Egyptian Romeo Class submarine

The Romeo class (Project 633) is a class of Soviet diesel-electric submarine, built in 1950s. The origin of the Romeo class can be traced to the World War II German Type XXI Elektroboote U-boat. At the end of World War II, the Soviets obtained several Type XXIs, from which they were able to obtain certain key technologies. These technologies assisted in the design of the Zulu- and Whiskey-class. Further improvements on the design lead to the Romeo class.

By today's standards, the Romeo class submarine is considered obsolete, but still have some value as training and surveillance vessels.
