MH-47G Chinook

The MH-47G, 'Gulf' model Chinook is an improved MH-47E helicopter and is flown exclusively by the US Army's 160th Special Operations Aviation Regiment (SOAR).

The MH-47G carries out overt/covert infiltration, exfiltration, air assault, resupply and sling-load operations ins support of special operations forces.

Improvements to the ageing 'Echo' model include a new cockpit, extended nose and a host of avionics upgrades. The updated avionics gear includes the US Army's Common Avionics Architecture System (CAAS) - set of standardized LCD screens, communications devices and data processing units. The displays of a CAAS-equipped helicopter can combine data from all of the onboard sensors to suit the needs of the mission. CAAS can also integrate sensor data from external sources such as JSTAR airborne radars, weather radars and other sources, thus greatly enhancing their navigational ability and situational awareness. The MH-47G's multi-mode radar provides terrain avoidance data to a moving map display in the cockpit. Mission-planning software and a set of automated-flight aids allows the crew to plan routes on-the-fly based on changing fuel, cargo and mission requirements.

The current fleet of MH-47D and MH-47Es within the 160th SOAR are in the process of being replaced by the new MH-47G. The first MH-47G was deployed to Afghanistan in March 2007.
