La pr\u00e9cision requise \u00e9quivaut \u00e0 frapper une pi\u00e8ce d’un Euro \u00e0 un kilom\u00e8tre de distance.<\/h2>\n

Lors d’un essai au champ de tir des H\u00e9brides du minist\u00e8re de la d\u00e9fense,<\/abbr>le syst\u00e8me DragonFire d’arme \u00e0 \u00e9nergie dirig\u00e9e par laser(LDEW)<\/abbr> a r\u00e9alis\u00e9 le premier tir \u00e0 haute puissance d’une arme laser contre des cibles a\u00e9riennes au Royaume-Uni. La port\u00e9e du DragonFire est classifi\u00e9e, mais il s’agit d’une arme de classe \u00a0\u00bb ligne de mire\u00a0\u00bb qui peut s’attaquer \u00e0 n’importe quelle cible visible.<\/p>\n

DragonFire exploite une technologie britannique pour pouvoir d\u00e9livrer un laser de grande puissance sur de longues distances. La pr\u00e9cision requise \u00e9quivaut \u00e0 frapper une pi\u00e8ce d’un Euro \u00e0 un kilom\u00e8tre de distance.<\/p>\n

\"\" \"\"<\/p>\n

Les armes \u00e0 \u00e9nergie dirig\u00e9e par laser peuvent atteindre des cibles \u00e0 la vitesse de la lumi\u00e8re et utiliser un faisceau lumineux intense pour endommager la cible, entra\u00eenant une d\u00e9faillance structurelle ou des r\u00e9sultats plus percutants si l’ogive est cibl\u00e9e.<\/p>\n

Le fait de l’allumer pendant 10 secondes \u00e9quivaut \u00e0 l’utilisation d’un radiateur ordinaire pendant une heure. Il pourrait donc constituer une alternative \u00e0 long terme et \u00e0 faible co\u00fbt \u00e0 certaines t\u00e2ches que les missiles effectuent actuellement. Le co\u00fbt d’utilisation du laser est g\u00e9n\u00e9ralement inf\u00e9rieur \u00e0 10 livres sterling par tir.<\/p>\n

Le syst\u00e8me d’arme DragonFire est le r\u00e9sultat d’un investissement conjoint de 100 millions de livres sterling du minist\u00e8re de la d\u00e9fense et de l’industrie. Ensemble, les entreprises concern\u00e9es soutiennent des emplois britanniques hautement qualifi\u00e9s dans le domaine des nouvelles technologies de pointe qui permettent de franchir une \u00e9tape importante dans la capacit\u00e9 du Royaume-Uni en mati\u00e8re de syst\u00e8mes LDEW<\/abbr>.<\/p>\n
