Worth $311m, the agreement also involves the delivery of related equipment and services.
Apart from supplying the missiles to the US Army, the contract also requires JJV to provide production support for international customers, including Lithuania and Jordan.
The deal also includes the delivery of over 1,800 Javelins to replenish stocks in Ukraine.
Javelin Joint Venture president and Raytheon Missiles & Defense Javelin programme director Marek Wolert said: “As Javelin continues to demonstrate its reliability and effectiveness, its reputation as the premier battle-proven, fire-and-forget, precision anti-armour weapon grows.”
A shoulder-fired anti-tank weapon, Javelin can also be deployed from multiple platforms installed on tracked, wheeled, or amphibious vehicles.
It uses fire-and-forget missile guidance technology and provides a high level of survivability to the user.
Equipped with an imaging infrared seeker, the missile can be used during the day and at night in all weather conditions.
The Javelin missiles are manufactured jointly by JJV.
JJV vice-president and Lockheed Martin Javelin programme director Dave Pantano said: “With usage increasing across the globe, the Javelin Joint Venture is working closely with the Army to meet these increased demands and deliver this critical precision weapon system to domestic and international customers.
“Our team continues to remain committed to delivering reliable and battle-proven products that demonstrate performance excellence.”
Javelin has been undergoing frequent upgrades to meet changing operational needs and is likely to be in service with the US Army until 2050.
So far, the JJV has manufactured over 50,000 Javelin missiles and 12,000 reusable Command Launch Units.
