3 pads? They'll only have 2 F9 capable pads once the VAFB pad conversion is completed, whenever that will be.And since they plan on launching from VAFB, that would probably rule out a Kwaj F9 pad as well, since there would be no point to have it. (equatorial launches from CCAFS, and polar launches from VAFB)

I actually suspect Russia and China might still be getting a few of the Iridium NEXT launches for diversification/scheduling purposes, so they haven't lost quite yet. It looks like SpaceX is the primary launch provider, though.
So who "lost" this business then?
It's difficult to imagine the DoD will overlook the "Operationally Responsive Space" implications of a new U.S. launch system that provides polar-orbit capability, especially when the system will have a high launch rate for commercial payloads. The ability to swap out an Iridium payload for a high-priority DoD payload "on demand" must make a contract with SpaceX look awfully tempting.
To put SpaceX’s declared intentions in context, an official with one non-U.S. company planning a telecommunications satellite intended for geostationary orbit 36,000 kilometers over the equator said he recently sought price quotes from SpaceX, from the Indian Space Research Organisation and from China Great Wall Industry Corp. SpaceX, he said, was the least expensive of the three.
Jean-Jacques Dordain, director-general of the 18-nation European Space Agency (ESA), said during a June 8 press briefing in Berlin that Europe needed to learn from what SpaceX is doing. He acknowledged that part of the company’s recipe — a single manufacturing and production facility — would be difficult to replicate in Europe because each ESA member nation wants work for its own industry in return for helping financing the Ariane system.

(equatorial launches from CCAFS, and polar launches from VAFB)There was an earlier wager that someone made with Jim that SpaceX would, in ten years, have more annual launches than ULA, no matter the launch vehicle.

It hasn't demonstrated operations with a complex spacecraftc. Spacecraft themselves are not responsive.d. The DOD payloads will have mission unique requirements.e. It is no more responsive than Atlas. The time in the hangar is no different than the time Atlas spends in the VIF. Atlas rolls out to pad a day before launch.
All good questions. Anyone know the answers together with this one: What's the launch manifest for ULA over the next few years? SpaceX is about 5 per year through to 2014 with a couple of ISS Resupply in 2015. That's F9 and F9/Dragon. There's a few F1e in there as well. Think they're going to be quite busy! Wonder what else is in the pipeline since Elon mentioned new contracts to be announced following the successful maiden F9 flight or have we heard about them all?And we don't yet know what's going to happen with either COTS-D or some other variant for human transport.
Kwaj maximizes payload to orbit over VAFB and CCAFS

1. Count the number of DoD payloads that meet the performance of F9 and those that don't.2. Besides, we are talking about responsive spacelift and responsive spacecraft. Huge behemoth sats don't qualify for that market.3. Can Atlas recycle a launch count within hours of an abort?4. And what is the launch price of an Atlas vs F9?
4. By the time F9 will be viable for DOD missions, the cost difference will be in the noise.
