Orenda Engines Limited - Orenda Iroquois

The Orenda Iroquois turbojet integrates stealth capabilities, as super cruise is essentially super sonic speeds without afterburner, and has a much cooler exhaust.

The use of a twin engine aircraft design of the Arrow, generates tremendous gravity defying thrust, and higher speeds effortlessly with the high performance capabilities required for successful mission tasking, which is the interception and destruction of targets.

The Orenda Iroquois engine success is made possible with the Altitude Test Facility and a magnitude of aero engineering work, materials science and production and combustion thermo-physics. It has the record for the longest continuous run time in full after-burner of 1,000 hours, which is more than enough to prove the point.
