Ja tam już dawno w sklepiku PSE kupiłem. Dziwi mnie tylko, że import jest tańszy niż nasz krajowy AC6 :| Kogoś chyba ładnie tłucze.
Ostatnio w Empiku widziałem GRAW na X360 (z kolekcji Classcis) za 239zł

EDIT: Dzisiaj sobie wreszcie przeczytałem artykuł o działach szynowych ze świata AC. Nie wiem jak Wy ale ja uwielbiam po prostu czytać wszystkie smaczki o tej wspaniałej serii. Ten z kolei jest tak bliski rzeczywistości, jak tylko możliwe - ciekawe czy takie coś kiedyś powstanie?
CYTAT(Titan Guns)
'Toward Absolute Trust Ability'
The official name of the Interceptor Cannons is "the 120cm-Caliber-Anti-Surface-And-Air Gunpowder-And-Electromagnetic-Propelling Semiautomatic-Fixated-Guns." This is an extended form of a rail gun with hybridized propelling forces. First, gunpowder is used as a propellant, and then the projectile is accelerated even more with magnetic forces. The top speed of the projectile is 6km/sec by using this method. Originally, they aimed for the acceleration up to 8km/sec (= Mach 23 = 1st Cosmic Velocity). However, considering time that can be spent for the development and the reliability needed for the project, it's decided that it should not be so. To that end, the development is now being done on a currently practical level along with existing technologies.
The reason why they choose gunpowder first is that if the projectile is accelerated solely by magnetic forces, then Joule heat (heat released when an electric current passes through a confuctor) will melt the gun turret. Also, a vast quantity of electricity is consumed in a single firing sequence. So, in order to save the quantity of electricity charged in the capacitor and to facilitate consecutive firing, the dual use of gunpowder and electromagnetic forces.
How to charge electricity in the capacitor was the largest issue in this Asteroid Intercept Project. Electric power itself could be supplied by the specialized nuclear power generator, but the size of the capacitor capable of accumulating such a large quantity of electricity would be quite a problem. In addition, in the early stage of the development, it was under consideration whether or not the rail guns should be locomotive, but the idea was later abandoned because the rail guns themselves could be so made, but the capacitor couldn't. It was inevitable that the size of a capacitor that could store as much energy as this would be unrealistically huge. In the end, 20% of the base site was covered with the capacitors.
The capacitors need to be charged every time the rail guns fire, which makes cannonade difficult. The Asteroid will disintegrate into numerous fragments. Even if 100% precision firing could be achieved, it would be meaningless. The Project Team solved this problem by disposing 8 rail guns in a circle. By this arrangement, all-sky coverage was attained. This also contributed to the realization of consecutive firing to engage multiple fragments at a time and simultaneous firing to engage a single huge asteroid fragment. The blast radius and accuracy greatly improved due to this disposition of the cannons. These ideas were initiated by placing priority on saving human lives over anything else for perfect reliability.
The control systems to facilitate these features were also required of amazing quality. Beneath the base are a complex of supercomputers. This is comprised of 8192 of them, 1024 sets of 8 parallel supercomputers, each of which are linked by high speed networks. Each computer performs 9 billion floating-point arithmetic operations per second, and the system as a whole can perform 100 trillion floating-point arithmetic operations per second. Based on data and information sent from observatories across the world and satellites in orbit, the system simulates the entire Usean Continent's atmospheric conditions and calculates the asteroid fragments' points of impact. The rail guns then fire the projectiles.
Concerning the projectiles, there are several types of them. The APE round -Armor Piercing Explosive Ammunition-, which is considered most technologically complex, is to make a direct hit on an asteroid fragment, cause an internal explosion, and smash it into pieces. Shells will be fired upon small fragments to place priority on precision over destruction. The Dr. mentioned, although not in detail, the existence of a special projectile which has a very wide range of destruction. According to him, this is quite useful in sweeping out numerous small fragments at one time, but its use will be permitted only under the temporary special measures act.
We can't hold back the sense of awe before this absolute potential. But the Dr. continues, "This is here solely to open the door to the future of mankind." In fact, the development team defines a rail gun as a kind of EML - Electro Magnetic Launcher - , and avoids calling it KEW - Kinetic Energy Weapon.
