Fusion Startups Forge New Ties with Defense Sector

Source: TechCrunch - Published: 13 Sep 2026 16:15

Fusion power startups are increasingly partnering with defense companies, reviving a historical connection between fusion technology and national security. As funding for climate tech has slowed, these startups are seeking alternative financial support, leading to collaborations that leverage their advanced laser technologies for defense applications.

Recent partnerships include Xcimer's deal with RTX, which allows for the exploration of using powerful lasers in defense systems. Pacific Fusion is also engaging with the National Nuclear Security Administration to enhance high-energy-density fusion experiments, indicating a strategic shift towards integrating fusion technology into national defense initiatives.

Watch for how these partnerships evolve, particularly Xcimer's integration of laser technology into defense systems. The implications for national security and energy innovation could reshape funding landscapes and operational strategies in both sectors.
