According to an Indian MoD statement:
The Mazagon Dock Shipbuilders Limited has played a pivotal role in contributing to our nation’s maritime capabilities. MDL has consistently demonstrated expertise and technological prowess, in the construction of warships and delivering vessels ranging from patrol boats to stealth frigates. MDL’s contributions have not only enhanced country’s defence capabilities but has also played a significant role in bolstering indigenous manufacture and self-reliance. Following the launch, ‘Mahendragiri’ will join its three sister ships at the Wet Basins of MDL, to progress remaining outfitting activities and equipment trials, in the run up to their delivery and commissioning.
Mahendragiri is the fourth and final Project 17A frigate built by MDL. For the record, the first-in-class ship, Nilgiri , was launched in September 2019 by MDL. The first Project 17A frigate built by GRSE, Himgiri, was launched in December 2020. Seven vessels of the class are planned. Four are being built by MDL and three by GRSE.
