Design and Development
Originally designed by Northrop as a low-cost, disposable, low-maintenance fighter jet, the F-5 was intended for use by air forces that had limited resources and technical expertise to maintain a sophisticated aircraft. For Canada, which had an extensive aerospace industry, selection of the F-5 was seen as a step backwards. Selected originally to provide a tactical support role based in Canada, the CF-5 was also committed to NATO's northern flank to act a rapid-deployment force. However, the role for the CF-5 throughout its service with the RCAF was changed frequently and eventually, the diminutive fighter would serve as a light attack strike fighter, reconnaissance platform and trainer.
The Canadian version had several modifications to make it more suitable to operating in Canadian Forces theaters of operations. In order to address complaints about long take-off runs, the Canadair version featured a two-position nose landing gear; compressed it operated like the original, but extended (before takeoff) it raised the nose and thereby increased the angle of attack and increased lift. The system reduced takeoff distance by almost 20%. A mid-air refueling probe was installed, Orenda built General Electric J85-15 engines with 4,300 lbf (19 kN) thrust were used, and a more sophisticated navigation system was added. The nose of the CF-5 was also interchangeable with a specially designed reconnaissance set with four cameras in it. Over the course of its life, it received many upgrades to its avionics and capabilities.

Famous quotes containing the words design and/or development:
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
