The ammunition depot at Kalynivka, near Vinnytsia, Ukraine, underwent a series of multi-kiloton explosions that started on the evening of September 26, 2017 [1] [2] and continued burning until September 30. [3] In 2021 the Prosecutor General announced that evidence confirmed sabotage. [4]
The Kalynivka ammunition depot is one of the largest arsenals of the Ukrainian military. [1]
According to the Defense Minister, Stepan Poltorak, about 83,000 tons of ammunitions were stored at the site, about 63,000 tons of it usable consisting primarily of tank ammunition. [5] The explosions forced the temporary evacuation of about 24,000 [6] or 30,000 people. [1] Air space was closed and trains diverted. There was damage to property in the area but no fatalities were reported. [5]
The cause of the explosions remained unclear, however, Ukraine's domestic intelligence believed the explosions to be an act of sabotage, [1] and a presidential advisor suggested that a drone may have started it. [1] The secretary of the Ukrainian Security and Defense Council, Oleksandr Turchynov, noted that the military arsenals have many safety violations. [6] Prime Minister Volodymyr Groysman indicated the need for a thorough investigation and opined "This is the arsenal of the Ukrainian army, and I think it was no accident that it was destroyed." [7]
Ukraine’s State Emergency Service reported on September 30 that "uncontrolled explosions" and the fire had been halted. [3]
On October 2 Kalynivka's schools resumed their school year. [8]
The Kalynivka ammunition explosion was the second major explosion in 2017 of a Ukrainian ammunition depot. The earlier one took place in March at a depot at Balakliia near Kharkiv necessitating the evacuation of about 20,000 people. [1] [2] The destruction at these two ammunition depots is reported to have reduced the combat capability of the Armed Forces of Ukraine. [6]

There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.

At approximately 12 p.m. local time on Saturday, March 15th, 2008, an ex-military ammunition depot in the village of Gërdec in the Vorë Municipality of Albania, U.S. and Albanian munitions experts were preparing to destroy stockpiles of obsolete ammunition. The methodical destruction of the old ammunition was supposed to occur with a series of small, controlled explosions. However, a chain of events led to the entire stockpile detonating simultaneously. Hundreds of houses were demolished within a few kilometres of the depot, while car windows on the Tirana-Durres highway were shattered by the main explosion, which involved more than 400 tonnes of propellant in containers. A large fire caused a series of smaller but powerful explosions that continued until 2 a.m. on Sunday. The explosions could be heard as far away as the North Macedonian capital of Skopje, 170 km (110 mi) away.

The Ukrainian intelligence services have acknowledged carrying out some of these attacks. Others have been carried out by anti-war activists in Russia. There have also been cross-border shelling, missile strikes, and covert raids from Ukraine, mainly in Belgorod, Kursk, and Bryansk oblasts. Several times, Ukrainian-based paramilitaries launched incursions into Russia, captured border villages and battled the Russian military. These were carried out by units made up mainly of Russian emigrants. While Ukraine supported these ground incursions, it denied direct involvement.

The main explosion caused a 82m-wide crater and a seismic wave of magnitude 2.5~2.8 on 18 September, 3:56 am, local time. Such supply chain disruption could reduce Russia's firepower in its war effort in Ukraine.
