The Tri-Services Exercise (TSE-2025) "Trishul" commenced on Monday, November 3, with the Indian Navy taking the lead in large-scale joint drills.

These extensive exercises are unfolding across diverse and strategically vital regions, including the creek and desert sectors of Rajasthan and Gujarat. The drills also extend into the northern Arabian Sea, covering approximately 1,000 nautical miles of maritime operations, according to Zee News on November 3, 2025.

The primary objective of "Trishul 2025" is to validate joint operational procedures and enhance interoperability among the three services. The Ministry of Defence stated that it seeks to strengthen network integration and enable multi-domain integrated operations, as noted by The Tribune.

Described as India's biggest military exercise since Operation Sindoor, "Trishul" has mobilized tens of thousands of troops. Deccan Herald reported on November 2, 2025, that over 50,000 personnel are participating, alongside major naval assets and more than 40 combat jets.

A key focus of the exercise is the disputed Sir Creek area, a sensitive tidal estuary near the India-Pakistan border. This strategic location underscores the drill's importance in signaling India's readiness to address regional security challenges, as highlighted by Deccan Herald.

The exercise also emphasizes joint Intelligence, Surveillance and Reconnaissance (ISR), Electronic Warfare (EW), and Cyber Warfare operations. The Hindu reported on November 2, 2025, that the drills will also showcase the effective employment of indigenous systems, aligning with the "Aatmanirbhar Bharat" initiative.

Running until mid-November, "Trishul 2025" involves principal formations like the Army's Southern Command, the Navy's Western Naval Command, and the Air Force's South Western Air Command. The Indian Coast Guard and Border Security Force are also participating, reinforcing inter-agency coordination, according to sakshipost on November 2, 2025.

• Strategic Context and Historical Precedent: Exercise Trishul is being conducted six months after "Operation Sindoor," marking it as India's largest tri-service drill since that prior operation, as reported by Deccan Herald on November 2, 2025. This reflects a continuous and evolving operational posture rather than just routine training, with some analysts drawing parallels to the significant "Brass Tacks IV" exercise of 1987, which also caused considerable regional attention, as noted by The Indian Express on November 2, 2025.

• Multi-Domain Integration and Advanced Capabilities: The exercise is designed to test and validate inter-service coordination across land, air, sea, and cyber domains, reflecting India's strategic posture of "JAI" (Jointness, Atmanirbharta, Innovation), according to Exercise Trishul, Purpose, Location, Participation, Drills, Response on October 30, 2025. It integrates modern capabilities such as unmanned aerial vehicles (UAVs), electronic warfare (EW) assets, cyber operations, and space-based ISR, as detailed by the same source.

• Deployment Scale and Key Assets: The scale of "Trishul 2025" is immense, involving more than 50,000 troops, as stated by Zee News on November 3, 2025. Key assets include India's indigenous aircraft carrier INS Vikrant, amphibious ship INS Jalashwa, submarines, and approximately 20-25 naval ships, along with over 40 combat jets such as Rafales, Sukhoi-30MKIs, and Jaguar strike aircraft, according to Deccan Herald.

• Focus on Sir Creek and Regional Implications: The exercise's focus on the Sir Creek region is particularly significant, following Defence Minister Rajnath Singh's recent warning that any aggression in the area would be met with a response that could "change both history and geography," as reported by Zee News. This strategic emphasis serves as a clear deterrence signal to adversaries along the western border, as highlighted by Organiser on November 3, 2025.

• Operational Phases and Inter-Agency Coordination: The Trishul exercise is structured into three phases, with each service leading a distinct phase: the Indian Navy focusing on coastal defense, the Army on land-based operations, and the Air Force on air superiority, as explained by India Begins Tri-Service Exercise 'Ex Trishul' with IAF and Navy Across Western Front on October 31, 2025. Beyond the three main services, the Indian Coast Guard, Border Security Force, and other central agencies are also participating, ensuring robust inter-agency coordination, according to The Hindu.

• Enhancing Interoperability and Networked Operations: A core aim is to enhance interoperability and strengthen network integration among the services, enabling joint effect-based operations in a multi-domain environment, as stated by The Tribune. Vice Admiral A.N. Pramod, Director General of Naval Operations, described Trishul as a "complex, multi-domain exercise" involving cutting-edge amphibious and joint combat operations, according to 25 Warships, 40 Aircraft, 40000 Troops: India's Massive Exercise Trishul Underway on November 2, 2025.

• Impact on India's Strategic Posture: The underlying message of Exercise Trishul is that India is preparing for continuous and multi-front readiness, transitioning from a deterrence posture to one of dominance and proactive control, as analyzed by Zee News. The drills are expected to shape India's strategic landscape for years, with military headquarters already describing this as the "new normal," according to the same source.
