Iranian naval forces accomplished all their missions in the fourth stage of the "Unity 87" wargames inspected by the lieutenant commander of the Islamic Republic Army, General Seyed Abdul-Rahim Mousavi, and Navy Commander, Admiral Habibollah Sayyari.
Iranian submarines, marines, PT-boats, missile-launcher gun boats and medium-range Nasr 1 missile all fulfilled their missions successfully in the different phases of the fourth stage of the drills.
The surface-to-surface Nasr-1 missile, which was tested in the Sea of Oman operational region on Saturday, was fired from a warship and hit its target at a distance of 30 km (19 miles) and destroyed it. It was the first test of the new, medium-range missile.
The Unity 87 war game started on December 2 for a six-day military exercise with over 60 warships as well as fighter jets, unmanned aerial vehicles, torpedoes, light and heavy submarines, gunboats.
Admiral Sayyari said on Sunday that the navy is capable of defending coastal borders and waters of the country.
The maneuver operations completed successfully and the navy forces could even do better than what was expected, he added.
He then refused to compare Iran's navy forces with those of others, saying, "I will not compare Iran's navy with any other country, our strategy is defensive and our goal is clear, our mission is determined and that is safeguarding the country's interest."
"We are so courageous in defending our interests that no country dares to assault our borders, we have always had the first and strongest voice in the region and will have the same strength."
The war game was codenamed "Unity" and that is to tell every country in the region that all must be unified and must preserve regional security on their own, he added.
"The message of the maneuver is friendship and unity and that keeping regional security and peace is only well-done by ourselves," the commander said.
Sayyari had also earlier told the media that the maneuver aimed to "increase the Iranian naval forces' combat preparedness, test and use domestically-made naval weaponry and enhance the country's deterrence capability".
The Iranian navy has developed exclusive military equipment such as stealth micro submarines and lightweight aircraft in an effort to maintain the sovereignty and integrity of the country's coastal waters.
Iran has launched a domestic weapons procurement campaign aimed at improving its defense capabilities and has announced the development of 109 types of advanced military equipment over the past two years.
Tehran has also conducted several high-profile wargames this year to display its full preparedness to possible enemies.
The Untied States and its staunch ally Israel have both intensified threats of military action against Iran in recent months.
A US attack on the Syrian village of Sukkariyah on October 26, has raised speculation about the likelihood of a US unilateral strike on the Islamic Republic.
Speculation that Israel could also bomb Iran mounted after a big Israeli air drill in June. In the first week of June, 100 Israeli F-16 and F-15 fighters reportedly took part in an exercise over the eastern Mediterranean and Greece, which was interpreted as a dress rehearsal for a possible attack on Iran's nuclear installations.
Israel and its close ally the United States accuse Iran of seeking a nuclear weapon, while they have never presented any corroborative document to substantiate their allegations. Both Washington and Tel Aviv possess advanced weapons of mass destruction, including nuclear warheads.
Iran vehemently denies the charges, insisting that its nuclear program is for peaceful purposes only. Tehran stresses that the country has always pursued a civilian path to provide power to the growing number of Iranian population, whose fossil fuel would eventually run dry.
Iran has warned that it would target Israel and its worldwide interests in case it comes under attack by the Tel Aviv.
The United States has also always stressed that military action is a main option for the White House to deter Iran's progress in the field of nuclear technology.
Iran has warned that in case of an attack by either the US or Israel, it will target 32 American bases in the Middle East and close the strategic Strait of Hormoz.
An estimated 40 percent of the world's oil supply passes through the waterway.
Meantime, a recent study by the Institute for Science and International Security (ISIS), a prestigious American think tank, has found that a military strike on Iran's nuclear facilities "is unlikely" to delay the country's program.
In a Sep. 11 report, the Washington Institute for the Near East Policy also said that in the two decades since the Iran-Iraq War, the Islamic Republic has excelled in naval capabilities and is able to wage unique asymmetric warfare against larger naval forces.
According to the report, the Islamic Revolutionary Guards Corps Navy (IRGCN) has been transformed into a highly motivated, well-equipped, and well-financed force and is effectively in control of the world's oil lifeline, the Strait of Hormuz.
The study says that if Washington takes military action against the Islamic Republic, the scale of Iran's response would likely be proportional to the scale of the damage inflicted on Iranian assets.
Intensified threats by Tel Aviv and Washington of military action against Iran contradict a recent report by 16 US intelligence bodies which endorsed the civilian nature of Iran's nuclear plans and activities.
Following the US National Intelligence Estimate (NIE) and similar reports by the IAEA head - one in November and the other one in February - which praised Iran's truthfulness about key aspects of its past nuclear activities and announced settlement of outstanding issues with Tehran, any effort to impose further sanctions or launch military attack on Iran seems to be completely irrational.
The February report by the UN nuclear watchdog, the International Atomic Energy Agency, praised Iran's cooperation in clearing up all of the past questions over its nuclear program, vindicating Iran's nuclear program and leaving no justification for any new UN sanctions.
The UN nuclear watchdog has also carried out at least 14 surprise inspections of Iran's nuclear sites so far, but found nothing to support West's allegations.
Following the said reports by the US and international bodies, many world states have called the UN Security Council pressure against Tehran unjustified, demanding that Iran's case be normalized and returned from the UNSC to the IAEA.
