The president said the USA is waging a full-scale economic war against the Islamic Republic, and the only reason why it is not attacking Iran is the high costs associated with such an invasion.
Rouhani said Iran's adversaries have for years been spreading Iranophobic propaganda that Tehran's military power and its missiles are a threat to the region's calm and tranquility.
Defence industry observers say Iran's air force is relatively minor, given that it roughly comprises of just a few dozen strike aircraft, largely Russian or American planes acquired before the 1979 Islamic Revolution.
"Why does the United States not attack us?
The Kowsar fighter jet was designed and manufactured by the Iranian experts to be used as a defensive tool for the country, Rouhani said at a ceremony marking National Defense Day on Tuesday. "Businesses all over Europe are seeing that the choice between doing business with Iran or doing business with the United States is very clear to them". "We are going to do other things to put pressure on Iran as well, beyond economic sanctions".
Saeqeh (Thunderbolt), which is a single-seat jet fighter was derived from the American Northrop F-5 and is the second generation of the Iranian Azarakhsh fighter. Last April he warned that terror proxy Hezbollah has powerful new missiles that could "turn Haifa and Tel Aviv into ghost-towns".
While Iran has attempted to "reverse-engineer" parts and weapon systems for these fighters, it has not been able to do a fleet-wide upgrade for over three decades even as the likes of Saudi Arabia and the UAE continue to buy billions of dollars worth of U.S. and European weaponry.
The US Department of State's electronic communication team refuted on its twitter account, Iran's "lie" about the new fighter jet it said it had recently produced.
The planning suggests USA bombers and long range missiles would be ready in "hours" to destroy 10,000 targets in Iran in just one fell swoop.
"All of those constraints are not going to be changed by updating the internal components".
Iran's air force has been limited to perhaps a few dozen strike aircraft using either Russian or aging US models acquired before the 1979 Islamic Revolution.
In the speech for the anti-Israel al-Quds Day, translated by the Middle East Media Research Institute (MEMRI), Hossein Salami said that "the life of the Zionist regime was never in danger as it is now".
"Today's unveiling is best understood as being for domestic propaganda purposes, coming at a time when the regime faces mounting internal pressure due to the re-imposition of United States sanctions, as well as escalating protests over its economic and environmental mismanagement and corruption". "But it should not be taken lightly".
