British Sailors Train with Fire Hoses to Protect Nuclear Subs from Drones

British sailors are being trained to protect nuclear submarines from drone attacks using fire hoses. The Vanguard-class submarines, costing around £4 billion each, lack traditional air defense systems. High-pressure water jets are the only 'air defense weapon' on these submarines, used to counter small and medium-range drones. Long-range drones are defended against by fighter aircraft. The training comes as a response to changing threats, with submarines being particularly vulnerable when surfaced or docked.
