CDS 2 2026 Defence Current Affairs: Military Exercises, Technology & Global Events to Know

For aspirants preparing for the CDS 2 2026 examination, defence current affairs should be a major part of their General Knowledge preparation. UPSC can connect recent defence developments with static topics such as international relations, geography, military organisations, science and technology, and national security.

From military exercises and indigenous weapons to emerging technologies and changing global security partnerships, 2026 has produced several important developments that CDS aspirants should track. Here is a focused guide to the key areas candidates should revise before the examination.

1. Why Defence Current Affairs Matter for CDS 2 2026

The CDS examination tests more than factual memory. Questions can require candidates to understand why a defence development is important, which countries are involved, which military service participated, and its strategic significance.

For effective preparation, candidates should regularly follow:

• Major military exercises
• Defence acquisitions and agreements
• Missile and weapons technology
• Indian defence production
• Important military operations
• International defence partnerships
• Space and cyber security
• Appointments in defence organisations
• Major global security developments

This approach is particularly useful for students pursuing CDS Preparation in Dehradun, where defence-focused preparation can combine current affairs with regular GK revision.

2. Important Military Exercises to Revise

Military exercises are among the most important topics for defence entrance exams because they combine current affairs with static General Knowledge.

One notable recent exercise is MAITREE-XV 2026, the India-Thailand joint military exercise. The exercise provides an example of how India strengthens military cooperation and shares operational experience with partner nations.

Another important international exercise is Super Garuda Shield 2026, conducted by Indonesia and the United States with participation from several other countries. The 2026 edition included training involving airborne operations, jungle warfare, cyber defence, naval activities and disaster-relief scenarios.

While revising exercises, remember four basic points:

Exercise Name + Participating Countries + Military Service + Location

This simple method can make revision easier for CDS aspirants.

3. Indigenous Defence Technology and Modern Warfare

India’s increasing focus on self-reliance in defence makes indigenous technology an important current-affairs area.

Candidates should revise developments involving:

• Missiles and rocket systems
• Fighter aircraft
• Drones and counter-drone systems
• Air-defence technology
• Electronic warfare
• Surveillance systems
• Unmanned platforms
• Space-based military capabilities

A recent development involves India’s Bharat Forge/Kalyani Strategic Systems and France’s Thales, which signed an agreement to develop and manufacture 70-mm rocket systems in India. The collaboration reflects India’s broader push towards domestic defence manufacturing.

Such developments are important because CDS questions may test not only the weapon or technology but also the concept of Atmanirbhar Bharat in defence.

4. Drones, Cyber Warfare and Electronic Warfare

Modern conflicts increasingly involve technologies beyond conventional tanks, aircraft and artillery. Drones, cyber operations, electronic warfare and satellite-based systems are becoming significant elements of military strategy.

The importance of these areas can also be seen in international military exercises. For example, the 2026 Ulchi Freedom Shield exercises involving the United States and South Korea included scenarios related to drone attacks, GPS disruption and cyber warfare.

For CDS preparation, aspirants should understand basic terms such as UAV, UAS, electronic warfare, cyber warfare, anti-drone systems and satellite surveillance.

5. Space and National Security

Space is rapidly becoming an important component of modern national security. Satellites support communication, navigation, surveillance, intelligence and military operations.

Recent developments involving the United States and China demonstrate growing international attention to space warfare technologies, including manoeuvrable satellites, satellite protection and systems designed to interfere with or disable space assets.

For CDS aspirants, this topic should be studied alongside India’s space and defence capabilities.

6. India’s Defence Diplomacy and International Relations

Defence cooperation is closely connected with India’s foreign policy. Agreements with countries such as France, the United States, Japan, Australia, Thailand and other strategic partners can improve military interoperability, technology cooperation and regional security.

India’s growing defence relationships should therefore be studied as part of both current affairs and international relations.

Candidates should ask:

• Which countries are India’s major defence partners?
• What military exercises does India conduct with them?
• What defence technologies are being developed jointly?
• Why is a particular region strategically important?

This approach helps candidates understand rather than simply memorise current affairs.

7. How CDS Aspirants Should Prepare Defence Current Affairs

Aspirants preparing through a CDS Coaching Institute should avoid trying to memorise every defence-related news story. Instead, focus on important developments and revise them repeatedly.

A practical routine is:

Daily: Read important defence news for 15–20 minutes.
Weekly: Prepare short notes on exercises, technology and international relations.
Monthly: Revise one-month defence current affairs.
Before the exam: Focus on names, dates, participating countries, locations and strategic significance.

Students preparing for Indian Army officer training should also develop an interest in national security and military affairs beyond examination requirements.

8. Prepare with Siddhu Defence Academy
