The Kriegsmarine was the navy of Nazi Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945.
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943.
German submarine U-862 was a Type IXD2 U-boat of Nazi Germany's Kriegsmarine during World War II. After Germany's surrender in May 1945, U-862 put into Singapore and was taken over by the Imperial Japanese Navy under the name I-502.
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures.
I-25 (イ-25) was a B1 type (I-15-class) submarine of the Imperial Japanese Navy that served in World War II, took part in the Attack on Pearl Harbor, and was the only Axis submarine to carry out aerial bombing on the continental United States in World War II, during the so-called Lookout Air Raids, and the shelling of Fort Stevens, both attacks occurring in the state of Oregon.
Commerce raiding is a form of naval warfare used to destroy or disrupt logistics of the enemy on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them.
HMAS Perth was one of three modified Leander-class light cruisers used by the Royal Australian Navy (RAN) during the early part of World War II. She was built for the Royal Navy (RN) in the mid-1930s and was commissioned as HMS Amphion in 1936. The ship spent the next several years as flagship of the Commander-in-Chief, Africa before she was transferred to the RAN in 1939 and renamed as HMAS Perth.
HMAS Arunta (I30/D5/D130) was a Tribal-class destroyer of the Royal Australian Navy (RAN). Named for the Arrernte Aboriginal peoples, the destroyer was laid down in 1939 and commissioned into the RAN in 1942.
There was considerable Axis naval activity in Australian waters during the Second World War, despite Australia being remote from the main battlefronts. German and Japanese warships and submarines entered Australian waters between 1940 and 1945 and attacked ships, ports and other targets. Among the best-known attacks are the sinking of HMAS Sydney by a German raider in November 1941, the bombing of Darwin by Japanese naval aircraft in February 1942, and the Japanese midget submarine attack on Sydney Harbour in May 1942. About 40 Allied merchant ships were damaged or sunk off the Australian coast by surface raiders, submarines and mines. Japanese submarines also shelled three Australian ports and submarine-based aircraft flew over several Australian capital cities.
HMAS Kuttabul, formerly SS Kuttabul, was a Royal Australian Navy depot ship, converted from a Sydney Ferries Limited ferry.
From 31 May to 8 June 1942, during World War II, Imperial Japanese Navy submarines made a series of attacks on the Australian cities of Sydney and Newcastle. On the night of 31 May – 1 June, three Ko-hyoteki-class midget submarines, each with a two-member crew, entered Sydney Harbour, avoided the partially constructed Sydney Harbour anti-submarine boom net, and attempted to sink Allied warships. Two of the midget submarines were detected and attacked before they could engage any Allied vessels. The crew of M-14 scuttled their submarine, whilst M-21 was successfully attacked and sunk. The crew of M-21 killed themselves. These submarines were later recovered by the Allies. The third submarine attempted to torpedo the heavy cruiser USS Chicago, but instead sank the converted ferry HMAS Kuttabul, killing 21 sailors. This midget submarine's fate was unknown until 2006, when amateur scuba divers discovered the wreck off Sydney's northern beaches.
The history of the Royal Australian Navy traces the development of the Royal Australian Navy (RAN) from the colonisation of Australia by the British in 1788. Until 1859, vessels of the Royal Navy made frequent trips to the new colonies. In 1859, the Australia Squadron was formed as a separate squadron and remained in Australia until 1913. Until Federation, five of the six Australian colonies operated their own colonial naval force, which formed on 1 March 1901 the Australian Navy's (AN) Commonwealth Naval Force which received Royal patronage in July 1911 and was from that time referred to as Royal Australian Navy (RAN). On 4 October 1913 the new replacement fleet for the foundation fleet of 1901 steamed through Sydney Heads for the first time.
During World War II, surface raiders and submarines of the Axis powers, primarily Germany and Japan, conducted naval activities in various parts of the world, including the waters around New Zealand.
HMAS Geelong (J201), named for the city of Geelong, Victoria, was one of 60 Bathurst-class corvettes constructed during World War II, and one of 36 initially manned and commissioned solely by the Royal Australian Navy (RAN).
The Shelling of Newcastle was conducted by the Japanese submarine I-21 in the early hours of 8 June 1942. The bombardment followed the attack on Sydney Harbour on 31 May, and was conducted shortly after I-24 shelled the Eastern Suburbs of Sydney. During the attack I-21 fired 34 shells at Newcastle, including eight illumination rounds, but caused little damage. The Australian gunners at Fort Scratchley fired four shells at the submarine, but scored no hits.
I-17 was a Japanese B1 type submarine of the Imperial Japanese Navy which saw service during World War II. This long-range submarine cruiser spent the early months of the war in the eastern Pacific and was the first Axis ship to shell the continental United States. She later supported the Imperial Japanese Army in fighting around the Solomon Islands and remained active in the southwest Pacific until she was sunk in August 1943.
Allied submarines were used extensively during the Pacific War and were a key contributor to the defeat of the Empire of Japan.
Prior to World War II, the Indian Ocean was an important maritime trade route between European nations and their colonial territories in East Africa, the Arabian Peninsula, British India, Indochina, the East Indies (Indonesia), and Australia for a long time. Naval presence was dominated by the Royal Navy Eastern Fleet and the Royal Australian Navy as World War II began, with a major portion of the Royal Netherlands Navy operating in the Dutch East Indies and the Red Sea Flotilla of the Italian Regia Marina operating from Massawa.
Convoy GP55 was a convoy of Allied ships that travelled from Sydney to Brisbane in June 1943 during World War II. It comprised ten cargo ships, three landing ships, tank (LSTs) and an escort of five corvettes. The Japanese submarine I-174 attacked the convoy on 16 June, sinking the United States Army transport ship Portmar and damaging USS LST-469. Two of the corvettes counter-attacked I-174, but only lightly damaged her.
At the start of World War II, the Royal Navy was the strongest navy in the world, with the largest number of warships built and with naval bases across the globe. It had over 15 battleships and battlecruisers, 7 aircraft carriers, 66 cruisers, 164 destroyers and 66 submarines. With a massive merchant navy, about a third of the world total, it also dominated shipping. The Royal Navy fought in every theatre from the Atlantic, Mediterranean, freezing Northern routes to Russia and the Pacific Ocean.
