WASHINGTON — The U.S. State Department has cleared a possible $600 million foreign military sale of seven MH-60R Seahawk multimission 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-401C 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.

The principal contractor is Lockheed Martin Rotary and Mission Systems in Owego, New York.

Greece intends to buy the helicopters in February as part of a modernization effort.

Greek officials have recently sought closer ties to the U.S. military amid worsening relations between the U.S. and Turkey over the latter’s acquisition of the Russian S-400 air defense system.

The U.S. and Greece have discussed expanding operations at Larissa Air Base, central Greece, including the stationing of KC-135 tankers and unmanned aircraft. They are also looking to expand training opportunities.
