Here is how much of the THAAD missile system that the United Arab Emirates is interested in purchasing:

The US Defense Security Cooperation Agency announces [PDF] the United Arab Emirates’ request for 3 Terminal High Altitude Air Defense (THAAD) Fire Units with 147 THAAD anti-ballistic missiles, 4 THAAD Radar Sets (3 tactical and one maintenance float), 6 THAAD Fire and Control Communication stations, and 9 THAAD Launchers. This would represent the first foreign sale of the THAAD system.

The UAE is also requesting fire unit maintenance equipment, the heavy trucks that carry the THAAD components, generators, electrical power units, trailers, communications equipment, tools, test and maintenance equipment, repair and return, system integration and checkout, spare/repair parts, publications, documentation, personnel training, training equipment, contractor technical and logistics personnel services, and other related support elements. The estimated cost is $6.95 billion.

The principal contractor is Lockheed Martin Space Systems Corporation in Sunnyvale, CA (THAAD), and the sub-contractor is Raytheon Corporation in Andover, MA (radar).

The UAE will be requesting industrial offsets, which will be negotiated with these contractors. On the other hand, the UAE “does not desire a government support presence in its country on an extended basis.” A total of 66 contractor logistic support personnel could be stationed in United Arab Emirates for extended periods, and additional training and major defense equipment personnel may be in the United Arab Emirates for short periods of time, not to exceed 24 months.  [Defense Industry Daily]
