Indian Navy and MARCOS commandos rescued all 20 Iranian crew members from the hijacked vessel Azini off Somalia.
The 48-hour operation utilized non-kinetic tactics and aerial surveillance supported by an IAF C-17 aircraft.
The rescue successfully prevented Somali pirates from converting the fishing vessel into a mother ship for further regional attacks.
In a swift operation that lasted for over 48 hours, the Indian Navy has rescued a fishing vessel with 20 Iranian crew members off the coast of Somalia weeks after it was hijacked by pirates.
The vessel, Azini, was hijacked by an armed pirate group earlier last month, the Navy said on Tuesday.
The operation culminated in the safe rescue of all 20 crew members, with no casualties or injuries, it said.
The Iranian embassy in New Delhi expressed its "sincere appreciation" to the government of India, the Indian Navy and the Indian Air Force for the "successful operation" in rescuing the 20 Iranian crew members of the fishing vessel.
The Indian Navy said the hijacking represented a "significant maritime security threat", with the possibility of the vessel being employed as a "mother ship" to launch further attacks against merchant shipping in the region.
Responding to the situation, the Navy said, it tasked a mission-deployed warship to intervene, supported by a maritime reconnaissance aircraft.
"Working in close coordination, these platforms located the vessel after persistent surveillance, tracked its movements and employed calibrated non-kinetic measures to contain its movement and prevent its escape," it said in a statement.
It said marine commandos were deployed through a precision airdrop by an Indian Air Force (IAF) C-17 aircraft.
"Executing a swift and well-coordinated tactical intervention, the Indian Navy secured the vessel, overcame the pirate threat and ensured safe release of all 20 crew members," the Navy said.
It described the "successful operation" as a "testament" to the Indian Navy's high operational preparedness and ability to undertake complex maritime security operations through "seamless inter-service coordination".
"It also underscores India's unwavering commitment to remaining First Responder and Preferred Security Partner in the Indian Ocean Region," the Navy said.
"The Indian Navy stands committed to safeguarding seafarers, protecting vital maritime trade routes and ensuring a safe, secure and stable maritime environment in the Indian Ocean Region," it added.
In a social media post, the Iranian embassy said, "We highly commend the professionalism, courage and effective coordination demonstrated by the Indian armed forces, reflecting India's strong commitment to Humanitarian Assistance and Disaster Relief (HADR) and its role in saving lives beyond borders."
"This humanitarian operation stands as a testament to the spirit of friendship, solidarity and cooperation between Iran and India," it said.
"We extend our sincere gratitude to all those involved in ensuring the safe rescue of the Iranian crew," it added.
