context_page_description: The Canadair CT-133 Silver Star is the Canadian license-built version of the Lockheed T-33 jet trainer aircraft, in service from the 1950s to 2005. The Canadian version was powered by the Rolls-Royce Nene 10 turbojet, whereas the Lockheed production used the Allison J33.
context_section_description: The CT-133 entered service in the RCAF as its primary training aircraft for fighter/interceptors. The designation of the Silver Star in the Canadian Forces was CT-133.
  The CT-133's service life in the RCAF (and later the Canadian Forces) was extremely long. One of the more unusual roles it played was as an aerobatic demonstration aircraft, the RCAF's Red Knight. Although the aircraft stopped being used as a trainer in 1976, there were still over 50 aircraft in Canadian Forces inventory in 1995. The youngest of these airframes was then 37 years old and had exceeded its expected life by a factor of 2.5. During this period, the Canadair T-33 was employed in communication, target towing, and enemy simulation.
  The final Canadair Silver Star Mk. 3 was retired from the Aerospace Engineering Test Establishment at CFB Cold Lake, Alberta, Canada, where it was used as an ejection seat testbed after 46 years of service. CT-133 number 133648 was delivered to CFD Mountain View on 26 April 2005. Having been built in March 1959 as a CT-133 with original RCAF serial number 21648, it had reached a total of 11394.6 flight hours at the time of its retirement from military use. It has been sold on the civil market, along with fifteen other CT-133s. These aircraft will join the fifty others on the United States Civil Register and continue to fly as a part of the living legacy of the early jet age.
