NASA did not dictate changes after awarding the contract.

AIUI in SpaceX's bid NASA was given the choice of continuing to use Dragon 1, upgrading to Dragon 2, or using a mix. They choose Dragon 2 then promptly requested changes to increase the electrical power and up the internal volume by 30%.Sounds like NASA did the choosing, and paid the price. SpaceX just filled the order.
Further, they said their proposed prices tookinto account the uncertainty at the time of providing fixed per-mission pricing without knowing whetherNASA wanted them to fly the Dragon 1 or Dragon 2, which would require keeping open two productionlines.
NASA did change CRS 2 from CRSS 1, and did deliberately force volume and mass increases. There is explanation in the document.

My mistake. The source (page 10): https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20170008893.pdfThe paper you linked is a bunch of estimates. There is no such thing as a recurring price for crewed Dragon (or CST-100) excluding launch. Those contracts are for launch and operation of the spacecraft. That wording was in there because the chart also included other NASA vechicles where the spacecraft and launcher are procured separately. Adding the cost of the launch to those numbers for Dragon and CST-100 would make them completely absurd. NASA has issued task orders for flights under the CCtCap program. The task orders for the Boeing flights are $350M for each flight. The task orders for SpaceX don't show a consistent price, starting at $200M for the first one and averaging about $220M for flights 3-6 (for both Boeing and SpaceX the first two flights were done separately, and flights 3-6 as a group.)The paper is from a NASA analyst. Do you have a source for your numbers?The NASA analyst may not have had access to much of the Commercial Crew information, and it says in the paper he is estimating those prices.NNK14MA75C is the overall Boeing CCtCap contract and NNK15MA50T is the task order under it for the first Boeing PCM. NNK14MA74C is the overall SpaceX CCtCap contract and NNK16MA03T is the task order under it for the first SpaceX PCM. They have dollar amounts. You can look them up in online government contract databases.

This is perfectly normal in government contracting in the aerospace industry.
Anyway, I googled and cannot find numbers regarding NNK16MA03T, do you have a link?

Do these redesigns mean that Dragon 2-Crew and Dragon 2-Cargo are substantially different vehicles?

Do we know what was the driver behind putting thrusters in the trunk? Seems a big change given that the existing dragon and trunk work fine.Quote from: whitelancer64 on 05/01/2018 04:32 pmQuote from: Prettz on 05/01/2018 03:21 pmQuote from: woods170 on 05/01/2018 09:29 amthe Dragon 2 service module (not the trunk)What is this?Some of the Dragon v2 consumables are now in the trunk, making it a service module as well as an unpressurized cargo stowage area.
