How fewer aircraft types make room for more carrier spares

Reducing a carrier air group's aircraft types also reduces the separate support systems carried with them. Different airframes need their own engines, parts, tools, lubricants, training materials, and personnel preparation. A multi-role type can cover several missions while removing one set of those demands. The example starts with storage for six spare engines across three types. Reducing the fleet to two types can release enough supporting-parts space to carry eight engines in the same overall volume. The benefit is both simpler support and a larger usable reserve of common components.
