Signed in 2104, the SALT-17 Treaty was an agreement forged by the Federation and the Chinese Empire, prohibiting both sides from further developing and employing Kerolin stealth missile technology in warfare.

The treaty works entirely as planned for nearly four decades, until a misunderstanding by the Empire's leader - Xu Derui - over the fate of their new generation ship leads him to breach the treaty on the morning of February 17th, 2143; a conflict that lasts merely eight hours.
