The lines are coming together for SSTO. A little luck in the Polywell arena, and we may have a winner.
This also seems to be a good use for rockets...

That's called the "historian's mistake". Plainly we didn't need the Arrow, since we didn't have it and we're still here.choff wrote:So, we needed a mach 2.5 interceptor to catch a turboprop bomber,
I never said that. Though I believe there was interest from other countries (not everyone was building their own interceptors at the time), and even some interest from south of the border...and other countries that wanted to export their aircraft would just scrap production and buy ours.
No, that was the government being cheap. Our national debt didn't start ballooning until later, and it wasn't for military reasons. Not that I'm against conserving paper...I've talked to guys in the service in the 60's who told me they had to make sure too use up both sides of writing paper to control stationery costs. That was the legacy of expensive projects.
What's that got to do with the Arrow?Another boondoggle was the CANDU reactor exports, practically bribing other countries to purchase nuclear plants and build up market share. That's one of the reasons India and Pakistan are in a nuke standoff.
I know this very well; I'm from Alberta. How is it relevant to the question of whether or not the Arrow was a good idea? It's not like there was a Saskatoon-based aeronautics firm with a superior bid...Ontario and Quebec believed in a model of Canada where the other 8 provinces were the hinterland, providing the raw material and captive home market while they kept the big ticket manufacturing jobs and created a huge high tech market for themselves overseas, it was a crock.
No, the Canadian government was convinced at the time that the age of missiles was upon us, and that manned interceptors were about to become entirely obsolete. Immediately after cancelling the Arrow, they found out that this wasn't true, and that the defence of Canada required interceptors - but nothing was done at that time, in order to avoid political embarrassment.choff wrote:About ten years ago a major magazine ran an article on declassified U2 recon photo's. Only 20 people in the U.S. including Eisenhower had access to these photos in the late 50's early 60's, and what they showed is that the Soviet bomber threat was a colossal bluff. That's why XF106 Rapier got nixed, and that's probably why the CF105 got the axe after Eisenhower went on a fishing trip with then Canadian prime minister Diefenbaker.
The Arrow was designed for long-range supersonic interception missions (hence the supercruise) and supersonic combat with bombers; hence the stringent maneuverability requirement of 2 gees at Mach 1.5 and 50,000 ft while maintaining speed and altitude (<12 km turning radius IMCAC, or obviously a lot less if you were willing to trade speed and/or altitude; note that neither the Tu-95 nor the Tu-22M could fly as high as the Arrow). You didn't have to do a flyby and show the bomber crew a centerfold if there were hundreds of the things headed straight for your bases and major cities....As pointed out, pilots can't dogfight at mach 2.5 because they can't see each other to do it.
The ALCM (AGM-86A) and Tomahawk have ranges of 1500 nautical miles. The Stealth ALCM (AGM-129A) has a range of 2000 nautical miles. There are shorter range models that perform specific missions, like conventional warhead bunkerbusting, etc.kunkmiester wrote:Cruise missiles can have a range of well over a thousand miles, and generally at least 500 for the big ones. You generally want to get to the bomber BEFORE it launches, so you only have to use a couple of missiles to blow up the bomber, and not dozens to shoot down the 12+ missiles after they've been launched.
So you want enough speed to get out, blow up the bomber, come back and rearm to catch the next wave or shoot down some missiles or something. You need a lot of range and speed to make that possible, even with a turboprop bomber.
Not all of them...IntLibber wrote:Despite their greater size, soviet cruise missiles are much shorter range than American models.
Yeah, thats the Tomahawk clone, or near clone. Another good example (along with the F-15/Mig-25) of how similar mission parameters result in nearly identical design solutions.93143 wrote:Not all of them...IntLibber wrote:Despite their greater size, soviet cruise missiles are much shorter range than American models.
Really? I thought is was called espionage and "reverse engineering"! Can you say "Concordski"? "Shuttleski"?IntLibber wrote: Yeah, thats the Tomahawk clone, or near clone. Another good example (along with the F-15/Mig-25) of how similar mission parameters result in nearly identical design solutions.
