Tarpaulin mishap causes two-year delay to Japan's military satellite

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.

The accident has set back plans by Japan's military to unify its fractured and overburdened communications network and could hinder efforts to reinforce defences in the East China Sea, while Chinese military activity in the region escalates.

"When we need to shift units to the southwest and troops are moving down from the north, we need a stable communications link and this delay could affect that," said a senior Defence Ministry official, who declined to be identified.

The satellite was damaged in a plane's cargo hold on May 25 after a tarpaulin blocked valves used to equalise its container's internal air pressure as it descended into thicker atmosphere when landing in French Guiana, according to internal Japanese government documents.

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 the commercial communications satellites it currently uses.

"We are not yet at the point where we can decide on a new launch window. We want to do it as soon as we can," a spokesman for Japan's defence ministry said.

The satellite is the 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.

The military needs the X-band system as it reinforces defences along its far-flung southwest island chain that stretches along the southern edge of the East China Sea, almost to Taiwan.

A lack of a common communications platform between Japan's armed forces hampered rescue operations in the wake of the 2011 earthquake and tsunami that devastated Japan's northeastern seaboard.

The accident is the second major satellite related incident that Japan has faced this year with the country abandoning its Hitomi satellite in April, which was designed to study supermassive black holes and other space phenomena, because its solar array paddles were thought to have broken off. 

Tokyo and Beijing are currently locked in a territorial dispute in the East China Sea over a group of uninhabited islands known as the Senkaku in Japan and Diaoyu in China. The two countries are also at odds over the exploitation of gas fields that straddle exclusive economic zones claimed by both.

Japan, Washington's main ally in Asia, is now worried that a recent uptick in Chinese military activity in the East China Sea is a sign Beijing wants to extend its military influence from the neighbouring South China Sea as it challenges American maritime dominance.

Japan says it has scrambled air force jets to intercept Chinese aircraft in the East China Sea more often this year and also noted an increase in Chinese navy patrols.

China recently announced its intention to launch a series of offshore nuclear power platforms to promote development in the South China Sea, despite the recent ruling from an international court that Beijing had no historic claim to most of the waters.
