thank you. 🙂

It wouldn’t matter if SPY could guide 1000 missiles if you only have one illuminator and the missile requires 2-3 seconds of terminal guidance.

It would matter if three illuminators are working on three different targets, and even if it takes them 3 seconds to terminally guide an interceptor, then say three more seconds to move and acquire another set of three different targets and repeat that two times, all the while each interception is done by two missiles, to ensure greater kill probability. that is 21 seconds all in all, for 12 different targets and 24 interceptor missiles.

Even if they use only one interceptor missile that is 12 missiles in 21 seconds or 24 missiles in 42 seconds. A harpoon class attacking missile would take more than 42 seconds to travel 25 km from the horizon to the ship. at 900 kmh it would take the said missile 100 seconds to travel over 25 km.

There seems to be ample reasoning for being able to provide midcourse updates to more than 20 missiles at any one given time.

All that being said, how come a passive array like spy-1d has multiple emitters? They wrote each array has 8 of them. What do those emitters do? What is their purpose? Are they involved with providing midcourse updates?

Polmar and Friedman in their respective books, say SPY radars provide guidance for perhaps 20 missiles at any time. They also mention each arrach has 8 transmitters (how? SPY is PESA, shouldnt it have one transmitter?) and total of 32 CFAa (what is CFA?). Should i read that as ability that each face can guide 32 missiles? 128 for complete system in ideal circumstances? But why do they themselves settle on ‘perhaps 20’ missiles?

yeah, like that. as we see, hangar is always a bit narrower than waterline beam, even though in theory theres enough width for a broader one. why is that?
