01 / 07

Hold the High Ground

A constellation of satellites in Low Earth Orbit, each carrying four miniature interceptors, circles the planet at about 17,500 mph.

02 / 07

Detect the Launch

Onboard sensors pick up the hot plume of a rising missile and begin tracking it during boost phase, while it is slow, bright and has not yet released anything.

03 / 07

Release an Interceptor

The nearest satellite releases one interceptor, which fires its motor and steers toward a predicted intercept point.

04 / 07

Hit-to-Kill

The interceptor strikes the missile body directly and detonates a charge to make sure it is destroyed.

05 / 07

If Decoys Are Released

If the missile has already burned out and released its warhead, it may also release inflatable decoy balloons to confuse defenses.

06 / 07

Tell Warhead from Decoy

Onboard AI compares the motion and signature of each object to separate the real warhead from the decoys.

07 / 07

Clear the Decoys, Take the Warhead

The interceptor dispenses miniature guided kill vehicles that destroy the decoys, while the main interceptor goes for the warhead.

Purpose
and Why

The Problem

Defenses Engage Too Late

Ground-based interceptors usually meet a missile late in its flight, after it may have released decoys. The best moment to stop it is the boost phase, while it is still climbing, but that lasts only minutes and happens far from where ground defenses sit.

The Idea

Interceptors Already Overhead

Satellites in Low Earth Orbit, each with four miniature interceptors, so one is always within reach of a launch. If a missile gets past boost phase, onboard AI separates the warhead from decoys and the interceptor clears both.

Why Stellar

It Is a Launch Problem

A constellation like this needs a large number of satellites launched quickly and replaced often. A reusable rocket flying twice a week at a flat price per kilogram is built for exactly that job.
