Based on the design adopted by the U.K. MoD, and developed in partnership with wet-winch search and rescue aircrew in Bristow Helicopters, the Alpha 900 Search and Rescue (SAR) Helmet System is the world’s first waterproof rotary wing helmet system optimized for any search and rescue aircrew personnel conducting air-to-sea operations. Leveraging the modern and lightweight design of the Alpha 900 Cross-Platform helmet shell, the Alpha 900 SAR features corrosion-resistant hardware, plus a waterproof and salt-fog resistant communications system to ensure continued performance when exposed to water and spray. Optimised for interfacing to common SAR radios and configurable for all major aircraft intercom systems, the Alpha 900 SAR is the ideal solution for aircrew operating near water.
