Why in News On May 11, 2026, the Indian Armed Forces held an anniversary press conference in Jaipur to mark one year since Operation Sindoor (May 7-10, 2025). Unlike the May 9 anniversary review that focused on the strategic doctrine shift, this assessment by the three services highlights what has been institutionalised in a year – specifically the lessons in tri-service integration, electronic warfare, drone-and-counter-drone warfare, and intelligence-strike kill chains.
Background: From Pahalgam to Sindoor in 15 Days
The trigger, as historical background since 2025, was the Pahalgam terror attack of April 22, 2025, in which 26 civilians were killed at the Baisaran meadow above Pahalgam in Anantnag district, Jammu and Kashmir. The Resistance Front (TRF) – a Lashkar-e-Taiba front – claimed responsibility. Indian intelligence traced planning to Pakistan-based outfits with ISI handlers.
After a 15-day diplomatic and operational build-up, India launched Operation Sindoor, launched in 2025 on the night of May 6-7, 2025.
| Phase | Dates | Action |
|---|---|---|
| Phase 1 | May 7, 2025 | Strikes on 9 terror infrastructure sites in Pakistan + PoJK |
| Phase 2 | May 8-9, 2025 | Pakistan counter-strikes (drones/missiles); India’s air defences engage |
| Phase 3 | May 9-10, 2025 | India strikes 11 Pakistani military airbases |
| Phase 4 | May 10, 2025 (17:00 IST) – since 2025 a key reference date | Ceasefire via DGMO hotline |
The Strike Targets: Decapitating Terror Headquarters
The 9 sites struck on May 7, 2025 (launched in 2025) were chosen explicitly to hit organisational HQs rather than peripheral training camps:
| Site | Significance |
|---|---|
| Bahawalpur (Punjab, Pakistan) | HQ of Jaish-e-Mohammed (JeM) – Markaz Subhan Allah |
| Muridke (Punjab, Pakistan) | HQ of Lashkar-e-Taiba (LeT) – Markaz Taiba |
| Kotli, Muzaffarabad, Bhimber (PoJK) | LeT/JeM logistics and training |
| Sialkot district sites | Forward staging |
| Gulpur, Bagh (PoJK) | HuM and LeT camps |
Hitting Bahawalpur and Muridke – both deep inside Pakistan’s Punjab heartland – was the operation’s most striking signalling element.
The Technology Stack: What Was Used
| Weapon / System | Role |
|---|---|
| Rafale + SCALP | Stand-off cruise strikes from beyond Pakistani air defence range |
| HAMMER PGM | Modular precision-guided munitions on Rafale; high accuracy at medium range |
| BrahMos cruise missiles | Supersonic stand-off (Mach 2.8+) strikes |
| Akashteer integrated air defence | Networked battle management for Army air defence |
| S-400 Triumf | Long-range SAM cover against Pakistani aerial counter-attacks |
| Akash and MR-SAM | Medium-range air defence |
| Loitering munitions (SkyStriker, Harop) | Anti-radiation and precision targeting |
| Indigenous drones + counter-drone systems | Surveillance, kinetic effects, and intercepts |
| EW suites (Tarang, Samyukta upgrades) | Jamming, deception, suppression of enemy air defences |
| Space-based ISR (RISAT, EMISAT) | Real-time targeting and damage assessment |
One-Year Institutionalisation: What Has Changed
1. Tri-Service Integration – Towards Theatre Commands
Operation Sindoor was executed by all three services under a synchronised plan. In the year since, the move towards integrated theatre commands – long debated but stalled – has accelerated. The Department of Military Affairs (DMA) under the CDS has fast-tracked common doctrine documents, joint logistics, and harmonised C4ISR.
2. Electronic Warfare and Network-Centric Warfare
The operation validated Akashteer as a network-centric air defence success. The Army has expanded Tarang EW deployments along the Western front. The Air Force has accelerated procurement of indigenous SEAD/DEAD (suppression and destruction of enemy air defences) capabilities.
3. Drone-and-Counter-Drone Warfare
Pakistan’s counter-strike relied heavily on Turkish-origin Asisguard Songar and Chinese-origin systems. India’s response validated the CAATS (Counter-Aerial Attack on Terror Sites) doctrine. The DRDO indigenous counter-drone system has been mainstreamed across forward bases.
4. Intelligence-to-Strike Kill Chain
The 25-minute Phase 1 strike window required real-time fusion of HUMINT, SIGINT, IMINT, and SATINT. The Defence Intelligence Agency (DIA) is being restructured to formalise this fusion under a joint architecture.
5. Sub-Threshold Doctrine
A standing operational template has been issued for calibrated, precise, stand-off strikes against terror infrastructure – below the threshold of full conventional war but above the previous restraint baseline.
Diplomatic Architecture of the Anniversary
- P5 outreach continues; India’s case rests on the documented terror infrastructure at Bahawalpur and Muridke
- Indus Waters Treaty remains in operational suspension; revival contingent on Pakistan-side terrorism action
- FATF scrutiny of Pakistan revived in the wake of Sindoor evidence
- India’s narrative: a precise, proportionate, sub-threshold response – not aggression
Concerns Raised Domestically
| Concern | Description |
|---|---|
| Civilian casualty risk in deep strikes | Bahawalpur and Muridke are populated; precise PGMs mitigated but did not eliminate the risk |
| Escalation control | A future strike must again manage the risk of full-spectrum response |
| Theatre command rollout | Inter-service turf battles still unresolved |
| Budgetary trade-offs | Capital procurement vs. operational readiness |
