I wonder if they should go with Babcock / OMT Arrowhead design for the T31, which is based on OMT Iver Huitfeld FFG already in service with the RDN. Most of the heavy lifting has been done and more importantly there already has been significant derisking. It can be FFBNW so that if necessary can have upgraded weapons and sensors capabilities similar to the T26. Using the same systems such as the Mk 45 5" gun, Sea Ceptor, Mk 41 VLS, and CMS as the T26, where possible, gives advantages and synergies of commonality. As long as the RN, MOD and pollies don't get bright ideas about bespoke systems unique to the T31, because, these bright ideas just drive costs up. Whilst they won't use the Danish STANFLEX system, as long as they stick to the OMT build philosophy and design, the ship will still be modular enough to allow for relatively easy and less expensive changes and upgrades over time.
