Well, despite this message:I think that a new topic is unnecessary, as my post is completely in line of the already existing topic. Therefore, please forgive me for bumping this back to the front page. B) :-\Well, on topic!Seeing this concept, and after reading it's history (both the true events as well as the "What might have happened part") from Zack Parson's "Final Book" I have given this thing some thought.As mentioned on various forums and other websites, this thing is almost certainly too big and heavy to be of use. Good thing Speer cancelled it. Well, for Nazi Germany at least. In a historical context it might have been better if they did finish three of these monsters, as it would have depleted their resources and wasted man power which would have helped end the war a year or two earlier.*WE WILL RETURN AFTER THESE MESSAGES*==================================*WE'RE BACK, READY FOR ROUND TWO!!*Sorry about that, my Modem needed to be rebooted.As I was saying, the P. 1000 Ratter and the P. 1500 Monster are unpractical designs, despite how attractive they might seem at first. A bit like the giant walking Viggers/Centinental HWR-00 Monster Mk II Heavy Weight Robot from the Japanese anime Macross. It looks good and effective on the show, but it's a slow walking 24 meter tall, 40 meter long giant. Might just as well been painted red with a big sign "shoot me" on top. I still love the design though, and some smaller walking armor / vehicles might not be totally out of the question, despite the fact that they would look nothing like this, or like any of the other Manga/anime shows.However, I think there's a way to put a big Naval gun on a land mobile vehicle. And the answer to that is this:Yup, an Electromagnetic Rail gun from BAE. Read the article, it's very interesting! Imagine, a 15 kg projectile (lighter than standard tank ammunition) flying towards the target with a speed of Mach 7 (ca. 8,568 km/h or 5,324 mph) over a distance of about 500 km (310 miles) and still hit the target with a speed of Mach 5 (ca. 6,120 km/h or 3,803 mph). No matter what kind of armor you have, nothing will protect you against that! You won't even need explosives, the speed and shockwave alone would be devastating enough.Of course the gun needs a huge power source, but surely this will be developed in the next couple of decades. After all, we can now build a laser inside a Boeing 747. A rail gun of 32 MegaJoule mounted on a big tank-like vehicle should also be possible in the future. Because ultra-thick armor is getting more obsolete these days, and speed and mobility are more important, a lighter vehicle, say 300 metric tons maximum (yes, still over three times the weight of the heaviest tanks around) should be possible. The size of the vehicle would also be smaller than the P. 1000 but still large, say about 20 meters long. Powerful gasturbines or the latest issue diesel engines could be used to power it. The gun itself could use some kind of re chargable (flywheel technology?) batteries, to power the magnets.Self defense of the beast would be provided by Goalkeeper or Phalanx CIWS, AMRAAM missiles (as used on the HMMWV) or even small VLS systems would give it good protection against aircraft and helicopters.There would be a big problem though. How would you deploy a monster like that to a warzone? Sure, by ship, but you'll need a very big LCAC or LCU to bring it ashore. Hmm... Might be an idea to take the LST's out of the mothballs. At least the Russians have the capability with their Ivan Rogov or Ivan Gren large landing ships.Well, closing off, here are some more interesting images of the original Ratter, as well as some other futuristic tanks, and possible candidates for the rail-gun super tank.Ratter...Concept image I found on the net (looks pretty defendable, but probably still easy prey for aircraft):Amazingly interesting (German language) website following the build of a 1/87 P. 1000 Ratter can be found here @ www.Panzerbaer.de Some large tank designs by Kemp Remillard . Looks like a beefed up Abrams with some Merkava influences. Not as big as the Ratter, but likely to be more "Maus" sized.Turret deployed and stowed...Well, so far my contribution to the topic. Hopefully it was worth it, and a new discussion starts from it. I like to design futuristic vehicles myself, and will try to work out some sketches (yes, with pencil and paper!) of the Rail-gun super tank.
