The DDS are to update all Terran Sea frigates with the Terran Sea Tactical Pod (TSTP). It was originally just going to be part of the Terran Sea-C sub-varient but funding has now been found to improve all existing Terran Seas too. The TSTP replaces the Z-cannon with an integrated weapons pod that includes an improved Z-cannon, a new missile launcher, 2 CIWS and some EW equipment. The missile launcher is the new type that will equip the next generation of DDS ships including the Quasar ILU and Panther. Because of less advanced fire control systems Terran Sea TSTP will only be able to fire 4 missiles at any one time and not 8 which is the launcher's limit.
The Terran Sea's existing belly mounted launcher will be replaced with the new small launcher which is intended for smaller ships and auxiliary armament. This will (with some storage in the TSTP itself) increase Terran Sea missile storage from 64 to 80. The first TSTP will be fitted to a ship later this month.
