Blue Ring is a multi-role upper stage, orbital tug, rideshare adapter, and satellite platform under development by Blue Origin. It is primarily intended for use with their New Glenn rocket, but is compatible with a range of medium/heavy-lift rockets offered by other providers as well
Structurally, Blue Ring is built around an ESPA (EELV Secondary Payload Adapter) compatible rideshare adapter, with twelve 24-inch radial ports and one wider primary port, each of which can support a deployable or hosted payload. The service section supports two Roll-Out Solar Arrays, and a hybrid propulsion system composed of three electric propulsion thrusters and one chemical engine
Model includes a set of notional satellites and hosted payloads. Solar arrays and the communications antenna are articulated. Modifiers and instancing have been used to reduce file size and simplify editing.
