Background

The class was constructed as part of an ambitious programme of naval construction devised by the Naval General Staff in 1909. This envisaged, among other things, the constructions of six submarines for the Black Sea Fleet. The procurement was heavily cut back and delayed; in 1910, the Russian State Duma

The Narval class were a group of submarines built for the Imperial Russian Navy. They were designed by the Electric Boat Company and ordered in the 1911 programme as the "Holland 31A" design.

s were ordered along with three of the new Morzh-class boats. The Narval class was a design developed by the Holland company for Russia.

Design

The design of the Morzh class was based on the Akula
Russian submarine Akula (1908)
Akula was a submarine built for the Imperial Russian Navy. The boat was designed by Ivan Bubnov and was an amalgam of the previous Minoga and the Kasatka class submarine designs. The design was presented to the Marine technical committee in late 1905. Initially the boat was to use petrol engines...

 under Ivan Grigorevich Bubnov in 1910 and was approved on 30 May 1911, with construction starting at the Nikolayev shipyards on 25 June 1911. The principal objective of the designers was to deliver a high degree of maneuverability and stability. However, aspects of the design provoked controversy, in particular the lack of internal watertight compartments. This issue caused a heated dispute between Russia's submarine engineers and submarine officers; the engineers argued that adding bulkhead

s would greatly improve the survivability of the vessels while the submariners argued that bulkheads put the commander of the ship at risk of losing control of his crew. In the end, financial constraints required the bulkheads to be omitted.

The Morzh submarines were well-armed for the time, having a deck gun, four internal torpedo tubes and eight Dzhevetskiy torpedo-launching collars. However, the vessels had numerous shortcomings. They suffered from having only a single hull, lacking bulkheads, having a slow diving time of 3½ minutes due to poor ballast tank venting, and a diving depth of only 25 fathoms (50 m / 150 feet). An additional problem was that twin 1,140-horsepower diesel engines to power the vessels had been ordered from Germany

, but were not delivered by the time the war broke out. They had to be replaced by severely underpowered engines from the Amur River gunboats Vikhr, Vyuga and Uragan, each of which delivered only 250 horsepower. This meant that the designed 16 knot surface speed could not be attained. The designed 12 knot underwater speed also could not be attained due to a poorly designed hull shape, which was more like that of a surface vessel than a submarine. Many of these failings were replicated in the more numerous Bars class submarine

 in November 1915 but suffered damage in a Turkish air attack in May 1916. She was sunk with all hands in May 1917 on her 24th patrol, most likely as a result of striking a mine or coming under aerial attack. After 24 patrols the Nerpa went into refit in 1917 in Nikolayev but had to be laid up due to a shortage of essential parts and did not rejoin the war effort. The most successful of the three submarines was the Tyulen, which made a large number of successful attacks against enemy forces, including the capture of the armed merchantman Rodosto in October 1916.

The Tyulen and Nerpa survived the war but had very different fates. The Tyulen was captured by German troops at Sevastopol in May 1918 and transferred to British
