The sonar can work in both active and passive mode, and is capable of interception and underwater communication. It can detect both surface ships and submarines at a range of a few kilometres. The team developing the sonar was awarded the Agni Award for self-reliance by the Indian Prime Minister in May 2007.
Can India make nuclear submarines?
India, which already operates nuclear ballistic missile submarines, plans to build its own SSN, which has already got government clearance. India has more experience in making submarines than Australia, having built the conventional Shishumar and Scorpene classes, and nuclear Arihant class.
Can India make its own submarine?
They were developed under the ₹90,000 crore (US$12 billion) Advanced Technology Vessel (ATV) project to design and build nuclear-powered submarines. These vessels are classified as ‘strategic strike nuclear submarines’ by India….Arihant-class submarine.

What is the full form of sonar?
Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves. There are two types of sonar—active and passive.
Who gave India nuclear submarine?
The Soviets provided India eight ‘Foxtrot’-class conventional submarines, and top officials spoke of eventually providing a fleet of nuclear-powered submarines.
Is India making nuclear weapons?
India has developed and possesses weapons of mass destruction in the form of nuclear weapons. In 1999, India was estimated to have 800 kg of separated reactor-grade plutonium, with a total amount of 8,300 kg of civilian plutonium, enough for approximately 1,000 nuclear weapons.
How was sonar used in ww1?
During WWI, submarines were detected by listening for their engines or propellers. A simple two-earphone (air tube) device was worn by the sonar operator who could determine the direction from which the sound arrived by mechanically rotating the receiver.
When was the sonar invented?
The first recorded use of the technique was by Leonardo da Vinci in 1490 who used a tube inserted into the water to detect vessels by ear. It was developed during World War I to counter the growing threat of submarine warfare, with an operational passive sonar system in use by 1918.
Who discovered sonar?
Lewis Nixon invented the very first Sonar type listening device in 1906 as a way of detecting icebergs. Interest in Sonar increased during World War I when there was a need to be able to detect submarines.
“The Navy needed a new, lighter-weight Variable Depth Sonar system that also met increased detection range and maximum tow speed and depth requirements,” said Joe Monti, a Raytheon Technologies surface ship anti-submarine warfare program director.
What is the US Navy’s new anti-submarine surveillance system?
The U.S. Navy is in process of developing a new, more rapidly deployable, fixed, persistent, deep water active anti-submarine surveillance system. This system would consist of large sonar arrays attached to buoys that ships could emplace in a particular spot in the ocean straight from inside a standard shipping container.
What missiles does India use in P-8I?
India has purchased AGM-84L Harpoon Block II missiles and Mk 54 All-Up-Round Lightweight torpedoes for the P-8I. In July 2012, Boeing began flight testing of the P-8I. On 19 December 2012, the first P-8I was handed over at Boeing’s facility in Seattle; it was inducted into the Indian Navy on 15 May 2013.
The Indian Navy inducted the first squadron in November 2015. P-8Is participated in the 2017 Doklam Standoff between Indian Army and China’s People’s Liberation Army. The Indian Navy also used the P-8I to monitor the Pakistani Army during the 2019 Pulwama standoff.
