    Most of you know that the Germans started World War 2 with two kinds of torpedoes, namely, the TI and the TII. The TI is the older version that ran on gas/steam. The TII is the more widely known electric torpedo. The TI was usually a white color with a green painted head. Its fins were wider at the bottom and the propeller could be easily distinguished. The TII is also easily distinguished by its shorter length, sleek fins, and bronze/silverish color of the torpedoes body. It too supported a green painted top, (where the warhead lies). Both torpedoes could be detonated upon impact (using an impact fuse) or through proximity with a magnetic field.

    The TI was as stated a pre-war torpedo. It was a fast one, capable of running at 44knots ( at some instances even 45knots). At 44knots the torpedo went a distance of 5km at 40knots it went a distance of 7.5km, and at 30knots it went a distance of 12.5km. It was a very reliable torpedo, with a heavy kill ratio. A severe disadvantage with this torpedo is that it left a clear wake when it ran, giving the chance for the victim to swerve of if the lookouts view the wake in time. This was especially so when fired at DDs due to their high speed and low silhouette.

    The TII on the other hand left no wake, thanks to its electric propulsion system. It was considerably slower however at a maximum speed of 30knots with a range of 1.8km. The TII was considered the standard german torpedo of the war as so many of them were built. They suffered early on in the war due to the failures of its firing pistol and its depth keeping equipment. They were also prone to explode without contact when running in magnetic fire mode. This was especially so in the Norweigan campaign. As there werent many in the beggining of the war, these duds werent encountered in many numbers. Maybe the exception would be the Norweigan campaign. After that campaign however, these torpedoes were ironed out and they served with distinction. The real secret of the TII however is that it is extremely cheap to build. It cost 1/3 the price of the TI and took 1/3 of the manhours needed to construct the TI.
