The Strategic Defense Initiative-(SDI) or "Star Wars" started in 1983 with great propaganda from the US government, but ended in failure in 1993 at a total cost of $300? billion at 2012 prices.
The Bradley AFV program cost $24 billion, and many decades to develop. It is not particularly good either, rejected by the Israelis, but used by the Saudis who buy anything the USA makes without questions.
The F-35, cost is $400 billion and rising, maybe $1000 billion by 2018, when it is introduced to the American armed forces.
F-22 Lockheed Martin Raptor.......$65 billion...started in 1991, and finished in 2009.
VI and V2 rockets, weapons systems that had great potential, and large amounts of money and scientists with engineers were poured into the two projects, one for the army V2, and the other for the air force V1.......but their use, and their operational history was negligible. Therefore a waste of money, resources, waste of strategy, waste of skilled labor, and waste of national hope (the secret weapon that would defeat the enemy, BUT DIDN'T)
But these are highly industrialized, modern countries. The USA has a $15,000 billion economy, and an unofficial security budget of $1500 billion.
Iran by contrast is a poor, Third World country which cannot afford any waste.
Iran must first invest in (i) SAMs with a 150--250 km range....produce 300--400 such systems with the addition of 20,000 missiles in mass production. These should be deployed around Iran's borders, and coastline, with about 50 such systems around Tehran (ii) SAMs with a 30-50km range.....produce 3000 such systems with 120,000 missiles for the defense of key cities, military installation, and industrial instatllations. (iii) Finally SAMs with 10-15 km range...light shoulder fired with 20,000 such systems and 600,000 small missiles for the army.
AA guns should also be produced to shoot down enemy missiles.
Finally 4th generation jet fighters....copy of F-14 Tomcat, or the Su-30MKM.
Then priority number two, after Iran's airspace is secured, is the landmass from land bourne invasion.....Tanks, 155mm SP artillery, 120mm Mortar, 100mm AA/atk guns, Lt SAMs, ATGWs, night-sights.
However it must be stated that if the USA/NATO/Israel cannot defeat Iran's air-defense then no land invasion will take place. That is why air-defense must be given priority, over all else. Also the American military doctrine of "Shock and Awe"...against Iraq and Afghanistan specifically calls for massive air attacks first.
In that sense the development of fast attack boats, mini-submarines, frigates, destroyers, cruisers, aircraft carriers are not required. The Persian Gulf has shallow waters, where it is not easy to hide small or big submarines. The Submarines may create unwanted misunderstanding anyway. Iran will be wasting resources by expanding the size of the navy. Land based SSMs can deal with enemy targets in the Persian Gulf. Land based Jet fighters can deal with enemy targets in the Persian Gulf.
One does not waste ones time by going to Mashad via Ishfahan from Tehran.
Iran mini-subs difficult for US Navy to detect: Ex-US Navy Cmdr.

A former US naval commander says the Iranian military has a growing fleet of mini-submarines that is particularly difficult for the US Navy to detect and track.
The Iranian mini-submarines are “a huge problem for us,” MinnPost news website quoted retired Navy Commander Christopher Harmer, who was the director of future operations for the US Navy Fifth Fleet, stationed in Bahrain, from 2008 to 2009, as saying.
“They are a threat to us because they can disperse them throughout the Persian Gulf and the Arabian Sea, and it’s extremely difficult for us to track them,” he added.
Commander Harmer said that the US Navy is more accustomed to tracking large, Soviet-era nuclear-class submarines - something Iran knows well.
“Looking for small subs in shallow water is much more difficult, because the acoustics are so much more difficult - smaller makes less noise,” he stated.
Iran's Navy Commander Rear Admiral Habibollah Sayyari said on June 15 that the naval forces of the Islamic Republic will firmly counter any threat and deal with insecurity single-handedly.
Over the past years, Iran has made important breakthroughs in its defense sector and attained self-sufficiency in producing important military equipment and systems.
The country has repeatedly clarified that its military might is merely based on the nation's defense doctrine of deterrence and poses no threat to other countries.
