The Defense Security Cooperation Agency announced that the U.S. State Department has approved the sale of long-range missiles and rockets worth an estimated $10 billion to Poland.

The DSCA said it has already informed Congress of the proposed sale of the M142 High Mobility Artillery Rocket Systems, which Ukraine has used against Russia in their ongoing conflict.

Poland is seeking to purchase 18 of the launchers, along with Army Tactical Missile Systems and Guided Multiple Launch Rocket System Alternative Warheads and launcher loader module kits. 

The contract also includes Guided Multiple Launch Rocket System Unitary pods and Guided Multiple Launch Rocket System Extended Range Alternative Warhead pods.

The foreign military sale contract is expected to support the foreign policy goals and national security objectives of Poland, a NATO ally, thereby helping make the United States safer, the DSCA said. 

The HIMARS system will allow Poland to modernize its armed forces and defend against regional threats but will not affect the military balance in the region, according to the agency. 

Lockheed Martin, based in Grand Prairie, Texas, will be the prime contractor for the sale.
