Applications

Patrol

Persistent Presence:
Maintain a continuous operational presence in orbit, ready to reposition and respond as mission priorities evolve.

Space Superiority:
Rapidly maneuver to safeguard critical space assets, deter adversary activity, and support resilient orbital operations.

Hosted Payloads:
Carry surveillance, sensing, and mission-specific payloads to extend awareness and provide actionable intelligence on orbit.

Responsive Mobility:
Execute high-thrust orbital transfers that enable rapid repositioning, intercept missions, and sustained operations across multiple orbital regimes.
