In an era dominated by drone warfare, satellite-guided missiles, and AI-powered surveillance systems, wartime blackouts may sound like a relic of the past. However, in 2025, this age-old civil defense tactic is proving to be more relevant than ever. As India conducted mega-security drills across 244 districts on May 7, the spotlight is once again on this critical practice, designed to protect lives and infrastructure in times of military threats.
What is a Wartime blackout?
A wartime blackout is a defense measure implemented during times of military conflict where all artificial lights streetlights, home lights, vehicle headlights, and even electronic screens are turned off or heavily dimmed. The primary goal is to hinder visibility for enemy forces such as aircraft, drones, or submarines, making it difficult for them to locate and target populated or strategically important areas.
This method, historically used during World Wars, is now being revisited in modern times due to the increased threat of precision attacks using advanced surveillance and targeting technology.
Why Wartime Blackouts still Matter in 2025
Despite advancements in radar and satellite imaging, visible light remains a key indicator for enemy forces attempting to identify targets during night-time operations. Here’s why blackout protocols are vital today:
1. Rise of drone warfare and smart weapons
2. Civil preparedness and emergency response
3. Protecting infrastructure
Real-Life examples: When Blackouts were important
India's 1971 war with Pakistan
During the Indo-Pak war of 1971, cities like Delhi, Mumbai, and Kolkata went into blackout mode at night. Citizens were instructed to switch off all lights to prevent detection by Pakistani bombers. Public buildings and homes used thick curtains and low lighting to avoid standing out. These measures significantly reduced civilian casualties and confusion during air raid alerts.
Balakot air strikes, 2019
On February 26, 2019, when India conducted airstrikes on terror camps in Balakot, Pakistan, tensions along the border surged. Border villages in Punjab and Jammu & Kashmir were put on high alert. Though not a full-scale blackout, partial lighting restrictions were implemented in sensitive zones to enhance preparedness in case of a retaliatory strike.
What happens during a modern blackout?
- Turning off unnecessary home and street lights
- Drawing blackout curtains to block light leakage
- Dimming or switching off the phone and television screens
- Avoiding vehicle usage unless necessary
- Using minimal indoor lighting, often with covered torches or emergency lights
- Such readiness can mean the difference between panic and protection in a high-risk situation.
