A B83 over Pyongyang
A 1.2-megaton B83 airburst over the centre of Pyongyang, around Kim Il-sung Square and the Taedong river. Pyongyang is a compact city of roughly 3 million people, rebuilt after the Korean War on a grid of wide avenues and high-rise blocks, and a weapon of this size covers almost all of it. The 3 km zone of total destruction takes in the square, the Grand People's Study House, the Juche Tower across the river and the government quarter; the 7.4 km collapse ring reaches Kim Il-sung Stadium, the Ryugyong Hotel and the Mansudae hill.
Third-degree burns extend to about 13.5 km, beyond the full built-up area from Mangyongdae in the west to Sadong in the east, and the 1 psi ring of 23 km includes Sunan airport, Kangdong and the surrounding farmland. The hills around the city are low and would give little shelter from the thermal flash.
During the Korean War Pyongyang was almost entirely destroyed by conventional bombing, which is part of why the North Korean state built its own arsenal; see Nuclear arsenals. North Korea's own 2017 test was estimated at well over 100 kilotons — a tenth of this weapon.
