Why would Iran want to use a nuclear submarine?
Attack submarines: US carrier groups are well trained to counter such threats. Midget submarines are probably better for that.
Ballistic submarines: Well, get the missiles first! Put the missiles on a large diesel.
Underwater incursions/smuggling/surveillance: For this it would be good but a large diesel would suffice.
The thing is that (good) nuclear submarines are expensive (research, build, maintain, run) and that's before taking the infrastructure into account. Using the same money to strengthen other aspects of the armed forces would seem better to me (like build/copy more Kilos).
This is the only possible peaceful use for weapons grade Uranium.
If you want to claim you need highly enriched Uranium to power ship reactors, at least claim you want to build a "power relief" goodwill ship or something. Sounds better for PR than nuclear submarine.
The high enrichment allows to not reload fuel for decades. The current trend is too make a NPP which could serve 30-40 years and will be simply thrown away after it. You can imagine that encrichment will be at its highest.
Notice, that Brasil announced the same thing.
Honestly, I don't see how they will succeed. They haven't even managed to build their own diesel-powered submarine, other than the Ghadir midget submarine.
Just kidding.Breaking News: Iran has begun to design its first nuclear bomb, the Islamic Republic's Revolutionary Guards-linked Fars News has reported.
The Supreme Leader of Iran Ayatollah Ali Khamenei was quoted as saying Iran has begun "initial stages" of designing a peaceful nuclear bomb. "It is the right of the Islamic people to possess nuclear weapons", he said. "Iran has both the capability and the right to build a peaceful nuclear bomb", he added.
It would be the loudest boat in the water. Might hide the sound of their 'radar evading' speed boats. Where is the pro-Iran posters when you need them.
Yeah thats what we want, peaceful nuclear bombs. Yeah
