The DDS has taken over the UNP Space Survey Mission (USSM) which carries out surveying and mapping in UNP space, in particular along space lanes. USSM has become part of the DDS with the DDS receiving 47 million zarks a year to carry out the mission as well as a 200 million zark one-off payment to build a fleet of new ships to replace the ageing survey ships of USSM.
The ships will be built from later this year and are will use the Friendship platform. At least 5 Navigator 161A ships will be built with all needed to be in service by the end of 2117 when the existing ships become life expired.
