HDT Storm is a multi-purpose search and rescue tactical vehicle (SRTV) designed and manufactured by HDT Global, for the US Air Force (USAF). The vehicle in USAF service is designated as Guardian Angel Air-Deployable Rescue Vehicle (GAARV).
The vehicle is deployed to assist the USAF’s Combat Search and Rescue (CSAR) units in personnel recovery missions. It can quickly transport personnel into the battlefield to provide superior mobile rescue capability.
The air deployable recovery vehicle can also perform disaster relief and other humanitarian assistance operations. It has a high cargo capacity to carry medical and rescue equipment.
Orders and deliveries of HDT Storm SRTV
HDT Storm SRTV was unveiled at the Modern Day Marine exhibition held in September 2012.
HDT Global’s Expeditionary Systems Group (ESG) secured a Guardian Angel Air-Deployable Rescue Vehicle (GAARV) contract from the Air Force Life Cycle Management Center (AFLCMC) to manufacture the Storm vehicle in January 2013. Production of the vehicle began in August 2013.
The USAF received first set of GAARV vehicles in November 2013. The vehicles provide enhanced capabilities to the Guardian Angel rescue teams of the 88th Test and Evaluations Squadron (TES) Guardian Angel Test Division to search for and recover individuals in difficult geographic locations.
The GAARV is being tested to evaluate its effectiveness and compatibility with Guardian Angel, which is the USAF’s non-aircraft weapon system.
