Skylon spaceplane economics stack up

It appears a feasible proposition, economically. That is the conclusion of a study that considered a European launch service based on a Skylon re-usable spaceplane.
The report, commissioned by the European Space Agency (Esa), was led by Reaction Engines Limited (REL) of Oxfordshire with help from a range of other contractors such as London Economics, QinetiQ and Thales Alenia Space (TAS).

In all the areas the study considered, it found positive outcomes. The report was intended to provide Esa with the information it needs to help evaluate what would be a completely different way for Europe to go about its launcher business.

How much would Skylon launch prices be? That's a "how long is a piece of string?" question. Re-usability and fast turnaround for the operator obviously have a significant downward pressure on prices, but there is also an issue of initial development cost and how that is recovered.
As the S-ELSO document states: "Assuming successful development of the Skylon vehicle, it was found that the S-ELSO business could be economic in exploitation and would be very competitive against a price target of 70m euros. It would also be competitive against the 41.5m-euro price target if there is some level of public support for the Skylon vehicle development programme, which would reduce the vehicle acquisition cost to S-ELSO." (The 41.5m-euro target would be the equivalent of an American Falcon 9 launch according to current SpaceX prices.)
What this means is that Skylon manufacturing and operations could be fully commercial, but some sort of lubrication in the form of a public-private partnership is probably going to be needed.
