INS Sindhughosh Decommissioned After Four Decades of Naval Service

Decommissioning of a Naval Stalwart

INS Sindhughosh Decommissioned After Four Decades of Naval Service: INS Sindhughosh, the lead submarine of her class, was formally decommissioned after completing 40 years of operational service in the Indian Navy. The ceremony marked the conclusion of one of the longest-serving conventional submarines in India’s maritime history.

The decommissioning took place at Naval Dockyard Mumbai, a key maintenance and operational hub for India’s western seaboard. The submarine was officially paid off at sunset on December 19, 2025, symbolising the end of active duty.

Ceremony and Command Presence

The ceremony was conducted under the authority of Vice Admiral Krishna Swaminathan, the Flag Officer Commanding-in-Chief of the Western Naval Command. His presence highlighted the operational importance of the submarine within the western maritime theatre.

Lieutenant Commander Rajat Sharma, the last Commanding Officer of INS Sindhughosh, oversaw the paying-off process. The event followed established naval traditions that honour both the platform and its crew.

Legacy and Veteran Participation

The ceremony witnessed participation from several distinguished naval veterans and officers. Captain K R Ajrekar (Retd.), the second Commanding Officer of INS Sindhughosh, attended as the Guest of Honour.

Former Chief of Naval Staff Admiral V S Shekhawat (Retd.), along with past commanding officers and members of the commissioning crew, were also present. Their attendance reflected the submarine’s enduring legacy across generations of naval leadership.

Operational Contribution of INS Sindhughosh

Commissioned in the mid-1980s, INS Sindhughosh entered service during a critical phase of expansion and modernisation of India’s submarine arm. As the lead vessel of her class, she set operational standards for subsequent submarines.

The submarine played a vital role in underwater patrols, training missions, and deterrence operations across India’s maritime zones. Her service strengthened India’s ability to safeguard sea lines of communication and maintain strategic balance in the Indian Ocean region.

Static GK fact: Conventional submarines are diesel-electric powered platforms primarily used for coastal defence, surveillance, and sea denial missions.

Strategic Significance of Decommissioning

The decommissioning of INS Sindhughosh reflects the natural life-cycle progression of naval assets. Submarines typically serve for several decades, after which maintenance demands and technological limitations necessitate withdrawal.

Such decommissioning decisions are also aligned with fleet rationalisation and resource optimisation. Older platforms are phased out to ensure safety, efficiency, and combat effectiveness.

Transition in India’s Submarine Fleet

The retirement of INS Sindhughosh comes amid a broader transition within India’s submarine fleet. The Indian Navy is progressively shifting towards modern underwater platforms with enhanced stealth, endurance, and combat systems.

Simultaneously, the Navy continues to focus on life-cycle management, refits, and operational readiness of existing submarines. This balanced approach ensures continuity of deterrence while integrating advanced capabilities.

Static GK Tip: The Western Naval Command, headquartered in Mumbai, is responsible for safeguarding India’s western maritime frontier.
