ЦитироватьJuly 26 • Ariane 5 • Superbird 8 & GSAT 18
Launch window: TBD
 Launch site: ELA-3, Kourou, French Guiana
Arianespace will use an Ariane 5 ECA rocket, designated VA231, to launch the Superbird 8 and GSAT 18 communications satellites. Superbird 8 will provide communications services over Japan for SKY Perfect JSAT Corp. GSAT 18 is a multipurpose communications satellite for the Indian Space Research Organization. Superbird 8 replaced Japan's DSN 1 military communications satellite on this mission after it sustained potential damage during transport to the launch site. Delayed from July 12. [June 9]

ЦитироватьJapan's DSN-1 military communications satellite damaged during transport to launch base
by Peter B. de Selding — June 20, 2016
  The launch of India's GSAT-18 telecommunications satellite, shown here being unpacked on arrival at Europe's Guiana Space Center spaceport, will be delayed from July to at least September because its intended co-passenger, Japan's DSN-1 X-band military communications satellite, was damaged en route from Japan. Whether DSN-1 can be repaired at the launch base or will be returned to Japan was unknown. Credit: Guiana Space Center  
 
PARIS—Japan's DSN-1 X-band military communications satellite was damaged during transport from Japan to Europe's Guiana Space Center spaceport in South America and will miss its planned summer launch aboard a European heavy-lift Ariane 5 rocket, also delaying its intended co-passenger, India's GSAT-18 telecommunications satellite, industry officials said.
It remained unclear whether the damage is severe enough to require the satellite to be returned to Japan or can be treated at the spaceport facilities. Also unknown is whether the damage occurred during loading or unloading of the satellite, or during its air transport from Japan.
Launch-service provider Arianespace's chief executive, Stephane Israel, said after the company's June 18 Ariane 5 launch that the company's next mission would not occur until Aug. 24 and would carry two Intelsat-owned satellites, IS-33e and IS-36. He made no mention of the planned GSAT-18/DSN-1 launch.
Industry officials said the C- and Ku-band GSAT-18 likely would be paired with Australia's Sky Muster 2 Ka-band consumer broadband satellite for a launch as early as September, assuming no delays for the Intelsat campaign.
The Japanese Defense Ministry in 2013 agreed to finance the two-satellite DSN project as what was then Japan's first Private Finance Initiative. A joint venture, called DSN Corp., was created to manage the project from end to end, including ordering and launching the satellites and operating them for 15 years in orbit.
Sky Perfect JSat, Japan's principal satellite fleet operator, is the project coordinator and owns 65 percent of the joint venture. NEC Corp., with a 17.5 percent share, is prime contractor for the two satellites. NTT Communications, also with a 17.5 percent share in the project, is responsible for ground network management and maintenance.
Sky Perfect JSat did not immediately respond to requests for comment on DSN-1's status.
The second satellite, DSN-2, had been scheduled for launch in 2017 by Mitsubishi Heavy Industries aboard a Japanese H-2A rocket.

Tarpaulin mishap delays Japan's first military satellite by two years -sources
The launch of Japan's first dedicated military communications satellite will be delayed by two years after a mishap with a blue tarpaulin damaged sensitive antennas during transportation to Europe's Spaceport in French Guiana, two government sources told Reuters.
The mishap has set back plans by Japan's military to unify its fractured and overburdened communications network, and could hinder efforts to reinforce defenses in the East China Sea as Chinese military activity in the region escalates.
"When we need to shift units to the southwest and troops are moving down fr om the north, we need a stable communications link and this delay could affect that," a senior Defense Ministry official said on condition he wasn't identified because he isn't authorized to talk to the media.
The satellite was damaged in a plane's cargo hold on May 25 after a tarpaulin blocked valves used to equalize its container's internal air pressure as it descended into thicker atmosphere when landing in French Guiana, according to an internal Japanese government document viewed by Reuters.
The document did not detail who was responsible for the mishap, or whether they suffered any consequences.
The damage will take more than a year to fix, and could force Japan to pay tens of millions of dollars for stop-gap access to commercial communications satellites it currently uses, the sources said.
"We are not yet at the point wh ere we can decide on a new launch window. We want to do it as soon as we can," a spokesman for Japan's defense ministry said.
The satellite is first of three planned X-band satellites that will deliver a unified communications network designed to quadruple the broadband capacity of Japan's Self Defence Forces.

отсюда вроде как следует, что это один и тот же спутник (Superbird 8 = DSN 1)
ЦитироватьСпутник, названный DSN-1 для своей военной полезной нагрузки Х-диапазона и Superbird-8 для своей коммерческой телекоммуникационной миссии, был поврежден в пути к Европе Гвианского космического центра в Южной Америке в июне и потребует год или больше ремонта и переаттестации.

2018 March 16 - DSN-1 (Superbird-8 ), Hylas 4 - Ariane 5 ECA (VA242) - Kourou ELA-3 
ЦитироватьStéphane Israël‏ @arianespaceceo 26 янв. 
Flight VA241's two satellite payloads – SES-14 and Al Yah 3 – are in orbit and operating nominally, despite a trajectory deviation experienced during the launch. Upcoming launch campaigns currently underway at the Guiana Space Centre (CSG) are proceeding as scheduled.

Update on HYLAS 4
Avanti Communications Group plc ("Avanti") has been advised by Arianespace of a delay to the launch of its HYLAS 4 satellite ("HYLAS 4"), which will not have a material effect on the HYLAS 4 in-service date. Avanti anticipates a revised launch date in early April and expects to be able to confirm a fixed launch date shortly.
