The various types of the German torpedoes T1 - (G7a) Diameter : 53.34 cm Length : 7.163m Weight : 1538 kg Propulsion : Thermic energy Power : 350 hp Range & Speed : 44 knots to 5,000m / 40 knots to 7,500m / 30 knots to 12,500m Warhead : 280 kg Guidance system : Direct firing Fat or LUT Description : The prewar issue torpedo T I was propelled by a steam engine (Compressed air). It was quite reliable and could make up to 12.5 kilometers. Anyway this torpedo type left a stream of bubbles after it, because of its propulsion, giving the targeted ship a chance of seeing it coming. Therefore the T I was to be used at night. T1 - (G7ut K. But Type) Diameter : 53.34 cm Length : 7.163m Weight : 1309 kg Propulsion : Walteer Turbine Power : 425 hp Range & Speed : 45 knots to 2,800m Warhead : 280 kg Guidance system : Direct firing Description : T1 - (G7a Type) Diameter : 53.34 cm Length : 7.163m Weight : 1352 kg Propulsion : Thermic energy Power : 280 hp Range & Speed : 34 knots to 2,500m Warhead : 280 kg Guidance system : Direct firing Description : T2 - (G7e) Diameter : 53.34 cm Length: 7.163 m Weight: 1608 kg Propulsion: Electric motor Power : 100 hp Range & Speed: 30 knots at 5,000m Warhead : 280 kg Guidance system : Direct firing Description : The standard issue German torpedo of W.W.II. This all battery powered torpedo type left no trails on the surface and was suitable for attacks in daylight. A great improvement! However the electric torpedo could not make as good range as the steam powered ones and it had to be looked after, getting serviced, every three or four days. Before the Norwegian campaign the T II had problems with its depth keeping equipment as well as with its firing pistol. T3 - (G7e) Diameter : 53.34 cm Length : 7.163 m Weight : 1608 kg Propulsion : All electric propulsion system Power : 100 hp Range & Speed : 30 knots at 5,000m Warhead : 280 kg (TNT - Trinitrotoluene) (HND - hexanitrophenylamine) Guidance system : Direct firing or Fat Description : T III was "the same" as the T II though it was fitted with an influence fuse! T3a - FAT (G7e) Length: Weight: Propulsion: Range & Speed: Warhead: 7.163 m ? Electric motor 7.5 km at 30 kts 274 kg (280 kg ?) The FAT (Flachenabsuchender torped = area searching torpedo) was a pattern running torpedo made especially for convoy attacks. The torpedo was pre set to run in a zig zag pattern! First it went straight, turned over to left or right and proceeded for 800 or 1600 meters making the next turn opposite. A lethal weapon getting inside a convoy. T3b - (G7a) Length: Weight: Propulsion: Range & Speed: Warhead: 7.163 m 1352 kg Electric motor ? km at 18.5 kts 280 kg Made for the midget sub "Marder". T3c - (G7a) Length: Weight: Propulsion: Range & Speed: Warhead: 7.163 m 1352 kg Electric motor ? km at 18.5 kts 280 kg Made for the midget sub "Seehund". T3d - (G7e) Length: Weight: Propulsion: Range & Speed: Warhead: 11.0 m 2200 kg Electric motor ? km at 9 kts 280 kg This torpedo was also named "Dackel". Made for special operations. T4 - (G7es) Falke Diameter : 53.34 cm Length: 7.163 m Weight: 1400 kg (approx.) Propulsion: Electric motor Power : 32 hp Range & Speed: 7.5 km at 20 kts Warhead: 274 kg (280 kg ?) Guidance system : Acoustical self-guidance Description : Also known as the "Falke" this type was the first homing torpedo as It was fitted with a passive acoustic homing device and made to be launched against escort vessels. Its slow speed and the fact that it had no magnetic detonator made it to be a small help in the warfare.A very small number of the T IV were used, when the next generation of this type was at hand. T5 - (G7es) Zaunk├Ânig type Diameter : 53.34 cm Length: 7.163 m Weight: 1495 kg (approx.) Propulsion: Electric motor Power : 55 hp Range & Speed: 5.7 km at 24 kts Warhead: 274 kg Guidance system : Acoustical self-guidance Description : Also known as "Zaunk├Ânig 1" This torpedo type was (as the "Falke") an acoustic homing torpedo to be searching for the propeller noise of the target (actually searching for the largest noise in the area). The development for creating accurate homing torpedoes had started as early as in the mid 30s but made slow progress. The T V was an improved version of the acoustic torpedo. It was faster and had both a magnetic and a contact detonator. The Zaunkonig had even better detection equipment with better sensitivity locating the propeller sounds. But this torpedo also had its weak points. In hard weather conditions it was detonating to early as well as it could detonate far behind or beyond a ship. The allied forces soon found out that the active range of its detection gear was only sensitive to ships sailing at about 15 knots! Skippers got to know that if they either lowered the speed or went faster than 14-16 knots the torpedo would get serious problems spotting them. They also developed anti "GNAT" (as the allies called the torpedo) devices dragged after an escort vessel making a loud noise to attract possible homing torpedoes in the area. T8 - G7ut Steinbutt Type Diameter : 53.34 cm Length: 7.163 m Weight: 1730 kg Propulsion: Walteer turbine Power : 430 hp Range & Speed: 8 km at 45 kts Warhead: 280 kg
