SpaceX is the "dinosaur" now, so it can ask a higher price. Not surprising at all.
Quote from: Hauerg on 02/06/2016 06:09 pmSince there is no mention of it being optional or at extra cost, this might indeed mean an all-SD fleet.As yg1968 noted, the source selection references "accelerated cargo return," which likely requires end of mission near KSC (either at the SLF or LZ-1). A couple of quotes from Mr. Gerstenmaier's statement:"However, I noted that for one of the two missions the accelerated cargo return is an option that would require additional cost.""Sierra Nevada and SpaceX also provide accelerated return, although this is at additional cost for one of SpaceX’s two missions."

It's just that their volume has expanded and they can offer a lower price IF you're just considering pressurized downmass. Not everything has to fit a certain narrative.

That would likely be the added cost.
Does anyone happen to have the source selection document/s for CRS1? I was trying to find them for comparison, but so far haven't been able to.

Not everything has to fit a certain narrative.OA's financials also made it seem that their program was amortized over the course of CRS1. So while they still have to modify their LV they have nowhere near the startup program costs like before, so they can greatly reduce their bid. SpaceX's financials aren't public but it's possible they are amortizing over a longer period which allowed them to make a very aggressive bid for CRS-1 but doesn't allow for reduced rates for follow-on contracts. Purely speculation though.
...SpaceX also has a launch-on-need capability. Although this is an option that comes at addotional cost....
Interesting. From page 14/22Quote...SpaceX also has a launch-on-need capability. Although this is an option that comes at addotional cost....What exactly does launch-on-need meant?
I wonder if the price issue was one of rounding problem. Both DC and Cygnus are able to do 7,500kg of pressurized with 2 missions. But SpaceX could need 3 missions. If they bid an average 180M/mission, that's 72k usd/kg. That's 30% above Cygnus.

If your assumption is correct that SpaceX bid $180M per mission, it would then mean that each DC flight would essentially cost $270M per mission ($180Mx5000kg/3310kg) which is what you would expect (according to the Source Selection Statement, SpaceX was essentially tied with SNC on prices for bringing up 7500 kg of pressurized upmass and 1000 kg of unpressurized upmass to the ISS). Orbital ATK's prices are already known and they are $200M per mission for Antares-Cygnus and $250M per mission for Atlas-Cygnus. Based on the assumptions above, the prices per kg for pressurized upmass would be $54,000 per kg for SpaceX (180M/3300kg), $54,000 per kg for DC ($270M/5000kg) and 53,000 kg for Antares-Cygnus or $56,604 for Atlas-Cygnus. Based on these same assumptions, the total contract price would be $1.1B for SpaceX (6 x $180M), $1.6B for SNC (6 x $270M) and between $1.2B and $1.5B for Orbital ATK.
