The US is investing $6 billion in manufacturing of arms for shipment overseas. This is being done so that 100,000 155mm shells can be made instead of 30,000 a month by the end of 2025. Three production lines at a cost of $1 billion at General Dynamics factory in Texas are put in place to reach 50,000 shells a month. This ammunition is needed in Ukraine where thousand of shells are used each day.
