    Nutella isn't chocolate you fool. It started out as pastries in Northern Italy couldn't import the cocoa they needed and some guy started selling hazelnut paste as a substitute.

    Just like chocolate the hazelnut paste has a lot of magnesium. When you consider that a lot of people are nutritionally deficient in magnesium this anti-chocolate campaign smacks of nothing but ridicule.

    Well it is true in a way. Without sales you cannot pay for anyone in the business. Having helped run a family business for some time I kind of get the point. The quality of the work is important but you would be surprised how many clients don't know any better and in fact how many are dumb enough to believe whatever they're told if the salesperson is impressive enough. Even if they get stiffed by that vendor they may still believe they made a good choice because, let's face it, no one likes admitting they made a mistake.

    As for the Centaur the manufacturing process is quite old fashioned and involves a lot of manual labor. Of course the costs have gone up. For it to be cheaper the engine needed to be redesigned to use modern automated manufacturing methods. They have been working on a replacement for quite some time.

    You have to read the policy paper that came back a couple of years ago. The idea is to increase the power projection capabilities of the US Armed Forces so that in a case of substantial shutting down of US military bases around the world they can strike more or less anywhere they want in the world in a short amount of time. There were moves to use modified Minutemen missiles for this but the Russians were kind of skeptic about it since they claimed you couldn't tell the payload of the missile and they would consider it as if it was a nuclear launch. Even if they have short range missiles that are kind of iffy in themselves like Iskander.

    The Russians have quite a few Mach 3.0 missiles of which they sold a couple to India and to a lesser degree China. As a mainly continental nation they always had this power projection problem to begin with. The article is mistaken as the idea of hypersonic weapons has been around since at least WWII. Read the Wikipedia pages for the Nazi Silbervogel and the US Aerospaceplane. The projects failed at the time as the technological problems were too large to tackle and the materials were not good enough. In fact they may still not be there yet.

    If you want to read about Russian and Indian Mach 3.0 weapons go to the Wikipedia pages for the Moskit and the BrahMos. During the Soviet Union the Russians also had the Spiral spaceplane prototype which was akin to the US Dyna-Soar effort although it progressed a bit further than that one. The Chinese supposedly are drop testing a mini-shuttle similar to the X-37 which people have been calling the Shenlong.

    The F-15 has engines optimized for interdiction so long loiter times at slow speed over the same area were *not* on the design plan. I ask you for a source with actual numbers on loiter time and you give me nothing. The specific fuel consumption on the F-15 engines is a lot higher. 0.76 lb/(lbfh) vs 0.37 lb/(lbfh) on the A-10 engines. Plus the fuel load you are talking about for the F-15 seems like its with external fuel tanks which mean if the airplane gets one shot in them it will just flame up. The F-15 can't do slow low-level altitude passes at the same speeds and still hit a target with the cannon at the same level of accuracy. The plane would stall.

    It actually does. It's a rough ride, but it was designed for a low level penetration into enemy territory. Not that it matters, because neither the A-10 or F-15E will operate at low altitudes.

    Bullshit. The F-15 was designed as an high-altitude interceptor and only later on did they decide to add bombing capabilities to it. It was not designed with low level flight in mind at all.

    That's a funny comment. Take a look at Blue on Blue incidents by the USAF in the past couple conflicts and you might notice a theme. A-10's have shot at a lot of friendlies because they couldn't ID their target properly (and, correspondingly, they've not shot at a lot of bad guys because they couldn't PID). The F-15 with a pod at 35K feet sees way better and way more then an A-10 at 2K feet without one. Which, again, doesn't really matter because A-10's always carry a targeting pod now and hang out at 20K feet. At least the E has a WSO who's job it is to figure out who's who before they start shooting.

    Have you bothered looking at the number of CAS missions each plane has done on those places? The A-10 does a *lot* more missions so of course there are more events like that. In a lot of cases an F-15 won't even bother going there. As for the advantages of dual seat aircraft in a target rich environment they did develop a dual seat A-10 prototype but it was cancelled. You can guess why.

    They're more expensive then you'd think. Depending on how you do the accounting a full magazine of 30mm CM costs between 40K and 80K dollars. There are a lot of hidden costs there to, since proficiency with the gun requires a lot more training time. And there's no gurentee that the gun rounds are going to kill your target. Experience tells that the best way to kill bad guys, regardless of what they're in or where they are, is to drop a whole pile of high explosives on them. Bombs do that quickly and efficiently.

    So a full A-10 magazine costs tens of thousands of dollars and the USAFs much coveted Small Diameter Bomb II costs 250000 dollars *each*.

    As for missing targets with a cannon being useless I guess you have never heard of fire suppression.

    I would like actual facts to back your claim that the F-15 has better loiter time. Plus the F-15 does not handle that well at low altitude flight which regardless of what the Air Force says is important. Sometimes it is not easy to tell the target apart from your own troops and there is a larger time lag to hit the target when you are higher up. Also I bet those cannon rounds are lot cheaper than smart bombs. An important factor to consider when your enemy is using mostly infantry and technicals rather than modern combat vehicles.
