Michael Byers and Stewart Webb report on the latest technical glitch to be reported in the F-35 development:
The ability of F-35s to avoid radar detection depends on a “fibre mat,” which is cured into the composite surfaces of the aircraft.
In December 2011, a test version of the F-35 for the first time achieved the design speed of Mach 1.6. According to Bill Sweetman of Aviation Week, the flight caused “peeling and bubbling” of the stealth coating on the horizontal tails and damage to the engine’s thermal panels, and the entire test fleet was subsequently limited to Mach 1.0.
Repairing and replacing stealth materials is a time- and technology-intensive process that reduces the “mission capable rate” of aircraft. Indeed, it has been reported by the U.S. Congressional Research Service that after five years of service the F-35’s sister plane, the F-22, has a mission capable rate of just 60%.
And then they touch on the issue that has been lurking below the surface for a while, regarding the small number of aircraft the RCAF will be able to afford (assuming the government goes through with the F-35 purchase):
If the F-35 has a similar mission capable rate, Canada will, at any given time, only be able to deploy approximately 44 of its planned 65 planes. When attrition through accidents is factored in — and Canada has lost 18 of its CF-18s since 1982 — we could soon have an available fleet of just 30-35 planes, or roughly half of what the Department of National Defence says we need.
That might be the crucial point on which the F-35 acquisition fails: no matter how good the aircraft are (and I believe they will eventually work through and fix all the major issues), we can’t afford enough of them. Even without taking on new missions, we need a certain minimum number of aircraft, and I thought 65 was low-balling that number. The alternatives are to buy some F-35’s and a larger number of less expensive planes like the Super Hornet, or skip the F-35 altogether and just buy a different aircraft. The problem with splitting the order is that what we’d save on reduced F-35 acquisition costs, we’d more than lose because the RCAF would have to maintain duplicate maintenance and training programs. Unlike the RAF or the USAF, the RCAF isn’t big enough to fly multiple models on an ongoing basis (and you know that the government can’t and won’t fund a larger air force budget).
