The Halifax Explosion was a disaster that occurred in Halifax, Nova Scotia, Canada, on the morning of 6 December 1917. SS Mont-Blanc, a French cargo ship laden with high explosives, collided with the Norwegian vessel SS Imo in the Narrows, a strait connecting the upper Halifax Harbour to Bedford Basin. A fire on board the Mont-Blanc led to a massive explosion that devastated the Richmond district of Halifax. 1,782 people were killed, largely in Halifax and Dartmouth, by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest human-made explosion at the time, releasing the equivalent energy of roughly 2.9 kilotons of TNT (12 TJ).
The Norwegian campaign describes the attempt of the Allies to defend northern Norway coupled with Norwegian forces' resistance to the country's invasion by Nazi Germany in World War II.
The Battle of Vågen was a naval battle between a Dutch merchant and treasure fleet; and an English flotilla of warships in August 1665 as part of the Second Anglo-Dutch War. The battle took place in Vågen, the main port area of neutral Bergen, Norway. Due to a delay in orders, the Norwegian commanders took the side of the Dutch, contrary to the secret intentions of the King of Norway and Denmark. The battle ended with the retreat of the English fleet, which was much damaged but had lost no ships. The treasure fleet was relieved by the Dutch home fleet 17 days later.
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.
HNoMS Garm was the third destroyer built for the Royal Norwegian Navy, and was a Draug class destroyer. Garm was constructed several years after her two sister ships, but to the same plans. She was built at the naval shipyard in Horten, with yard number 107.
The minelayer HNoMS Olav Tryggvason was built by the naval shipyard at Horten in the early 1930s and had build number 119. She served in the Royal Norwegian Navy until captured by the Germans in 1940. The Germans renamed her first Albatros II, and a few days later Brummer. She was wrecked in a British bombing raid in northern Germany in April 1945.
Kvarven Fort was a mountain fort strategically located by the main shipping channel of the Byfjorden leading to Bergen, Norway.
SF Hydro was a Norwegian steam powered railway ferry that operated in the first half of the 20th century on Lake Tinn in Telemark. It connected with the Rjukan Line and Tinnoset Line, at Mæl and Tinnoset, operating between 1914 and 1944. The combined track and ferry service was primarily used to transport raw materials and fertilizer from Norsk Hydro's factory at Rjukan to the port in Skien. It was the target of a Norwegian operation on 20 February 1944, when resistance fighters sank the ferry in the deepest part of Lake Tinn to prevent Nazi Germany from receiving heavy water.
German submarine U-255 was a Type VIIC U-boat that served in Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 21 December 1940 at the Bremer Vulkan yard at Bremen-Vegesack, launched on 8 October 1941 and commissioned on 29 November 1941 under the command of Kapitänleutnant Reinhart Reche.
HMS Glatton and her sister ship Gorgon were originally built as coastal defence ships for the Royal Norwegian Navy, as Bjørgvin and Nidaros respectively. She was requisitioned from Norway at the beginning of World War I, but was not completed until 1918 although she had been launched over three years earlier. On 16 September 1918, before she had even gone into action, she suffered a large fire in one of her 6-inch magazines, and had to be scuttled to prevent an explosion of her main magazines that would have devastated Dover. Her wreck was partially salvaged in 1926, and moved into a position in the northeastern end of the harbour where it would not obstruct traffic. It was subsequently buried by landfill underneath the current car ferry terminal.
SS Irma was a 1,322-ton steamship built by the British shipyard Sir Raylton Dixon & Co. Ltd. in Middlesbrough in the north-east of England. She was delivered to the Norwegian passenger ship company Det Bergenske Dampskibsselskab of Bergen in 1905. Irma sailed for the company until she was attacked and sunk by two MTBs belonging to the Royal Norwegian Navy on 13 February 1944.
SS Imo was a steamship that served in passenger and freight trades and later as a whaling supply ship. Christened SS Runic, she was bought, sold and renamed numerous times during her career. In 1917, Imo was under Norwegian registry chartered by the Belgian Relief Commission to bring supplies to war-ravaged Europe.
The 1943 Filipstad explosion was a fire in an ammunition store at Filipstad in Oslo on Sunday, 19 December 1943, during the occupation of Norway by Nazi Germany. The fire started during the unloading of ammunition from the transport ship Selma. The estimated amount of exploded ammunition varies from 800 to 1,200 tons. A large number of shells and grenades were tossed into the air and spread over the city. There were around 40 Norwegian casualties and around 75 Germans were killed, and 400 wounded. About 400 buildings were severely damaged.
Tirpitz was the second of two Bismarck-class battleships built for Nazi Germany's Kriegsmarine (navy) prior to and during the Second World War. Named after Grand Admiral Alfred von Tirpitz, the architect of the Kaiserliche Marine, the ship was laid down at the Kriegsmarinewerft Wilhelmshaven in November 1936 and her hull was launched two and a half years later. Work was completed in February 1941, when she was commissioned into the German fleet. Like her sister ship, Bismarck, Tirpitz was armed with a main battery of eight 38-centimetre (15 in) guns in four twin turrets. After a series of wartime modifications she was 2000 tonnes heavier than Bismarck, making her the heaviest battleship ever built by a European navy.
Blücher was the second of five Admiral Hipper-class heavy cruisers of Nazi Germany's Kriegsmarine, built after the rise of the Nazi Party and the repudiation of the Treaty of Versailles. Named for Gebhard Leberecht von Blücher, the Prussian victor of the Battle of Waterloo, the ship was laid down in August 1936 and launched in June 1937. She was completed in September 1939, shortly after the outbreak of World War II. After completing a series of sea trials and training exercises, the ship was pronounced ready for service with the fleet on 5 April 1940. She was armed with a main battery of eight 20.3 cm (8.0 in) guns and, although nominally under the 10,000-long-ton (10,000 t) limit set by the Anglo-German Naval Agreement, actually displaced over 16,000 long tons (16,000 t).
German submarine U-473 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.
SS Kommandøren was a steel-hulled passenger/cargo steamship built in Norway in 1891. She served as a communications link between the regional capital of Western Norway, Bergen, and the various communities of Sogn og Fjordane county.
The Harbour explosion occurred in Bergen, Norway on 20 April 1944.
Operation Guidance was an Australian-British raid during World War II in 1944.
German submarine U-1053 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.
