HMAS AE2 was an E-class submarine of the Royal Australian Navy (RAN). One of two submarines ordered for the fledgling navy, AE2 was built by Vickers Armstrong in England and was commissioned into the RAN in 1914. Together with her sister submarine, HMAS AE1, the boat then sailed to Australia in what was, at the time, the longest voyage ever undertaken by a submarine.
The C class was a group of twenty-eight light cruisers of the Royal Navy, and were built in a sequence of seven groups known as the Caroline class, the Calliope class, the Cambrian class, the Centaur class, the Caledon class, the Ceres class and the Carlisle class. They were built for the rough conditions of the North Sea, and proved to be rugged and capable vessels, despite being somewhat small and cramped.
The B class was a class of 11 submarines, built by Vickers in Barrow-in-Furness for the Royal Navy, and launched in 1904–06. One boat was sunk by a collision in 1912, but the remainder served in World War I. Three boats protected the transfer of the British Expeditionary Force to France in 1914, but were soon relegated to local defence and training duties. Six submarines were in the Mediterranean when the war began and were quickly sent to the Dardanelles to prevent a breakout by the German battlecruiser SMS Goeben and the light cruiser SMS Breslau into the Eastern Mediterranean. B11 ventured into the Dardanelles in December 1914 and sank the elderly Turkish ironclad Mesudiye.
Naval warfare in World War I was mainly characterised by blockade. The Allied Powers, with their larger fleets and surrounding position, largely succeeded in their blockade of Germany and the other Central Powers, whilst the efforts of the Central Powers to break that blockade, or to establish an effective counter blockade with submarines and commerce raiders, were eventually unsuccessful. Major fleet actions were extremely rare and proved less decisive.
The Type UB I submarine was a class of small coastal submarines (U-boats) built in Germany at the beginning of the First World War. 20 boats were constructed, most of which went into service with the German Imperial Navy. Boats of this design were also operated by the Austro-Hungarian Navy and the Bulgarian Navy. In the Austro-Hungarian Navy, it was called the U-10 class.
A naval race had developed in the Aegean after the end of the Balkan Wars, with the Ottoman government ordering several ships, including two dreadnoughts, in Britain. In the event, with the outbreak of World War I, one of these ships, including further two scout cruisers and four destroyers, were confiscated and pressed into service with the Royal Navy. This disappointed the Ottomans, contributing to their joining the Central Powers in the Great War.
A British submarine flotilla operated in the Baltic Sea for three years during the First World War. The squadron of nine submarines was attached to the Russian Baltic Fleet. The main task of the flotilla was to prevent the import of iron ore from Sweden to Imperial Germany. The success of the flotilla also forced the German Navy in the Baltic to keep to their bases and denied the German High Seas Fleet a training ground. The flotilla was based in Reval (Tallinn), and for most of its career commanded by Captain Francis Cromie.
SMS Prinz Adalbert was an armored cruiser built in the early 1900s for the Imperial German Navy. She was named after Prince Adalbert of Prussia, former Commander-in-Chief of the Prussian Navy, and was the lead ship of her class.
The Mediterranean U-boat Campaign in the Mediterranean Sea was fought by Austria-Hungary and German Empire against the Allies during World War I. It was characterised by the ability of the Central Powers to raid with near impunity during the first years of the war, causing substantial shipping losses, until the introduction of the convoy system allowed the Allies to drastically cut their losses from 1917 on.
SM UB-16 was a German Type UB I submarine or U-boat in the German Imperial Navy during World War I. The submarine was sunk by a British submarine in May 1918.
The U-boat campaign from 1914 to 1918 was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. The German Empire relied on imports for food and domestic food production and the United Kingdom relied heavily on imports to feed its population, and both required raw materials to supply their war industry; the powers aimed, therefore, to blockade one another. The British had the Royal Navy which was superior in numbers and could operate on most of the world's oceans because of the British Empire, whereas the Imperial German Navy surface fleet was mainly restricted to the German Bight, and used commerce raiders and unrestricted submarine warfare to operate elsewhere.
An armed boarding steamer was a merchantman that the British Royal Navy converted to a warship during the First World War. AB steamers or vessels had the role of enforcing wartime blockades by intercepting and boarding foreign vessels. The boarding party would inspect the foreign ship to determine whether to detain the ship and send it into port or permit it to go on its way.
HMS Manly was a Yarrow M-class destroyer of the British Royal Navy. Built by the Scottish shipbuilder Yarrow between 1913 and 1914, Manly served during the First World War. She formed part of the Harwich Force in the early years of the war, and then later in the English Channel as part of the Dover Patrol taking part in the Zeebrugge Raid in 1918. She survived the war, and was sold for scrap in 1920.
HMS Lark was a Laforey-class destroyer of the British Royal Navy. The Laforey class was the class of destroyers ordered under the Royal Navy's 1912–1913 construction programme, which were armed with three 4-inch (102 mm) guns and four torpedo tubes and were capable of 29 knots. The ship, which was originally to be named Haughty but was renamed before launch, was built by the Scottish shipbuilder Yarrow between 1912 and 1913.
SMS S32 was a V25-class large torpedo boat of the Imperial German Navy that served during the First World War. She was built by the Schichau-Werke shipyard in Elbing, East Prussia, being launched on 28 February 1914 and was completed in September that year.
SMS V26 was a V25-class torpedo boat of the Imperial German Navy that served during the First World War. The ship was built by AG Vulcan at Stettin in Prussia, and was completed in June 1914.
Intibah was a ship used by the Ottoman Navy as a tugboat and minelayer in World War I.
