Op Sindoor lessons: From operations to plugging industry gaps & exposing Pakistan-based groups, India more prepared now

Operation Sindoor, the most definitive military strike on Pakistan in more than five decades to punish it for sponsoring terrorism, dominated India’s security discourse in 2025 and laid down new red lines on how the country would respond to terrorist attacks on its soil. The hard lessons drawn from the circumstances that led to cross-border tensions — the state of preparedness in the run-up and the conduct of combat operations —are now set to shape national security choices in 2026. A look at the year gone by, and how it marked a significant shift in military thinking and preparedness for the future.

The Intent

The terrorist attack in Pahalgam on April 22 shocked not just India but the world with its brutality — at an idyllic holiday destination, men were rounded up and separated from their families, identified as Hindus and shot dead in front of their wives, children and mothers. The intent behind the massacre became clear almost immediately. In conversations with the victims’ families, terrorists delivered a chilling message aimed squarely at India’s political leadership, signalling that the scale and savagery of the assault were designed to provoke a forceful military response.

The larger game behind provoking such an attack, however, took longer to unravel. As things stand today, the Pakistan Army has emerged as the primary beneficiary of both the attack and India’s response: its chief, Asim Munir, has elevated himself to the rank of Field Marshal, forced the political leadership to grant him the position for life, and now functions as Pakistan’s de facto ruler. This is a world apart from where the Pakistan Army stood two years ago, when its public image was at its lowest, with unprecedented street protests targeting military installations after the arrest of former PM Imran Khan, including the burning of the Lahore Corps Commander’s residence.


In terms of morale, too, 2023 marked a low point in over a decade, with a string of attacks and high-profile raids on Pakistan Army installations by Baloch separatists and Tehreek-e-Taliban militants. Pakistani military casualties surged to levels not seen since 2014, underscoring just how fragile the army’s grip had become before it sought to reclaim its centrality through a calibrated escalation and manufactured crisis.

Key Lessons

India’s key lesson from the radical turnaround in Pakistan Army’s fortunes is that the military ecosystem in the neighbouring country is willing to stake everything, including the risk of a full-blown war, when it senses its grip on the nation’s pulse weakening. The more critical lesson, however, is that India can now call out Pakistan’s nuclear bluff and execute punishing conventional strikes at the very heart of Rawalpindi’s power centre. Yet, even after absorbing military punishment, the Pakistan Army will continue to claim victory before its domestic audience, masking losses and focusing more on the internal narrative.

For India, this combination of exposed nuclear bluff and predictable Pakistani narrative management creates a new strategic opportunity — the ability to carry out impactful, repeatable strikes against terrorist infrastructure anywhere on Pakistani soil. This erodes the protective cover Islamabad believed it had secured once it went openly nuclear in 1998.

The Operations

India’s military campaign, which opened with precise strikes on terrorist infrastructure — including Lashkar-e-Taiba and Jaish-e-Mohammed headquarters — and then rapidly escalated to heavily defended targets such as air bases, radar sites and command-and-control centres, unfolded against the backdrop of unprecedented changes on the modern battlefield. The advent of low-cost unmanned systems, growing importance of information and cyber warfare, and the decisive role of electronic countermeasures in kinetic operations, have transformed how conventional forces fight, and the 2025 campaign became an early, live test of how India had been adapting to this shift.

From the moment political clearance was given on April 23 to the opening wave of strikes on May 7, armed forces maintained tight operational secrecy. Combat assets were quietly redeployed from the China front to the western theatre — including Rafale fighter jets, M777 ultralight howitzers, heavy armour and additional troops — without triggering the usual chatter that accompanies a visible build-up. Internal social media monitoring cells worked overtime to ensure that no photographs or videos of these movements leaked into the public domain, while specialised soldiers and equipment were pulled in from across the country, including naval kamikaze drones repurposed for the land battle, under a single, tri-services plan.

What underpinned this effort was a clarity of political purpose: the engagement and destruction of terrorist targets and, if necessary, the neutralisation of those providing them protective cover. The outcome — the public and verifiable destruction of nine major terrorist camps, followed by a series of Pakistani military targets that were hit after they attempted to shield these organisations — demonstrated that Indian forces can strike well-defended targets deep inside Pakistan almost with impunity, even when the Pakistani military is on full alert.

Future Ready

While the operations were a clear military success — with several Pakistani military targets destroyed, airfields disabled, radar sites decommissioned and naval assets effectively bottled up — the value lies in the lessons learned that are already reshaping India’s preparation for future conflicts. As things stand, India’s conventional strength is sufficient to place its western neighbour under severe military pressure within days — any conflict will impose costs on India, but those costs remain within a politically and militarily bearable range.

Indian Air Force did not lose any combat personnel during the operation, even as there were multiple recorded casualties at Pakistani air bases. All Indian fighter losses occurred on the first day, during the opening strikes on terrorist targets, with each pilot ejecting safely and landing on home soil. These losses can be linked to intelligence gaps on two air defence systems deployed in Pakistan and on a Chinese origin networked kill-chain that was used operationally for the first time. Once understood, this architecture proved to be a one-trick pony, with countermeasures quickly incorporated into subsequent Indian strikes.

By the third day of the conflict, Indian forces had established near-complete dominance over Pakistani airspace, striking key airfields and disabling runways across the country. The cumulative on-ground damage — from hangars with airborne early warning aircraft, drones and fighters to hardened command-and-control centres and air-defence systems — effectively knocked the Pakistan Air Force out of the fight. Pakistan’s post-conflict fixation on highlighting Indian fighter losses stems from this reality: the only “win” it can extract from a devastating exchange is that some Indian jets were shot down on the first day, while carefully omitting the facts that the primary mission of punitive cross-border strike was successful, there were no Indian combat fatalities and the subsequent three days showcased the Indian Air Force’s complete domination of the aerial battlefield.

The campaign validated India’s emphasis on long-range precision weapons such as BrahMos and SCALP, while demonstrating the payoff from investments in high-end air defence systems like S400. Over the coming year, more such systems are expected to be inducted, with a focus on accelerating indigenous programmes such as the Kusha long-range air defence system and home-grown medium-to-long range hypersonic missiles.

One of the most striking takeaways was the performance of drones and loitering munitions. A post-conflict review showed that a significant proportion of Indian loitering munitions and drones fell short of mission objectives due to heavy jamming and spoofing from across the border. Pakistan fared even worse: all of its drones, including Turkish-origin systems, were either jammed, spoofed away from military targets or shot down, underlining both the vulnerability of current-generation platforms and the growing sophistication of Indian electronic warfare

India compensated for these limitations through mass and firepower, employing large numbers of platforms alongside heavier munitions, including air-to-ground missiles and precision artillery. The lesson, however, is stark: low-cost unmanned systems must be upgraded and adapted quickly to survive in heavily contested electromagnetic environments.

Industry-military synergy

Aquiet but transformative feature of the operation was the presence of Indian defence industry representatives inside the loop. Several domestic firms supported the armed forces in real time from forward locations, pushing software patches, tweaking systems and incorporating battlefield feedback on the fly — a level of integration that has given them a head start in designing more resilient weapons and sensors for the next cycle of conflict. This synergy is the product of sustained, four-year-long effort by the defence ministry to change mindsets in both uniformed and industrial communities, moving from arm’s length procurement to co-development and co-fighting models.

The armed forces have been equally quick to internalise the electronic warfare lessons. Recent trials for indigenous surveillance drones and loitering munitions have been conducted under intense jamming and spoofing conditions that mirror the Operation Sindoor environment, rather than in sanitised test ranges. There is a renewed focus on more robust counter-drone architectures — from swarm-defence solutions to directed-energy and laser-based systems — aimed at ensuring that the next round of conflict sees India not just coping with, but shaping, the drone and electronic warfare battle.

Perhaps the biggest real-world lesson on the industry front is the need for a swiftly scalable indigenous production base. Just over a week after the Pahalgam attack, and days before Operation Sindoor was launched, a hush-hush meeting was convened at the imposing Manekshaw Centre in New Delhi to map the depth and resilience of India’s defence industrial capacity. The brief was blunt: assess how far industry can support the armed forces in a short, limited conflict, in a drawn-out war and, in the worst case, a prolonged confrontation that would demand an all-of-nation effort.

The takeaways from that interaction are now being hardwired into the defence ministry’s procurement and research and development strategy. In the past few weeks, several dozen contracts have been placed under emergency financial powers, alongside a determined push to create multiple, geographically dispersed production lines across different companies that can be activated for surge manufacturing, if required.

Focus 2026: Delivery

If 2025 was marked by radical reforms in procurement policy, new military-industry synergy and unprecedented operational flexibility granted to armed forces by the political leadership, 2026 will be watched closely for outcomes. At the centre of this scrutiny will be the ability of the industry to deliver on its promises — from on-time handover of weapon systems, especially emergency procurements cleared in the past few months, to research organisations fielding cutting-edge, on-the-fly solutions to emerging battlefield challenges, and the defence ministry’s success in fostering genuine surge capacity into the industrial base.

One thing has been made clear: the government now intends to hold industry strictly accountable for what it commits. Delays and slip-ups will not be indulged as routine costs of doing business, and a few hard examples are likely in the coming months to signal that India’s defence industry must either shape up and deliver, or risk being sidelined at a time when national security can least afford underperformance.
