UK Navy trains submarine crews to down drones with fire hoses

Crews of Vanguard-class nuclear submarines at HMNB Clyde in Scotland are training to repel hostile drones using high-pressure fire hoses with pistol-grip nozzles. The hoses serve as a last line of defence when drones breach existing security; each submarine costs about £4 billion.

• Handheld nozzles direct pressurised water at small and medium FPV drones
• Each Vanguard submarine costs roughly £4 billion and carries Trident II D5 missiles
• The MoD announced £470 million over four years for base security
• The hoses cannot detect or automatically track incoming drones
