'''''Arnala'' class''' was an Indian designation for the [[Petya-class frigate|Petya III-class]] vessels of the [[Indian Navy]].<ref name=gs-arnala>{{cite web|url=http://www.globalsecurity.org/military/world/india/p-arnala.htm|title=P68 Arnala Class|publisher=GlobalSecurity.org|access-date=2012-05-16}}</ref>

Although these vessels were classified as frigates in the [[Soviet Navy]], they were classified by the Indian Navy as anti-submarine [[corvettes]] due to their role and smaller size. Vessels of the class were named for Indian islands.

==Operational history==
{{ship|INS|Kiltan|P79}} and {{ship|INS|Katchall|P81}} were part of the task force for [[Operation Trident (1971)|Operation Trident]] during the [[Indo-Pakistan War of 1971]].<ref name=br-trident>{{Cite web|url=http://www.bharat-rakshak.com/NAVY/History/1971War/44-Attacks-On-Karachi.html |title=Trident, Grandslam and Python: Attacks on Karachi |url-status=dead |archive-url=https://web.archive.org/web/20090926174134/http://www.bharat-rakshak.com/NAVY/History/1971War/44-Attacks-On-Karachi.html |archive-date=26 September 2009 }}</ref><ref name=hiranandani-triumph>{{cite book|url=https://books.google.com/books?id=zFyMKROi46kC&q=venus%20challenger&pg=PA187|title=Transition to Triumph: History of the Indian Navy, 1965-1975|author=Gulab Mohanlal Hiranandani|author-link=Gulab Mohanlal Hiranandani|page=187|publisher=Lancer Publishers & Distributors|access-date=2012-05-16|isbn=9781897829721|year=2000}}</ref>

The hulls of this class were of relatively inferior quality built only 5mm thick for use in the [[Baltic Sea|Baltic sea]] and [[Black Sea|Black seas]], compared to the rest of the Navy's mostly [[United Kingdom|British]] built ships which had 8mm thick hulls requiring the vessels to undergo major refit every 5 years to prevent [[corrosion]]. The Indian Navy constructed the Naval Dockyard at [[Visakhapatnam]], primarily to service [[Russia]]n vessels. But given the lack of engineering support from Russia there were inordinate delays in completing the servicing facility. This resulted in considerable delay of the second refit for {{ship|INS|Andaman|P74}}, which was in poor repair and subsequently was lost at sea in conditions, {{convert|140|mi|km}} east of [[Visakhapatnam]] on 21 August 1990 around 2:03 pm, where it was conducting anti-submarine exercises with five other Indian warships. The Andaman's loss cost the navy an estimated Rs 8 crore, including the initial cost of the ship and weapons on board, as well as the lives of 15 sailors.<ref name=in-andaman>{{cite book|url=http://indiannavy.nic.in/t2t2e/trans2emins/29_foundering_andaman.htm|title=Transition to Eminence: The Indian Navy 1976-1990|author=Gulab Mohanlal Hiranandani|page=243|publisher=Lancer Publishers & Distributors|access-date=2012-05-16}}</ref><ref>{{Cite web |title=Loss of INS Andaman points to maintenance problems in Indian Navy |url=https://www.indiatoday.in/magazine/defence/story/19900930-loss-of-ins-andaman-points-to-maintenance-problems-in-indian-navy-813061-1990-09-29 |access-date=2024-02-07 |website=India Today |language=en}}</ref>

==Vessels==
The corvettes of this class constituted the 31st Patrol Vessel Squadron of the Eastern Naval Command and the 32nd Patrol Vessel Squadron of the Western Naval Command.<ref name=br-petya>{{cite web|url=http://www.bharatrakshak.com/NAVY/Ships/Past/5-Petya-II.html |archive-url=https://web.archive.org/web/20110707231549/http://www.bharatrakshak.com/NAVY/Ships/Past/5-Petya-II.html |url-status=dead |archive-date=2011-07-07 |title=Petya II Class |publisher=Bharat Rakshak |access-date=2012-05-16 }}</ref>
