Enter the CF18 – the Hornet Flies into Canadian Service
The CF18 entered Canadian operational service in 1984. McDonnell Douglas had flown the first CF aircraft at
St. Louis in July. In October, the first two CF18s were formally handed over to 410 (Operational Training
Unit) Squadron at Cold Lake, Alberta. The CF18 would eventually equip 409, 439, and 421 Squadrons at
Baden Söllingen in Germany, 410 (OTU), 416, and 441 Squadrons at Cold Lake, and 425 and 433 Squadrons at
Bagotville, Quebec. From 1984 to 1990 CF's Air Command operated CF18s in Canada and Europe training
for both the air-to-air combat and ground attack missions. In Canada – in addition to training –
CF18s were tasked directly with NORAD protecting North America from Soviet aerial incursions. [1]
But, the CF18's entry into service hadn't been completely without pain. Structural fatigue problems
plagued the early CF18 [2] and delayed their deployment. It had been intended that the first operational
squadron would perform NORAD duties but, in the end, 409 Squadron had to be redeployed to Baden-Söllingen.
Once its structural problems had been overcome, the CF18s began to fill both the NATO and NORAD roles as
originally planned.
The new CF18 pilots would prove to be very capable aerial marksmen. In 1988, the CF team at the reknown
international William Tell air-to-air weapons competition came a strong second to the top US team.
Further opportunities to fly in mock air- to-air engagements against NATO fighters were available to CF18
pilots assigned to the 1st Canadian Air Division (1CAD) in Europe. During this period, the pilots of
CF18s averaged 240 flying hours per year enabling them to maintain very high levels of proficiency. Some
indication of the aggressiveness of their training is provided by the fairly high CF18 attrition rates during
the period.
Nevertheless, CF18 training attrition was actually lower than had been anticipated in initial procurement
planning. In 1985, this lower than expected training attrition rate (and the usual funding
limitations) prompted Canada to decline the option it held on an additional 20 CF18s at their original
1978 purchase price. This decision would come back to haunt DND, particularly as the flying hours began
to mount on aging CF18s. When it was time to modernize, the
CF18 fleet had to be culled.

[1] The CF18 soon proved itself in this role, intercepting Soviet bombers as they approached North
American airspace. Col Chris Hadfield (later to become the first Canadian to walk in space) flew the first
CF18 interception of a Soviet Tu-95 Bear bomber off Canada's East Coast when Hadfield was serving
with 425 Squadron.
[2] Fatigue cracking was traced to excessive loads placed on the twin tails by the vortices streaming
from the large wing leading-edge extensions (LEX). In the end, the fix was relatively simple. A somewhat
crude cast-aluminum 'fence' was fitted to each LEX to modify the vortex pattern and alleviate the
stress on the tailplane.
