L’US NAVY teste un railgun : Canon électromagnétique. 8000 Km/h !
La Marine US teste un canon électromagnétique qui peut lancer un projectile de 10 kg à une vitesse supérieure à Mach 7, pour une portée de 160 km environ. Plus précisément : 8000 Km/h….!!!!
Selon l’US NAVY, chaque projectile de 45 cm coûte environ 25.000 $, comparativement aux 500,000, voire 1,5 millions de dollars pour un missile conventionnel.
Il ne nécessite pas d’ogives explosives. Les frappes sont donc vraiment chirurgicales car il n’y a pas ou peu d’effets collatéraux, si ce n’est l’auto-explosion de la cible. Le projectile en lui-même n’explose pas, il ne se sert que de sa propre énergie cinétique.
