Some of the known changes are as follows :- In accordance with naval traditions, the P-15B destroyers were christened after major Indian cities with historical and cultural connections, namely, Visakhapatnam, Mormugao, Imphal and Surat - representing the Indian states of Andhra Pradesh, Goa, Manipur and Gujarat.

[26] Additionally, the vessels of the class are equipped with one OTO Melara 76 mm naval gun manufactured by Bharat Heavy Electricals Limited at their Haridwar facility.

[3][31] The class also features two RBU-6000 (RPK-8) anti-submarine rocket launchers, capable of firing ASW projectiles to depths of up to 1,000 m (3,300 ft).

[32] As for the class' defensive abilities, each destroyer is equipped with two Kavach anti-missile decoy systems for neutralizing incoming aerial threats at short ranges.

[3] The EL/M-2248 is a multi-function, phased-array radar system featuring an azimuth of 360o, with the capability to track both aerial and surface targets - at a range of over 450 km (280 mi).

[33] The class further features the Thales LW 08 [de] (BEL RAWL-02) as its secondary radar suite.

[34] The LW-08 is a solid-state, two-dimensional, long-range D band surveillance radar, meant for providing target acquisition against aerial and surface threats.

[39] For electronic warfare (EW), the destroyers are equipped with the DRDL Shakti EW suite, designed to provide Indian warships an electronic layer of defence against modern radars and anti-ship missiles.

[41] Additionally, the suite is also equipped with an in-build radar fingerprinting and data recording replay feature for post-mission analysis and evaluation.

[44] No competitive bidding was conducted for the development of the vessels, since MDL was the only Indian shipyard at the time with the capability to build destroyers.

[48] In July 2019, a minor fire broke aboard the unfinished-Visakhapatnam, leaving one contract worker dead and another two injured.

[53][54] Completing its basin trials in early-December 2021, the destroyer proceeded on its maiden sea sortie on 19 December, coinciding with the 60th anniversary of Goa Liberation Day.

[63][64] The destroyer later took part in the 12th edition of the IN's "Presidential Fleet Review" on 21 February 2022, an event which was attended by Indian president Ram Nath Kovind and Indian naval chief R. Hari Kumar.
