Jaguar was the sixth and last Type 24 torpedo boat built for the German Navy (initially called the Reichsmarine and then renamed as the Kriegsmarine in 1935) during the 1920s.

Jaguar spent the next several months escorting minelayers as they laid minefields and damaged heavy ships back to Germany before she was transferred to France around September.

She helped to escort blockade runners, commerce raiders and submarines through the Channel and the Bay of Biscay, as well as Norwegian waters, for the next several years.

[4] As built, the Type 24s mounted three 10.5 cm (4.1 in) SK C/28[Note 1] guns, one forward and two aft of the superstructure, numbered one through three from bow to stern.

[10] During the Norwegian Campaign, Jaguar and Falke, among other ships, briefly rendered assistance to the torpedoed heavy cruiser Lützow before continuing onwards to Kristiansand on 11 April with reinforcements.

[11] On 4–5 June Falke and Jaguar provided the anti-submarine screen from Kiel, Germany, to the Skaggerak for an unsuccessful attempt to intercept the Allied convoys evacuating Northern Norway by the battleships Gneisenau and Scharnhorst and the heavy cruiser Admiral Hipper.

The flotilla joined the escort force for Scharnhorst, Gneisenau and the heavy cruiser Prinz Eugen on 12 February off Cap Gris-Nez during the Channel Dash.

In September and October, Jaguar was one of the escorts for German blockade runners sailing from ports in the Bay of Biscay en route to Japan.

On 3–7 May, Jaguar, Greif, the torpedo boat Möwe escorted minelayers in the North Sea as they laid new minefields.

Despite the expenditure of over 50 torpedoes and large quantities of ammunition, they were generally unsuccessful, only sinking the destroyer HNoMS Svenner on 6 June.
