Defence Secretary Inaugurates Hindi Library ‘GYANDEEP’
Defence Secretary Shri Rajesh Kumar Singh inaugurated GYANDEEP, a newly established Hindi library at Sena Bhawan in New Delhi, on 22 October 2026. The initiative was launched as part of the Ministry of Defence’s Special Campaign 6, which is being conducted from 2 to 31 October 2026.
Promoting Hindi in Official Work
GYANDEEP has been established to encourage reading Hindi books and literature, increase the use of Hindi in official communication and strengthen the culture of working in Hindi within the Ministry of Defence.
The initiative supports the effective implementation of the government’s Rajbhasha policy and aims to promote excellence in the use of Hindi in administrative activities.
Achievements Under Special Campaign 6
The campaign has also focused on improving workplace efficiency, reducing unnecessary paperwork and making better use of government office space.
Important achievements reported under the campaign include:
- Approximately 35,000 square feet of space was cleared in South Block and handed over to the Project Yuga Yugeen Bharat Museum (YYBM).
- 1,361 e-files were closed.
- 1,746 physical files were weeded out.
- Disposal of electronic waste and other obsolete items generated revenue of ₹4.22 lakh.
These measures aim to improve record management, free up office space and encourage cleaner, more efficient government workplaces.
Recognition of Swachhta Veers
During the inauguration, the Defence Secretary felicitated eight Swachhta Veers for their notable contributions to the ongoing campaign. Their recognition highlights the role of employees in maintaining cleanliness, improving office management and supporting administrative reforms.
Significance
The establishment of GYANDEEP combines the promotion of Hindi literature with broader administrative improvement initiatives. The campaign’s achievements also demonstrate the importance of digitisation, systematic disposal of outdated records and efficient utilisation of public resources.

Ministry of Defence Floats Tender for 500 Scramjet Propulsion Systems
The Ministry of Defence has reportedly issued a tender for 500 scramjet propulsion systems intended to support India’s hypersonic missile programme. The proposed procurement reflects the growing importance of advanced propulsion technologies in strengthening the country’s indigenous defence capabilities.
The tender information cited in the supplied material is listed under Tender Information IA: 011-23018861.
What Is Scramjet Technology?
A scramjet, or supersonic combustion ramjet, is an air-breathing propulsion system designed to operate at extremely high speeds. Unlike conventional rocket engines, which generally carry both fuel and an oxidiser, a scramjet uses oxygen from the surrounding atmosphere during flight.
This technology is particularly relevant to hypersonic flight, generally defined as speeds exceeding Mach 5, or five times the speed of sound.
Importance for Hypersonic Missiles
Scramjet propulsion is considered a key technology for next-generation hypersonic cruise missiles. Its ability to use atmospheric oxygen can reduce the need to carry an onboard oxidiser, potentially supporting sustained high-speed flight under suitable operating conditions.
The proposed procurement is expected to support efforts to develop India’s hypersonic weapons ecosystem and strengthen long-range precision-strike capabilities. Such systems could contribute to defence modernisation, strategic deterrence and operational effectiveness.
Progress in Indigenous Development
The tender follows advances in India’s domestic hypersonic propulsion research. The supplied material refers to successful long-duration scramjet combustor testing conducted by the Defence Research and Development Organisation (DRDO).
Such tests are important because stable combustion at hypersonic speeds presents substantial engineering challenges. Progress in this field can help build the technological foundation required for future hypersonic missile systems.
Strategic Significance
Developing advanced propulsion systems domestically could help India strengthen its defence technology base and reduce dependence on external sources for critical components. However, a tender by itself does not confirm that all 500 systems have been contracted, manufactured or inducted into service.
Key Facts for Defence Exams
- Procuring ministry: Ministry of Defence
- Proposed quantity: 500 scramjet propulsion systems
- Intended application: India’s hypersonic missile programme
- Technology: Supersonic combustion ramjet
- Hypersonic speed benchmark: Above Mach 5
- Organisation mentioned in connection with propulsion research: DRDO
- Tender reference in supplied material: IA: 011-23018861
Indian Navy Conducts Rafale Marine Trials in Goa
The Indian Navy is conducting trials of the Rafale Marine (Rafale-M) fighter aircraft in Goa to assess the modifications required for operating the aircraft from India’s aircraft carrier, INS Vikrant. These trials are an important step towards integrating a modern carrier-based fighter into the Navy’s aviation capabilities.
What Is the Rafale Marine?
The Rafale-M is a naval version of the Rafale multirole fighter developed by France’s Dassault Aviation. Designed for carrier operations, the aircraft is already in service with the French Navy.
Its design enables it to perform a variety of missions, including air defence, maritime strike, reconnaissance and attacks against targets on land.
India–France Rafale-Marine Agreement
On 28 April 2025, India signed an agreement with France to acquire 26 Rafale-Marine fighter aircraft for approximately ₹63,000 crore, according to the supplied material.
The planned fleet comprises:
- 22 single-seat aircraft
- 4 twin-seat aircraft
The agreement also covers pilot training, flight simulators, weapons, essential equipment and long-term maintenance support. It includes a transfer-of-technology provision for integrating indigenous weapons in India, consistent with the broader Aatmanirbhar Bharat initiative.
The deal also provides additional equipment for Rafale aircraft already operated by the Indian Air Force.
Why Are Trials Being Conducted?
Carrier-based aircraft must meet specific requirements for take-off, landing and operation in the demanding maritime environment. Trials in Goa are intended to evaluate the modifications needed to make the Rafale-M suitable for operations from INS Vikrant.
INS Vikrant employs the STOBAR system, meaning Short Take-Off But Arrested Recovery. Aircraft take off using a ski-jump ramp and land with the assistance of arrestor wires. Compatibility with these arrangements is a key consideration when preparing a fighter for carrier service.
Enhancing India’s Naval Air Power
The Indian Navy operates two aircraft carriers: INS Vikrant and INS Vikramaditya. The acquisition of Rafale-M aircraft is intended to strengthen the Navy’s carrier-based combat capabilities.
The aircraft are expected to support air defence, maritime strike, reconnaissance and land-attack missions. Their multirole capability can help protect naval formations, engage hostile aircraft and improve the Navy’s ability to operate across contested maritime areas.
The aircraft’s eventual induction will depend on the completion of the necessary testing, integration and delivery process.

COAS Flight Safety Trophy Presented to Army Aviation Squadrons
Introduction
Chief of Army Staff (COAS) General Dhiraj Seth presented the COAS Flight Safety Trophy to two Army Aviation squadrons during the Army Commanders’ Conference 2026. The awards recognise the importance of safe flying practices, operational discipline and professional excellence in Army aviation.
Award Winners
The trophies were presented in two categories:
- Single-Engine Category: 665 Army Aviation Squadron (R&O)
- Twin-Engine Category: 209 Army Aviation Squadron (UH)
The recognition acknowledges the squadrons’ performance in maintaining flight-safety standards within their respective categories.
Importance of Flight Safety in Army Aviation
Army Aviation supports a range of operational activities, including troop movement, reconnaissance, logistics and other missions requiring aerial support. These operations can involve challenging terrain, demanding weather conditions and complex mission requirements.
Maintaining flight safety therefore requires rigorous training, disciplined procedures, sound operational decisions and consistent adherence to established aviation standards.
Significance of the Awards
The COAS Flight Safety Trophy encourages a strong safety culture across Army Aviation units. Recognising high standards of performance reinforces the principle that operational readiness must go hand in hand with professional responsibility and risk management.
The awards also highlight the Indian Army’s emphasis on improving aviation effectiveness while protecting personnel and equipment.
