Epirus and General Dynamics Land Systems Unveil Stryker Leonidas Integrated Counter-Electronic System


In just ten months, Epirus and GD transformed the system from concept to demonstrated field with the successful denial of several electronic targets

Strong points:

  • Successful integration of Epirus’ Leonidas high-power microwave (HPM) array with General Dynamics Land Systems’ Stryker ground combat vehicle, one year after companies signed a strategic team agreement in October 2021.
  • Leonidas’ software weaponry and modular architecture, combined with Stryker’s combat-effective track record, enable unprecedented counter-electronics capabilities for the maneuver force.
  • Tested and proven swarm counter capabilities and planned system enhancements will provide outclass capabilities against current and future electronic threats.

WASHINGTON, October 5, 2022 /PRNewswire/ — Epirus, a fast-growing technology company developing directed energy systems that enable unprecedented counter-electronic effects and General Dynamics Land Systems (GD), a global leader in providing ground-based combat solutions innovative, high-tech, next-generation products for customers around the world today announced the introduction of Stryker Leonidas.

After signing a strategic association agreement in October 2021the companies have successfully integrated the Epirus high-power microwave array into the Stryker ground combat vehicle and will unveil the integrated system at the Association of the US Army (AUSA) annual meeting and exposition at washington d.c.

Developed in less than a year, Stryker Leonidas was recently field demonstrated at a US government test site, successfully disabling individual drone targets and drone swarms. The integration of Leonidas, the world’s most powerful HPM phased array, with Stryker, the US Army’s largest and most reliable fleet of combat vehicles, brings counter-electronics capabilities to the front lines – providing a proven and cost effective layered defense solution for the maneuver force.

“The integration of Epirus’ Leonidas system with General Dynamics Land System’s Stryker vehicle provides the U.S. military with a cost-effective, maneuverable, and battle-tested defense capability against current and emerging threats to the warfighter,” said Leigh Madden, director general of Epirus. “Epirus’ culture of innovation and GD’s decades of experience in delivering industry-leading solutions will only continue as we work together to develop new capabilities.”

Leonidas’ counter-swarm effectiveness fills a pressing short-range air defense (SHORAD) capability gap for the joint force as the threat of drone swarming continues to endanger troops and civilians alike. abroad and in the country of origin.

The continued evolution of adversary swarming drone capabilities goes hand in hand with Epirus’ software weaponry capabilities, which allow the system to continually absorb new data, rapidly update its sophisticated waveforms and to extend the depth of its magazine for greater SHORAD mission assurance in all areas. With its open architecture, Leonidas can integrate with a range of command and control (C2) platforms to detect, track and defeat the growing deployment of drone technology by adversaries and non-state actors.

“The addition of Leonidas counter-electronics capabilities to the Stryker combat vehicle provides the joint force with unparalleled mobile protection against the ever-evolving threat of armed drones,” said Gordon Stein, vice president of US operations at General Dynamics Land Systems. “As the Army’s largest fleet of combat vehicles, Stryker is combat-proven, cost-effective, highly mobile, versatile, durable, and transportable and continues to be a highly sought-after platform beyond military formations. ‘Stryker Brigade Combat Team.’

Stryker Leonidas is the latest edition to Epirus’ suite of HPM systems – featuring the company’s ground-based Leonidas system for surface-to-air defense and Leonidas Pod, a one-of-a-kind mobile and compact HPM system. When deployed in tandem, the Leonidas product family creates a layered counter-swarm and counter-electronic protective field. Epirus is also actively exploring future next-generation threat defense capabilities.

Epirus (Booth #253) and GD (Booth #801) will be participating in this year’s AUSA Annual Meeting and Exhibition at washington d.c. (October 10-12) to showcase a full-size Stryker Leonidas prototype on display in the GD exhibit.
