The second satellite was expected to launch in January 2017, starting operations in March 2017. The program and the operations of the second satellite were expected by March 2031.

JSAT role is the procurement and general management of the satellites.The first satellite,DSN-1,is actually an additional payload on one of JSAT's own satellites,Superbird-8.The second satellite,DSN-2is a dedicated spacecraft.

A dislodged tarpaulin had blocked the bleed valve on the satellite container and the spacecraft had suffer from over pressurization damage.
