    No enlargement, it's the exact same hull. The modifications - basically a bow thruster, a different genset and upgraded electronics - are the exact same as those made for F-105 Cristobal Colon (and the cancelled ship F-106) laid down 3 years before Hobart.

    I wrote "enlarged" because it's roughly 700 tones heavier...

    How does AEGIS work?

    It's an enlarged & modified version.
    So, SPY-1 doesn't have enough resolution for terminal guidance? Because it's S-band?

    Can Mark 99 illuminators engage multiple targets simultaneously by mechanically slewing the antenna like PD radars on fighters?

    If the SAM has terminal guidance of its own, then Mark 99 is basically not required?

    Does it mean that Hobart can engage many aerial targets in rapid succession butnot simultaneously by using SPY-1 for mid-course guidance and Mark 99 for sequential terminal guidance?

    The SPY-1 radar provides mid-course guidance data to get the missile in the vicinity of the target

    The SAM targets using semi-active homing, requiring the MK99 antenna to illuminate the target with continuous wave RF. The missile uses this like you would use a flashlight to look for something in a dark room. The MK99 can only illuminate one target at a time. The reflected energy is necessary for precise timing to trigger the proximity warhead.

    The SPY-1 can provide mid-course guidance data to multiple missiles at a time. The target must be illuminated during the time the missile will engage it.
