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.
HMS Triumph, originally known as Libertad, was the second of the two Swiftsure-class pre-dreadnought battleships of the Royal Navy. The ship was ordered by the Chilean Navy, but she was purchased by the United Kingdom as part of ending the Argentine–Chilean naval arms race. Triumph was initially assigned to the Home Fleet and Channel Fleets before being transferred to the Mediterranean Fleet in 1909. The ship briefly rejoined the Home Fleet in 1912 before she was transferred abroad to the China Station in 1913. Triumph participated in the hunt for the German East Asia Squadron of Maximilian Graf von Spee and in the campaign against the German colony at Qingdao, China early in World War I. The ship was transferred to the Mediterranean in early 1915 to participate in the Dardanelles Campaign against the Ottoman Empire. She was torpedoed and sunk off Gaba Tepe by the German submarine U-21 on 25 May 1915.
HMS Majestic was a Majestic-class pre-dreadnought battleship of the Royal Navy. Commissioned in 1895, she was the largest pre-dreadnought launched at the time. She served with the Channel Fleet until 1904, following which she was assigned to the Atlantic Fleet. In 1907, she was part of the Home Fleet, firstly assigned to the Nore Division and then with the Devonport Division. From 1912, she was part of the 7th Battle Squadron.
USS L-10 (SS-50) was an L-class submarine of the United States Navy.
HMS E11 was an E-class submarine of the Royal Navy launched on 23 April 1914. E11 was one of the most successful submarines in action during the 1915 naval operations in the Dardanelles Campaign, sinking over 80 vessels of all sizes in three tours of the Sea of Marmara.
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.
HMS B11 was the last of 11 B-class submarines built for the Royal Navy in the first decade of the 20th century. Completed in 1906, it is best known for carrying out a successful attack on the Ottoman battleship Mesûdiye in the Dardanelles, an action for which her captain received the Victoria Cross. It spent the remainder of its active life serving in the Mediterranean, being converted into a surface patrol boat late in the war. B11 was sold for scrap in 1919.
HMS E3 was the third E-class submarine to be constructed, built at Barrow by Vickers in 1911–1912. Built with compartmentalisation and endurance not previously achievable, these were the best submarines in the Royal Navy at the start of the First World War. She was sunk in the first ever successful attack on one submarine by another, when she was torpedoed on 18 October 1914 by U-27 north of Schiermonnikoog, the Netherlands.

HMS H8 was a British H-class submarine built by the Canadian Vickers Co., Montreal. She was laid down on 19 May 1915 and commissioned in June 1915. Like other Canadian-built submarines, she was sailed across the Atlantic for service in the North Sea and as recognition of this she initially remained under the command of her Canadian captain, Lieutenant-Commander B. L. Johnson, R.N.R. with a largely reserve crew. HMS H8 was sold on 29 November 1921 in Arbroath.
HMS L2 was a L-class submarine built for the Royal Navy during World War I.

HMS E24 was an E-class submarine of the Royal Navy built by Vickers, Barrow-in-Furness. She was launched on 9 December 1915 and was commissioned on 9 January 1916. E24 was a mine-laying submarine.
HMS E14 was a British E class submarine built by Vickers, Barrow-in-Furness. During the First World War, two of her captains were awarded the Victoria Cross, and many of her officers and men also decorated. HMS E14 was laid down on 14 December 1912 and was commissioned on 18 November 1914. Her hull cost £105,700. She was sunk by shellfire from coastal batteries in the Dardanelles on 28 January 1918.

The French submarine Mariotte was a submarine built for the French Navy prior to World War I. Intended to accompany the fleet, she was designed for high speed on the surface. Although the navy was unsatisfied with her performance on the surface, the boat had a higher underwater speed than any French submarine before or during the following 35 years. Mariotte was plagued with engine problems during her construction and the navy spent years fixing the various issues before finally commissioning her five years after beginning construction. During the war, she participated in the Dardanelles Campaign, but had to be scuttled after she became entangled in the cables of a minefield on her first attempt to penetrate the Dardanelles.
