Group 1 / FPV & fiber-optic UAS

BlueJay

A man-portable, canister-launched interceptor for Group 1 FPV and fiber-optic-controlled UAS. Radar-agnostic, it supports three guidance modes and fully autonomous operation in GPS-available or GPS-denied conditions using XCaliber’s proprietary encrypted terminal guidance.

Group 2/3 & one-way attack UAS

Starling

A vertically canister-launched interceptor designed for Group 2 and Group 3 UAS and jet-powered one-way attack threats such as Geran-5. Designed to exceed 500 km/h with a 5 km range, it autonomously coordinates with other launched Starlings through MOSES.

Group 4/5 UAS / Reusable fuselage

Falcon

FALCON is a modular interceptor concept with detachable payloads and a reusable fuselage, designed for precision and scalable drone defense. Planned for ground, air, and maritime launch, it targets Group 4 and 5 UAS. Its design calls for speeds exceeding 1,000 km/h and a 20 km operating range. The system is currently under development.

Phoenix

PHOENIX is XCaliber’s molecular-laser directed-energy system designed to neutralize Group 1, 2, and 3 drones at ranges up to 2 km. Built for vehicle-mounted or fixed-site defense, it can be installed on military platforms such as a HMMWV or at fixed installations as part of a layered counter-UAS response. Laboratory testing is complete, and development is now focused on assembling and integrating the field-deployable system.

MOSES.TM

Mechanically Operated Self-Empowered System

The C4 intelligence layer linking sensing, decision support, and coordinated response across the counter-UAS mission.

MOSES interface visualization showing sensor feeds, a common operating picture, and EO/IR views
One common operating picture

MOSES brings radar, EO/IR, passive RF, acoustic, and other sensor feeds into a common operating picture. It maintains tracks, identifies and prioritizes threats, recommends or assigns responses under operator-defined rules of engagement, and uses sensor feedback to assess outcomes and support re-engagement.

01 / DETECT

Layered, sensor-agnostic sensing

Ingests commercial and military radar, EO/IR, passive RF, acoustic, and future sensor inputs, with support for third-party C2 networks.

02 / TRACK

One operating picture

Fuses inputs into continuous tracks, reduces duplicate targets, and maintains track quality across the defended area.

03 / IDENTIFY

AI-assisted threat assessment

Classifies and prioritizes aerial objects, distinguishing threats from friendly, neutral, and non-threatening activity.

04 / ENGAGE

Coordinated response

Recommends or assigns monitoring, alerts, or interceptors under operator-defined rules of engagement, with human-in-the-loop or human-on-the-loop oversight.

05 / NEUTRALIZE

Layered defensive effectors

Designed to coordinate BlueJay, Starling, and Falcon interceptors alongside PHOENIX directed energy once an engagement is authorized.

06 / ASSESS

Assess and re-engage

Uses sensor feedback to assess the result, update tracks, reallocate effectors if needed, and record outcomes for review.

XCaliber Technologies United States flag

One system.
Multiple intercept layers.

Our core team brings together experience in military and intelligence missions, federal law enforcement, AI and advanced engineering, cybersecurity, business strategy, and defense compliance.

We develop connected counter-UAS systems that pair sensing and decision support with our proprietary low-cost autonomous interceptors.

Our approach is modular: bring the right sensors, command layer, and response to each mission. BlueJay and Starling are the lead interceptor platforms; Falcon extends the interceptor layer, and PHOENIX adds directed energy.

04 / Build with XCaliber

Build what
matters.

Work on defense systems that move from the bench to the field. At XCaliber, the people who design the hardware also help build it, test it, and make it better.

Build. Test.
Prove it.

Join a team tackling real counter-UAS challenges across robotics, autonomy, integration, and flight testing. Bring your judgment, work with your hands, and own the result.
