Hiroshima development

[Thexare]

I'm gonna try my hand at rewriting the descriptions. You've got some awkward phrasing in there. I'm a bit tired, so I may be able to do better tomorrow...

Built in 817 AS, Kure shipyard is the latest acquisition of the Naval Forces.
Superior equipment does not only give it the ability for construction and maintainment of all Naval Forces capital ships, it is also known as a research and development center.
Parts are temporarily used as storage for the toxic waste gathered from the Iwo Jima cloud.

"Built in 817 AS, Kure Shipyard is the latest acquisition of the Kusari Naval Forces. Thanks to its superior equipment, it can be used for research and development as well as capital ship construction and maintenance. Some sections are temporarily used as storage for the toxic waste gathered from the Iwo Jima Cloud."

The Iwo Jima cloud is an outcropping of the Crow nebula attracted by the Hiroshima's twin suns gravitational field.
Venturing inside is to avoid, because of extreme high radiation sweeping its depths, apparently produced by the remaining parts of a destroyed station.
Rumors are spread about a failed antimatter experiment by the Naval Forces.

"The Iwo Jima cloud is an outcropping of the Crow Nebula, attracted by Hiroshima's two suns. The cloud is very dangerous, due to particularly high radiation surrounding a destroyed station. Rumors of a failed antimatter experiment persist, but have not been confirmed."
