SM-3 Missile Defense Fraud
Most American politicians support spending on a national missile defense system. However, some technical issues remain beyond our level of sophistication. Continued research and development is justifiable, but military contractors discovered that money can be made by pretending a system exists. In 2011, I wrote about a fraudulent missile defense scheme. Major military contractors collect billions of dollars in taxpayer funds each year to build and deploy SM-3 missiles worldwide to protect against Intermediate Range Ballistic Missiles (IRBM) and Inter-Continental Ballistic Missiles (ICBM), even though they lack the range to hit them.
The bigger the missile the greater the range, which I explain in detail in my 2011 article. The SM-3 size is constrained by the requirement that it fit into the Navy MK-41 launcher. (loading pictured) Early versions of the SM-3 could only reach 90 miles high, while IRBMs and ICBMs arc 300-750 miles overhead. Raytheon was given billions of dollars over two decades to increase range by tweaking engine performance and adding propellant by maximizing the size of a missile that can fit in an MK-41. This nearly doubled the SM-3's altitude, yet remains far too limited for American and European missile defense. The most range demonstrated is listed by the great missile website Astronautica:
More recent tests no longer disclose the altitude at intercept since Congress might ask why longer range intercepts are not attempted. This limitation resulted in creative marketing that led to blatant fraud as salesmen claimed the SM-3 can be used for European and American national missile defense. As I explain in my 2011 article, missile contractors and allies in the Pentagon provided range data to Congress that assumed enemy missiles would fly a low "depressed trajectory" of less than 150 miles high directly over SM-3 missile launchers so they could hit them, rather than a normal "lofted" ballistic trajectory of over 300 miles high. This would also require a row of hundreds of SM-3 launch sites to protect Europe since each site could only cover a 40 mile swath.
Since this concept was absurd, a covert effort began to lie about SM-3's range. Raytheon and its conspirators simply claimed the SM-3 can protect against IRBMs and ICBMs! There is no computer model nor projected SM-3 performance data on any Pentagon or Raytheon website to back this claim. This bogus range data first appeared in 2013 in an military industry funded website "Breaking Defense" where a Dutch assistant professor announced that an SM-3 can hit targets 1350 miles away! He included several nice charts, but cited no source data. This false claim was immediately inserted into the SM-3 Wikipedia entry and appeared in news stories and websites. The SM-3 Wikipedia entry magically improved range from 130 miles to 1350 miles! I searched websites and news stories attempting to learn how anyone could justify the idea that SM-3s can shoot down long range missiles. I finally found the answer in a 2015 Rand report:
"The methodology employed to perform the calculations discussed in this report assumes
impulsive interceptors and missiles that spontaneously obtain their entire velocity immediately
upon launch. This assumption is made to simplify the mathematical complexity. Similarly, the
calculations were done assuming no air drag and a nonrotating Earth. The modeling of the
interception was done assuming perfect tracking information and no countermeasures from the
target missile. The end game of the interception process was also not modeled. Given the ranges
and times involved in comparing the kinematic reach of different interceptors, these assumptions
and simplifications are reasonable for a first-order estimation."
This was buried in a long, detailed report that shocks anyone with a basic knowledge of flight. Using just maximum velocity to determine range "to simplify the mathematical complexity" could be justified to teach elementary school children multiplication: (distance x speed). Calculating acceleration and air resistance as fuel is consumed and air density lessens requires complex calculus, not to mention the pull of gravity. Fortunately, American scientists have performed this task on chalkboards since the 1930s, and now we have computers! This is required for all space launches! There are even websites with simple on-line calculators where anyone and punch in basic data to get a good "first-order estimation." The SM-3 program began two decades ago, not two weeks ago, so Raytheon is well beyond "first-order estimations".
An outlandish simplification in the Rand report was "calculations were done assuming no air drag". Air resistance is the primary obstacle to intercept. A surface launched missile must catch the target missile that already has a sizable lead. Air resistance slows acceleration and burns more fuel. High speed air friction causes skin heating that can melt the nose or cause it to break open. As a result, missiles in the atmosphere are limited to Mach 3-5. The term MaxQ refers to the maximum velocity a missile can safely fly at a certain altitude without risking self-destruction. One could argue that once a missile reaches 100 miles above Earth, atmospheric particles are so few that air drag can be discounted, but some 90% of the Earth's gravity remains so after burnout a missile is pulled back to Earth and away from its target.
Burnout velocity is the maximum speed a missile reaches just as its fuel is exhausted. The latest SM-3 missile deployed is the SM-3-IIA, which claims a burnout velocity of 4.5 km/sec or 10,000mph (Mach 13!). This may be possible after the missile exits the Earth's atmosphere after two stages are dropped and fuel exhausted. But most of the missile flight is at less than Mach 4 because of "air drag" and once burnout occurs gravity pulls it back down. Therefore, very long range intercepts require the missile be aimed along an indirect arcing ballistic flight path that is much longer, so long that they cannot catch missiles unless they are flying toward the missile defense launch site. Russian missiles are aimed to fly the shortest route to the USA over the arctic. There is no way any missile fired from Central Europe can catch them!
Yet these impossible conditions were still not enough since the Rand report also assumes "missiles that spontaneously obtain their entire velocity immediately upon launch." Of course several seconds are needed for any missile to reach maximum velocity even without gravity or air resistance, and so G-forces do not squash components. Nevertheless, these calculations assume that it begins flight at its maximum burnout velocity to further falsify performance calculations.
The Rand report is an interesting example of politics. Rand provides detailed outside analysis to support Pentagon plans. However, it is run by smart people and some have integrity. They knew the SM-3 range was greatly inflated, perhaps from reading my 2011 article, and insisted on the methodology. They included the paragraph above in blue to warn experts that the entire report is bogus, so Rand deserves some credit for exposing this fraud. Are there people in Congress, the major media, or the Pentagon willing to act on this fraud?
