of time, starting development in 1953, completing it in May 1954 and building and running the prototype by
December 1954. During the testing period, the Iroquois was the most powerful jet engine in the world, rated at 19,250 lbf (85.6 kN) dry, 25,000 lbf (110 kN) afterburning. It was aerodynamically matched for peak performance at 50,000 feet (15,000 m) altitude and Mach 2 speed. After some 7,000 hours of development testing, up to a simulated altitude of 70,000 feet (21,000 m) and a forward speed of Mach 2.3, the Iroquois program was cancelled, along with the Arrow on 20 February 1959.

When it entered production it was the most powerful engine in the world, a title it held until 1952. Almost 4,000 Orenda engines of various versions were built by the time the final unit was delivered to the RCAF in July 1958.

Over the next few years they aggressively expanded by purchasing a number of Canadian aerospace companies, including Orenda, which they renamed as Orenda Aerospace, now Magellan Repair, Overhaul & Industrial.

Work on the TR.4, the first
Canadian-designed jet engine, continued. Now called the Chinook, it first ran in March 1948, producing 2,600 lbf (12,000 N) thrust. Only three were built before all attention moved to the Orenda.

September 1963, the last in October 1965. Production of a derivative engine, the afterburning J85-CAN-15, began in 1967 when Canadair was licensed to produce the

In 1955, another reorganization led to the creation of Orenda
Engines. Avro Canada would later disappear due to the cancellation of the Arrow, but Orenda had a major engine overhaul business that allowed them to survive.

The Orenda's design was similar enough to the
Chinook that prototype production was completed in less than a year, and the engine first ran in February 1949. Testing proceeded quickly at a facility outside
