New Delhi, June 1 -- The Centre is working to set up modern air-raid warning systems across India's vulnerable districts under the Air Raid Warning System (ARWS) project and has begun recruiting former Indian Air Force (IAF) officers with expertise in air defence operations to lead the initiative, according to officials aware of the matter. When complete, the project will ensure that all 244 vulnerable districts (mostly near the borders) have a standard, modern, and fully functional warning network to alert civilians in the event of aerial threats, including drones, missiles, and aircraft. "The project will ensure that there is a standard air warning system on the ground in accordance with what the civil defence manual mentions. The initiative to establish a new warning system was proposed just after Operation Sindoor last year. The use of drones in warfare mandates having air defence warning systems for civilians. Once this is established, the training of the civilian volunteers too will be tweaked in keeping with the changes over the years and learning from Op Sindoor," an official aware of the matter said. HT had on July 14, 2025, reported that after completion of the drills, held on May 7, April 22 and June 30 against the backdrop of a looming war with Pakistan following the Pahalgam attack, an internal assessment found that most air-raid warning systems were found to be faulty; the ones that existed were non-functional and had to be replaced with temporary sirens. "vintage, old, needed review and done in a slapdash manner." The Directorate General (Fire Service, Civil Defence & Home Guards), a federal agency under the Home Ministry, is leading the project and hiring experts from the IAF who have worked extensively in air defence operations, radar systems and air-raid warning procedures....
