Iranian Defense Minister Brigadier General Mostafa Mohammad Najjar said on Tuesday that Iranian experts had produced new stealth micro submarines, vessels and lightweight aircraft, the English-language Press TV reported.
The new military developments come in line with Iran's supreme leader Ayatollah Ali Khamenei's order to develop exclusively made equipment to enhance the country's defense industry in face of possible threats, Mohammad Najjar said.
"Militarily-empowered countries can easily maintain their stability and independence," he said.
Khamenei on Saturday called for the production of exclusive military hardware for the country, asserting that in order to counter a potential attack, Iran should employ weapons the enemy is unfamiliar with.
The United States and its allies have accused Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program. Iran denies the charges and insists that its nuclear program is for peaceful purposes only.
The Bush administration said it focused on diplomacy to try to resolve Iran's nuclear issue, but insisted it will take "no option off the table."
Some observers believe that it is possible that the United States and Israel would attack Iranian targets for Tehran's suspicious nuclear program.
