The Washington Post has a better article on that new Iranian sub. Iran also put launched its latest Moudge-class ship, named the Sahand. The articles call her a frigate (FFG) owing to her small size (1,500 tons standard displacement), but Iran has dusted off the designation of Destroyer Escort (DDE) and applided it to the class. One shouldn’t ignore these new surface ships from Iran: Their C-803 SSMs pack a hard punch. AEGIS is designed to meet this sort of threat, thankfully.
