Along with the high costs involved, it was becoming clear that, due to British military satellites already being delivered by American launchers and the domestic science community being perceived as lacking the funding to conduct multiple major research satellite programmes at once, that domestic demand for such a launcher was not guaranteed. Accordingly, it was decided that it would be preferable for other nations to be involved in the programme in order to share the burden of the costs and to be predisposed to making use of the launcher. Diplomatic approaches were made to various nations, however it became obvious that the members of the Commonwealth of Nations alone were not prepared to provide the necessary backing for such a programme.
