One of major naval production projects in Iran, it delivered Iran's first ever domestically-built warship in 2003. Abhijit Singh, a senior fellow at Observer Research Foundation described the project as "a proud testimony of Iran’s abilities at reverse engineering". According to Anthony Cordesman, Sina class ships have been "heavily updated" in comparison to the French-made La Combattante II type Kaman class. As of 2012, reportedly 10 ships were planned in this class.
Ships of this class are equipped with four box launchers with C-802 or Noor, as well as one main gun.
As of 2015, four ships (Sina 5 to 8) were under construction, two of them in the Caspian Sea and the other two at Bandar Abbas. In 2020, Farzin Nadimi of The Washington Institute wrote that production of these ships has not improved as expected.
