    • 150+ tanks and armoured vehicles
    • Over 40 fighter aircraft, including Su-30 MKI and Rafale jets
    • Indian Navy warships and coastal patrol vessels
    • Long-range artillery and air defence missile systems
  • Area Covered: Over 1,000 km from Gujarat’s coastal sectors to the Thar desert in Rajasthan.

Purpose and Strategic Significance

Exercise Trishul tested India’s joint command structure, interoperability among the three services, and integration of land, sea, and air assets under a single battle plan.

  • The Navy simulated blockade operations and amphibious landings near the Sir Creek area.
  • The Air Force conducted precision strikes, logistics airlifts, and aerial surveillance missions.
  • The Army performed armoured thrusts, counteroffensive manoeuvres, and electronic warfare operations.

The overarching goal was to validate India’s capability to wage swift, coordinated operations in case of a two-front conflict, a possibility increasingly discussed in modern strategic circles.

Exercise Astra Shakti – Power in the Skies and Mountains

Astra Shakti, meaning “Power of the Weapon,” was conducted primarily in Ladakh and Arunachal Pradesh, regions that have witnessed heightened tensions with China over the past few years.

Key Highlights

  • Focus: High-altitude warfare, drone swarm tactics, and long-range artillery operations.
  • Altitude Range: Exercises conducted at elevations exceeding 12,000 feet, testing human endurance and logistics efficiency.
  • Troops Deployed: Around 10,000 soldiers, including mountain divisions and special forces.
  • Systems Used:
    • Indigenous drones equipped with reconnaissance and strike capabilities.
    • High-mobility artillery guns (M777 Ultra-Light Howitzers).
    • Multi-barrel rocket launchers and counter-drone systems.

Objectives

The exercise aimed to strengthen India’s operational preparedness along the Line of Actual Control (LAC) with China. It focused on modern war doctrines emphasizing unmanned aerial systems (UAS), network-centric warfare, and long-range precision engagement.

One significant aspect was the integration of satellite-based communication and real-time data-sharing between forward troops and command centres. This represents a major leap in digital battlefield management — a key component of India’s “future warfare vision.”

Exercise Sentinel Strike – The Desert Warfare Test

The third of the triad, Exercise Sentinel Strike, took place in the desert sectors of Rajasthan, focusing on rapid deployment, night-time warfare, and mechanized strike operations.

Key Details

  • Location: Jaisalmer and Barmer regions.
  • Participation: Over 15,000 troops from armoured corps, mechanized infantry, artillery, and aviation wings.
  • Assets Used:
    • T-90 Bhishma and Arjun MK-1A tanks.
    • Self-propelled K9 Vajra howitzers.
    • Combat helicopters including LCH Prachand and Apache AH-64E.
    • Night vision-equipped surveillance drones and radar systems.

Focus Areas

Sentinel Strike concentrated on night operations and high-speed coordinated manoeuvres. The exercises simulated enemy advances and India’s counteroffensive capabilities, emphasizing speed, mobility, and firepower concentration.

The exercise also tested India’s “Integrated Battle Group (IBG)” concept, which allows small, self-contained formations to operate independently with faster decision-making and mobility.

Key Technological and Tactical Advancements

India’s 2025 exercises showcased a leap in the use of modern warfare technology and strategy.
