Defence Current Affairs MCQs

Notes:
The Indian Army conducted the Teesta Prahar exercise today at the Teesta field firing range in West Bengal. This large-scale exercise involved various units like infantry, mechanised infantry, artillery, armoured corps, Para Special Forces, Army Aviation, Engineers, and Signals. It showcased the high level of coordination and joint force integration among different branches of the Indian Army. The aim was to demonstrate operational preparedness and combat-readiness in complex situations. The exercise is significant in the backdrop of Operation Sindoor, which focuses on strengthening India’s security along sensitive borders. Teesta Prahar reflects the Indian Army’s commitment to national defence and rapid response capability.

Notes:
Ukraine’s military intelligence agency recently reported that Russia plans to carry out a “training and combat” launch of the RS-24 Yars intercontinental ballistic missile to intimidate Ukraine and Western countries. The RS-24 Yars, known by NATO as SS-29, is a Russian-made Intercontinental Ballistic Missile (ICBM). It officially entered into service in February 2010 and is a key part of Russia’s strategic missile force. It was developed to replace older ICBMs like the SS-19 Stiletto and SS-18 Satan. The RS-24 Yars is capable of penetrating even the most advanced Ballistic Missile Defense (BMD) systems.

Notes:
The Indian Air Force (IAF) is planning to acquire the ‘Ice Breaker’ missile from Israel. The Ice Breaker is a long-range, air-launched cruise missile with precision guidance and autonomous capabilities. It is developed by Rafael Advanced Defense Systems, a leading Israeli defense company. The missile can be deployed from various platforms, including jet fighters, light attack aircraft, helicopters, small ships, and ground vehicles.

Notes:
The Indian Navy and the Royal Navy of the United Kingdom conducted a Passage Exercise (PASSEX) in the North Arabian Sea on June 9 and 10, 2025. India deployed INS Tabar, a stealth frigate, along with a submarine and P-8I maritime patrol aircraft. The United Kingdom’s Carrier Strike Group included HMS Prince of Wales and frigate HMS Richmond. The naval drill involved helicopter coordination, tactical manoeuvres, anti-submarine warfare, and officer exchanges. This shows deepening defence ties and shared commitment to maritime security.

Notes:
The Indian Army successfully tested Rudrastra, a Hybrid Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicle (UAV) developed by Solar Defence and Aerospace Limited (SDAL). The trial met all Army requirements, including vertical takeoff, high endurance, precision targeting, and mission flexibility. Rudrastra flew over 50 km radius with a stable real-time video link and returned safely to its launch point. Its total range exceeded 170 km with about 1.5 hours of flight endurance. It dropped a precision-guided anti-personnel warhead that detonated in air, showing strong tactical impact.

Notes:
Iran recently used its Fattah hypersonic missile in strikes on Israel, raising global security concerns by bypassing defence systems like Iron Dome. Fattah is a medium-range hypersonic ballistic missile developed by the Aerospace Force of the Islamic Revolutionary Guard Corps (IRGC) of Iran. It was unveiled in November 2022 on the death anniversary of Hassan Tehrani Moghaddam, the father of Iran’s missile program, and inducted in 2023.

Notes:
Recently, the United States entered Israel’s war with Iran by launching precision strikes on Iran’s nuclear sites using Tomahawk cruise missiles and GBU-57 bunker buster bombs. Tomahawk is a long-range, subsonic cruise missile developed by the United States Navy for land-attack missions. It is launched from ships or submarines using a Vertical Launch System for highly accurate strikes. Tomahawks were first used in 1991 during Operation Desert Storm and have been used in several conflicts since then, including Syria in 2017.

Notes:
Recently, the United States used up 15 to 20 percent of its Terminal High Altitude Area Defense (THAAD) missile system stock to defend against Iran’s aerial strikes during a 12-day conflict involving attacks on nuclear sites by Israel and the US. The THAAD system is an advanced missile defence developed by the United States to destroy short-, medium-, and intermediate-range ballistic missiles in their terminal phase. THAAD is a vital part of US Ballistic Missile Defense (BMD) and can intercept targets both inside and outside the atmosphere.

Notes:
Recently, the Indian Navy’s Indian Naval Ship Tabar (INS Tabar) acted quickly to rescue crew members after a fire broke out on an oil vessel in the Gulf of Oman. INS Tabar (F44) is the third Talwar-class frigate of the Indian Navy. It was built in Russia. It is one of the earliest stealth frigates of the Indian Navy. It operates under the Western Fleet based in Mumbai within the Western Naval Command.

Notes:
Recently, the Defence Research and Development Organisation (DRDO) developed India’s first indigenous Photonic Radar. This is a big step for both defence and civilian radar technology. It places India among global leaders in next-generation radar innovation. Photonic Radar uses light-based (photonic) technology instead of traditional electronic signals. This technology gives higher bandwidth and much better resolution. It can detect and identify even the smallest objects with great accuracy.
