1. India to replenish S-400 missile stocks

India is looking to buy S-400 air defence missiles worth around Rs 10,000 crore from Russia to replenish missiles fired during Operation Sindoor. The S-400 air defence system of the Indian Air Force brought down five to six Pakistani fighter aircraft and one spy plane at a distance of over 300 Km deep inside Pakistan during the four-day conflict and has been termed as a game-changer by the Indian Air Force.

"The Indian Air Force is looking to buy the missiles in significant numbers to further bolster its air defence capabilities. The discussions with the Russian side are already on in this regard," according to ANI.

2. India Japan conduct Exercise JAIMEX-2025

Indian Naval Ship (INS) Sahyadri, an indigenously built Shivalik-class Guided Missile Stealth Frigate, participated in the Sea phase of JAIMEX-25 (Japan India Maritime Exercise) from 16 to 18 Oct 2025 and made a port call at Yokosuka, Japan, on 21 Oct 2025 for the Harbour phase. 

Prior arriving at Yokosuka, INS Sahyadri and JMSDF Ships Asahi , Oumi and Submarine Jinryu participated in the sea phase of JAIMEX 25. The sea phase8 included advanced Anti-Submarine Warfare and missile defence drills, enhancing interoperability by undertaking flying operations and underway replenishment.
 

3. North Korea fires ballistic missile before leaders meet.

North Korea fired multiple short-range ballistic missiles on October 22, South Korea's military said, a week ahead of a key Asia-Pacific leaders' meeting in South Korea.

It was the first launch of ballistic missiles since May by Pyongyang, which has defied an international ban backed by the U.S. and South Korea on such weapons development.

South Korean President Lee Jae Myung and U.S. President Donald Trump are expected to meet in South Korea next week at a summit meeting of the Asia-Pacific Economic Cooperation (APEC) forum. Trump is also expected to meet with Chinese President Xi Jinping.

4. US Army orders nine CH-47F Chinook Block-II

The U.S. Army is advancing its heavy-lift modernization efforts by ordering nine Boeing CH-47F Block II Chinooks via two contract awards. The Lot 4 and 5 awards, valued at $461 million, increase the number of CH-47F Block II aircraft under contract to 18.

To date, Boeing has delivered six CH-47F Block II production helicopters to the Army, which are currently undergoing a series of evaluations to demonstrate their enhanced capabilities . The CH-47F Block II features significant upgrades, including an improved drivetrain and airframe that increase the maximum gross weight by 4,000 pounds, significantly increasing lift capability. The Indian Air Force operates 15 Boeing CH-47F(I) Chinooks.

5. General Atomics tests LRMP from M777 howitzer.

General Atomics said it successfully tested its new Long Range Maneuvering Projectile (LRMP) at the U.S. Army’s Yuma Proving Ground. In a series of launches in August, LRMP rounds were fired from an M777 howitzer using M231 propellant charges. The tests verified key flight phases — pallet separation, spin stabilization, deployment of aerodynamic surfaces, and controlled descent according to a report from militarnyi.com.

The LRMP is a next-generation precision-guided munition intended to expand the reach and flexibility of 155 mm artillery systems. Equipped with controllable aerodynamic surfaces and onboard navigation, the projectile can maneuver in flight and engage targets even if GPS is denied. After firing, the round reaches an apogee of about 12–13.7 km. Its expected range is roughly 120-150 km. The Indian Army operates 145 M-777 howitzers and has used them in Operation Sindoor.

6. Hanwha unveils K-NIFV at ADEX 2025

Hanwha Aerospace unveiled the Korea New Infantry Fighting Vehicle, or K-NIFV, a next-generation tracked IFV derived from the Redback platform at the ADEX 2025 in Seoul, according to a report by ArmyRecognition. The AS-21 Redback platform was selected by the Australian Army to replace its ageing M113AS4 under its Land 400 Phase 3 program over the German Rheinmetall KF-41 Lynx IFV in July 2023. The biennial event is a major global showcase for the defense and aerospace industries, featuring both indoor and outdoor exhibitions and flying demonstrations.

On the Hanwha stand, the company emphasized a new unmanned turret armed with a 30 mm cannon and growth to a 40 mm cased-telescoped gun, plus provision for an indigenous anti-tank missile. The headline feature is a multi-layered counter-drone suite that fuses radar-guided remote weapons, AI-assisted sights, and a hard-kill active protection system. Hanwha says the design raises domestic content and lowers life-cycle costs while preserving Redback-level protection and mobility. HHanwha supplies the K-9 Vajra howitzer in collaboration with L&T for the Indian Army.

7. Hanwha unveils HPRS system at ADEX-2025.

Hanwha unveiled its High Performance Rocket System, HPRS, at Seoul ADEX 2025 on 21 October 2025, displaying a compact 6x6 single-pod launcher that accepts CTM family missiles. The system trades the Chunmoo’s twin-pod footprint for a four-round sealed pod and high-accuracy CTM MR rounds (50–160 km, ≈9 m CEP) according to a report by ArmyRecognition.

The launcher carries one sealed pod with four CTM missiles, a format that mirrors the Chunmoo’s two-pod layout but halves the footprint for expeditionary use. The primary round highlighted for HPRS is the CTM MR, a GPS and inertial guided ballistic missile with a stated range envelope from roughly 50 to 160 kilometers and a circular error probable quoted at around nine meters.
