USN Aircraft Carriers have Sea Sparrow and Phalanx. Yet, they just fired a ESSM from a Sea Sparrow box launcher. So, I beileve the plan is to convert them to fire ESSM at some point. As usually ESSM are fired from Mk-41 VLS. Regardless, I would support a gun/missile defense. Hopefully the trend continues????

Well if DDG-1000 is anything to go by it will.;)
