The final assembly of sonobuoys from the U.S., meant for detecting submarines underwater, will be done in India and an operational production line is expected to be ready in 2027, according to the U.S. company Ultra Maritime (UM). The systems will be co-produced in India in partnership with defence public sector undertaking Bharat Dynamics Limited (BDL).
In a significant development, India and the U.S. last week announced the “first-of-its-kind partnership on co-production” of U.S. sonobuoys for Undersea Domain Awareness for the Indian Navy, a high-end technology that allows tracking of submarines in the deep seas and oceans. The announcement was made in the fact sheet issued at the end of U.S. National Security Advisor Jake Sullivan’s visit to India last week.
“Workshare will be in line with the principles of Make in India. Final assembly will be done in India. Our goal is to have an operational production line in 2027,” Ultra Maritime said in response to questions from The Hindu sent on email. “These will be U.S.-specification sonobuoys equivalent to those used on the P-8 aircraft.”
Chairman of BDL, Commodore A. Madhavarao (retd.), had stated that they are looking to set up joint production with Ultra Maritime in Vishakhapatnam.
The U.S.-based company, a world-leader in the design and production of undersea warfare capabilities, has already stated that in line with the U.S.-India Initiative on Critical and Emerging Technologies (ICET) launched in May 2022, they will also pursue new sonobuoy technologies with BDL teams to optimise their acoustic performance in the unique environment of the Indian Ocean, enabling wide area search through bespoke multi-static active solutions. To a question, the company clarified that this was in addition to the initial production already envisaged.
On the future outlook, Ultra Maritime said it was working with BDL to identify opportunities for Indian suppliers to enter its global supply chain.
An Ultra Maritime statement issued last week had stated that the UM sonobuoys co-produced in India are interchangeable and interoperable between the U.S. Navy, Indian Navy and allied P-8, MH-60R and the MQ-9B Sea Guardian aircraft.
The development is of particular significance as India has over the years acquired a series of military platforms from the U.S. that are also operated by other countries in the region, especially Australia and Japan, which too are part of the Quad grouping and also hold the Malabar naval exercise. These sonobuoys are dropped from aircraft and helicopters. India is also pursuing another technology – sensors embedded on the ocean bed – and recently some progress has been made as a few Indian start-ups showcased the technology that is now undergoing trials.
As China undertakes massive expansion of its navy and also its presence in the Indian Ocean, undersea domain awareness has become critical and Indian Navy has been collaborating with countries on the region, especially the Quad group.
Indian Navy operates the P-8I long-range maritime patrol aircraft, is inducting the MH-60R multi-role helicopters and has two MQ-9A armed High Altitude Long Endurance (HALE) Remotely Piloted Aircraft Systems on lease. It signed a $3.5 billion contract in October 2024 for 31 MQ-9B–15 Sea Guardians for the Indian Navy and 16 Sky Guardians, eight each for the Army and Air Force, with deliveries to begin from January 2029.
