Epirus raises $250M to scale directed-energy counter-drone system Leonidas

Mar 6, 2025

Key Points

  • Epirus raises $250 million to scale production of Leonidas, a directed-energy system engineered to counter drone swarms and conduct counter-electronics warfare.
  • Directed-energy defenses bypass kinetic systems' core vulnerabilities: they operate over stadiums and cities where firing projectiles is impossible, and handle volume threats kinetic alone cannot reliably manage.
  • 8VC founder Joe Lonsdale frames directed EMP as critical infrastructure across defense platforms, positioning the technology as complementary to rather than replacing kinetic solutions in both wartime and civilian security.

Summary

Epirus raised $250 million to scale production of Leonidas, a solid-state, software-defined directed-energy system designed to counter drone swarms and conduct counter-electronics warfare.

Directed-energy systems offer practical advantages over kinetic defenses. Non-kinetic systems can operate where firing projectiles into the air is impossible, such as over stadiums, in cities, and at civilian infrastructure. Kinetic air defense also faces a volume problem. A 100-drone swarm presents targeting challenges that kinetic systems alone may struggle to handle reliably.

Joe Lonsdale, founder of 8VC, an investor in Epirus, argues that directed EMP is becoming critical across defense platforms including bases, ships, vehicles, planes, and satellites. The capability serves both battlefield dominance and protection of combatants and civilians. Directed energy applies to wartime and civilian security contexts, positioning it as complementary to kinetic solutions rather than a replacement.

The funding round reflects confidence in both the technology and near-term demand from defense and critical infrastructure clients managing drone threats.
