In a tweet, the DRDO said, “Very Short Range Air Defence System (VSHORADS) missile was successfully flight tested from a ground based portable launcher, off the coast of Odisha.”

The VSHORADS missiles were launched from a ground-based portable launcher at the Integrated Test Range (ITR) of the DRDO at Chandipur, off the coast of Odisha. The missile is a Man Portable Air Defence System (MANPAD) designed and developed indigenously by DRDO’s Research Centre Imarat (RCI), Hyderabad in collaboration with other DRDO facilities and various Indian industry partners.

A press statement from the Ministry of Defence said the design of the missile, including launcher, has been highly optimised to ensure easy portability. “Both the flight tests have completely met the mission objectives,” the release stated.

Officials said the air defence missile incorporates many novel technologies including miniaturised Reaction Control System (RCS) and integrated avionics, which have been successfully tested during the trials. The missile has been designed to neutralise low altitude aerial threats at short ranges and is propelled by a dual thrust solid motor.

The MoD said Defence Minister Rajnath Singh complimented and appreciated the efforts of the DRDO and industry partners and said this new missile equipped with modern technologies will give further technological boost to the Armed Forces. DRDO Chairman Dr Samir V Kamat congratulated the entire VSHORADS team on the successful tests.

The launch of the system was conducted against a high-speed aerial target mimicking an aircraft, which was successfully engaged. VL-SRSAM, jointly designed by three facilities of the DRDO for Indian Naval warships, is meant for neutralising various aerial threats at close ranges including sea-skimming targets.

“During the test launch, flight path and vehicle performance parameters were monitored using flight data, captured by various Range instruments such as Radar, Electro-optical tracking system (EOTS) and Telemetry systems deployed by ITR, Chandipur. The launch was monitored by senior scientists from various DRDO labs involved in the design and development of the system such as Defence Research & Development Laboratory (DRDL), Research Centre Imarat (RCI), Hyderabad and R&D Engineers, Pune,” said the Ministry of Defence in a statement.

The VL-SRSAM system has been designed to strike high-speed airborne targets at the range of 40 to 50 km and at an altitude of around 15 km. DRDO officials have said its design is based on the Astra missile, which is a Beyond Visual Range Air to Air missile.

Two key features of the VL-SRSAM are cruciform wings and thrust vectoring. The cruciform wings are four small wings arranged like a cross on four sides and give the projective a stable aerodynamic posture. The thrust vectoring is an ability to change the direction of the thrust from its engine control the angular velocity and the attitude of the missile, an official said.

VL-SRSAM is a canisterised system, which means it is stored and operated from specially designed compartments. In the canister, the inside environment is controlled thus making its transport and storage easier and improving the shelf life of weapons.

SFDR-based propulsion enables the missile to intercept aerial threats at very long ranges at supersonic speeds.

The performance of the system has been confirmed from the data captured by a number of Range instruments like Telemetry, Radar and Electro-Optical Tracking Systems (EOTS) deployed by ITR.

SFDR has been developed by Defence Research and Development Laboratory (DRDL), Hyderabad in collaboration with other DRDO laboratories such as RCI, Hyderabad and HEMRL, Pune.

Defence Minister Rajnath Singh congratulated DRDO for the successful trial of SFDR and said that this is an important milestone towards the development of critical missile technologies in the country.

QKD is primarily a mechanism to undertake secure communication which utilises a cryptographic protocol involving various components of quantum mechanics. The technology enables two communicating sides to come up with random secret keys shared by both of them and known exclusively to them, so only they can use it to encrypt and decrypt messages, thus achieving a very highly-secure communication.

In December 2020, the technology was tested for communication between two DRDO facilities in Hyderabad—the Defence Research and Development Laboratory (DRDL) and Research Centre Imarat (RCI)—over a distance of 12 km.

A press statement from the Ministry of Defence said on the latest test, “This technological breakthrough was achieved over a commercial-grade optical fibre already available in the field. With this success, the country has demonstrated indigenous technology of secure key transfer for bootstrapping military-grade communication security key hierarchy. The performance parameters have been measured and have been found to be repetitively within the reported international standards at sifted key rates of up to 10 kHz. This technology will enable security agencies to plan a suitable quantum communication network with indigenous technology backbone.”

Secure communications are vital for defence and strategic agencies across the globe and the distribution of encryption keys is the crucial factor for it. Sharing of keys over the air or wired links requires encryption, which in turn requires encryption keys to be pre-shared. Quantum-based communication offers a robust solution to sharing the keys securely. DRDO has undertaken multiple projects for the development of this technology.

The technology is expected to help define standards and formulate crypto technology-related policies that can use the QKD system in a unified Cipher Policy Committee (CPC) framework in the country for more secure “key management” for current and future military cryptographic systems.

In the last week of December 2020, DRDO Young Scientist Laboratory for Quantum Technologies (DYSL-QT), a DRDO facility based in Mumbai, developed a Quantum Random Number Generation (QRNG), which has the ability to detect random quantum events and convert those into a stream of binary digits. The QRNG system developed by DYSL-QT passed the global randomness testing standards of NIST and Die-harder Statistical Test Suites at the speed of around 150 kbps after post-processing. The generated random numbers were also evaluated and verified using DRDO’s indigenously developed Randomness Testing Statistical Test Suite of Scientific Analysis Group. With this development, India had entered the club of countries that have the technology to achieve the generation of random numbers based on the Quantum Phenomenon.

Most of the large economies and defence powers across the world have in the recent past formulated dedicated plans for the development of quantum technologies. These countries include the US, Canada, several European countries, China, Japan and South Korea. India has seen significant policy decisions and budget allocation for the sector.

However, senior DRDO scientists and defence officials say that developments in India need to be seen especially in the context of several claims made by China. China has said that it has achieved multiple breakthroughs in the quantum technology domain that included the world’s first quantum satellite, the world’s first optical quantum computing machine prototype and also a 2000 km long quantum communication link between Beijing and Shanghai.

DRDO had, in November, successfully tested the high-speed expendable aerial target (HEAT), ABHYAS, used for evaluation of various missile systems, from the Integrated Test Range (ITR), Chandipur.

The VL-SRSAM has been designed and developed jointly by three facilities of the DRDO. The key DRDO facilities that contributed to the development of the system are Defence Research and Development Laboratory (DRDL) and Research Centre Imarat (RCI), both from Hyderabad, and Research & Development Establishment (Engineers) based in Pune.

The missile has the capability of neutralising various aerial threats at close ranges including sea-skimming targets. The tactic of sea skimming is used by various anti-ship missiles and some fighter jets to avoid being detected by the radars onboard warships. For this, these assets fly as close as possible to sea surface and thus are difficult to detect and neutralise.

The missile has been designed to strike at the high-speed airborne targets at the range of 40 to 50 km and at an altitude of around 15 km. DRDO officials have said its design is based on Astra missile which is a Beyond Visual Range Air to Air missile. Two key features of the VL-SRSAM are cruciform wings and thrust vectoring. The cruciform wings are four small wings arranged like a cross on four sides and give the projective a stable aerodynamic posture.

The test on 7 December, was conducted from a vertical launcher against an electronic target at a very low altitude. “The flight path of the vehicle along with health parameters were monitored using a number of tracking instruments deployed by ITR, Chandipur. All sub-systems performed as per expectation.” said a press statement from the Ministry of DefenCe. In its maiden trial held on February 22, the DRDO had tested the weapon system twice.

The 7 December launch of the system was conducted to validate integrated operation of all weapon system components including the vertical launcher unit with controller, canisterised flight vehicle, weapon control system. .

A warship has to employ various defence mechanisms to protect itself from anti-ship missiles and adversary aircraft. One of the age-old methods is chaffs — which is a countermeasure technology used worldwide to protect naval ships from enemy’s radar and Radio Frequency (RF) missile seekers. Another method is deploying missiles to counter Anti Ship missiles. These systems have to have a swift detection mechanism, quick response, high speed and high manoeuvrability. The VL-SRSAM claims to have all these qualities. However, it will have to undergo tests in different conditions and configurations to be ready for deployment on board Indian Naval Ships.

It was a text book launch, which met all mission objectives. The telemetry and tracking systems installed at Interim Test Range (ITR), Balasore captured all the mission events.” While earlier tests have been conducted from Jaguar, this time HAL Hawk-1 was used, thus expanding the operating scope of weapons system.

The system belongs to the glide bomb category and its development began around 2012-13, with crucial inputs from the Indian Air Force and the first test was carried out in 2016.

The press statement said, “SAAW is indigenously designed and developed by DRDO’s Research Centre Imarat (RCI) Hyderabad. This is a 125-kilogram class smart weapon, capable of engaging ground enemy airfield assets such as radars, bunkers, taxi tracks, and runways, up to a range of 100 kilometres. The high precision guided bomb is lightweight compared to weapon system of the same class. The weapon was earlier successfully test fired from Jaguar aircraft.”
