Shipyard capacity follows money and procurement intent

Could Cammell Laird build a 100,000-ton aircraft carrier?

Yes, if the customer paid to expand the yard; the practical constraint would be cost and procurement commitment rather than an absolute inability to build it.

Cammell Laird or another commercial yard could build a very large carrier if the customer funded the necessary facilities and accepted the price. A proposed davit for amphibious or logistics ships illustrates the distinction: its required capacity was only slightly beyond an existing product, yet officials treated that gap as a reason to abandon the project. Procurement claims should therefore distinguish technical impossibility from a budget limit or a decision that the program is unwanted.
