New Delhi: India today said it has successfully tested a 5.56x30mm protective carbine designed by its defence research agency, clearing its way for induction into the armed forces.
The Defence Research and Development Organisation (DRDO) had designed the Joint Venture Protective Carbine (JVPC) and the latest tests were the final phase of user trials, the final leg carried out in extreme temperature conditions in the summer and high altitudes in the winter.
“(The) JVPC has successfully met the stringent performance criteria of reliability and accuracy in addition to quality trials conducted by DGQA (Directorate General of Qualitative Assurance),” a Ministry of Defence statement said.
The JVPC is a gas-operated semi bull-pup automatic weapon having more than 700 rpm rate of fire. The effective range of the carbine is more than 100 metres and weighs about three kg with key features like high reliability, low recoil, retractable butt, ergonomic design, single hand firing capability, and multiple Picatinny rails.
“These features make it a very potent weapon for counter-insurgency and counter-terrorism operations by (the) security agencies.”
The carbine has been designed, according to Indian Army‘s General Staff Qualitative Requirements (GSQR), by Armament Research and Development Establishment (ARDE), a Pune-based laboratory of DRDO. The weapon is manufactured at Ordnance Factory Board‘s Small Arms Factory at Kanpur, while the ammunition is manufactured at Ammunition Factory at Khadki in Pune.
“The weapon has already passed the MHA (Ministry of Home Affairs) trials and procurement action is initiated by the CAPFs (Central Armed Police Forces) and various state police organisations,” the statement said.
DRDO Chairman and Department of Defence Research and Development Secretary Dr G. Satheesh Reddy congratulated the defence scientists, user team, and all the public and private agencies involved in manufacturing the JVPC for the milestone.
DRDO tests Quantum Communications
On Dec. 9, DRDO achieved a milestone when two of its laboratories carried out a successful trials for Quantum Key Distribution (QKD) technology to test a secure communication system.
“Secure communications are vital for defence and strategic agencies the world over and distribution of encryption keys from time to time is an important requirement in this context,” a defence ministry statement said.
“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.”
The DRDO undertook the project for development of this technology. Rajnath Singh congratulated the DRDO team for successful demonstration of QKD communication.
The DRDO’s Bengaluru-based Centre for Artificial Intelligence and Robotics (CAIR) and the Mumbai-based DRDO Young Scientists Laboratory for Quantum Technologies (DYSL-QT) developed the technology.
“Quantum Communication using time-bin Quantum Key Distribution scheme was performed under realistic conditions. The setup also demonstrated the validation of detection of a third party trying to gain knowledge of the communication,” the statement said.
“Quantum-based security against eavesdropping was validated for the deployed system at over 12kms range and 10dB attenuation over fibre optic channel.”
Continuous wave laser source was used to generate photons without depolarisation effect. The timing accuracy employed in the set up was of the order of picoseconds.
The Single Photon Avalanche Detector (SPAD) recorded arrival of photons and key rate was achieved in the range of kbps with low Quantum bit error rate.
Software was developed for data acquisition, time synchronisation, post-processing, determining Quantum bit error rate and extracting other important parameters.
“The work being done at DRDO will be used to enable Start-ups and Small and Medium Enterprises (SMEs) in the domain of Quantum information technologies.
“It will also serve to define standards and crypto policies that can leverage QKD system in a unified Cipher Policy Committee (CPC) framework for more secure and pragmatic key management for current and future military cryptographic systems.”
