US AEGIS ships
US AEGIS ships now : 84 : 22 Ticonderoga , 62 Burke : 21 Fl I, 7 Fl II and 34 Fl IIa/Austin, and in few years 3 Zumwalt.
Burke Fl IIa Austin is different version of first Burke get a hangar for 2 helos, 96 cell's ( 6 unoccupied by cranes as in Burke ) but don't have Harpoon.
But SM-2MR are anti-ship capable with a less big warhead as Harpoon, no sea skimming but supersonic.
Only Burke Fl I/II carry SM-3 right now, almost all 26/28.
After new Burke Fl III which replace Ticonderoga, have a identical armament as Fl IIa but get a new radar : Air and Missile Defense Radar (AMDR) less big/powerful it was planned originaly because Burke hull can't receive a larger superstructure to use the radar initialy planned especialy better for detect ballistic missiles seems or he would have had a new hull ( much more expensive ) or eventually use Zumwalt hull but same problem USN get a ship expensive for built 2/years.
When LRASM will in service and SM-6 ABM, Mk 41 will be a completely versatile VLS : anti-surface, air, ASW and ABM normaly in some years.
Zumwalt for money matters get now 2 x 30 mm guns instead 2 x 57 !
actually 155 mm AGS gun is only usable against ground targets.
But with PVLS and do 14000 t definitely very difficult to sunk.
Ticonderoga attached to Cruiser Destroyer Group but it disappears since some years for be directly attached to CSG, in general 2 by unit.
Burke attached to Destroyer Sqn, between 2/9 by unit in general 5/6.
With a CSG actually for Budget reason 1 CG and 3 DDG also used with ARG but ARG receives more FF and less CG.
