GBU-31(V)1/B = MK 84 bomb, KMU-556/B guidance kit, USAF version

GBU-31(V)2/B = MK 84 bomb, KMU-556/B guidance kit, USN version

GBU-31(V)3/B = BLU-109/B bomb, KMU-557/B guidance kit, USAF version

Lockheed Martin GBU-34/B: 2000 lb JDAM (either BLU-116/B or BLU-109/B?)
I have no idea, if the GBU-34/B was really built and/or if the BLUs are correct .

Boeing GBU-35(V)/B: 1000 lb JDAM



GBU-35(V)1/B = BLU-110/B bomb, KMU-559/B guidance kit, USN


Boeing GBU-38/B: 500 lb JDAM; MK 82 bomb, KMU(?)-???/B guidance kit
I guess that there are also subvariants for USAF/USN and/or versions using the BLU-111/B warhead, but I've not seen any conclusive evidence for that.

GBU-36/B 2000 lb GAM (MK 84 bomb), GBU-37/B 4500 lb GAM (BLU-113/B bomb): As I understand it, the GAM uses the same guidance principle as JDAM (GPS-aided INS), but older technology. If I'm wrong, please correct.


Ok, that's all. I don't know if the data is really good, but look how many cool BBCode formatting tags I used in this posting !
