DRDO launches sonar systems test and evaluation facility for Indian Navy (nov.08)

India’s Defence Research and Development Organisation (DRDO) has launched a new testing and evaluation facility for sonar systems of the Indian Navy.
Announced by the Indian Ministry of Defence (MoD), the new facility is now operational at DRDO’s Naval Physical and Oceanographic Laboratory (NPOL) in Kochi, Kerala, India.
This newly launched facility is named as Hull Module of Submersible Platform for Acoustic Characterisation and Evaluation (SPACE).
The design of this facility is based on the concept, design and requirements proposed by the NPOL.

The SPACE facility will primarily test and assess sonar systems aboard different types of naval vessels, such as submarines, warships and maritime aircraft or helicopters.
The centre will also allow rapid deployment and easy recovery of other scientific packages, including transducers and sensors.
The new ‘one-of-a-kind’ facility is a submersible platform that can reach up to the depths of around 100m.
In a statement, Indian MoD said: “The uniqueness of this facility lies in the specially designed submersible platform, which can be lowered up to depths of 100m using a series of synchronously operated winches.”

The SPACE facility has been constructed by the Indian company Larsen & Toubro (L&T) Shipbuilding in Chennai.
According to the MoD, the design and construction of the SPACE facility complies to all the statutory needs and requirements of the Indian Register of Shipping.
Furthermore, the platform also adheres to the needs of the vessel classifying authority as well as the inspection and registration criteria set by the Kerala Inland Vessel Rules.
This new facility has further boosted the Government of India’s ‘AatmaNirbhar Bharat’ and ‘Make in India’ initiatives.
Earlier this year, the MoD contracted L&T to build two multi-purpose vessels for the service.

Indian Ocean Rim Association (IORA) Seminar On Illegal Unreported And Unregulated (IUU) Fishing​

A Seminar on Illegal, Unreported and Unregulated (IUU) Fishing, under the aegis of Indian Ocean Rim Association (IORA), was conducted by the Indian Navy at Goa on 02 November 2022.​


As the third largest ocean, the Indian Ocean Region (IOR) is a lifeline for nearly 35% of global population. Fish and Fisheries comprise important components of food security chain. These also contribute significantly to national socio-economic development. Sustainable fishing is seriously compromised by IUU fishing activities and are therefore a major cause of concern for the littorals of IOR. This was accordingly identified as an area of greater collaboration by the IORA Working Group on Maritime Safety and Security (WGMSS), established in September 2018. The WGMSS is presently chaired by Sri Lanka, and is advancing the IORA Action Plan 2017-2021, adopted by IORA Member States.

The Seminar was conducted by the Indian Navy on behalf of the Ministry of Defence, under the guidance of the Ministry of External Affairs and duly supported by the Department of Fisheries, functioning under the Ministry of Fisheries, Animal Husbandry and Dairying and other agencies of the Govt of India.

Representatives from 14 out of 23 IORA Member States (Bangladesh, Comoros, France, India, Indonesia, Kenya, Madagascar, Maldives, Mauritius, Malaysia, Sri Lanka, Seychelles, Tanzania and Thailand) attended the Seminar.

During the Seminar, the attendees reviewed the scale of IUU fishing activities in the IOR, discussed the adverse effects of such developments on marine ecosystem, the legal voids in tackling these activities and deliberated upon collaborative strategies and capacity building measures that could be pursued by the IORA Member States towards mitigating the menace of IUU Fishing in IOR.

Established in 1997, this year marks the 25th Anniversary of IORA. India, as a founding member of IORA, remains committed to IORA’s agenda of promoting cooperation in the region to ensure a peaceful, stable and prosperous Indian Ocean Region.
 
Programme SAMUDRIKA aims at the design and indigenous development of a family of Seven Electronic Warfare Systems meeting the requirements of Navy for different platforms viz., Ships, Helicopters and Aircrafts, with a firm commitment from Navy for quantity production and induction of these Systems. Seven EW/ESM systems are grouped under two projects namely Ship-Borne projects & Air-Borne Projects. Ship-borne systems are SHAKTI, NAYAN and TUSHAR. Air-Borne systems are SARANG, SARAKSHI, SARVADHARI and NIKASH.Order has been placed by Indian Navy for 12 Nos. of Shakti and 07 Nos. of Nayan systems.
