I don't know if we're getting the BRU-55 displayed in that photo. We're definitely getting the BRU-33. That doesn't mean it's not still possible, but that article clearly shows the BRU-55 being used with 2 LAU-117's to double mount mavericks.
Being able to carry 8 mavs would be so sick! But, I have no idea if the LAU-117 can be mounted on the BRU-33. Fankly, I don't have time to go through hundreds of forum posts to find out if we're getting the BRU-55. At the time i was researching, i just wanted to know if we could double mount GBU-12's on BRU-33's, which is a yes, by the way.
If we're not getting the BRU-55, then I highly doubt we'll be able to mount double lau-117's and thus double stack mavericks. The BRU-33 does not have the data bus to support anything but the basic programming of munitions. This would also severely limit the JDAM capacity of the F-18, which requires the BRU-55.
