Nicknamed "ato" by German crews (i.e. atem- or air-torpedo, indicating the steam propulsion) to distinguish it from the G7e (electric torpedoes). 44 kn speed was only used for S-Boote. According to certain sources only used from surface vessels during the last part of World War II.TI Fat IG7aWet heater533.4 mm / 7163 mm120hm (30 kn) / 75 hm (40 kn) / 50 hm (44 kn)Ka (Pi1), Kc (Pi3)Standard TI with Fat program-control type I (for security-reasons only used by night).TI Lut IG7aWet heater533.4 mm / 7163 mm120 hm (30 kn) / 75 hm (40 kn) / 50 hm (44 kn)Ka (Pi1), Kc (Pi3)Standard TI with Lut program-control type I.TI Lut IIG7aWet heater533.4 mm / 7163 mm120hm (30kn) / 75 hm (40 kn) / 50 hm (44 kn)Ka (Pi1), Kc (Pi3)Standard TI with Lut program-control type II.TIüG7aWet heater533.4 mm / 7163 mm<120 hm (30 kn) / <75 hm (40 kn)Exercise head only (light)Torpedo dedicated for educational/training purposes with Schulboote at U-Flotillen. It had restricted settings on depth mechanism, a light (empty) exercise head and other minor modifications, to ensure positive buoyancy at the end of the run and reduced stress on the engine (=less damages and loss of torpedoes, i.e. achieving a higher number of shots).TIü Lut IIG7aWet heater533.4 mm / 7163 mm<120 hm (30 kn) / <75hm (40 kn)Exercise head only (light)TIü with Lut program-control type II.TIIG7eElectric, lead-acid battery (13T)533.4mm / 7163mm50 hm (30 kn)Ka (Pi1)Faulty pistols. Nicknamed "eto" (electric torpedo) by German crews for easy distinguishing from the G7a ("ato" air-driven torpedo). Could not be fitted with Fat or Lut due to its short range.TIIIG7eElectric, lead-acid (13T battery)534,6 mm / 7163 mm50 hm (30 kn)Kb (Pi2)Improved pistols and batteries (cable-guide from the battery-chamber to the warhead for powering magnetic pistols).

Only operational for a brief period before being replaced by the improved TV.TVG7esZaunkönigElectric, lead-acid534,6 mm / 7163 mm57 hm (24 kn)Ke1 (Pi4c)Acoustic homing (three different type of seekers). Nicknamed "GNAT" by the allies (acronym from "German Naval Acoustic Torpedo). Generally regarded as the best German torpedo of World War II (between 5000 and 6000 launched, with a reported hit-rate of approximately 53%, a number that was considerably reduced after post-war analysis). TV torpedoes were modified to TXI from fall 1944.TVaG7esZaunkönigElectric, lead-acid534,6mm / 7163 mm80 hm (21.5 kn)Ke1 (Pi4d)TV specially adapted for use on S-Boote (end-of-run detonation, reduced speed, longer range and different depth-mechanism).TVbG7esZaunkönigElectric, lead-acid534.6 mm / 7163 mm80 hm (21,5 kn)Ke1 (Pi4c)TVa adapted for use as an anti U-boat torpedo.TVIG7esElectric, lead-acid534,6 mm / 7163 mm75 hm (30 kn)Kf (Pi6)TIIIa with minor changes (probably with Lut II) and a special warhead which was never fielded.TVIIG7utSteinbuttWalter turbine534,6 mm / ? mm80 hm (45 kn)Kb (Pi2), Kf (Pi6)Ingolin (peroxide)/dekalin/helman/water fueled BO VI-turbine. Combustion-chamber arranged horizontally in the longitudinal axis. Approximately 100 torpedoes produced, but never fielded - mainly due to several problems with both pistol and start ballistics.TVIIIG7utSteinbarschWalter turbine534.6mm / ?mm80hm (45kn)Kb (Pi2), Kf (Pi6)Development of the TVII, with different internal organisation of the various mechanisms. More than 100 torpedoes produced. Was due to be fielded in April 1945, despite several problems during testing.TIXG5utGoldbuttWalter turbine534.6 mm / 5490 mm40 hm (45 kn)"Goldfisch"-variant planned for the German "Kleinst-Uboote". As development of the U-boat ended, so did the program for the TIX.TXG7ef NYKSpinneElectric, lead-acid (13T battery)534.6 mm / 7163 mm50hm (30 kn)Ka (Pi1)Developed from the TII torpedo. Wire guided by means of visual sight from a command bunker / observation site. Intended for coastal defence and use from beach-batteries (wagenbatterie), later evolved to also include special harbour installations (molenbatterie) and mobile launchers (schiffbatterie). Only 200 torpedoes were built (gerät 43d), originally for 35 "spinne sperrbatterie" to be established on the French channel- and Mediterranean coastline from July 1944. Some batteries were also established in Belgium, and after the allied invasion in July 1944 most of the French batteries were moved to the Netherlands, Germany and Denmark (85 TX torpedoes were located in 14 Danish batteries after the war).TXaG7ef NYKSpinneElectric, lead-acid (13T battery)534.6 mm / 7163 mm50 hm (30kn)Ka (Pi1)A new version (gerät 43 cp) of the TX tested for use on midget submarines (Marder/ Molch/ Seehund) with good results. It was planned for operational use on the Seehund from August 1945.TXIG7esZaunkönig IIElectric, lead-acid534.6 mm / 7163 mm57 hm (24 kn)Ke1 (Pi4c)TV with improved acoustic homing and depth mechanism. Operational. About 90 torpedoes in stock by September 1944 (a combination of new torpedoes and the ongoing upgrade of existing TV), but no certain record of usage during the war (five TXI torpedoes were recovered from the U-534, now on display in Birkenhead, UK. Four of the TXIs were picked for parts and blown up. Only one torpedo remains on display with the U-boat).TXIIG5eElectric, lead-acid (9T battery)534.6mm / 5550 mm30 hm (30 kn)Kb (Pi2)Short torpedo developed for the smaller type XVII coastal submarines. Was intended as a temporary solution until the ingolin-torpedoes were ready for operational use, but never fielded.TXIIIG7utK-ButtWalter turbine534.6 mm / 7163 mm30 hm (45 kn)Kb2 (Pi2)Ingolin/dekalin/helman/water fueled BO VI-turbine. Less fuel than the "Goldbutt", but 7 m length. Experimental development for the Seehund midget submarine. With sinker-mechanism. Approximately 60 torpedoes produced, planned for fielding by end of April 1945.TXIVG7aWet heater534.6 mm (527 for airtank) / 7163 mm25 hm (34 kn)Kc (Pi3)TI with changed buoyancy (max air pressure reduced from 200 to 100 kg/cm^2) developed as a replacement for TIIIc (failing batteries) for use on the Seehund midget submarine.

Never fielded.G7esLercheElectric (13T 210 Special battery)534.6 mm / 7163 mmunknownKe1 (Pi4c, TZ5)Development of the TV and TX with both active acoustic seeker and wire guidance. An operator in an U-boat could listen to the signal from the seeker and manually control the steering. Never fielded.G7tSauerstoff-turbine534.6 mm / 7163 mmunknownunknown (TZ2b, TZ5)Experimental development of the oxygen-turbine. Dropped in favour of the ingolin-engines.G7mKreismotor534.6 mm / 7163 mm270 hm (40 kn) / 180hm (48kn)unknown (TZ2b, TZ6)Experimental. Gasoline and compressed oxygen as fuel. Development was dropped in favour of the ingolin-engines.G7pElectric, with primary battery91.5hm (30kn) / 36.5 hm (40 kn)Experimental, using two primary batteries (magnesium-carbon and zinc-leadoxide) for propulsion. It was proposed to get very good speed and range, but development ended due to lack of resources.M5Wet heater736.6 mm / 4880 mmunknown (40 kn)unknownExperimental torpedo developed for coastal defence with a very large explosive charge and long range. Based on the TI with a 6-cylinder engine and only one speed-setting. 14 torpedoes built with 6 spare engines. Testing proved numerous "bottom-runners" due to failure of the launch and general poor quality of design and production. Two torpedoes were recovered and prepared for transport to the U.S. Ordnance Investigation Laboratory as museum pieces, but whether this was executed is doubtful.G7esGeier I and IIElectric534.6 mm / 7163 mmunknownActive sonar homing, experimental. Similar to the TV. Development-program with Luftwaffe, which ended up going for the "Pfau" instead. Otherwise successful design, which led to planning of a further development ("Geier III").LTImF5bWet heater450 mm / 5550 mm25 hm (40 kn)GK3a (Pi51)Luftwaffe F5b LTI torpedo adapted for use on Kriegsmarine Kleinstschnellboote.G7asWet heaterAcoustic homing, not fieldedG7uKlippfischWet heater Walter turbine95 hm (40 kn)Experimental intermediate model for the G7ut development (never planned for production). Ingolin/dekalin/Helman/Water-propulsion, using the aft-section and engine from the TI.G7utSchildbuttWalter turbine with seawater injection140 hm (45 kn) / 180 hm (40 kn)Experimental. Ingolin/dekalin/Helman/Water pressure-injection fueled turbine, later developed with the Steinwal-BO VI turbine.ZaunbuttIngolin Walter turbineAcoustic seeker from the TV combined with the ingolin-propulsion. Proposed shorter range than the Steinbutt, due to losing space for fuel in favour of electronics for the seeker. The project was in model-testing phase, when all plans and models were destroyed in a bombing raid. The project was not continued.Wal / SteinwalIngolin Walter turbine192 hm (45 kn)Experimental. Ingolin/dekalin/water pumped to the motor combined with Helman pressure-conveyor (BO VI-turbine). Development nearly finished by end of the war.G7f NYElectric12.5 hm (30 kn)Experimental surface-running torpedo remotely controlled by radio (several solutions were investigated, including control from airplane and shore-based relay-stations). Hexagon-shaped hull with hydrofoil wings and rocket-propulsion.G7mClosed-circuit propulsion180 hm (48 kn)Considered as replacement for both steam and electric propulsion. Never fielded.G7dOxygen-fueled wet-heater engine120 hm (45 kn)In early stages of development by April 1945. German oxygen-torpedo of similar design as the Japanese Type 93 'Long Lance'. Based on the G7a(TI) (reusing the airtank, the waterchamber and the enginecompartment) combined with the turbine from the G7ut. Expected to have improved performance over the TI, with almost no bubbletrack. Also it would have superior safety for handling/storage on board, as well as less loss of energy over time in storage, compared to the ingolin-torpedoes.G7urHechtWalter rocketExperimentalG7urMondfischWalter rocket700 hm (45 kn)Experimental.
