That's not what I meant. The person I was replying to was very specific about the inboard wing hardpoints not being wired for data at all and only suitable for "dumb" bombs. I was merely pointing out that laser bombs aren't dumb free-fall bombs, and furthermore, there has to be some data exchanged prior to release, such as the armed state of the laser bombs and maybe whether they have achieved a lock on the beam, and so on. A very rudimentary data exchange, yes, but data exchange nonetheless.
Umm... You are right for the older legacy laser guided weapons that didnt require an active exchange of data from the aircraft, however, when it comes to advanced LGBs, there definitely is a data exchange! These types are called the dual mode LGBs, mainly american origin, they get GPS/INS data from aircraft prior to release and are made to ride the laser beam in terminal phase of flight. This actually caters for bad weather impediment.
Not sure if the LGBs of chinese origin are using this, but i have an idea that they are!
