What happened:
On December 19, 2025, INS Sindhughosh, the lead submarine of her class, was decommissioned at sunset at the Naval Dockyard in Mumbai. The ceremony was held in the presence of Vice Admiral Krishna Swaminathan, Flag Officer Commanding-in-Chief, Western Naval Command. The submarine was paid off under the command of Lt Cdr Rajat Sharma, with Capt KR Ajrekar (retd) as the guest of honour.
Why it matters to India:
The decommissioning marks the end of four decades of operational service by a key conventional submarine, reflecting the Indian Navy’s transition towards newer, more advanced undersea platforms while honouring legacy assets that strengthened maritime security.
