Best-fit procurement and modern warships

The procurement problems raised by the Matilda recur in decisions about modern aircraft and warships. The F-35 was bought with decades of development in view, although delays and equipment added during procurement could consume some of the intended margin. Type 45, the future Type 83, the Type 26 anti-submarine frigate, and the general-purpose Type 31 provide a naval test of which platforms need room to grow. Stretch potential can mean an easy weapon upgrade, reserved physical space, or equipment that is fitted for but not with. The comparison ends with best-fit logic: the right choice depends on the criteria, threat, budget, and expected upgrade path.
