Air Defense: THAAD Battery Formed
   Next Article → MURPHY'S LAW: Pilots (Literally) Rule
April 16, 2008: The U.S. Army is forming the first of four anti-ballistic missile (ABM) batteries. This unit will be ready for combat in two years, using the THAAD missile. The other three batteries will be in service within five years.  Fifteen months ago, there was a successful test of THAAD (a SCUD type target was destroyed in flight) using a crew of soldiers for the first time, and not manufacturer technicians, to operate the system.


Each THAAD battery will have 24 missiles, three launchers and a fire control communications system. This will include an X-Band radar. The gear for each battery will cost $310 million. The 18 foot long THAAD missiles weigh 1,400 pounds. This is about the same size as the Patriot anti-aircraft missile, but twice the weight of the anti-missile version of the Patriot. The range of THAAD is 200 kilometers, max altitude is 150 kilometers, and it is intended for short (like SCUD) or medium range (up to 2,000 kilometer) range ballistic missiles. THAAD has been in development for two decades. Ultimately, the army would like to buy at least 18 launchers, 1,400 missiles, and 18 radars.


THAAD is  a step up from the Patriot PAC-3 anti-missile (which is an anti-aircraft missile adapted to take out incoming missiles). The PAC-3 works, but it has limited (20 kilometers) range. The navy has also modified its Standard anti-aircraft missile system to operate like the PAC-3. This system, the RIM-161A, also known as the Standard Missile 3 (or SM-3), has a longer range than THAAD (over 500 kilometers) and max altitude of 160 kilometers. missiles. The Standard 3 is based on the failed anti-missile version of the Standard 2, and costs over three million dollars each. The Standard 3 has four stages. The first two stages boost the interceptor out of the atmosphere. The third stage fires twice to boost the interceptor farther beyond the earth's atmosphere. Prior to each motor firing it takes a GPS reading to correct course for approaching the target. The fourth stage is the 20 pound LEAP kill vehicle, which uses infrared sensors to close on the target and ram it.


Thus the U.S. has three anti-missile systems, although one of them currently only operates from warships (cruisers and destroyers that have been equipped with the special software that enables the AEGIS radar system to detect and track incoming ballistic missiles.)

Good to see we are working towards the promise of SDI.

Just curious, because I don't know (just looking to learn here)... what is better for ABM... SM-3 or THAAD?  Why not just select the best missile and use common systems for economy?  I'm sure there's a good reason, and I know SM-3 is AEGIS based.. but if the SM-3 is superior.. why didn't army seek to develop a ground based AEGIS and Ground launched SM-3 variant??   If  THAAD is that good, then great for them.. but I wonder if it can target aircraft too and cruise missiles??  Or will it have to deploy with MEADS complement for that?
Perhaps THAAD could be deployed in Poland and NATO bases, instead of GBI, to lesson hysteria from Kremlin and defuse the politics?  And just warn Iran that if they ever deploy Long range strategic ballistic missiles, they will be countered in asymmetrical ways?  So as to more flexibly cover the bases?  Just some thoughts.

they're companion and complimentary systems per se.  there is no such animal as "better" as they fulfill different operational response requirements.

1) they're disparate capabilities
2) disparate capability means redundancy at the engagement opportunity level
3) redundancy = milspec philosophy at the macro level
