Thanks, I have been trying to find SDB theoretical weapons loadouts for various platforms like the B-2, B-52 and B-1. I remember reading somewhere (cannot find it now) that the B-52 in a low threat counter air environment can carry close to 200 SDB's? With GPS means 200 aimpoints per sortie, incredible.

Indeed, quite impressive.

Any details on what type of explosive and how much are in the SBD?

I hope that's just a (poor) artist's impression of what an SDB II would look like. I can't think of more complicated and impractical layouts than a forward-swept wing three-lifting surface. Are they trying to achieve post-stall maneuverability ???
The current configuration works just fine.

Wikipedia says 38 lb (17 kg) of AFX-757.

The actual warload for the B-52 seems to be only 32 SDBs (one BRU-61/A rack with four SDBs on each station of the Common Strategic Rotary Launcher).

http://www.spacedaily.com/reports/Boeing_Developing_New_Smart_Bomb_Bay_Capability_For_B_52_999.html

The B-1 could carry 96 SDBs, because it has three Conventional Rotary Launchers that could each carry eight BRU-61 racks. (This hasn't been done yet, but it is in the Air Force's "wish list" for future projects.)

The B-2 has been widely cited as potentially carrying 216 SDBs, but Global Security has a nice dissection of why that isn't likely (short form; the weight of the SDBs and their racks would be about twice the nominal capacity of the B-2's bomb bay.)

well, in fact SDB II looks plain more ordinary...

Hopefully they come up with a different nose if they want to drop them supersonically. ???

I think the weight figure stated by Wikipedia for the bomb's explosive content is rather inaccurate. I can't find any common consensus but several sources I put above Wikipedia give different weights.

What makes you think they can't drop them at supersonic speed with the semi-sphere nose? Plenty of very fast things with such an aerodynamic front end.

Just seems like it would lose velocity quicker.

Article has neat picture of SDB II's internal carriage on an F-35.

Knowing why it's out of action why would you then attempt to start it in another thread?

We can let this pass as a post about the SDB, not about the F-35, I think ... ;)
