Here are some of the weapons China's People's Liberation Army put on rare public display in a show of its growing prowess and ability to project power far from the country's shores. China unveiled nuclear-capable missiles that can be launched from sea, land and air together, the first time it has shown off its "triad" of nuclear-ready capabilities. Those included the air-based, long-range missile Jinglei-1, the submarine-launched intercontinental missile Julang-3 and land-based intercontinental missiles Dongfeng-61 (DF-61) and Dongfeng-31 - weapons that are China's strategic "ace" power to safeguard the country's sovereignty and dignity, Xinhua reported.
