Fair point - but I see no reason why you'd commision unsupportable ovens or lifts - these are not unique things to aircraft carriers. I'd suspect custom ovens

Fair point - but I see no reason why you'd commision unsupportable ovens or lifts - these are not unique things to aircraft carriers. I'd suspect custom ovens or lifts are more likely to breakdown than some standard industrial ones whose manufacture and design has been optimised over many years. Just like new software is much more likely to have bugs that battle tested ( sic ) software.
