Would the "new" CF105 be a true multi role type,capable of the mission profiles that the F35 has been designed to undertake?
The original CF105 was,primarily,mooted as a point interceptor,much like the RAF's Lightning which did evolve, in a limited manner,into a ground attack aircraft.
It would be interesting to see what the CF 105 could achieve given the 21st century treatment,perhaps our(UK)government should do the same with TSR-2!

The capabilities of Arrow v0.2 are a question mark as of today, but the basic design is not 'stealth in any way at all. This should be a first step in the re-design.

Overall, I'm for the idea of Bombardier getting involved, which should silence the seperatists in Quebec for about 30 years. It's a win-win for Canadian jobs.

Lewis MacKenzie always was a colourful Major General and, to know he's backing this, makes it all the more interesting.

Correct me if I'm wrong here but weren't most Western jets of the "Delta wing - Century" series very fast with high altitude capabilities meant to engage Russian bombers as far out over the North pole as fast as possible hence their higher altitude capabilities and higher speeds?

Also, was it ever in production and have Vertical take off and landing capability?

Background
In the post-Second World War period, the Soviet Union began developing a capable fleet of long-range bombers with the ability to deliver nuclear weapons across North America and Europe. The main threat was principally from high-speed, high-altitude bombing runs launched from the Soviet Union traveling over the Arctic against military bases, built-up and industrial centres in Canada and the United States. To counter this threat, Western countries strenuously engaged in the development of interceptors that could engage and destroy these bombers before they reached their targets

Every single Canadian high school students was pissed off when Avro was discussed in history class. It being scrapped marked the end of Canadian aeronautics and as well a self-established Canadian made machinery.

To tell the truth, Canada is too nice and people took advantage of that. Then and Now.

I agree with you.

You forgot to mention the stream of aero-engineering experts who, directly as a result of Dief's decision, headed to Florida and NASA to enjoy the surge of interest in the space program. Whether that was intended or not is something to consider.

It would be interesting to look at which Canadian was responsible for what breakthroughs.

With newer, stronger engines and updated avionics, I think there are several retired aircraft out there that could easily outperform the F-35. Let's look at the Lightning's stats:

F-35 Lightning II
- Max Takeoff Weight: 70,000 lbs
- Max Speed: 1,200 mph (Mach 1.67)
- Service Ceiling: 60,000 ft (Theoretically. It's only been tested to 43,000 ft)
- Rate of Climb: Unknown
- (1) 20mm cannon w/ 180 rounds
- (6) external hardpoints
- (2) internal bays w/ 2 pylons each

Now let's look at some of the decommissioned competitors:

F-4 Phantom II
- Max Takeoff Weight: 61,795 lbs
- Max Speed: 1,472 mph (Mach 2.23)
- Service Ceiling: 60,000 ft
- Rate of Climb: 41,300 ft/min
- (9) external hardpoints

A slightly lower maximum weight, but capable of faster speeds and with a fully tested service ceiling. And no stealth capability.

F-14 Tomcat
- Max Takeoff Weight: 74,350 lbs
- Max Speed: 1,544 mph (Mach 2.34)
- Service Ceiling: 50,000 ft
- Rate of Climb: 45,000 ft/min
- (1) 20mm cannon w/ 675 rounds
- (10) external hardpoints

A higher takeoff weight, higher max speed. But lower service ceiling and no stealth capability.

F-111 Aardvark
- Max Takeoff Weight: 100,000 lbs
- Max Speed: 1,650 mph (Mach 2.5)
- Service Ceiling: 66,000 ft
- Climb Rate: 25,890 ft/min
- (1) internal bay w/ 2 pylons
- (8) external hardpoints

The F-111 outperforms the F-35 in every way except for stealth capability and maneuverability.


There are some very capable aircraft in that list,however,why "regenerate" a design from an earlier generation or two,when,despite it's teething troubles,the F-35 has been designed from the outset to embrace the mission profiles that ALL the above mentioned aircraft could perform? plus you state that the F-111 outperforms the F-35 in every way apart from stealth and maneuverability, with it's stealth and hovering/thrust vectoring capabilities,the F-35 surely does outperform the F-111? as outright speed and weapons carrying capability does not neccesarily equate to the optimum platform for certain mission profiles.

Disclaimer: I love the Avro Arrow. I had the wonderful opportunity to work as a restorer in the museum housed in what originally was the place where the Arrow was built in Toronto. I also dislike the F-35 as an aircraft, and believe that the Canadian plan to purchase them is full of holes large enough to sail an aircraft carrier through. I don't think it will do the job that the RCAF will likely need them for, and I think there are aircraft in the world far more suited to what we need. All that being said, I will be very frank about this plan to bring the Arrow back.

The Arrow was a wonderful airframe in its time. It had some truly revolutionary ideas in it to combat some of the enormous challenges that it faced. To a great degree it succeeded in these challenges. The problem it faced at the time was that it was at the trailing edge of the era where nations would use nuclear bombers, and the defense strategy rested on stopping them. Countries were moving forward into the era of guided, nuclear missiles which stood on the shoulders of the space race technologies. As missiles came in, interceptors became obsolete. As a result there is no modern niche which interceptors fit into. Interception has become a secondary mission profile for recent aircraft, and those airframes which were designed for interception in the Cold War have largely been converted to other roles (such as the MiG-31 which seems to be moving into reconnaissance and engagement of high-value airborne assets). If we commission even an improved-capability Arrow it will still be built for a purpose that doesn't really have a place in modern warfare. Effectively, this is going to hamstring it if you try and put it into roles it was never designed for, but which are required in the formula for effective combat.

The other problem is the difficulty of engineering modern techniques into an old airframe. The fact is that the Arrow and its systems were designed with a particular time frame in mind. Available materials, known techniques, and design methods. Half a century of improvements in aerospace are not something you can just stick onto an airplane like a drop tank. The inside of the poor aircraft would have to be completely torn out and redesigned with completely new techniques. Furthermore, I hate to rain on more parades, but the outside of the aircraft would not look the same. Advances in wing design, intake design, and aerodynamics in general would mean that the whole exterior. For those keeping a running tally, that's approximately the entire aircraft that would need a redesign. Let's not even mention the amount of things that would have to go into making sure that the aircraft gets a decrease in RCS.

The third, and potentially most important, of the issues is the who. Who will do the design? Who will build all of the parts? Who will pay for it all? The answers to these questions are not nearly as obvious as they may seem. For the purposes of making an all-Canadian aircraft our choices are few. We have Bombardier and Pratt and Whitney Canada as our aerospace presence. Unfortunately, neither of these companies is prepared or really qualified to head up such a program. Defense aircraft require specific parts which, themselves, require specific design. None of the companies we have in Canada are prepared to undertake designs like that (Bombardier and P&WC doing civil aerospace designs). The cost to get them the appropriate facilities and personnel to do so would make whoever paid for B-2 bombers break into tears.

Do I want to see a flying Avro Arrow? Yes. Do I think it could happen someday? Yes. Do I think the Arrow has a place in modern air combat? Not really. Sorry guys.

I just wonder if the Canadian government under Diefenbaker were coerced into their decision by the US,it certainly appears that Britain's defence review of the same era was driven by US "insistance" that TSR-2 was dropped in favour of the F-111K,which turned out to be a white elephant anyway,but it did give the US time to develop a "lead" in aerosoace technology,if only our respective governments at the time had had the balls to stand up to what amounts to US blackmail,it may well be the likes of AVRO,BAC etc at the forefront today.

PS if it hadn't been for Dennis Bancroft at Miles aircraft in the UK developing the all flying tail,the Bell X1 would not have broken the sound barrier in 1947,unsurprisingly the supersonic aircraft that he and his team were working on ( slated to fly in 1946,taking off under it's own power ,not carried by a B-29) was cancelled and the research "given" to the US government.
