Bombardier RO-6A
SOCOM Tactical Airborne Multi-Sensor Platforms (STAMP)
The Airborne Reconnaissance Low-Enhanced (ARL-E), designated RO-6A, is the Army’s newest manned multisensor, day and night, all-weather AISR system. ARL-E consists of a modified DHC-8-Q315 fixed-wing aircraft equipped with a reconfigurable payload with enhanced COMINT and IMINT sensors including long-range Ground and Dismounted Moving Target Indicator/Synthetic Aperture Radar high-definition EO/IR FMV, and Hyperspectral Imagery. The sensors are controlled and operated using onboard Distributed Common Ground Station-Army (DCGS-A) multifunction workstations. Intelligence collected on the ARL-E can be analyzed and disseminated in real time; transmitted via Beyond Line of Sight satellite communication; or stored onboard for post-mission analysis.
The more capable DHC-8-Q315 based ARL-E will replace the ARL-M systems (DHC-7) with the First Unit Equipped in Fiscal Year 2020. By leveraging former Quick Reaction Capability DHC-8 programs the Army has capitalized on the reutilization of previous Army investments, non-recurring engineering, improved airworthiness, and improved system availability for the Army ACAT II program of record requirements. There are currently seven ARL-M configured systems and there will be eight ARL-E configured systems and one trainer.
