DRDO’s Air Independent Propulsion System Gets Boost With Operation Of Land-Based Prototype

DRDO a step closer to boosting endurance of submarines.

Published

NEW DELHI: Air Independent Propulsion (AIP) has a force multiplier effect on the lethality of a diesel-electric submarine as it enhances the submerged endurance of the boat, several folds. Fuel cell-based AIP has merits in performance compared to other technologies.

The Defence Research and Development Organisation (DRDO) programme to build a fuel cell-based AIP system for Indian Naval Submarines has crossed several milestones in technology maturity.

Operation of the land-based prototype engineered to the form-and-fit of a submarine was witnessed by Chief of the Naval Staff Admiral Karambir Singh in the presence of Secretary, Department of Defence R&D and Chairman DRDO Dr G. Satheesh Reddy at the Naval Materials Research Laboratory in Ambernath, Maharashtra on Wednesday.


In his remarks, the Chief of the Naval Staff appreciated the breakthrough accomplishments achieved in this programme and said that the programme is of great value to the nation and Indian Navy in particular.

He urged DRDO and Indian Navy to continue the partnership to meet the timelines set for short and long-term goals.

The DRDO Chairman assured that all efforts will be made to meet the performance standards and timelines of the programme so that induction of DRDO AIP into operational Submarines could be achieved as per Indian Navy schedule.



Flag Officer Commanding-in-Chief(West), Chief of Material Indian Navy, Director General (Naval Systems & Materials), Director General (Armament & Combat Engineering Systems), Director (Naval Materials Research Laboratory) and Directors of participating laboratories were present on the occasion.

India Successfully Test-Fires Nuclear-Capable K-4 Ballistic Missile

K-4 is one of the two underwater missiles that are being developed by India for its submarine force.

VISHAKHAPATNAM (Andhra Pradesh): India has successfully test-fired a 3,500-kilometre range nuclear-capable missile that can be launched from a submarine. The test of the K-4 ballistic missile was conducted off the Vizag coast in Andhra Pradesh on Sunday.

With this test, India has moved one more step towards the induction of this ballistic missile on the INS Arihant class of nuclear submarines. The missile was developed by Defence Research and Development Organisation (DRDO).

Only the US, Russia and China have submarine-launched ballistic missiles of 3,500-kilometre range.


The three-metre-tall missile carries a nuclear warhead of over one tonne with a circular error probability far lower than that of Chinese ballistic missiles.

The K-4’s circular error of probability (the radius of the missile’s point of impact which is also a measure of the efficacy of its guidance systems) was 40 meters or less. This makes it ideal to strike targets from stand-off ranges.

The submarine-launched ballistic missile is the most important part of the air, land and sea nuclear triad and is at the front of India’s second-strike capability.



In November 2018, India had announced that its first nuclear-armed submarine Arihant had successfully completed its first deterrence patrol, heralding India’s entry into an exclusive club of powers with land, air and sea-based nuclear weapons delivery platforms.

Though dubbed the technology demonstrator, analysts had been of the view that the 6,000-tonne Arihant with a range of about 750km nevertheless sent a powerful signal to Pakistan and China that New Delhi’s underwater nuclear deterrence was “credible”, potent and functional.

Russia To Deliver S-400 Air Defence Systems To India By 2025

The S-400, an upgraded version of the S-300, had previously only been available to the Russian defence forces.

NEW DELHI: Russia said it has started production of S-400 long-range surface-to-air missile systems for India, and all five units will be delivered by 2025.

Russian Deputy Chief of Mission Roman Babushkin also said that a contract will be finalised shortly for joint production of Kamov lightweight multi-role military helicopters for India. He was addressing a joint press conference with Russian Ambassador Nikolai Kudashev in New Delhi yesterday.

Babushkin said that the Indian Armed forces will receive the first batch of 5,000 Kalashnikov rifles this year as well. These will be produced in India under a joint venture.


External Affairs Minister S Jaishankar will visit Russia on March 22 and March 23 to attend a meeting of the Russia-Indian-China trilateral, Kudashev said.

“Those having doubts over India’s approach on Kashmir can go there, we don’t have any doubt,” he said on not being invited to visit Jammu and Kashmir.

Asserting that the S-400 air defence missile systems are among best in the world, the diplomat said they will significantly bolster India’s air defence mechanism.



The S-400, an upgraded version of the S-300, had previously only been available to the Russian defence forces.

It is manufactured by Almaz-Antey and has been in service in Russia since 2007.

In October 2018, India signed a USD 5 billion deal to buy the air defence missile systems.

Rajnath Singh Dedicates 51st K9 Vajra-T Guns To Nation

The L&T officials showed the minister the different manoeuvres of the K-9 Vajra-T, a tracked self-propelled howitzer.

HAZIRA (Gujarat): Defence Minister Rajnath Singh today dedicated to the nation the 51st K9 Vajra self-propelled Howitzer gun made by L&T at Hazira in Gujarat.

Rajnath Singh put ‘tilak’ and drew the auspicious ‘Swastik’ symbol with kumkum on the new artillery. During the puja, he also offered flowers to the gun and broke a coconut.


L&T had in 2017 won the Rs 4,500-crore contract from the Ministry of Defence to supply 100 units of K9 Vajra-T 155 mm/52 calibre tracked self-propelled gun systems to the Indian Army under the Centre’s ‘Make in India’ initiative.

The K9 Vajra contract involves the delivery of 100 such systems in 42 months, which is the largest contract awarded to a private company by the Ministry of Defence.

The gun weighs 50 tonnes and can fire 47-kilogram bombs at targets up to a distance of 43 kilometres. It can also turn around at zero radius.

Speaking on this occasion at Hazira in Surat, Defence Minister Rajnath Singh has said that K9 Vajra-T guns dedicated to the nation today are indeed future-ready combat vehicles.



Singh said in his speech that he salutes the commitment and hard work of employees of L&T as the company’s Hazira complex is a sign of “new thinking of new India”.

“I see this complex has a new and astonishing achievement…There were many sectors in India where the private sector’s participation was almost nil.

Defence sector was one such example,” he said.

He said that L&T’s Armoured Systems Complex (ASC) has a state of art complex to manufacture and integrate advanced armoured platforms.

He said, these future-ready combat vehicles meet the requirement of 21st-century warfare including deep fire support to the longer firing range.


He said that under the Make in India programme, India will be not only a manufacturing hub, but also a net defence exporter.

J D Patil, senior executive vice-president for the company’s defence segment, as well as A M Naik, chairman of the company, were present at the event.

“L&T has always been at the forefront for all the national causes…We collaborate with the DRDO and the armed forces to understand their requirement,” Naik said in his speech.

K9 Vajra-T gun dedicated today has been delivered ahead of the schedule. L&T’s Armoured System Complex at Hazira in Surat had been dedicated to the nation by Prime Minister Narendra Modi in January Last year.

Last year, Prime Minister Narendra Modi shared a brief video of himself standing in a tank on his Twitter handle. “Checking out the tanks at L&T’s Armoured Systems Complex in Hazira,” Modi said in the tweet.

I congratulate the entire team of Larsen & Toubro for building the state-of-the-art K-9 Vajra Self Propelled Howitzer. This is a significant contribution towards India’s defence sector and protecting the country… Boosting ‘Make in India’ in the defence sector is our endeavour. I am glad that the private sector too is supporting this pursuit and making a valuable contribution,” the Prime Minister tweeted after the inauguration. He, however, did not address people at the inauguration.
