Defence Secretary John Healey revealed the covert operation was deterred by Royal Navy warships and RAF aircraft, with the subs retreating after surveillance. This incident highlights risks to vital infrastructure carrying internet data and energy supplies amid heightened Russian maritime activity since the Ukraine invasion.
