The Deutschland class was a series of three Panzerschiffe, a form of heavily armed cruiser, built by the Reichsmarine officially in accordance with restrictions imposed by the Treaty of Versailles. The ships of the class, Deutschland, Admiral Scheer, and Admiral Graf Spee, were all stated to displace 10,000 long tons (10,160 t) in accordance with the Treaty, though they actually displaced 10,600 to 12,340 long tons at standard displacement. The design for the ships incorporated several radical innovations, including the first major use of welding in a warship and all-diesel propulsion. Due to their heavy armament of six 28 cm (11 in) guns and lighter weight, the British began referring to the vessels as "pocket battleships". The Deutschland-class ships were initially classified as Panzerschiffe, but the Kriegsmarine reclassified them as heavy cruisers in February 1940.
The Courbet-class battleships were the first dreadnoughts built for the French Navy. These were completed prior to WWI. The class comprised four ships: Courbet, France, Jean Bart, and Paris. All four ships were deployed to the Mediterranean Sea for the entirety of World War I, spending most of their time escorting French troop convoys from North Africa and covering the Otranto Barrage. An Anglo-French fleet led by Courbet succeeded in sinking the Austro-Hungarian protected cruiser Zenta in the Battle of Antivari. Jean Bart was torpedoed in the bow by U-12 on 21 December 1914, but she was able to steam to Malta for repairs.
The Bourrasque class was a group of twelve French Navy destroyers (torpilleur) laid down in 1923 and in service from 1926 to 1950. Along with the heavier Chacal class, they were part of a plan to modernise the French fleet after the First World War. The Bourrasques were smaller and slower than the Chacals, but were nonetheless comparable with the British W class. The class saw varied service in the Second World War, in five different navies, on both sides. These ships were named after types of wind.
HNoMS Sleipner was a destroyer commissioned into the Royal Norwegian Navy in 1936. The lead ship of the Sleipner class, she gained near-legendary status in Norway by enduring over two weeks of intense air attack by Luftwaffe bombers following the 9 April 1940 invasion of Norway. After the resistance in South Norway started unravelling she made her way over the North Sea to continue the fight against the Germans from exile. After serving as a convoy escort along the coast of the United Kingdom, she was decommissioned in 1944. She was recommissioned in 1948 after being converted to a frigate. Along with her surviving sister ships she was sold for scrapping in 1959.
HMS Warwick (D25) was an Admiralty W-class destroyer built in 1917. She saw service in both the First and Second World Wars, before being torpedoed and sunk in February 1944.
Sibylle (Q175) was a Diane-class submarine of the French Navy commissioned in 1934. During World War II, she operated on the Allied side until 1940, when she became part of the naval forces of Vichy France. She disappeared during Operation Torch, the Allied invasion of French North Africa, in November 1942.
HNoMS Tor was a Sleipner-class destroyer of the Royal Norwegian Navy that was launched in September 1939. She was under outfitting and testing when Nazi Germany invaded Norway on 9 April 1940. Although scuttled by Norwegian naval personnel to prevent her from being captured by the invading forces, she was soon salvaged by the Germans and put into service with the Kriegsmarine. Under the name Tiger she served out the war as an escort and training vessel, being recovered by the Norwegians in Denmark after the German capitulation in 1945. After the war she was converted to a frigate and served until 1959.
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 in) guns and, although nominally under the 10,000-long-ton (10,160 t) limit set by the Anglo-German Naval Agreement, actually displaced over 16,000 long tons (16,260 t).
SS Nordnorge was a Norwegian steamship built in 1923–24 by Trondhjems mekaniske Værksted, for the Narvik-based Norwegian shipping company Ofotens Dampskibsselskap. First employed on the company's Narvik-Trondheim route, she was transferred to the longer Hurtigruten route in late 1936. Seized by the Germans following their April 1940 attack on Norway, she was used as covert troop ship and was sunk shortly after delivering her cargo of German troops behind Allied lines on 10 May 1940.
HMS Whitley (L23), ex-Whitby, was a W-class destroyer of the British Royal Navy that saw service in the British campaign in the Baltic Sea against Bolshevik forces during the Russian Civil War and in the early months of World War II.
Cyclone was a Bourrasque-class destroyer built for the French Navy during the 1920s. She saw service in the early months of World War II before being scuttled in June 1940 to prevent her capture by advancing German forces during the Battle of France.
The French destroyer Lansquenet was one of a dozen Le Hardi-class destroyers built for the French Navy during the late 1930s. Placed into service after the French signed an armistice with the Germans in June 1940, she sailed to French Morocco to avoid capture. In November the ship helped to escort one of the battleships damaged by the British during their July attack on Mers-el-Kébir, French Algeria, back to France. Placed in reserve afterwards, she was scuttled to prevent her capture when the Germans occupied Vichy France in November 1942. Lansquenet was salvaged in 1943 by the Regia Marina and captured by the Germans after the Italian armistice in September. They scuttled the ship in Italy in 1945; she was refloated in 1946, but was never repaired. She was stricken in 1958, then scrapped.
Siroco was one of a dozen Le Hardi-class destroyers built for the French Navy during the late 1930s under the name Le Corsaire. Although she was still under construction during the Battle of France, the ship sailed to French Algeria to avoid capture by the Germans. She was renamed Siroco in early 1941 while still under construction and was completed later that year and immediately placed in reserve. The destroyer was one of the ships scuttled to prevent their capture in November 1942 when the Germans occupied Vichy France. Siroco was salvaged by the Regia Marina and towed to Italy in 1943. Captured by the Germans after the Italian armistice in September, the ship was scuttled by the Germans in late 1944 and later scrapped.
