The Challenger is a twin-engine executive jet used in the Canadian Forces both as a medium to long-range transport and also originally as an electronic warfare (EW) training aircraft. Now, based in Ottawa but belonging to 8 Wing Trenton, Ont., the Challenger-equipped 412 Squadron provides high-ranking government officials and foreign dignitaries with air transportation worldwide. Two previous combat support grey Challengers are now assigned to the Squadron, bringing the total to six Challengers in the Canadian Forces. The grey Challengers are used for military transport and can be configured for medical evacuation for CF personnel on duty anywhere in the world. The type was previously used by 434 Combat Support Squadron at 14 Wing Greenwood, N.S. as an EW training and combat support aircraft. In the combat support role, the Challenger was very similar to the CT-133 Silver Star, and EW training involved the same techniques, including chafe radar jamming, the dispersal of false targets to confuse enemy radar, and the creation and transmission of false radar signals. 434 Sqn's Challenger's were also previously employed in the maritime patrol role.
