Not all of the fleets will be upgraded but a "decent number" of each. One source says between 5-10 of each type will receive the worm drives. Others may be upgraded later on though the DDS does not envisage equipping the entire fleet in such way until the early 2120s. The equipped ships will form new sub-classes, the Provider 71B and Extender 73B respectively.
- The DDS has approved funding for a EW/ECM module for the Corkscrew 51A. The module will assist with penetrative raids and self-defence.
