The Foxtrot class was the NATO reporting name of a class of diesel-electric patrol submarines that were built in the Soviet Union. The Soviet designation of this class was Project 641. The Foxtrot class was designed to replace the earlier Zulu class, which suffered from structural weaknesses and harmonic vibration problems that limited its operational depth and submerged speed. The first Foxtrot keel was laid down in 1957 and commissioned in 1958 and the last was completed in 1983. A total of 58 were built for the Soviet Navy at the Sudomekh division of the Admiralty Shipyard, Saint Petersburg. Additional hulls were built for other countries.
The Scorpène-class submarines are a class of diesel-electric attack submarines jointly developed by the French Naval Group and the Spanish company Navantia. It features diesel propulsion and an additional air-independent propulsion (AIP). It is now marketed as the Scorpène 2000.
INS Ranjit is the third of the five Rajput-class destroyer built for the Indian Navy. Ranjit was commissioned on 15 September 1983 and remained in service till 6 May 2019, when it was decommissioned.
The Pondicherry class are a class of minesweepers built for the Indian Navy by the Soviet Union. They are modified versions of the Natya-class minesweeper. The vessels were acquired in two batches. The first were purchased from 1977 to 1980 and the second from 1986 to 1988. Technically, the second batch is referred to as the Karwar class but are physically identical to the first batch with the exception of additional surface-to-air missiles. As minesweepers, they are large and heavily armed. They can serve a dual purpose as an anti-submarine warfare escort. Their hulls are constructed of U3 low magnetic signature steel.

The Kamorta-class corvettes or Project 28 are a class of anti-submarine warfare stealth corvettes currently in service with the Indian Navy. Built at Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, they are the first anti-submarine warfare stealth corvettes to be built in India. Project 28 was approved in 2003, with construction of the lead ship, INS Kamorta commencing on 12 August 2005. All of the four corvettes, INS Kamorta, INS Kadmatt, INS Kiltan and INS Kavaratti were commissioned in 2014, 2016, 2017 and 2020 respectively.
