Active homers also need the return to bounce straight back toward them
too. The very thing stealth is designed to defeat.


Quite so,stealth reduces backscatterers very significantly but cannot totally
eliminate it.
If you can guide an active homer close enough to your target using multistatic
tracking data,it will start receiving its own bacscatter .Figthers don't have
multistatic radars. Long range missiles cost big

$$$. If the need came up (meaning if hell froze over and we actually
saw any of these systems in service) we could just slap a small
turbojet on the SDB and be back in business.

Thats correct but air force tries to develop an UCAV based system.
