Hårsfjärden disaster

The Hårsfjärden disaster was an event in the Swedish Navy during World War II.

A series of accidental explosions, it caused by far the worst damage to Swedish Navy units during the era of that war, in which Sweden was not a combatant.

[1] Three Swedish Navy destroyers were berthed in Hårsfjärden fjord near Stockholm when the torpedoes[2] or oil tanks[3] of Göteborg exploded; flames then also enveloped Klas Horn and Klas Uggla in an inferno.

[2][4] The three destroyers were sunk,[4] and thirty-three sailors killed, a major blow to the Swedish Navy.

Theories also emerged that the cause was a bomb dropped accidentally by a Swedish plane on training maneuvers, or a torpedo demonstration gone wrong.
