To try and reassure worried and angry DDS officers about the loss of the "Mars/Battle" class future frigate the DDS has confirmed an order for 3 Sea Of Tranquillity class frigates, the D evolution of the Terran Sea platform. The ships will include technology from the cancelled frigates including integrated iSAS attack software.
It will also be the first ship to deploy the next generation Z5i cannon which will replace the Z5 and Z5g in all future updates. The Z5i integrates both space and ground attack modes. The ships will also be TPM-2 ready from the off. The D will also have the latest evolution of the Meson engine. The engine may yet change as the Meson is being developed for the Isometric ILU programme starting next year and the DDS are keen to use the same varient for the D.
The first ship is expected later this year and the other 2 will be completed and in service by the beginning of 2109.
