From Operation Sindoor, Balakot to Beyond: How India’s Air Doctrine Is Evolving

For nearly five decades after 1971, India's strategic response to Pakistan-sponsored provocation followed a consistent and largely predictable pattern: absorb the provocation, exercise restraint, and escalation management. It was a calculated doctrine, shaped by the compulsions of nuclear geography and a strategic culture that placed a premium on stability over assertion.

However, the doctrine could stop the provocation from continuing. Cross-border terrorism continued. The 2001 Parliament attack, the 2008 Mumbai attacks, the 2016 Uri Strike, the 2019 Pulwama bombing, and the 2025 Pahalgam massacre each tested this posture. Restraint was gradually interpreted as strategic tolerance. It was a credibility deficit that would eventually demand a reckoning.

The transformation in India's security doctrine did not happen overnight. It was the product of accumulated frustration, improving military capability & escalation management, and the ability to accept the risks that assertive action entails.

The shift can be traced through three defining operations: the Balakot Airstrike in 2019 and Operation Sindoor in 2025. Each represents a progressively higher rung on India's escalation ladder, and each reflects a doctrine in active evolution.

Balakot 2019: The First Departure

The Pulwama attack of February 2019, which killed 40 Central Reserve Police Force personnel in a suicide bombing claimed by a Pakistani terror group. Twelve days later, the Indian Air Force crossed the Line of Control and struck a JeM training facility in Balakot, the first such strike on Pakistani territory since 1971.

The significance of Balakot was doctrinal as much as operational. India had demonstrated both the will and the capability to conduct offensive air operations across an internationally recognised boundary, in response to a sub-conventional terrorist attack.

In previous instances, India had clearly indicated its threshold of tolerance whilst exercising restraint and symbolic resolve, avoiding striking deep into Pakistan's mainland. Balakot changed that calculus.

Operation Sindoor 2025: A Doctrine Operationalised

Where Balakot was a departure, Operation Sindoor was a transformation. Launched on 7 May 2025 in response to the Pahalgam massacre that killed 26 tourists, the operation represented a fundamental recalibration of both the scope and intent of India's military response to cross-border terrorism.

Operation Sindoor marked a decisive departure in India's previous approach. Unlike the 2016 surgical strikes and the 2019 Balakot airstrikes, this time the response was fundamentally different. India's focus was on dismantling Pakistan's terror infrastructure across the entire operational chain.

The operation was equally significant for what it demonstrated technologically. It was the subcontinent's first non-contact war, marked by technology-driven kinetic activity involving missiles and drones. Neither side physically crossed the other's territorial space. Precision standoff munitions, loitering drones, and a layered multi-domain architecture allowed India to strike with surgical accuracy.

The doctrinal articulation that followed was equally significant. India moved towards a more assertive posture, consolidating its strategy around an evolving doctrine of Proactive Deterrence underpinned by Calibrated Coercive Capability. Its goal was clear: to eschew the reactive past, proactively shape the security environment, and impose costs on adversaries.

The evolved doctrine is not superficial in its nature. It is backed by the Indian Air Force's growing precision-strike capabilities, systematically built over the years, that found their most consequential expression in Operation Sindoor.

India employed weapons such as the BrahMos missile, SCALP, HAMMER, and SPICE 2000 precision-guided munitions across targets ranging from terrorist headquarters in Punjab to forward air bases deep inside Pakistani territory. The induction of Rafale jets from France, which began in mid-2020, provided the IAF with a generational leap in standoff strike capability.

Complementing the Rafale were indigenous and acquired drone systems, including Harop loitering munitions and kamikaze drones, that enabled sustained, precise engagement. The S-400 air defence system provided the layered protective umbrella under which offensive operations could be conducted with greater confidence.

What Operation Sindoor demonstrated, above all, was that India's precision strike architecture had matured from aspiration to operational reality.

Operation Sindoor has established a new threshold, but it has also opened a deeper strategic conversation within India's defence establishment. Many analysts are bringing up the argument that the longer-term answer to cross-border terrorism lies in a doctrine of compellence. Because deterrence manages the cycle, compellence seeks to break it.

That debate is now firmly underway. As India's precision strike capabilities mature and its indigenisation programme deepens, the conditions for a more compellence-oriented posture may emerge. The doctrine is evolving, and Operation Sindoor, in many ways, is best understood not as its culmination but as its most consequential milestone so far.
