A Landing Craft Air Cushion (LCAC), attached to a landing ship flotilla with the South China Sea Fleet under the Chinese People’s Liberation Army (PLA) Navy, steers into the well deck of the amphibious dock landing ship in waters off the Xisha Islands during the maritime coordinative training from March 6 to 11, 2019. The widths of the hovercraft and the mother ship dock difference less than 1 meter. With its two high-power air propellers on the rear, the direction and speed are extremely difficult to control. A tiny mistake may cause deadly collision accidents. (eng.chinamil.com.cn/Photo by Liu Jian)
