I hope your country will be able to make a even a 600ton submarine like below in the next 20 years:
Heck, what about a midget submarine? Can you make that?
Alternatively, you can wait and see if you can repaint a south korean submarine and claim you made it. You did something similar with their K-2 tank.
I wish your country haven 10% of the Iranian capability. Heck, learn to first even develop a mission computer for your UAV's:

Is there anything you people don't import?
Bro, these jokers are an import state. I can hardly name anything they make without importing most its components. Most of their stuff, is basically imported technology. Their tank, helicopter, even their so called "aircraft carrier" is just a Spanish ship.
