Germany and Israel Aerospace Industries (IAI) on Sunday signed a $3.1 billion contract expanding the prior Arrow 3 defense system from the $3.5 billion initial Arrow contract signed between the parties two years ago.

The contract signing follows the December 17 approval of the deal by the German Bundestag and brings the total earnings on the two deals to over $6.5 billion, representing the largest Israeli defense export deal ever.

The announcement comes only one month after the initial Arrow 3 battery Israel provided to Germany was deployed at a major ceremony at Holzdorf Air Force Base, attended by The Jerusalem Post.
