Remember these recent news about Saudi Arabia developing (or let's say participating in the development of) its THAAD system with Lockheed Martin?
Lockheed Martin to help Saudis develop THAAD requirement
Lockheed Martin will be awarded a contract to help the Royal Saudi Air Defence Forces (RSADF) develop their Terminal High Altitude Area Defense (THAAD) requirement, it was announced on 5 September.
The announcement was made via the US Federal Business Opportunities website, which said the US Missile Defense Agency would award a non-competitive contract to Lockheed Martin Missiles and Fire Control to provide “technical assistance to support requirement definition pertaining to the facilities design, system test, material fielding, training, system operations, maintenance, and sustainment concepts for RSADF THAAD".
No further details of the contract were revealed.
The THAAD system is designed to intercept ballistic missiles outside the earth’s atmosphere and has already been ordered by the United Arab Emirates (UAE) and requested by Qatar.

Reading between the lines, Saudi Arabia has its own requirements for the THAAD system.. meaning it will have a look on the technologies and chose the appropriate ones for itself, hence some components might be manufactured in KSA (tailor-made) to thwart any dependence on the US for operations..
Compare with SK where the THAAD system was send there as it is..
