That scaled drawing is great FB.... I'm thinking it MAY need some slight fairing bulges added to clear the wingtips... which are off center-line a bit...
Nice to get the fairing comparison on one page... for future reference... SO... It will fit... it can lift it easily... Let SpaceX bid to launch it... On edit... This is an AF/DOD/NRO project after all and not just ULA/Boeing picking launchers...
The Atlas V 5-meter fairing is actually 5.4 meters in diameter, compared to Falcon 9's 5.2-meter fairing.This is why they chose Atlas V because of the roomier fairing.
It may need vertical integration. Yes it can land horizontally, but that's after mission completion.
Didn't they choose the wingspan so that it would fit inside the payload bay of the shuttle?
OR...It can do horizontal... either as is... or with mods (likely heavier) to the payload adapter and/or X-37B itself...
