The Mark 3 Dinomark PT has been in development for some time and it was hoped for the new type to enter service early next year but this has now been put back to the end of 2111 at the earliest. The delay is to allow for the development of a new tactical sub-system to take advantage fully of the TPM and some further enhancements to the power grid.
To plug the gap production will revert to the Mark 2b next year (or PT/2b). This will have improvements to damage control and recovery, an improved missile launcher and improved passive sensors.
