Persistent threat requiring autonomous, always-on defense

A $500 drone shouldn't require a $2M missile.

Small UAS have transformed modern warfare. Swarm attacks, kamikaze drones, and ISR platforms are proliferating faster than legacy air defense systems can adapt.

Traditional kinetic and electronic warfare solutions are either too expensive per engagement, too slow to react, or create unacceptable collateral damage. The economics are broken.

SENTINEL restores the cost advantage to the defender.

The Economics of Asymmetric Air Defense: Why Cost-Per-Engagement Decides Wars

Modern conflicts have exposed a fundamental flaw in legacy air defense economics. When a defending nation expends a missile costing hundreds of thousands of dollars to neutralize a commercially available drone costing a few hundred, the attacker wins the economic war regardless of the tactical outcome.

This cost asymmetry is not a marginal issue — it is an existential strategic challenge. A sustained drone campaign of 100 daily sorties forces the defender to burn through its interceptor stockpile at an unsustainable rate, creating windows of vulnerability that adversaries can exploit with higher-end assets.

The solution is not incremental improvement of existing systems. It requires a fundamentally different class of interceptor — one that costs less than the target it destroys, can be manufactured at scale, and operates autonomously to match the volume and tempo of swarm attacks.

  • A single SENTINEL battery provides 24 autonomous engagements at $6,900 each — total expenditure of $165,600
  • The same budget buys less than one engagement from most legacy kinetic systems
  • Pneumatic cold-launch eliminates propellant logistics — no fuel, no exhaust, no thermal launch signature
  • AI-guided terminal phase with LWIR seeker operates in GPS-denied and EW-contested environments

Human-on-the-Loop: Autonomous Defense Without Autonomous Killing

The debate around autonomous weapons often presents a false binary: full human control versus fully autonomous systems. The human-on-the-loop architecture offers a third path that preserves human decision authority while enabling the reaction speeds required to counter drone swarms.

In this model, the human operator authorizes each engagement on a digital battle map. Once authorized, the interceptor executes its terminal guidance autonomously — the AI handles the microsecond-level maneuvering that no human operator could perform manually. The operator retains abort authority throughout the engagement.

  • Authorization latency under 1 second from track classification to launch clearance
  • Operator maintains abort authority through encrypted data link
  • AI handles only terminal guidance — not target selection or engagement decisions
  • Compliant with emerging international frameworks on autonomous weapon systems
Technology

LWIR Seekers vs. Electronic Warfare: Why Passive Guidance Wins

Electronic warfare has emerged as the first line of defense against drones, but sophisticated adversaries are rapidly developing EW-hardened platforms. GPS spoofing, RF jamming, and communication disruption are increasingly ineffective against autonomous drones that navigate by inertial guidance or visual odometry.

Passive infrared seekers operate on a fundamentally different principle. Every powered drone emits heat — from its motors, batteries, and electronic components. An LWIR seeker tracks this thermal signature without emitting any detectable signal, making it immune to RF jamming and resistant to the countermeasures that defeat radar-guided interceptors.

  • Zero emissions — the seeker cannot be detected, jammed, or spoofed
  • Effective in all weather conditions, day and night operations
  • Thermal signatures cannot be fully suppressed on battery-powered drones
  • Works in GPS-denied environments where RF-guided systems fail
