The Leopard was a German Raubtier-class torpedo boat. The Leopard was built as fifth out of six ships built for the German navy in 1920s. She was laid down on 4th May 1927 and commissioned on 15th April 1929. Her main armament as built was made up of three single 10.5 cm SK C/28 cannons and two triple 500 mm torpedo tubes. After modernisation in 1932, the ship received three 12.8 cm SK C/34 cannons as replacement for the older 10.5 cm ones. Anti-aircraft protection was also added in the form of two 2 cm C/38 autocannons. The 500 mm torpedo tubes were removed and replaced by two triple 533 mm launchers amidships. During Spanish Civil War, the ship made multiple non-intervention patrols. After the outbreak of WWII, she patrolled around the Skagerrak inspecting neutral shipping. She took part in invading Norway, landing troops in Bergen. On 30th April, after escorting minelayers from laying a minefield in the Skagerrak, Leopard was accidentally rammed by minesweeper Preussen, and sunk.

The Leopard was introduced in Update 1.79 "Project X" as part of the fleet closed beta test. As a starter ship, the Leopard possesses the highest calibre cannons of all starter destroyers, coupled with very high fire rate. However, it also comes with its own drawbacks, such as only 100 rounds per gun and unprotected magazines located on the waterline. The turrets are protected by 8 mm thick antifragmentation armour making them immune only to low calibre machine gun fire. The Leopard is also one of the faster destroyers with a max speed of 63 km/h, her torpedo armament is made up of the G7a torpedoes which have 358.4 kg TNT eq explosive yield and speed of 81 km/h with 6 km range, making them overall a very versatile weapon.
