are you dense?
I clarified this point several times German U-Boat AT ITS TIME was the most advanced designed and FOR ITS TIME it was expensive and highly technological. Fateh is hardly the most advanced submarine built today in the world. A German U-Boat could travel to Argentina from Europe, the Fateh cannot do that today.
Also by the end of the war, Germany was building the Wonder Weapon Submarine known as Type XXI
So yes Germany was way more advanced and capable 80 years ago than Iran is today. If you gave Nazi scientists the same technology, tools, advanced software, supercomputers that Iran has today they would run circles around Iran. Even if the Nazi scientists had to start at 1940’s knowledge while Iran starts at 2019.
So I won’t be impressed by this. I’m impressed by developments in UAV tech, air defense tech, cruise missile tech, even the ability to incorporate advanced subsystems on Mowj vessels. But not we “hope” to see Besat in 15 years.
