Description
SUT stands for Surface and Underwater Target.{{cite web |last1=Shay |first1=Shaul |title=Egypt's New Modern Submarine Fleet |url=https://www.israeldefense.co.il/en/content/egypts-new-modern-submarine-fleet |website=israeldefense.co.il |publisher=Israel Defense |accessdate=28 May 2019}} It is a dual-purpose weapon that can be launched from surface ships, submarines, and shore positions.{{cite web |title=Indian Navy Scorpene-class Submarines in Sea Trials & SUT Torpedo Firing Test |url=http://www.navyrecognition.com/index.php/news/defence-news/2017/june-2017-navy-naval-forces-defense-industry-technology-maritime-security-global-news/5254-indian-navy-scorpene-class-submarines-in-sea-trials-sut-torpedo-firing-test.html |website=navyrecognition.com |publisher=Navy Recognition |accessdate=28 May 2019}}

A production line was set up in Indonesia with the cooperation of the Indonesian Navy and Indonesian Aerospace to produce the SUT under license. Taiwan received 200 torpedoes from this production line in 1998.

In 2004 the Chilean {{sclass2|Scorpène|submarine|1}} O'Higgins fired a SUT while running at depth during its acceptance tests off Lorient, France.{{cite web |author=Direction des Constructions Navales |title=Torpedo Firing Tests at Depth: Scorpene Scores |url=http://www.defense-aerospace.com/articles-view/release/3/49661/new-chilean-sub-passes-torpedo-trials-(dec.-1).html |website=defense-aerospace.com |publisher=Defense Aerospace |accessdate=30 June 2019 |archive-date=30 June 2019 |archive-url=https://web.archive.org/web/20190630213042/http://www.defense-aerospace.com/articles-view/release/3/49661/new-chilean-sub-passes-torpedo-trials-(dec.-1).html |url-status=dead }}

In 2013 OEM Atlas Elektronik was contracted to upgrade the 64 SUTs remaining in Indian service.{{cite web |last1=Panda |first1=Ankit |title=India To Upgrade Submarine Capabilities |url=https://thediplomat.com/2013/11/india-to-upgrade-submarine-capabilities/ |website=thediplomat.com |publisher=The Diplomat |accessdate=30 June 2019}}
The SUT was the first torpedo fired by the {{sclass|Kalvari|submarine|1||2015}} because of a lack of procurement of planned heavyweight torpedoes. A planned purchase of Black Shark torpedoes fell through because their manufacturer Finmeccanica was blacklisted by the Indian government for procurement corruption.{{cite web |title=Navy may consider German SUT torpedoes for Kalvari submarines, instead of Finmeccanica's 'Black Sharks' |url=https://economictimes.indiatimes.com/news/defence/navy-may-consider-german-sut-torpedoes-for-kalvari-submarines-instead-of-finmeccanicas-black-sharks/articleshow/56690210.cms?from=mdr |website=economictimes.indiatimes.com |publisher=The Economic Times |accessdate=30 June 2019}}

The SUT was originally procured along with the two Hai Lung-class submarines.{{cite web |last1=Sofia Wu |first1=Zep Hu and |title=Taiwan planning to replace aging torpedoes: Defense News |url=http://focustaiwan.tw/news/aipl/201105170048.aspx |website=focustaiwan.tw |publisher=Focus Taiwan |accessdate=30 June 2019}} The torpedoes were procured from the Indonesian production line. In addition to money Taiwan exchanged landing craft and 100,000 tons of rice for the torpedoes.{{cite web |last1=Hsu |first1=Tso-Juei |title=Taiwan's First Indigenous Submarine To Be Launched Ahead Of Schedule |url=https://www.navalnews.com/naval-news/2021/07/taiwans-first-indigenous-submarine-to-be-launched-ahead-of-schedule/ |website=www.navalnews.com |publisher=Naval News |access-date=27 July 2021}}
On September 4, 2003 a war shot SUT fired by a submarine during the Hankuang No. 19 training exercise broke its control wires and went out of control. The torpedo was recovered four hours later from a Yilan County beach. Representatives of the manufacturer traveled to Taiwan to participate in the incident investigation.{{cite web |last1=Hsu |first1=Brian |title=Manufacturers puzzled by navy's errant torpedo |url=http://www.taipeitimes.com/News/taiwan/archives/2003/09/30/2003069842 |website=www.taipeitimes.com |publisher=Taipei Times |accessdate=30 June 2019}} On October 8 the Navy tested a second torpedo with satisfactory results. On October 14 the Navy held a full test in Pingtung County, the first torpedo experienced similar problems to the one on September 4 but the issue was resolved and a second torpedo successfully destroyed the target, a decommissioned Yang-class destroyer.{{cite web |last1=Hsu |first1=Brian |title=Navy relieved as torpedo hits target |url=http://www.taipeitimes.com/News/taiwan/archives/2003/10/15/2003071738 |website=www.taipeitimes.com |publisher=Taipei Times |accessdate=30 June 2019}}
In 2010 the Taiwanese Navy offered a reward to local fishermen for the recovery of a training SUT lost during an exercise.{{cite web |title=Taiwan navy offers £630 reward to fishermen for missing torpedo |url=https://www.telegraph.co.uk/news/worldnews/asia/taiwan/7829460/Taiwan-navy-offers-630-reward-to-fishermen-for-missing-torpedo.html |website=/www.telegraph.co.uk |publisher=The Telegraph |accessdate=30 June 2019}} The SUT will be replaced by the Mk 48 torpedo in Taiwanese service.{{cite web |title=Taiwan budgets $860 million for torpedoes |url=https://www.upi.com/Defense-News/2011/05/26/Taiwan-budgets-860-million-for-torpedoes/18421306407300/ |website=www.upi.com |publisher=UPI |accessdate=30 June 2019}}
