What I meant was - why would any rational person want to see "a huge spanner" thrown into the works of the QE programme, which was the implication of your post.
Particularly now when the build (of both ships) is progressing so well.
Portsmouth is perfectly capable of building T26 and larger ships. One might argue that the bigger cost savings would come from concentrating the build and in-service support of shipping in the one place (reducing overheads and giving a bigger critical mass of staff). However, that would entail closure of both Govan and Scotstoun and the end of shipbuilding on the Clyde. That level of intestinal fortitude appears to be lacking within HMG and BAES.
