US ‘Golden Shield’ Takes Form in First Exercise With Micro-Missile Interceptors
AI Analysis
The US Army conducted its first live exercise of the 'Golden Shield' concept using Harpe micro-missile interceptors for counter-drone defense. Developed by Perseus Defense, these cost-effective interceptors are designed to target Group 1 and Group 2 UAS, integrating cross-platform sensing and layered defense strategies.
Key Takeaways
- Golden Shield integrates Harpe micro-missile interceptors for layered counter-drone defense.
- Harpe interceptors are priced under $10,000 per unit and target Group 1 and Group 2 UAS.
- The system demonstrated cross-platform sensing and command-and-control software for targeting.
- Developed by the 1st Cavalry Division, the system aims for formation-based protection.
- Perseus Defense rapidly advanced the Harpe program from concept to live-fire testing within six months.
Why It Matters
The introduction of the Golden Shield concept represents a significant advancement in cost-effective counter-UAS capabilities for the US Army. By integrating micro-missile interceptors and cross-platform sensing, the system enhances tactical flexibility and layered defense, crucial for addressing evolving drone threats on the battlefield.

The US Army’s “Golden Shield” concept is beginning to take shape through its first live exercise integrating micro-missile interceptors designed for counter-drone defense.
Framed as a lower-tier complement to broader air defense efforts, the system was tested with Harpe micro-missile interceptors developed by California-based Perseus Defense against Group 1 and Group 2 unmanned aerial systems (UAS).
In the demonstration, radar and command-and-control software provided targeting cues to enable launch engagements and active guidance of interceptors against incoming drone threats.
The exercise also marked an early test of cross-platform sensing, where one system detected and identified a hostile drone before relaying data to a separate launcher platform tasked with completing the intercept.

US Army officials described the approach as part of a shift toward layered, formation-based protection.
“The future is formation-based layered protection, and this is the start of that,” said Alfred Grein, executive director for Research and Technology Integration for the US Army Capabilities Development Command Ground Vehicle Systems Center.
“Some [of the systems] are more mature than others. But understand that’s part of why we do experiments to determine what we think is ready to hand-off to soldiers in the field environment.”
Concept to Intercept in Six Months
Perseus’ Harpe micro-missile program has moved rapidly from concept to live-fire testing. Its spin-stabilized rocket motors were developed in June 2025, followed by testing a month later.
By January 2026, it took off for its first-ever fully-guided, direct hit-to-kill intercept of a target.
The company positions the interceptor as a cost-conscious approach to counter-drone defense, with each missile priced at under $10,000 only.
It fires from a pod that can house eight micro-missiles, capable of flying at ranges of 1,000 meters (3,281 feet).
