On August 3, 2009 (June 13, 2009 lunar calendar), the third batch of Chinese naval escort formations used single-ship escort for the first time. At noon on August 3, 2009, the third batch of Chinese naval escort formations carried out the second batch of escort missions in the eastern waters of the Gulf of Aden. Unlike the first escort, this escort was carried out by the guided missile frigate "Zhoushan" alone. This is also the first time that the third batch of Chinese naval escort formations used single-ship escort to carry out tasks. At 12:00 local time (17:00 Beijing time), the eastern waters of the Gulf of Aden were calm, and the guided missile frigate "Zhoushan" set sail for the second time at sea. Three protected commercial ships, including the "Yuguhe", "Knight" and "Carmen", were on the left side of the warship. In the next two days, they will be escorted to the safe waters at the east entrance of the Mandeb Strait. It is understood that during the single-ship escort of the "Zhoushan" ship, the "Xuzhou" missile frigate will perform duty patrols and other related escort tasks in the eastern waters of the Gulf of Aden to ensure the safety of ships arriving in the area to be escorted. Comments: Single-ship patrol and single-ship escort, our army's escort capabilities have been improved
