The problem of the timely delivery of an operational F-35
arose seven years ago. The Conservative
government of Stephen Harper, with Defence Minister Peter MacKay, wanted to
sole-source a purchase of F-35s from Lockheed-Martin, but could not close the
deal because an operational aircraft simply could not be delivered. Meanwhile, the operational end of the current
fleet of CF-18s was getting closer.
The Harper government was offered a proposal that would see
the redevelopment the CF-105 Avro Arrow as an alternative to the purchase of an
aircraft that may never be delivered because of decisions made by the U.S.
congress. This offer was not taken
seriously by the government, and dismissed with the argument that the Arrow was
“1950’s technology.” At the election of
2015, the Trudeau Liberals promised never to buy the F-35, if it ever became
available, and would instead hold a competition to replace the aging CF-18s.
Time passed, and the Liberal government just this year got
around to starting that competition. The
first new replacements for the CF-18s are not expected to be delivered until
2025, and to fill the operational gap the government resorted to purchasing
aging F-18s from Australia.
If Canada had a fleet of fighter aircraft that could reach
70,000 feet altitude in level flight at a speed of Mach 2.3, a wing-loading of
under 50 lbs/sq. ft., thrust-to-weight ratio of 1, and had a long combat
radius, nobody would be laughing. Yet,
that was the design performance of the Avro Arrow. The Orenda Iroquois engines, those developed
especially for the Arrow, were successfully wind-tunnel tested at that altitude
and speed, and the big Arrow carried a lot of internal fuel. In speed, range, and altitude, that aircraft
would outperform any modern fighter, including the F-22 Raptor. It could intercept a U-2 spy plane at altitude,
and any bomber aircraft in the world, then or now, except perhaps the
exceptional XB-70.
Where fighter technology has developed since the 1950s is in
avionics, in turning capability, and more recently, stealth. The F-15 Eagle and
the F-16 Fighting Falcon pioneered 9 g
turning capability, and the sub-sonic F-117 Nighthawk pioneered stealth. The F-22 incorporated these developments into
one aircraft, and the F-35 is supposed to be the next generation of avionics.
The characteristic that distinguishes one aircraft from
another is its airframe. Not its
engines, not its avionics, as both of these can be changed or improved without
anyone saying it was a different aircraft.
A Boeing 747 is still a 747 regardless of whether its engines come from
Rolls-Royce, Pratt & Whitney, or GE.
If avionics are changed, or its body stretched, then we might say it is
a Mark II, a Block 15, or a J-model of that aircraft, not that it is a
different aircraft. Hence, it is
disingenuous to dismiss out of hand the Arrow as “1950s technology.”
If Bombardier were commissioned to make the Arrow airframe,
and that airframe were powered by the same Pratt & Whitney engines that drive
the F-22 Raptor, and an appropriate avionics and missile package were purchased
from Lockheed-Martin or Boeing, then suddenly this aircraft would be a very
modern fighter-interceptor. It would be
lacking in stealth, like the F-15. The
airframe may have to be strengthened to handle high-g turns, if dogfighting were one of its expected missions. But it would be as much a modern platform as
the F-35 is, except better in terms of flying performance. A modern improvement of the Arrow package
could be the incorporation of vectored thrust.
If the F-35 is protected from dogfighting on account of its
stealth, the Arrow would be protected on account of its speed and
altitude. “Look-down, shoot-down” radars
at an altitude of 70,000 ft. would detect “stealthy” aircraft flying far below,
and the outcome of that battle would depend upon who had the superior
situational awareness and missile performance.
As an Australian politician observed, the F-35 should be
called the A-35, since it is more designed for ground attack than fighting the
air superiority battle. Risking an
aircraft that costs $200 million to fire multi-million dollar missiles at
targets that cost but a few thousand dollars is sensible to a country that has
the vast economic resources of the United States. But to a country like Canada, it
doesn’t. It would make much more economic
sense for a country like Canada to use a cheaper aircraft and cheaper
technology for that role, like, say, the A-10 Warthog with its 30 mm Gatling
gun, or a Super-Tucano.
We are confronted with the fundamental absurdity of the
F-35. A multi-role aircraft is not
stellar at any one thing, and you bear the cost of multi-role all the time,
even when you executing just one of them.
The F-35 is like a Lamborghini SUV: are you really going to get it muddy? Are you going to risk busting an axle rooting
around in the back country with one?
An Arrow built today is not “1950’s technology.” It would be highly capable of performing the
primary and traditional missions of the RCAF: high altitude interception and
winning the air superiority battle. If
the government is prepared to spend $16 billion to acquire a new fighter seven
years from now and develop the Canadian aircraft industry at the same time, it
ought to brook the professional conservativism of the RCAF brass and examine seriously
the proposal of redeveloping Canada’s most famous still-can-do.
