I am very current with the BF1942 modding community, and for now they can't make guided missiles without the SDK (software developement kit), Desert Combat is still in beta stages, they actually already had a B1-B in Desert Combat, it's just not in any maps becuase it drops like a million bombs without limit. In the next relese they will be adding a AC-130, a Nighthawk, a Hind Gunship, SU-25 (Iraqi A-10 equivalent), Howitzers, mortars, and a buttload of other stuff. Some other great mods worth checkingout are the Eve of destruction mod (

http://fhmod.bfcentral.com/), Eternal Silence (
http://esmod.bfcentral.com/, and the BlackHawk Down mod (
