How does AEGIS work?
Originally posted by jlvfr View PostYou are puting diferent equipments into one bag. AEGIS is not a radar, it's an integrated system of various electronics, the most known and visible being the Phased Array SPY-1 search radar; emphasis on search. While the radar can also control multiple missiles in flight, final (terminal) guidance is still the job of dedicated, separate, systems.
It's an enlarged & modified version.
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?Last edited by hboGYT; 06 Feb 20,, 20:17.

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.

With the threat of small boats and unconventional warfare these days, warships have been adding 20-35 mm cannon mounts for self-protection. But the line of fire directly ahead of the ship has always seemed to be a weak spot to me. Why have we not yet seen a "prow gun" such as depicted below?

There are pintle mounts for .50 caliber machine guns right at the bows of the Burkes, among others, I'm sure, but they're able to be removed or reinstalled as needed.“He was the most prodigious personification of all human inferiorities. He was an utterly incapable, unadapted, irresponsible, psychopathic personality, full of empty, infantile fantasies, but cursed with the keen intuition of a rat or a guttersnipe. He represented the shadow, the inferior part of everybody’s personality, in an overwhelming degree, and this was another reason why they fell for him.”

If you are emotionally invested in 'believing' something is true you have lost the ability to tell if it is true.
