GBU-28 vs. GBU-72

[DWReese]

As listed in db512:

GBU-28 4700-lb 2268 kg
GBU-72 5000-lb 946 kg

I'm not sure if this is an issue or not, but the smaller/lighter weight of the GBU-28 is listed as being 2268 kg (which is about 5000 pounds); the GBU-72 which is larger/heavier is listed at 946 kg (2086 pounds). I believe that the GBU-72's weight is incorrect.

Additionally, when flying with the same F-15E, with the same missiles (other than a swap of these two), the lighter GBU-28 is expending about 4 more kg of fuel per minute than the heavier GBU-72
