Quantum key distribution demonstrated by the DRDO

To provide Quantum Communication between two laboratories of the DRDO, it has demonstrated a new technology which is a robust way to share encryption keys known as the Quantum Key Distribution. Using Fiber optics cable, encryptions keys are shared by means of Quantum Key Distribution (QKD). As bits are the smallest unit in classical computing, similarly the qubits are used as a basic resource in quantum computing.

It is a modern technology that informs the system if an unwanted element tries to sneak into the transmission. As soon as any foreign entity tries reading the code, the qubits get disturbed, it generates a transmission error that informs the end users.

It is a secure way to share encryption keys. Secure communications are significant as they provide safety to the confidential data related to defence and strategic agencies. Thus, time to time distribution of encryption keys is necessary.

Ministry of Defence headed by the defence minister Rajnath Singh congratulated the DRDO on this achievement. The two labs involved were The Defence Research & Development Laboratory (DRDL) and the Research Centre Imarat (RCI).




74% FDI in defence sector under automatic route

Nirmala Sitharaman leads Finance Ministry notified that the defense sector now will allow 74% Foreign Direct Investment (FDI) under the automatic route. In September 2020, the Commerce & Industry Ministry led by Mr. Piyush Goyal has raised the FDI limit to 74 % from 49%.

For this, an amendment was required in the Foreign Exchange Management Act (FEMA).

Global Share of Major Arms Import

In 2019, India was in the second rank in the list of biggest arms importers 2019, a report of Sweden based Stockholm International Research Institute suggests

(SIPRI). In the list of total military spending, India occupies rank 3. The United States of America and China are the only two countries ranking higher than us. As far as arms export is concerned the USA is the biggest exporter of military arms. It occupies 36% of the global trade. Top 25 companies of the world have done the business of $ 360 billion in 2019. As compared to the 2018 data, the percentage of increment is above 8.5%. On contrary, the United Nations Peacekeeping Operation Budget is much less.



India offering a trainer aircraft to the US Navy

US Navy is searching a trainer aircraft for its Under Graduate Jet Training System. India has responded with a LEAD in Fighter Trainer (LIFT) version of the Light Combat Aircraft (LCA) to the Request for Information (RFI). The manufacturer of the aircraft, Hindustan Aeronautics Limited (HAL), has successfully demonstrated deck based operations of the naval version of LCA. 

Requirements put forward by the US Navy in the RFP were that the aircraft should be capable of performing landing practice and touch and go events.

According to some official resources, the aircraft which is offered by the HAL is based on LCA Mk 1A ordered by the Indian Airforce. If the US Navy goes ahead, the next step will be done, that is the formal request for the proposal. The most positive element is that the LCA is one of the few aircraft which has demonstrated operations from an aircraft carrier.
