The Canadair CT-133 Silver Star (company model number CL-30) 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, instead of the original Allison J33.

The Canadair CT-133 was the result of a 1951 contract to build T-33 Shooting Star trainers for the Royal Canadian Air Force (RCAF) with a Rolls-Royce Nene 10 turbojet.

One of the more unusual roles it played was as an aerobatic demonstration aircraft, the RCAF's Red Knight.

3 was retired from the Aerospace Engineering Test Establishment at CFB Cold Lake, Alberta, where it was used as an ejection seat testbed for 46 years,[3] when it was sold as surplus on the civil market, with fifteen other CT-133s to join fifty others on the US Civil Register.
