HALO ORION® and GUARDIAN® Automatic Retractable Barrier Systems collapse along their length.

Easy to install and easy to relocate, the ORION® Retractable Defensive Barrier is the little brother to HALO’s GUARDIAN® RDB. ORION is designed as a port security gate against small boat threats and intruders in the marine and nearshore environments.

HALO ORION® Retractable Defensive Barriers are the only automatic port security systems tested by the US Navy and independently verified.

The ORION RDB is a lightweight, rapidly deployable waterside security system. It is used to provide a protective perimeter around valued marine assets, while allowing ease of access for approved operators. ORION is a scaled down version of the GUARDIAN RDB that can be easily positioned in forward locations to protect deployed or visiting assets.


The ORION RDB can be deployed as a static perimeter defense or line of demarcation, or as a dynamic manually or fully automatic gate. The compact design and accordion style compression optimize storage in constrained areas. Barrier systems can be pre-positioned, deployed to protect a visiting vessel, and removed for future use after departure.
