 Along with the 3 new Dauphin helicopters, the Squirrel was also replaced with a new twin-engined Eurocopter EC135 T2+ that fulfilled the same role.The two engines of the EC135 meant it was able to safely operate over urban areas where the single-engined Squirrel was limited or excluded.While the new aircraft had much greater capabilities over the previous generation, such as HD Forward looking infrared (FLIR), LogiMap moving map software and Night Vision Goggles (NVG), the new aircraft were also significantly quieter, an important feature when operating over urban areas.
