All three Pentekonters will also be upgraded to a higher specification with passive sensors and an improved databus among other improvements. The ship already delivered will be upgraded by a visiting DDS team later in the year and the two others built to the improved standard. It is thought part of the cost of the order has been offset by the Helinox leasing a small moon in their system to the DDS for use as a listening post. Helinox's location makes it ideal for watching the 7 Sa Sao (and Benito's half of the CSE).
