The Terran Sea ILU and Unificiation Project is due to begin in January 2113 with the three Type 43 variants unified into the Type 43G. Updates will include Z7, EA-X and IWC 3.0 as well as worm drive. While the Isometric 41A is already calibrated for worm drive the Terran Sea (which has a slightly different fuselage) has not been until now.
M162 North Sea has been fitted with a W1A worm drive ahead of the ILU to help fine tuning the calibration. The Arafura Sea 43C Medium Combat Ship has also been fitted with some other ILU equipment (mostly sensor and system updates) to help their final development. North Sea will become the first ship which has the ILU proper in January and hence the lead ship of the new type which will be known as the North Sea 43G.
