With this delivery, the Indian Navy has received six Project 17A frigates in less than 17 months, following the initial delivery of INS Nilgiri by MDSL on 20 December 2024.
“The delivery marks a significant milestone in achieving ‘self-reliance in warship design and construction,” the Indian Ministry of Defence (MoD) said in a statement 1 MAY 2026.
The Project 17A programme includes a total of seven ships, four built by MDSL and three by Garden Reach Shipbuilders & Engineers (GRSE).
The series features vessels named after Indian hill ranges, including INS Nilgiri, INS Himgiri, INS Udaygiri, INS Dunagiri, INS Taragiri, INS Vindhyagiri, and INS Mahendragiri.
INS Vindhyagiri, the sixth ship in the series and constructed by GRSE, was launched in 2023 and is awaiting delivery to the Indian Navy.
The fourth ship under the programme, INS Taragiri, was commissioned last month.
The Project 17A vessels are designed by the Warship Design Bureau, while the Warship Overseeing Team in Mumbai managed construction oversight.
The Mahendragiri and its sister ships follow the Shivalik-class, introducing advanced stealth features, updated weapons and sensor suites, as well as platform management improvements.
The ships operate with Combined Diesel or Gas (CODOG) propulsion, utilising both diesel engines and gas turbines to drive controllable pitch propellers, managed by an Integrated Platform Management System.
According to MoD, Project 17A frigates are equipped for anti-surface, anti-air, and anti-submarine operations, and each ship is designed to meet varying operational demands in maritime security.
Production of these frigates recorded 75% indigenous content, involving more than 200 micro, small, and medium enterprises (MSMEs).
It also generated direct employment for about 4,000 people, with more than 10,000 individuals engaged indirectly, the Ministry said.
