Yes it has 2 Phalanx 1B systems port and starboard. I must say against a Mach 3 target taking evasive action, I would bet too much on them. One thing that is overlooked is that a T45 can manoeuvre itself into an optimal Chaff C and D pattern without compromising it weapons capability in any way. An AB always needs to have the availability and arcs of directors in mind.
