The Superkavitierender Unterwasserlaufkörper (lit.Supercavitating Underwater Running Body, formerly known as Barracuda) was a German close-range supercavitating torpedo technology demonstrator [1] designed by the Diehl BGT Defence (now Diehl Defence) and developed in cooperation with the German Navy.
A supercavitating torpedo is a torpedo using the effect of supercavitation to create a bubble around the torpedo to move at high velocity under water. The following is a list of supercavitating torpedoes which have been developed or are in development.
ST3000DM001 as external hard drives in retail packaging. Anand Lal Shimpi of AnandTech noted that the ST3000DM001 is "a bit faster in sequential performance than the old Barracuda XT, at lower power consumption" and that "Seagate appears to have optimized the drive's behavior for lower power rather than peak performance".
In 1993, Seagate released the first Barracuda drive, with the ST11950. The drive had a capacity of 2.03 GB (1.69 GB formatted), was available with FAST SCSI-2 (N/ND models) or WIDE SCSI-2 (W/WD models) interface, and was the first hard drive ever to have a spindle speed of 7200-RPM.

The steam propels the torpedo in a closed Rankine cycle, [5] supplying power to a pump-jet. This propulsion system offers the very important deep-water performance advantage in that the combustion products— sulfur and lithium fluoride —occupy less volume than the reactants, so the torpedo does not have to force these out against increasing ...

The Barracuda class nuclear reactor incorporates several improvements over that of the preceding Rubis. Notably, it extends the time between refueling and complex overhauls (RCOHs) from 7 to 10 years, enabling higher at-sea availability. In support of special operations missions, the Barracuda can also accommodate up to 15 Commandos Marine.
