The suggestion of earlier carrier-design work rests on internal Royal Navy references to Cammell Laird as a yard with particular strike-carrier expertise. Those descriptions occur during Ark Royal's design, although the yard had not previously built a carrier. An Admiral-class hull at the yard is identified as the plausible earlier conversion candidate. The proposed work remains an inference from the documents' language.

Cammell Laird carrier expertise suggests earlier design work
References to Cammell Laird as a strike-carrier expert suggest design work before Ark Royal, with an Admiral-class hull as the proposed connection.
