F122 Permian has begun its Isometric ILU, the last ship to begin the major upgrade programme. F124 Ordovician has completed the upgrade though F121 Phanerzoic is still on the jig as it also had to receive major repairs. Both ships will be completed before the end of the year.
Work will then begin on Isometric ILU Normalisation 2110, a much more modest programme to bring all of the Isometric 41A fleet to the same level of equipment and software, later ILUs had a slightly updated specification but the normalisation will bring the whole fleet up to the same standard. This work will be carried out during scheduled maintenance and will be completed by early next year. The Isometric fleet is also to receive a shield and CIWS upgrade over the next few days to protect against ABBO suicide attacks.
