Keeping the Type 23 production line open through batches of three every four years could have renewed the class while preserving shipyard work, with older ships sold as newer ones entered service. In the proposed rotation, a sixteen-ship force could sustain four operational frigates alongside ships training, returning from deployments, and undergoing maintenance. In an emergency, drawing a couple each from ships working up and ships returning could lift the available force to eight without major disruption. Selling three Type 23s to Chile is criticised for reducing that margin. Maintaining four operational ships from twelve or thirteen hulls puts more pressure on the remaining force and leaves less slack when something goes wrong. The Type 45 example makes the same point through planned numbers and weapons fit: building all twelve, even with some held in reserve, and installing their full VLS capacity, including Mark 41, from the start would have created more options. Procurement needs to preserve room for demands that cannot be predicted when the ships are ordered.

Type 23 and Type 45 choices that removed fleet slack
Type 23 numbers and the Type 45 weapons fit show how production decisions set readiness, surge capacity, and future options.
