===Armament=== The weapons suite of the ships is designed to support its intended anti-submarine warfare operations in shallow waters. The anti-submarine weapons that equip the ship includes a forward-mounted RBU-6000, a triple 324 mm lightweight torpedo tube each on port and starboard equipped with Advanced Light-Weight Torpedo (ALWT) at the aft and anti-submarine mine-laying rails.

===Sensors===
As part of its sensor suite, the ships are equipped with Abhay compact active hull-mounted sonar (HMS), a towed low-frequency variable-depth sonar (LFVDS) procured from a joint venture firm between Indian CFF Fluid Control Ltd. and German Atlas Elektronik, a division of ThyssenKrupp Marine Systems (TKMS) along with an underwater acoustic communication system (UWACS).<ref name=":03" /><ref name=":15" />
The Abhay active sonar system — developed by DRDO's Naval Physical and Oceanographic Laboratory (NPOL) and manufactured by Bharat Electronics Limited (BEL) — includes transducer array, data acquisition system, power amplifier and the dual multi-function console (DMFC). The system utilises advanced adaptive signal and information processing techniques to detect, track and classify of targets.<ref name=":05">{{Cite web |last=Mitsopoulos|first=Dimitris|date=2025-06-25|title=India Commissions Its First ASW-SWC Corvette|url=https://www.navalnews.com/naval-news/2025/06/india-commissions-its-first-asw-swc-corvette/|access-date=2025-06-26|website=Naval News|language=en-US}}</ref> The compact system helps in the application of the systems onto smaller category of naval warships like Shallows Water Crafts, Light Frigates & Patrol Vessels by replacing legacy Russian sonar. Earlier, hull-mounted sonars were only limited to frigates and destroyers.<ref name=":03" />
Additionally, the ''Arnala''-class corvettes are equipped with two navigation radars, an electronic warfare suite which employs Radar Electronic Support Measures (R-ESM) and Communications ESM (C-ESM) or COMINT and is equipped for Satellite Communications (SATCOM). As part of its network-centric warfare suite, the entire sensors and weapon suite is integrated into the combat management system (CMS) and the ship is equipped with integrated bridge system (IBS), an expandable bathy theromograph (XBT), an automatic identification system (AIS), an echo sounder and an automatic weather observation system (AWOS). The ship employs an integrated ASW complex (IAC) which computes fire control solutions and facilitates firing of ASW weapons including torpedoes and rockets. The IAC was developed by BEL and DRDO.<ref name=":03" />
The ships are also equipped with Electronic Support Measures (ESM), Electronics Intelligence (ELINT) and a combat management system.<ref name=":15" />
===Capabilities=== Being vessels primed for anti-submarine warfare (ASW), the ASW-SWC vessels were conceived to undertake multiple missions, including "search-and-attack-unit" (SAU) roles, low-intensity maritime operations (LIMO), subsurface surveillance in littoral-waters and coordinated ASW operations with maritime-patrol aircraft (MPA).<ref name="naval-technology.com"/> In addition, the vessels also possess the capability subsurface surveillance and interdiction, within the vicinity coastal waters.<ref name="PIB-180625" /> The vessels can also be deployed for search-and-rescue (SAR) missions in littoral waters.<ref name="PIB-180625" /><ref>{{Cite web |title=Keels laid for Indian Navy's first ASWSWC and third large survey vessel |url=https://www.janes.com/defence-news/news-detail/keels-laid-for-indian-navys-first-aswswc-and-third-large-survey-vessel |website=Janes.com}}</ref> The corvettes are meant for operations within {{Convert|200|nmi|abbr=on}} of the coastline.<ref name="shephardmedia.com">{{Cite web|url=https://www.shephardmedia.com/news/naval-warfare/details-grses-small-anti-submarine-corvette-emerge/|title=Details of GRSE's small anti-submarine corvette emerge - Shephard Media|website=www.shephardmedia.com}}</ref>
