New models of vessels and submarines are on the way, Minister of Defense Brigadier General
Ahmad Vahidi said, IRNA reported.
Vahidi said his Ministry has, along with the Islamic Republic Army's Navy Force, been able to produce new systems and arms.
He said construction of different kinds of navigation and control systems is on agenda. "Part of the systems have been built and produced today and the remaining portion is in the verge of construction."
On Yunis Submarine, General Vahidi said the submarine showcased Iran's authority.
"The move (the first extra-territorial mission of the Islamic Republic Army Navy Force's submarine) marked a highly important step showing authority and strength of the Islamic Republic of Iran thanks to our dear ones (forces) in the Islamic Republic Army Navy Forces; that happened for the first ever."
Early in July, Iran's Yunis submarine, sailing alongside warships of the 14th fleet of the Iranian Navy, returned home following a nearly two-month-long mission in the Red Sea and the Gulf of Aden.
The deployment of the Iranian military submarine in the Red Sea represented the first such mission by the country's naval forces in far-off waters.
In February, two Iranian Navy ships, Khark and Alvand, passed through the Suez Canal, a strategic international shipping route in Egypt, for the first time since the victory of the Islamic Revolution in Iran in 1979.
Iran has repeatedly assured other nations, especially its neighbors, that its military might poses no threat to other countries, insisting that its defense doctrine is based on deterrence.
