Our nuclear subs cost a lot more than 500 million. These are not nuclear, right.
Good practice for the Israelis. How long do you think these would last? A week, two?
They can be quieter than a nuclear boat. They can spend long amounts of time at sea, for example, you could sail one from there to NYC.
These are significantly less expensive than our nuke boats. But they’re are not some WWII diesel boat.
Having 2 of them, i would imagine that they would be the focus of intensive intel and tracking by the Israelis and us. The Israelis have te advantage of uing the same boat and knowing it intimately. I would guess that in any war launched by Egypt against israel, they would both be quickly sunk. And the israelis would ever say a word.
And the Egyptians would get bored and use them for something stupid like landing terrorists in rubber boats.
