Superbird-8 (2014 to launch) Superbird-B3 (from launch onward) DSN-1
Superbird-B3, known as Superbird-8 before launch, and DSN-1 (Kirameki-1) for its military payload, is a geostationary communications satellite to be operated by SKY Perfect JSAT Group and designed and manufactured by Mitsubishi Electric on the DS2000 platform.
It is intended to replace Superbird-B2 on the 162° East slot, offering Ku band and Ka band communication services to the Japanese market. It will also serve as one of the two planned X band military satellites of the DSN network, in this role, it will be known as DSN-1 (Kirameki-1).
Originally intended to be launched by an Ariane 5 ECA in the second half of fiscal year 2015, a mishap during transport to the launch site on March 2016 meant that it would be delayed up to two years.
JSAT along NEC, NTT Com and Maeda Corporation formed a joint venture called DSN Corporation. On January 15, 2013, DSN Corporation announced that it had closed a contract with the Ministry of Defense to execute the "Program to Upgrade and Operate X-Band Satellite Communications Functions, etc". The contract is a private finance initiative, where private funds, management and technical capabilities are used to upgrade and operate the Japanese military X band satellite network.
