The '''REMUS''' (Remote Environmental Monitoring UnitS) series are [[Engineering:Autonomous underwater vehicle|autonomous underwater vehicle]]s (AUVs) made by the [[Organization:Woods Hole Oceanographic Institution|Woods Hole Oceanographic Institution]] and designed by their Oceanographic Systems Lab (OSL). More recently REMUS vehicles have been manufactured by the spinoff company Hydroid Inc, which was a wholly owned subsidiary of [[Company:Kongsberg Maritime|Kongsberg Maritime]].<ref name=":0">{{Cite web|url=http://www.hydroid.com/products|title=Marine Robots (AUVs) {{!}} Hydroid, Inc.|website=www.hydroid.com|access-date=12 June 2016}}</ref> Hydroid was acquired by [[Company:Huntington Ingalls Industries|Huntington Ingalls Industries]] (HHI) in March 2020.<ref name=HHI>{{Cite web|url=https://hii.com/news/huntington-ingalls-industries-closes-the-acquisition-of-hydroid-inc/|title=HUNTINGTON INGALLS INDUSTRIES CLOSES THE ACQUISITION OF HYDROID INC.|website=hii.com|access-date=28 April 2023|date=26 March 2020}}</ref>
The series are designed to be low cost, they have shared control software and electronic subsystems and can be operated from a [[Engineering:Laptop|laptop]] computer.<ref name=WHOIREMUSmain>{{cite web|title=REMUS|url=http://www.whoi.edu/main/remus|publisher=Woods Hole Oceanographic Institution|access-date=9 July 2012|}}</ref> They are used by civilians for [[Earth:Seafloor mapping|seafloor mapping]], underwater [[Engineering:Surveying|surveying]], and search and recovery as well as by several navies for mine countermeasures missions.

==Models==
There are four variants of the REMUS, all are torpedo-shaped vessels with reconfigurable sensors.

===REMUS 6000===
The largest model is the REMUS 6000 at {{convert|3.84|m|ft}} long and {{convert|71|cm|in}} in diameter; it is named after its maximum diving depth of 6000m.<ref name=WHOIREMUS6000spec>{{cite web|title=REMUS 6000|url=http://www.whoi.edu/page.do?pid=38144|publisher=Woods Hole Oceanographic Institution|access-date=9 July 2012}}</ref> It can travel at speeds of up to {{convert|5|kn|kph}} and has an endurance of up to 22 hours.<ref name=WHOIREMUS6000spec /> It was developed through cooperation between the Naval Oceanographic Office, the Office of Naval Research, and the Woods Hole Oceanographic Institution (WHOI).<ref>{{cite web |title=AUV System Spec Sheet |url=http://auvac.org/configurations/view/40 |website=auvac.org |publisher=Autonomous Undersea Vehicle Application Center |access-date=8 January 2019}}</ref>

In 2018 the [[Organization:Japan Agency for Marine-Earth Science and Technology|Japan Agency for Marine-Earth Science and Technology]] (JAMSTEC) received an order of New Generation REMUS 6000 AUVs. The New Generation REMUS 6000 is based on the legacy REMUS 6000 platform with "a modular architecture that allows for the addition of multiple payloads including customer sensor packages, forward fins and additional battery sections.”<ref>{{cite web |title=Hydroid Receives Order for New Generation REMUS 6000 AUV from Japan Agency for Marine-Earth Science Technology (JAMSTEC) |url=https://www.prnewswire.com/news-releases/hydroid-receives-order-for-new-generation-remus-6000-auv-from-japan-agency-for-marine-earth-science-technology-jamstec-300752637.html |website=prnewswire.com |publisher=prnewswire.com |access-date=8 January 2019}}</ref> Hydroid also claims that the New Generation model has increased endurance.

===REMUS 600===
The midsized REMUS 600 was previously known as the REMUS 12.75, so called due to its {{convert|12.75|in|cm|adj=on}} diameter. It was renamed to the 600 to correspond to the maximum depth at which it can operate (600m).<ref name=WHOIREMUS600pic>{{cite web|title=REMUS in Photos|url=http://www.whoi.edu/page.do?pid=38175&tid=4142&cid=39133&i=9|publisher=Woods Hole Oceanographic Institution|access-date=9 July 2012}}</ref> The US Navy derivative of this platform is designated Mk 18 Mod 2 “Kingfish."<ref>{{cite web |title=Mk 18 Mod 2 Kingfish configuration |url=http://auvac.org/configurations/view/225 |website=AUVAC.com |publisher=AUVAC |access-date=6 July 2018}}</ref> The Mk 18 Mod 2 is equipped with side-scan sonar, a downward-looking video camera, ADCP, [[Engineering:GPS|GPS]], beam attenuation meter (BAM) to measure [[Biology:Turbidity|turbidity]], and a conductivity temperature depth (CTD) sensor.<ref name=RFP>{{cite report |author=William W Sprigg |date=September 12, 2018 |title={{sic|Envirom|ental|nolink=y}} Services for Unmanned Maritime Systems|url=https://e-commerce.sscno.nmci.navy.mil/Command/02/ACQ/navhome.nsf/homepage?readform&db=navbusopor.nsf&whichdoc=25E926C25313510C862582F90076CF18&editflag=0 |publisher=SPAWAR Contracts Directorate Office |page= |docket=N66001-18-T-2006 |access-date=September 18, 2018}}</ref> It can travel at speeds of up to {{convert|5|kn|kph}} and has an endurance of up to 70 hours at its standard cruising speed of {{convert|3|kn|kph}}.<ref name=WHOIREMUS600pic />

===REMUS 100=== 
[[File:Katanpää Lippujuhlan päivän kalustoesittely 2016 2 REMUS 100.JPG|thumb|REMUS 100 of the Finnish Navy]]
The REMUS 100 takes its name from its max operating depth of 100 meters.<ref name=":0" /> The US Navy operates a derivative of the REMUS 100, in addition to the standard REMUS 100, designated Mk 18 Mod 1 “Swordfish”.<ref name=100spec>{{cite web |title=Swordfish Mk 18 Mod 1 configuration |url=http://auvac.org/configurations/view/226 |website=auvac.com |publisher=auvac |access-date=6 July 2018}}</ref> It can travel at speeds of up to {{convert|5|kn|kph}} and has an endurance of up to 22 hours at its standard cruising speed of {{convert|3|kn|kph}}.<ref name=100spec />

===REMUS M3V=== 
The REMUS M3V (Micro 300 Meter Rated Vehicle) is the smallest in the range and is designed to fit the A-type sonobouy design envelope (91.5 x 12.4&nbsp;cm). The M3V can travel at 10 knots and dive to 300 meters, apparently uniquely among the REMUS family the M3V can be airdropped.<ref>{{cite web |last1=Leoni |first1=Victoria |title=New undersea drones are smaller, cheaper and can be refueled deep under water |url=https://www.defensenews.com/digital-show-dailies/navy-league/2018/04/10/new-undersea-drones-are-smaller-cheaper-and-can-be-refueled-deep-under-water/ |website=defensenews.com |publisher=Defense News |access-date=18 January 2019|date=2018-04-11 }}</ref>

The [[Organization:University of Hawaii at Manoa|University of Hawaii at Manoa]] operates a REMUS 100 equipped to measure salinity, temperature, currents, bathymetry and water quality parameters.
