford University Press |year=2002 |isbn=0-19-515174-7 |url-access=registration |url=https://archive.org/details/sixdaysofwarjune0000oren }}</ref> The [[Egypt–Israel peace treaty]] allows for the free passage of Israeli vessels through the [[Suez Canal]], and recognizes the [[Strait of Tiran]] and the [[Gulf of Aqaba]] as international waterways. Even if a Red Sea or Indian Ocean base is unavailable other nations have used [[submarine tender]]s, ships that resupply, rearm, and refuel submarines at sea, when nearby friendly bases are unavailable.

According to two contradictory Sudanese media reports, in November or December 2011 two Israeli air raids against [[Gaza Strip|Gaza]]-bound weapon smugglers in [[Sudan]] were accompanied by Israeli submarine activity off the Sudanese coast.<ref>{{cite news |url=http://www.haaretz.com/news/diplomacy-defense/reports-in-sudan-israel-struck-two-weapons-convoys-in-past-month-1.403521 |newspaper=[[Haaretz]] |title=Reports in Sudan: Israel struck two weapons convoys in past month |last1=Issacharoff |first1=Avi |last2=Harel |first2=Amos |date=25 December 2011 |access-date=25 December 2014}}</ref><ref>{{cite news |url=http://www.jpost.com/MiddleEast/Article.aspx?id=250872 |title=Sudanese media report on Israeli air strikes |first1=Joanna |last1=Paraszczuk |first2=Yaakov |last2=Katz |newspaper=The Jerusalem Post |date=25 December 2011 |access-date=25 December 2014}}</ref> The Sudanese government claims no strikes took place.

In February 2012, [[Ynet]], the online version of the Israeli newspaper ''[[Yedioth Ahronoth|Yediot Achronot]]'', reported that for security reasons applicants for the submarine service with [[Multiple citizenship|dual citizenship]] or citizenship in addition to Israeli, which is common in Israel with a relatively high percentage of [[Aliyah|olim]] (immigrants), must officially [[Renunciation of citizenship|renounce all other citizenships]] to be accepted into the training program.<ref>{{cite news |url=http://www.ynetnews.com/articles/0,7340,L-4187233,00.html |title=IDF submarine fleet bans dual citizenship |first=Yoav |last=Zitun |newspaper=[[Ynet]] |date=8 February 2012 |access-date=25 December 2014}}</ref>

[[Arutz Sheva|Israel National News]] and [[The Jerusalem Post]] both had articles on Sunday, July 14, 2013, which quoted that day's London [[The Sunday Times|Sunday Times]] saying that the July 5 Israeli missile strike against the Syrian port of [[Latakia]], previously reported by CNN as an [[Israel Air Force]] strike, was made in coordination with the United States, and long range missiles were launched from a ''Dolphin''-class submarine. The attack targeted newly unloaded Russian-made [[P-800 Oniks|Yakhont]] long range high performance anti-ship missiles and associated radars.<ref>{{Cite web |url=http://www.debka.com/article/23116/ |title=US to media: Israel struck Latakia arsenal last week.

In December, 2020, an IDF submarine transited the Suez Canal and the Red Sea, en route to the Persian Gulf in possible preparation for any Iranian retaliation over the November assassination of a senior Iranian nuclear scientist, [[Mohsen Fakhrizadeh]].<ref>{{cite news | url=https://www.washingtonpost.com/world/middle_east/iran-israel-fakhrizadeh-nuclear-assassination/2020/12/23/fca9e0fe-44e8-11eb-ac2a-3ac0f2b8ceeb_story.html | title=Israel deploys submarine to Persian Gulf in message of deterrence to Iran | newspaper=The Washington Post | date=23 December 2020 | access-date=24 December 2020}}</ref>

==Speculation regarding INS Drakon==
[[file:INS Drakon, Israeli submarine of German submarine class Dolphin-AIP (modified version).jpg|thumb|INS Drakon with larger sail]]
Although unconfirmed by either the German or Israeli government, there was speculation that the Drakon would be longer than previous boats of its class and might have new weapon capabilities, including a vertical launch system (VLS).<ref>{{cite web|url=https://www.navalnews.com/naval-news/2022/01/israels-submarine-secret-new-dolphin-class-boat-could-have-vls/|title=Israel's Submarine Secret: New Dolphin-IIs Could Have VLS|date=19 January 2022|website=Naval News |last=Sutton |first=H.I. |access-date=15 August 2023}}</ref> Illustrations released by ThyssenKrupp Marine Systems (TKMS), the prime contractor, show it with an enlarged sail and distinctly changed hullform. TKMS went on to describe the Dakar as “a completely new design, which is to be specifically engineered to fulfill the operational requirements of the Israeli Navy.” <ref>{{cite web|url=https://www.thedrive.com/the-war-zone/43951/our-first-look-at-israels-new-dakar-class-submarine-reveals-a-very-peculiar-feature|title=Our First Look At Israel's New Dakar Class Submarine Reveals A Very Peculiar Feature|date=20 January 2022 }}</ref>

The boat was reported to have been taken out of the water but re-launched again in August 2023. With the re-launch, photographs confirmed a much larger sail which might accommodate its vertical launch missile silos, if these fitted to the vessel.<ref>{{cite web|url=https://www.navalnews.com/naval-news/2023/08/israel-launches-new-submarine-first-in-world-with-modern-missiles-in-sail/ |title=Israel Launches New Submarine, First In World With Modern Missiles In Sail |date=14 August 2023|website=Naval News |last=Sutton |first=H.I. |access-date=15 August 2023}}</ref> According to analysis conducted by Matus Smutny, the sail "could also contain a special release compartment for unmanned underwater vehicles (UUVs), aerial drones, and/or other special operations and intelligence-gathering equipment. The revised sail could also be related to some kind of proof-of-concept for technology to be used in the upcoming [[Dakar-class submarine|Dakar class]]".<ref>{{cite web|url=https://www.thedrive.com/the-war-zone/new-israeli-submarines-big-sail-seen-in-images |title=Latest Israeli Submarine's Big Sail Seen In New Images |date=3 August 2023|website=The Drive |last=Smutny |first=Matus |access-date=15 August 2023}}</ref>
