Russian Narval-class submarine
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. The Narval class had advanced features including watertight bulkheads, a crash diving tank and gravitationally filled ballast tanks which did not feature in contemporary Russian-designed boats. The boats were well regarded by the Russian Navy and served in the Black Sea Fleet during World War I, during which they sank 8 merchant ships and 74 coastal vessels.

The 75 mm 50 caliber Pattern 1892 was a Russian naval gun developed in the years before the Russo-Japanese War that armed the majority of warships of the Imperial Russian Navy during the Russo-Japanese War and World War I. The majority of ships built or refit between 1890 and 1922 carried Pattern 1892 guns. During its career the role of the guns evolved from one of anti-torpedo boat defense to coastal artillery and anti-aircraft use.
