Lockheed Martin will invest more than $1 billion to localise military manufacturing in Saudi Arabia, Ray Piselli, its vice president of international business, told broadcaster Asharq Business on Tuesday.

The news comes a day after Saudi Arabia's General Authority for Military Industries (GAMI) said it had joined forces with Lockheed Martin to make some parts for its THAAD missile defence system in the Middle East nation.
