Derived from the World War I-era large torpedo boat, the Type 23 torpedo boat was slightly larger, but had a similar armament and speed.[1] The Type 23 had an overall length of 87.7m (287.7feet) and was 85.7m (281.2feet) long at the waterline. The ships had a beam of 8.25m (27.07feet), and a mean draft of 3.650NaN0. They displaced 923LT at standard load and 1290LT at deep load.[2] Kondor was fitted with a pair of Schichau geared steam turbine sets, each driving one propeller, that were designed to produce 23000shp using steam from three water-tube boilers which would propel the ship at 33kn.[3] The torpedo boats carried enough fuel oil to give them an intended range of 3600nmi at,[1] but it proved to be only 1800nmi at that speed in service. Their crew consisted of 4 officers and 116 sailors.[2]
As built, the Type 23s mounted three 10.5sp=usNaNsp=us SK L/45 guns, one forward and two aft of the superstructure; the aft superfiring gun was on an open mount while the others were protected by gun shields.[4] They carried six above-water 50 cm (19.6 in) torpedo tubes in two triple mounts[5] and could also carry up to 30 mines. After 1931, the torpedo tubes were replaced by 533mm tubes[1] and a pair of 2adj=on1adj=on 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 and another pair were mounted on the bridge wings, all in single mounts. Around 1944 a FuMB 4 Sumatra radar detector was installed as was radar.[6]
Named after the Condor, the boat was laid down at the Reichsmarinewerft Wilhelmshaven (Navy Yard) on 17 November 1925[3] as yard number 106,[7] launched on 22 September 1926 and commissioned on 15 July 1928.[3] The boat was initially assigned to the 4th Torpedo Boat Half Flotilla. By the end of 1936 Kondor was assigned to the 4th Torpedo Boat Flotilla and the boat made several deployments to Spain during the Spanish Civil War.[8]
Now assigned to the 5th Torpedo Boat Flotilla, Kondor supported the North Sea mining operations that began on 3 September 1939.[9] During the Norwegian Campaign, the boat was assigned to Group 5 under Konteradmiral Oskar Kummetz on the heavy cruiser, tasked to capture Oslo. Kondor transported about 100 men of the invasion force and was one of the cruiser's escorts through the Baltic and Kattegat. At 02:30 the small motor minesweepers R17 and R21 and Kondor were detached to occupy the naval base at Karljohansvern, in the town of Horten. Her sister ship,, had become separated from the main body while crippling the Norwegian patrol boat earlier that night and followed Kondors group to Horten.[10]
See main article: Battle of Horten Harbour. The German force tasked to occupy Karljohansvern was scheduled to do so at dawn on 9 April, but Kondors captain, Kapitänleutnant (Lieutenant) Hans Wilck, commander of the force, decided to assault the harbor directly since the Norwegians had already been alerted. About 140 soldiers were transferred to R17 and R21 and the former ship was in the lead as they steamed through the harbor entrance at 04:35 at high speed, slowly followed by Albatros, while Kondor was transferring her embarked troops to another ship. The minelayer engaged R17 ten minutes later and set her on fire, but not before she unloaded her troops. The minelayer was only able to get a few shots off at R21 before she steamed behind an island in the harbor. About this time, Albatros was approaching the harbor mouth and exchanged fire with Olav Tryggvason without effect. The torpedo boat, with only a single gun able to bear on the minelayer, withdrew behind one of the outer islands and started blindly bombarding the harbor. Albatros withdrew not long after she was hit by a shell around 06:30 and the German troops that had made it ashore bluffed the Norwegians into surrendering at 07:35, but not before Wilck had reloaded his troops and sailed to regain radio communication with the German cruisers to support the attack.[11]
Later that morning, Kondor and Albatros were ordered to land their troops at Son and then Kondor and several minesweepers were able to pass through the Drøbak Sound after the Norwegian coastal defenses had sunk Blücher while passing through the Sound further up the Oslofjord, and search for Blüchers survivors. During the search, she damaged a propeller on Blüchers wreckage. Later that day, Kondor supported German forces as they occupied Drøbak. The following morning, Albatros and Kondor were engaged by coastal batteries on the island of Bolærne and forced to turn away. After the coast-defense guns broke down, Kondors crew occupied the island. After the heavy cruiser had been crippled by a British submarine off the Danish coast on 11 April, Kondor and her sister, among other ships, arrived later that morning to render assistance.[12]
Escorted by two destroyers, Kondor, Möwe, and the torpedo boat, minelayers laid a minefield in the Skaggerak on 29–30 April. En route, the torpedo boat was sunk when she was accidentally rammed by the minelayer Preussen. From 20–23 June, Kondor was one of the escorts for the badly damaged battleship from Norway to Kiel, Germany. The following month, she helped to escort Scharnhorsts sister, from Trondheim, Norway, to Kiel from 25–28 July. Now assigned to the 5th Torpedo Boat Flotilla, Kondor, her sister, and the torpedo boats,, and escorted minelayers as they laid a minefield in the southwestern North Sea on 7/8 August. The flotilla escorted another minelaying mission in the same area on 14–15 August. The following month, Kondor was transferred to the 1st Torpedo Boat Flotilla, with, T2, and . On 6–7 September they escorted a minelaying mission in the English Channel. Rejoining the 5th Flotilla before the end of the month, Kondor and her sisters, Falke,, and laid a minefield in the English Channel on 30 September – 1 October. Reinforced by Wolf and Jaguar, the flotilla made an unsuccessful sortie off the Isle of Wight on 8–9 October. They made a second, more successful, sortie on 11–12 October, sinking two Free French submarine chasers and two British trawlers. The 5th Flotilla was transferred to St. Nazaire later that month and its ships laid a minefield off Dover on 3–4 December.[13]
Kondor was refitted in Rotterdam, Netherlands, from March to May 1941. She was transferred afterwards to the Skagerrak where she was on convoy escort duties. The boat was again refitted in Rotterdam from November to December.[14]
The flotilla joined the escort force for Gneisenau, Scharnhorst and the heavy cruiser on 12 February 1942 off Cap Gris-Nez during the Channel Dash. From 12 March to 2 April, the flotilla escorted the commerce raider through the English Channel despite heavy British attacks, damaging the British destroyers and . The flotilla escorted the commerce raider through the English Channel from 12 to 19 May. In heavy fighting on the 13th, British motor torpedo boats (MTBs) sank Seeadler and the torpedo boat while losing one of their own boats. Falke and Kondor and the torpedo boats and escorted the Italian blockade runner,, from Bordeaux through the Bay of Biscay on 29–30 November. Another Italian blockade runner, Himalaya, escorted by Kondor and the torpedo boats T2,, T22, and T23, failed in her attempt to break through the Bay of Biscay when she was spotted by British aircraft and forced to return by heavy aerial attacks on 9–11 April. Kondor, Greif, Falke, Möwe and T22 laid two minefields in the English Channel on 4–6 June. Later that month the ships returned to the Bay of Biscay to help escort U-boats through the Bay and continued to do so into early August. Möwe and Kondor helped to lay two minefields in the English Channel on 3–5 September. Kondor, Greif and the torpedo boats,, and followed this with another minefield in the English Channel on 29–30 September.[15]
The 4th and 5th Torpedo Boat Flotillas, consisting Kondor, Greif, Möwe, and the torpedo boats,, and laid minefields of 180 mines, off Le Havre and Fécamp, France, on 21 and 22 March. On 17–19 April 1944, the 5th Torpedo Boat Flotilla, including Kondor, Greif and Möwe, sailed from Brest, France, to Cherbourg as distant cover for a convoy. A few days later, the flotilla laid a minefield on the night of 21/22 April. The following night the torpedo boats engaged British MTBs near Cape Barfleur and sank one of them. On the nights of 26/27 and 27/28 April, they laid 108 mines each night near Cherbourg. While trying to evade British aerial attacks on the latter night, Kondor struck a British mine, but was only lightly damaged. On 30 April and 1 May, the flotilla laid 260 mines in three minefields. Three weeks later, the flotilla was ordered to transfer from Cherbourg to Le Havre and departed on the night of 23/24 May. Kondor, Greif, Falke, Möwe and Jaguar were attacked by Allied aircraft early the next day and Greif was struck by two bombs that set her forward boiler room on fire and caused her to take on water forward. With both boiler rooms subsequently flooded, she was unmaneuverable and accidentally collided with Falke. The latter was only slightly damaged, but Greifs bow was badly bent, which caused problems for Möwe when she began to tow her sister. Around 06:00 Greif lost all power and sank a half hour later. At 07:43 Kondor struck a mine and had to be towed by Möwe for the remainder of the voyage. Kondor began a lengthy refit in Le Havre, but was cannibalized for spare parts after the Allies landed in Normandy on 6 June. The boat was decommissioned on 28 June and was then declared a total loss after being hit by bombs on 31 July or 2 August.[16]
