Chinese researchers have just carried out the first test of what they believe will be the world’s deepest-reaching underwater glider – challenging the record held by a vessel now in use by the US Navy. The Haiyi-7000 – carried on board the maiden voyage of China’s submersible mother ship, Tansuo-1 – was deployed above the Mariana Trench, in the western Pacific, an ocean trench with the greatest known ocean depth of 11,034 metres from late June to early August. It was able to glide down to a depth of 5,751 metres and its progress has greatly interested the People’s Liberation Army Navy.
