Repeated construction lowers cost because yards retain skills and successive ships share major design features. Italian procurement and the long Arleigh Burke production run illustrate how common hulls can absorb upgrades without abandoning the accumulated manufacturing base. A run of only five Type 31 frigates cannot realize the full benefit. Larger Type 31 and Type 26 orders would spread fixed expense, sustain the yards, and expand the escort force more economically.

How common hulls make escorts affordable
Italian production, Type 31 plans, and repeated Arleigh Burke construction show the financial value of common designs and sustained orders.
