An initial funding tranche of $338 million has been released at the time of contract signing. Officials did not disclose detailed quantities but confirmed that the contract includes munitions, spare parts and diagnostic equipment.
The contract also covers production for international customers under the Foreign Military Sales program. These include Belgium, Canada, Finland, Germany, Italy, Norway, South Korea and Switzerland.
More than half of the initial funding tranche, amounting to $171.5 million, is financed by these export customers. All of the countries involved have previously ordered Lockheed Martin F-35A Lightning II multirole combat aircraft.
The GBU-53/B StormBreaker is designed to engage both stationary and moving targets. Its multi-mode guidance system enables precision strikes under various operational conditions.
Weighing approximately 93 kilograms, the weapon allows aircraft to carry larger quantities per mission. This increases the number of targets that can be engaged while limiting collateral damage.
RTX has already delivered several thousand StormBreaker bombs to the U.S. Department of Defense. A smaller number has also been supplied to export customers, including Australia.
The StormBreaker is expected to become a standard air-to-surface weapon across multiple combat aircraft platforms. Officials said its continued production supports both domestic and allied operational requirements.
