The Ajax programme included construction of a new factory in Britain. Hulls arriving from Spain had been produced by a workforce accustomed to the Spanish version and its requirements. Mixing those practices with British components and measurements created shape and fit problems. Transferring a production line requires common standards, tooling habits, and quality control rather than merely ordering nominally related parts.

Moving Ajax production into Britain exposed the danger of combining hulls built to one national requirement with components and measurements intended for another.
