The ship successfully completed Sea Trials and Final Machinery Trials within two months of Basin Trials. MDL has delivered five warships and one submarine to the Indian Navy in the last sixteen months, with key combat systems achieving full operational readiness prior to delivery.
The commissioning of INS Mahendragiri underscores MDL's commitment to the Atmanirbhar Bharat Abhiyan and Make in India initiatives, with approximately 75% indigenous content.
