VESPID: The Interceptor Legacy Systems Couldn’t Build

At a glance:

• Autonomous interceptor for Group 1-3 drones, built at up to 90% lower cost than legacy SRM/turbojet systems
• Launches in under 5 seconds; intercepts out to 10 km under 100 seconds
• Radar-guided, GPS-independent, fire-and-forget terminal engagement
• Man-portable and assembled in under a minute, scalable to a 100+ round containerized launcher

The drone threat has changed faster than the systems built to stop it. Group 1-3 unmanned aircraft, cheap, fast, and increasingly weaponized, are forcing a rethink of what effective air defense actually requires. Legacy interceptors, often adapted from solid rocket motor or turbojet architectures, were built for a different threat environment: fewer targets, slower timelines, and a much higher cost tolerance per engagement.

That mismatch is the problem VESPID is built to solve.

A Different Kind of Interceptor

VESPID is a low SWaP-C (size, weight, power, cost) UAS interceptor designed for rapid, autonomous engagement of Group 1-3 drone threats. It's built on an Electric Ducted Fan (EDF) propulsion system paired with commercial off-the-shelf drone market electronics, an architecture choice that fundamentally changes the cost and logistics equation. There's no solid rocket motor, no turbojet, and no energetics to install, ship, or clear after use. The result is a sub-12 lb system that reduces cost by as much as 90% compared to traditional SRM and turbojet interceptors.

That cost reduction isn't just a procurement win. It changes what's operationally possible: a force can field VESPID in the volume that modern drone threats actually demand, rather than rationing a small number of expensive interceptors against a growing number of cheap ones.

Built for the Engagement Window That Actually Exists

Fast-moving drone threats don't leave room for long decision cycles. VESPID launches in under 5 seconds since it doesn’t need to spin up a turbojet and engages targets out to 10 km in under 100 seconds total, a timeline built specifically around the realities of Group 3 UAS behavior (to include turbojet-based UAS), not adapted from a legacy missile system. VESPID is highly maneuverable owing to thrust vector control (TVC) and high performance EDF engine, creating a lethal hit-to-kill punch even for targets trying to evade intercept.

Mid-course guidance comes from CHAOS radars or an external Command and Control (C2) system, reducing the seeker's search volume and complexity while improving resistance to jamming through a direct-to-radar datalink. One no longer needs to rely on separate COTS datalink terminals and antennas. It’s all seamlessly combined in an easy-to-use package previously obtainable via high priced monolithic systems. Integration with NEXUS, CHAOS's in-house C2 system, enables coordinated swarm response, and the system can interoperate with existing C2 architectures rather than requiring a standalone ecosystem. When paired with a CHAOS radar, the system also utilizes the interceptor datalink signal as a beacon, allowing NEXUS to precisely identify friend vs foe.

In the terminal phase, VESPID shifts to a COTS long-wave infrared (LWIR) seeker with AI-enabled acquisition and guidance. No operator input is required after launch, and there's no GPS dependency, a deliberate design choice given how routinely GPS-reliant systems are being jammed and spoofed in contested environments today.

Designed to Move With the Force It Protects

VESPID's Mk.0 configuration is built around minimal logistics: man-portable, deployable in austere environments, and assembled into a complete interceptor in under a minute without special tools. It ships without battery or wing installed for high-density transport, and launches vertically via its EDF propulsion, eliminating the special handling provisions that solid rocket motors or turbojets require. It can be launched from the ground or a truck bed.

The Mk.1 configuration scales that same approach: a high-density tubular launcher using a pyrotechnic cartridge, available now as a 10-round trainable launcher, with a path to a 100+ round, 20-foot ISO container launcher for unmanned ground or surface vehicle integration. Engagement velocity reaches 150 m/s (300+ mph), with a fast start and fast climb to altitude.

Both configurations share VESPID's hit-to-kill design: no energetics to install, ship, or clear post-use, simplifying logistics at every stage from storage to disposal.

Why This Matters Now

The counter-drone market has no shortage of entrants right now, spanning legacy primes, European and international manufacturers, and a wave of newer companies building everything from COTS-derived interceptors to adapted designs drawn from recent conflict zones. What distinguishes an effective answer to this threat isn't any single capability in isolation, it's whether a system is affordable enough to field at the scale the threat demands, fast enough to matter against targets that close distance in seconds, resilient against jamming and GPS denial, and light enough to deploy with minimal training and logistics burden.

VESPID was built around that full set of requirements simultaneously, rather than optimizing for one dimension at the expense of the others. It's an interceptor designed not around what was easiest to adapt from existing missile architecture, but around what the current and future threat environment actually requires.

Closing the Gap

VESPID represents a different approach to counter-drone defense, one built around cost, speed, and autonomy from the ground up, rather than adapted from legacy missile architecture. By pairing a low-cost airframe with radar-guided, GPS-independent targeting, VESPID gives forces the ability to field meaningful counter-drone capability at the scale the current threat requires.

That's the gap legacy interceptors weren't built to close.
