It was designed by the French - Thales.
It has Phalanx I suppose so a 40yr old close defence gun which could deter drones?
Noticeably the Phalanx discharges its 4500 rounds within 1 minute. Each magazine of 3 (1500 in each) costs $135,000 once discharged, averaging $30/round of depleted uranium shells.
On three previous occasions, the gun has engaged drones @ sea (killing two sailors) and taken out an Intruder A6. It also locked onto the Missouri launching chaff at a range of 3 miles, hitting the ship with atleast 4 rounds.
Overall I believe the ship was built to take the gun to sea - because the gun seems to have a better war time record than the ship
At £650,000/day, shes' going to milk the budget dry before firing one shot in anger.
