Design
According to publicly released information, the Daguan-class ships are approximately 196 meters long, with a beam of 28 meters.[5] Capable of accommodating roughly 2,500 sailors, aircrew, technicians, and other carrier personnel, each ship has an endurance of up to 30 days. The ships are capable of a max speed of 18 knots.[5] They have a range of 8,000 nautical miles.[2] Each ship has a medium helicopter deck on its stern, which can accommodate one Changhe Z-8 heavy transport helicopter.[2]
The ships are armed with two sets of Type 81 rocket launchers, which can fire anti-submarine missiles. They are armed with an additional two sets of 57 mm twin-barreled guns and two sets of 30 mm twin-barreled autocannons.[6]
The ships are outfitted with additional accommodations for the crew, including internet cafes, coffee shops, a supermarket, a running track, a basketball court on the deck, a gym and a Sanda ring. The ships are sometimes called the "nannies" of aircraft carriers.[7] To fulfill its training role, Xu Xiake is also equipped with simulators of various equipment onboard the Liaoning.[8]
Operational history
The Daguan-class ships provide support for China's growing fleet of aircraft carriers and are also used as training ships. They also provide living accommodations for the personnel of aircraft carriers when the carriers undergo maintenance, upgrades or overhauls.[9] The first ship of the class, Xu Xiake accompanied Liaoning on sea trials. Xu Xiake provided at-sea training and R&R facilities for crew-members of the Liaoning.[10]
On August 27, 2014, Xu Xiake sailed in a group with the corvette Datong, frigate Yancheng, and frigate Linyi to Liugong Island at the mouth of Weihai bay. The ships held a memorial ceremony to commemorate the 120th anniversary of the First Sino-Japanese War.[11]
In 2018, the second ship of the class Li Daoyuan supported China's second aircraft carrier Shandong when it began its sea trials.[2] In March 2023, a Daguan-class ship was berthed with China's first indigenously designed carrier Fujian in Jiangnan Shipyard.[12] The simulators onboard the Daguan-class were likely upgraded for the more advanced CATOBAR system of Fujian.[13]
