This is a spherical, manned SDP acting as a major planetary defense installation. It is well protected by armor and force screens, heavily armed, and equipped with an operations center for battle management of other defensive assets (other SDPs, ships, etc.). Its 10,000-ton (SM +10) unstreamlined hull is 45 meters in diameter.

This battle station now provides the main close in defense for all major systems, having almost totally replaced warden in the role
