SkyAlyne confirms that the first CT-153 Juno underwent final Government of Canada acceptance at Southport and ownership transferred to the RCAF. This is stronger evidence than physical arrival alone, while student training under the complete FAcT system remains a later milestone. SkyAlyne is KF Aerospace and CAE’s training joint venture.

KF Aerospace acquired the CT-153 Juno fleet for SkyAlyne, its joint venture with CAE, and provides engineering, airworthiness and Southport site support. The first Juno arrived for FAcT training development and train-the-trainers work; Canadian Helicopters provides maintenance and rotary-wing programme support. Eighteen further aircraft deliveries are planned through 2028.
