Why Type 83 should be more than an enlarged Type 26

Will Type 83 essentially be a Type 26 fitted for air defense?

No; its expected missile load and general-purpose systems, together with anticipated yard expansion, point to a much larger design.

The November 2025 expectation is that Type 83 will need many more VLS cells and broader general-purpose capabilities than Type 26. Those requirements imply a substantially larger ship. Some architectural ideas could carry over, such as a hull designed to accept an inserted midships section, although that commonality is explicitly uncertain. BAE's continuing design development provides another reason to expect changes before construction. The anticipated enlargement of the building yard is offered as a further indication of the size difference. Sharing a builder and some design methods would therefore leave considerable room for a distinct successor design.
