Wolfspeed Secures $1.5B DOD Loan for GaN and SiC Capacity at Marcy and Durham Fabs

Wolfspeed signed a $1.5 billion conditional loan agreement with the Defense Department's Office of Strategic Capital on October 8 to expand gallium nitride and silicon carbide production at its Marcy, New York and Durham, North Carolina facilities. The funds will also support radiation-hardened device development and low- and high-voltage power device manufacturing for missile defense, electronic warfare, and propulsion systems.

The timing clusters three major semiconductor and advanced-manufacturing commitments within 24 hours—Raytheon's $6.3B missile contract, Anduril's $2.9B submarine-component facility, and now Wolfspeed's $1.5B loan. That pace suggests the administration is front-loading capital deployment before congressional dynamics shift in Q4 2026. Wolfspeed's GaN expansion directly feeds the SM-3 Block IB's RF power and seeker upgrades; if production delays on either end slip past 2028, the Navy faces a gap in its intermediate-range air-defense inventory across the Pacific.

WHY IT MATTERS

Wolfspeed now holds the second-largest DOD capital commitment in the current industrial-surge cycle—behind Anduril's $2.9B Navy contract (announced October 7) and roughly equal to PsiQuantum's $150M quantum loan (announced October 8).

The $1.5B commitment forces a capacity decision on the Hill: gallium nitride is the binding constraint for next-generation radar and RF power systems across INDOPACOM and European NATO, and Wolfspeed's Marcy line is the only domestic high-volume GaN epitaxy fab. If the initial $600M tranche clears by Q2 2027, production ramps by late 2027, which aligns with the Raytheon SM-3 Block IB production cadence (awarded $6.3B October 8) and the Army's next radar procurement cycle. Watch whether the loan conditions require Wolfspeed to commit to long-term offtake agreements with defense primes—if not, the fab runs at commercial utilization rates and the DOD subsidy becomes a capacity hedge with no guaranteed military supply.

WHAT THIS DOESN’T TELL US

Does the conditional loan require Wolfspeed to reserve a minimum percentage of Marcy and Durham output for DOD customers, or is the facility free to serve commercial RF markets at higher margins?
