The tricky part in the construction phase was making them sturdy enough to withstand deep-sea water pressure, while being light enough for transport by airplanes, ships or trucks. The first two DSRVs were in the water by 1970 for testing. After successful rescue exercises were completed, the DSRVs were delivered to the Navy and put into service in 1971. The Navy dubbed the two rescue vehicles Mystic and Avalon. The DSRV-1 Mystic being checked off the coast of southern California. The Mystic and Avalon are nearly 50 feet long and weigh close to 50 tons each. They have a maximum depth capability of 5,000 feet and are equipped with Doppler radar and three types of sonar. Six different video cameras and one 35-mm still camera send visual information to the surface. The Avalon has an inactive status now because of its age, but the Mystic remains at the ready for deployment anywhere in the world. Russia’s support for separatists in Ukraine has put Beijing in a “tough spot”, said David Gitter, president of the Center for Advanced China Research, as it takes a hard line against suspected “separatists” in regions like Xinjiang, Tibet, Hong Kong and the self-ruled democracy of Taiwan. China has never recognised Russia’s 2014 annexation of Crimea, although Gitter said that Putin’s use of “cultural and historical affinities” with Ukraine might provide some future legitimacy as China’s Communist Party uses similar arguments to claim sovereignty over Taiwan. Another reason is that despite growing closer with Russia, China still has a close economic relationship with Ukraine. Trade between the two countries amounted to $15.4bn in 2020, according to the State Statistics Service of Ukraine. Among Ukraine’s exports to China are raw materials like ore, slag and ash used in important domestic industries like construction. Similarly, Ukrainian President Volodymyr Zelenskyy has pitched Ukraine as China’s “bridge” to Europe, which is also an important market for Chinese goods. mp3
