WASHINGTON — The State Department has cleared a possible $600 million foreign military sale of seven MH-60R Seahawk Multi-Mission helicopters to Greece.

Congress was notified of the sale July 12, according to an announcement posted to the Defense Security Cooperation Agency’s website. Congress is required to approve the deal.

The sale will include 10 APS-I 53(V) Multi-Mode Radars, 18 T700 GE-401 C engines as well as other radar, targeting and communications systems and equipment.

The order would also include 1,000 AN/SSQ-36/53/62 Sonobuoys, 100 Advanced Precision Kill Weapons System rockets, 30 MK 54 Torpedoes and M-2400 guns.
