Derived from the preceding Type 23 torpedo boat, the Type 24 was slightly larger and faster, but had a similar armament.[1] The boats had an overall length of 92.6m (303.8feet) and were 89sp=usNaNsp=us long at the waterline. They had a beam of 8.65m (28.38feet), and a mean draft of 3.52m (11.55feet). The Type 24s displaced 932LT at standard load and 1319LT at deep load. Wolfs pair of Brown-Boveri geared steam turbine sets, each driving one propeller, were designed to produce 23000PS using steam from three water-tube boilers which would propel the ship at 34kn.[2] The boats carried enough fuel oil to give them a range of 1997nmi at . Their crew numbered 129 officers and sailors.[3]
As built, the Type 24s mounted three SK C/28 guns, one forward and two aft of the superstructure, numbered one through three from bow to stern. They carried six above-water 50 cm (19.7 in) torpedo tubes in two triple mounts amidships[4] and could also carry up to 30 mines. After 1931, the torpedo tubes were replaced by tubes[1] and a pair of C/30 anti-aircraft guns were added. During the war a quadruple 2 cm mount was added just forward of No. 2 gun, three 2 cm guns were positioned around the aft funnel, another pair were mounted on the bridge wings, and a gun was added in front of the bridge, all in single mounts. Around 1944 a FuMB 4 Sumatra radar detector was installed as was radar.[5]
Jaguar was laid down at the Reichsmarinewerft Wilhelmshaven (Navy Yard) on 4 May 1927[2] as yard number 113,[6] launched on 15 March 1928 and commissioned on 15 August 1929.[2] The boat was initially assigned to the 3rd Torpedo Boat Half-Flotilla and by the end of 1936 she was assigned to the 3rd Torpedo Boat Flotilla. She made several deployments to Spain during the Spanish Civil War.[7]
Together with the torpedo boat, Jaguar impounded six ships in the Skaggerak during an anti-contraband patrol in 14–16 December.[8] She began a refit later that month at Wesermünde that lasted until March 1940.[9] During the Norwegian Campaign, Jaguar and Falke, among other ships, briefly rendered assistance to the torpedoed heavy cruiser before continuing onwards to Kristiansand on 11 April with reinforcements.[10] 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 and and the heavy cruiser . From 21–23 June, Jaguar was one of the escorts for the badly damaged Scharnhorst from Norway to Kiel. Now assigned to the 5th Torpedo Boat Flotilla, Jaguar, and the torpedo boats, Falke,, and escorted minelayers as they laid a minefield in the southwestern North Sea on 7–8 August. The flotilla escorted other minelaying missions in the same area on 14–15 August, 31 August – 2 September and 6–7 September. Reinforced by her sister, the flotilla made an unsuccessful sortie off the Isle of Wight on 8–9 October. Jaguar and her sister laid a minefield off Dover on 29–30 October and then again on 2–3 December.[11]
Jaguar and Iltis laid a minefield off Eastbourne on 25–26 February and then again on 5–6 March. The pair escorted Scharnhorst and Gneisenau into Brest, France on 22 March after their North Atlantic raid. Jaguar began a refit the following month in Rotterdam, Netherlands, that lasted until May. She was transferred afterwards to the Skagerrak where she was on convoy escort duties until October. The ship rejoined the 5th Flotilla in France by February 1942. The flotilla joined the escort force for Scharnhorst, Gneisenau and the heavy cruiser on 12 February off Cap Gris-Nez during the Channel Dash. From 12 March to 2 April, the flotilla escorted the commerce raider through the Channel despite heavy British attacks, damaging the British destroyers and . 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.[12]
On 11 March 1943, Jaguar and the torpedo boat were among the escorts for the battleships and Scharnhorst as they moved from Trondheim, Norway, to Bogen Bay, and continued onward to Altafjord with Lützow and the light cruiser from 22 to 24 March. Jaguar, Greif, and the destroyer screened Nürnberg from Harstad to Trondheim and then to Kiel between 27 April and 3 May. On 3–7 May, Jaguar, Greif, the torpedo boat escorted minelayers in the North Sea as they laid new minefields. In June the boats returned to the Bay of Biscay to help escort U-boats through the Bay and continued to do so into early August.[13]
The 4th and 5th Torpedo Boat Flotillas, consisting Jaguar, Möwe, Greif, Kondor, and the torpedo boats and laid minefields off Le Havre and Fécamp, France, on 21 and 22 March 1944. The flotilla was ordered to transfer from Cherbourg to Le Havre and departed on the night of 23/24 May. Jaguar, Greif, Falke, Kondor and Möwe were attacked by Allied aircraft early the next day and Greif was struck by two bombs and later sank. As the Allies began landing in Normandy on 6 June, the 5th Flotilla, now consisting of Jaguar, Falke, Möwe and, sortied multiple times from Le Havre over the next week in attempts to sink Allied shipping. Despite the expenditure of over 50 torpedoes and large quantities of ammunition, they were generally unsuccessful, only sinking the destroyer on 6 June. During an air raid by heavy bombers of RAF Bomber Command on the night of 14/15 June against the harbour and the German warships there, Jaguar and Falke were sunk by bombs.[14]
