A submarine that only costs 500 million? Is it for the bath tub?
No, it’s deadly quiet, big and carries the ability to lauch torpedoes and cruise missiles. Some variants can operate submerged for up to two weeks.
These things are no joke, and with well trained crews are as dangerous as anything we face. The only good news is that Egyptian crews likely will never have anything like the experience the Germans, Americans, Israelis, or Russians have.
