Question: What does INS Nipat have to do with the Indian Navy?
Context: The Indian Navy currently operates twenty-one air squadrons. Of these, ten operate fixed-wing aircraft, eight are helicopter squadrons and the remaining three are equipped with unmanned aerial vehicles (UAV).  Building on the legacy inherited from the Royal Navy prior to Indian independence, the concept of naval aviation in India started with the establishment of Directorate of Naval Aviation at Naval Headquarters (NHQ) in early 1948.  Later that year officers and sailors from the Indian Navy were sent to Britain for pilot training.  In 1951, the Fleet Requirement Unit (FRU) was formed to meet the aviation requirements of the navy.  On 1 January 1953, the charge of Cochin airfield was handed over to the navy from the Directorate General of Civil Aviation.  On 11 March, the FRU was commissioned at Cochin with ten newly acquired Sealand aircraft.  The navy's first air station, INS "Garuda", was commissioned two months later.  From February 1955 to December 1958, ten Firefly aircraft were acquired.  To meet the training requirements of the pilots, the indigenously developed HAL HT-2 trainer was inducted into the FRU.  On 17 January 1959, the FRU was commissioned as Indian Naval Air Squadron (INAS) 550, to be the first Indian naval air squadron.  In the following two years, three more naval air squadrons—INAS 300, INAS 310 and INAS 551—were commissioned.  The first two operated from the newly purchased aircraft carrier INS "Vikrant" flying Sea Hawks and Alizés, whereas the latter one, equipped with Vampires, was used for training purposes. INS Andamans is a Nicobar class troop ship.  These large multi-role troop ships were converted from merchant ships which were originally ordered by the Ministry of Shipping for service with the Shipping Corporation of India that were later acquired by the Indian Navy for troop transport duties.  The ship has large davits for Landing Craft Vehicle Personnel (LCVP) and also features a high bridge forward, funnel in the aft, and a helicopter platform at the stern.  This makes the vessel suitable for general purpose roles, other than just troop transport.  The INS Andamans should not be confused with INS Andaman (P74), the Petya-class frigate that was lost in the Bay of Bengal in 1990 during a naval exercise, which were designated as "Arnala"-class corvette s in Indian Navy due to their small size. INS "Buland" is a 25 tonne bollard pull tugboat built by Hindustan Shipyard for the Indian Navy.  It is the third ship of the series of 25-ton bollard pull tugboats after INS "Balwan" and INS "Sahayak" that were built within 10 months and delivered in January 2016 in time for International Fleet Review 2016.  After the sea trials, the ship was flagged off by Commander A.S. Mitra (retired), Director (Shipbuilding) on November 15, 2016 and joined the Indian Navy at its home port of Port Blair. INS "Tillanchang" is a patrol vessel of the Trinkat class patrol vessel of Indian Navy designed and constructed by Garden Reach Shipbuilders and Engineers in Kolkata, West Bengal.  "Tillanchang" is named after Tillangchong Island sometimes also called Tillanchang and was commissioned into the Indian Navy on 17 March 2001.  She was transferred to Maldivian Coast Guard on 16 April 2006 as CGS "Huravee".  As part of the transfer, technical and material assistance was provided by the Indian Navy for a period of three years.  The Indian Navy also stationed a team of personnel for a preliminary period and on-the-job training of the Maldivian crew. The following ships of the Indian Navy have been named INS "Nipat": INS "Balshil" is a "Bhim" class tugboat currently in service with the Indian Navy.  The ship was delivered to the Indian Navy ahead of schedule.  INS "Balshil" enhances the capability of the yard in berthing bigger ships of the Indian Navy.  The tugboat also has capacity to carry cargo. The Indian Navy (IN; : "Bhāratīya Nau Senā") is the naval branch of the Indian Armed Forces.  The President of India is the Supreme Commander of the Indian Navy.  The Chief of Naval Staff, a four-star Admiral, commands the navy. INS "Viraat" (Sanskrit: Virāṭa meaning "Giant") was a "Centaur"-class aircraft carrier of the Indian Navy.  INS "Viraat" was the flagship of the Indian Navy before  was commissioned in 2013.  The last British-built ship serving with the Indian Navy, she was the oldest aircraft carrier in service in the world.  The ship was completed and commissioned in 1959 as the Royal Navy's HMS "Hermes" , and decommissioned in 1984.  It was sold to India in 1987.  INS "Viraat" was commissioned into the Indian Navy on 12 May 1987, and served for almost 30 years. INS "Chakra" is a 8140 t Project 971 (or Project 518; NATO: "Akula"-class submarine ) nuclear-powered attack submarine.  The construction of the Nerpa submarine was started in 1993, but was then suspended due to lack of funding.  The Indian Navy sponsored the building and sea trials of the submarine provided it was given to the Indian Navy on lease for 10 years.  It was launched as "K-152 Nerpa" in October 2008 and entered service with the Russian Navy in late 2009.  The submarine was leased to the Indian Navy in 2011 after extensive trials, and was formally commissioned into service as INS "Chakra" II at a ceremony in Visakhapatnam on 4 April 2012.  The INS "Chakra" joined the Eastern Naval Command at Visakhapatnam. INS Venduruthy is an Indian Navy base located on Willingdon Island near Kochi, Kerala.  It serves as the Headquarters of the Southern Naval Command.  It is the largest training establishment of the Indian Navy.  INS Garuda is a naval air station located adjacent to INS Venduruthy.
