2007 · Twin-engine medium turbine helicopter

History News
By 2007 it was looking like the CHF Sea King HC.4 would be called on to operate in Afghanistan in support of Operation Herrick. Changes were needed to allow the airframes to better cope with the hot, high and dusty conditions in theatre and during late 2007, a modification programme commenced. These included new composite Carson main rotors, a set of new 5 bladed tail rotors, NVG compatibility upgrades in the cockpit, and a decoy and defensive aids fit.
