'''Immediate Support Vessel''' (ISV) is a type of light and armed [[patrol boat]] of the [[Indian Navy]].

==Design and description==
The ISVs have been designed and built by SHM Shipcare, Abu Dhabi Ship Building (ADSB) and Rodman 78 of Spain, for the patrol boat requirement of India's [[Oil and Natural Gas Corporation]] (ONGC) and the Indian Navy.<ref name=toi30j14/><ref name=oki/><ref name=mbiz>{{cite web|title=DIAB core materials used to Build Immediate Support Vessels (ISVs) of ONGC by Indian Boat Builder|url=http://www.marinebiz360.com/knowledge_details.php?id=19|publisher=Marine Biz|accessdate=5 June 2014}}</ref> and were funded by ONGC.<ref>{{cite news|title=Three Immediate Support Vessels commissioned into Navy|url=http://economictimes.indiatimes.com/news/politics-and-nation/three-immediate-support-vessels-commissioned-into-navy/articleshow/45983774.cms|accessdate=23 January 2015|agency=The Economic Times|date=22 January 2015}}</ref>

The ISVs are made of [[fiberglass]] reinforced hulls, and are capable of operating in [[sea state]] 6 conditions. They are fitted with two Caterpillar engines, each of {{convert|1600|hp|abbr=on}}, which enables top speed of 40 knots using [[Water jet (propulsion)|water jet propulsion]], and a radius of operation of 500 nautical miles. The boats are armed with heavy and light machine guns, and also carry modern navigational and communication sensors and equipment for day and night surveillance. They also carry an inflatable Gemini boat to enable rapid insertion or extraction of the Indian Navy's [[MARCOS]] for search and rescue, law enforcement and maritime patrol. The patrol boats are commanded by an officer of the rank of [[Lieutenant]] and have a crew of six sailors, and can carry a total of 20 people on board.<ref name=SHM/><ref name=toi30j14/><ref name=oki/><ref name=mbiz/><ref name=tniex5j/>

==Service history==
One Immediate Support Vessel deployed at [[Bombay High]] fired at a fisherman in a boat. The incident occurred on Sunday, May 17, 2015, in the Arabian Sea, around 80 km off [[Mumbai]]. The boat had strayed into the high security and prohibited area of an offshore oil rig, and anchored close to an oil platform. According to the navy's report, "despite repeated warnings, the boat refused to move out of the prohibited area, which is when the warning shots were fired into the water. One round deflected on hitting the water and hit a fisherman in a boat." He was evacuated in a helicopter and taken to a hospital, where is condition was reported to be stable.<ref>{{cite news|title=Indian Navy admits shooting at 'trespassing' fisherman|url=http://www.hindustantimes.com/india-news/indian-navy-admits-shooting-trespassing-fisherman/article1-1348326.aspx|archive-url=https://web.archive.org/web/20150518100210/http://www.hindustantimes.com/india-news/indian-navy-admits-shooting-trespassing-fisherman/article1-1348326.aspx|url-status=dead|archive-date=18 May 2015|accessdate=22 May 2015|publisher=The Hindustan Times|date=May 18, 2015}}</ref>
