The sirens will wail. For fifteen minutes, the country will practice survival.
On a Wednesday afternoon in South Korea, sirens will sound for the first time in six years across a nation of fifty-two million, calling citizens into shelters and off the roads in a choreographed rehearsal of survival. The Ulchi civil defence drill, revived amid North Korea's accelerating nuclear ambitions, is both a practical exercise and a philosophical act — a society pausing to acknowledge that danger is not abstract but written into the very architecture of daily life. It is a reminder that preparedness is itself a form of memory, and that memory, left untended, fades.
- North Korea's growing nuclear arsenal and a humiliating false alarm in May have forced South Korea to confront how badly its civilian readiness has eroded over six years of dormancy.
- At 2 p.m., sirens will cut across the entire country — pedestrians ordered into bunkers, drivers pulled to the shoulder, hundreds of public venues emptied — a nation briefly suspended in rehearsed fear.
- Seventeen thousand shelters exist beneath the country's streets and buildings, yet most residents have never entered one, raising urgent questions about whether infrastructure alone constitutes preparedness.
- Border communities face the sharpest edge of the drill, donning gas masks and running chemical, biological, and radiological scenarios that imagine a world where the sirens do not stop.
- Running alongside the joint US–South Korea Ulchi Freedom Shield military exercises, the civilian drill sends a coordinated signal to Pyongyang — but its deeper test is whether six years of absence has erased the muscle memory of a population.
At two o'clock on a Wednesday, sirens will sound across South Korea for the first time in six years. For fifteen minutes, the country will rehearse what it hopes never to need: a nationwide response to an air attack. Pedestrians will shelter in designated bunkers, drivers in roughly two hundred locations will pull to the shoulder, and nearly five hundred public venues will empty into safe rooms. The trains will keep running. The hospitals will stay open. Life will pause, briefly, in a choreographed act of collective memory.
The drill carries the name Ulchi, after a seventh-century Korean general, and has been a fixture of civil defence since 1969 — born from the year a North Korean commando raid reached the gates of the presidential compound in Seoul. Its six-year suspension is now over. With North Korea's missile tests accelerating and its nuclear arsenal expanding, the government has decided that fifty-two million people need reminding of what to do when the warning sounds.
The timing is deliberate. The civilian drill runs alongside Ulchi Freedom Shield, the annual joint military exercise with the United States that began earlier in the week. Together they form a message to Pyongyang. But the civilian component carries its own weight — seventeen thousand shelters are built into the country's infrastructure, tucked beneath apartment buildings and public spaces, most of them never used, most residents never having entered one.
In the regions bordering North Korea, the exercise will be more severe. Residents will don gas masks and rehearse scenarios involving chemical, biological, and radiological threats — communities closest to the danger running drills that reflect that proximity.
The decision to resume full-scale drills follows a sobering episode in May, when a false air raid alarm triggered by a failed North Korean satellite launch sent Seoul residents into panic, despite the rocket posing no threat to the capital. The confusion revealed how quickly alarm becomes chaos and how fragile public confidence can be. This time, the drill is announced. This time, people will know it is coming — and the country will discover whether six years away from the sirens has dulled the instincts that survival, in this corner of the peninsula, still requires.
At two o'clock on Wednesday afternoon, sirens will wail across South Korea. For the next fifteen minutes, the country will practice what it has not done in six years: a nationwide response to an air attack. Pedestrians will be ordered off the streets and into shelters—designated bunkers or underground spaces, whatever is nearest. In roughly two hundred locations scattered across the nation, drivers will pull their cars to the shoulder and wait. Nearly five hundred supermarkets, movie theaters, and other gathering places will empty their customers into safe rooms. The trains will keep running. The hospitals will stay open. Life will pause, briefly, in a choreographed rehearsal of survival.
The drill is called Ulchi, named after a seventh-century Korean general, and it has been a fixture of South Korean civil defense since 1969, born from the year a commando raid penetrated all the way to the presidential compound in Seoul. For the past six years, the country has not conducted a full-scale version. Now, with North Korea's nuclear arsenal growing and its missile tests accelerating, the government has decided the time has come to remind fifty-two million people what to do when the warning sounds. The interior and safety ministry has spent weeks preparing the script. Community centers near apartment complexes in Seoul have already begun announcing the drill over loudspeakers, telling residents not to be startled, to find shelter nearby, to follow instructions that will also air on radio.
The timing is deliberate. The Ulchi drills run alongside Ulchi Freedom Shield, a joint military exercise between South Korea and the United States that began on Monday. Together, they form an annual show of readiness—a message to Pyongyang that the South is prepared, coordinated, and watching. But the civilian component carries its own weight. Across the country, there are seventeen thousand shelters built into the infrastructure, tucked beneath apartment buildings and public spaces, waiting to be used. Most have never been needed. Most residents have never entered one.
In the regions that border North Korea, the drill will be more elaborate. People there will don gas masks and practice scenarios involving chemical, biological, and radiological contamination. They will open emergency rations and imagine a world in which the sirens do not stop after fifteen minutes. These are the communities closest to the threat, and their drills reflect that proximity.
The decision to hold a full nationwide drill comes against a backdrop of recent anxiety. In late May, Seoul issued a false air raid alarm following a failed North Korean satellite launch. The capital was nowhere near the rocket's trajectory, but the mistake triggered panic anyway—people running, confusion spreading, the machinery of fear grinding into motion over nothing. That episode exposed both the fragility of public confidence and the speed with which alarm can become chaos. The government has learned from it. This time, the drill is announced. This time, people will know it is coming.
What remains unclear is whether six years of absence has dulled the muscle memory. Whether the shelters are where people remember them to be. Whether, when the sirens sound, the country will move as one or hesitate, uncertain. The drill will answer some of these questions. It will also serve as a reminder that in this corner of the peninsula, the possibility of attack is not theoretical. It is written into the infrastructure, into the annual calendar, into the collective understanding of what it means to live here. On Wednesday at two o'clock, that understanding will be tested.

Why now? Why revive these drills after six years of not doing them?
North Korea's weapons program has accelerated dramatically. The nuclear tests, the missile launches—they're not slowing down. The government felt the gap had become dangerous, that people had grown too comfortable assuming the sirens would never sound.
But there was that false alarm in May. Wouldn't that make people less likely to trust the system?
Exactly. That's partly why they're doing this now, openly, with warning. They need to rebuild confidence that the system works, that people know what to do. A controlled drill is better than another panic.
What happens to someone who doesn't make it to a shelter in those fifteen minutes?
The drill is designed to be achievable—most people live within walking distance of a shelter. But the real answer is that in an actual attack, fifteen minutes might be all you have. The drill is teaching people to move fast, to not hesitate.
The border regions are doing something different—chemical, biological, radiological training. Are they expecting something worse?
They're closest to the threat. If something happens, it won't be just bombs. It could be anything. So they train for everything.
Do people actually want to do this? Or does it feel like living in fear?
Both, probably. It's become normal here. The shelters are part of the landscape. But normal doesn't mean comfortable. It means you've learned to live with the possibility.
