United States defense sector faces challenges due to rare earth magnet reliance

The record

Written from the 1 report below. Nothing here is unsourced.

The United States defence sector relies heavily on samarium, requiring an estimated 50 to 100 tons each year.
However, domestic US capacity to produce this rare earth material is very limited.
As a result, the sector depends on rare earth magnets from China, creating a new strategic challenge.
This reliance matters because it exposes US defence supply chains to potential foreign dependency risks.
