Canada has been cleared to purchase $387 million worth of MK 54 lightweight torpedo conversion kits, South Korea $313.9 million in SM-2 Block IIIB missiles, and Japan $313 million worth of AIM-120C-7 Advanced Medium-Range Air-to-Air Missiles, according to Defense News.

The notifications, posted on the website of the Defense Security Cooperation Agency, top $1.017 billion in potential sales. Raytheon is the primary contractor on all three of the potential sales.

As with all DSCA notifications to Congress, the sales must be approved on Capitol Hill and go through negotiations with the supplier, which can lead to changed quantities and dollar figures in the final agreements.
