"We must respond immediately after receiving a resistance order from the command center. As the targets in the sky are numerous, fast and highly covert, we must detect them early, fight back when they are far enough from us, and accurately intercept those that come from all the whole airspace and multiple directions, to ensure the safety of the ship."

"We must stay alert all the time. Once an unidentified target is spotted, we must immediately assess it, position it, and get prepared for engagement. Sea conditions may vary in different seasons, so we need to make adjustment in accordance with the sea conditions to track the targets in a sustained way."

"The fuel and water supplies on our ship are constantly consumed during navigation. Without proper adjustments, the ship may lose balance or even capsize in rough seas. Thus, we must adjust the ballast daily based on the ship's position, which is a way to maintain the ship's 'life.' In addition, our damage control personnel are on duty 24 hours a day, ready to respond to any emergencies with their protective gear."

The Chinese Navy's guided-missile frigate Huaibei recently conducted an emergency response exercise, aiming to improve the crew's combat response speed and operational capabilities.

The exercise was carried out in waters where the warship was carrying out its combat readiness patrol mission.

"We must respond immediately after receiving a resistance order from the command center. As the targets in the sky are numerous, fast and highly covert, we must detect them early, fight back when they are far enough from us, and accurately intercept those that come from all the whole airspace and multiple directions, to ensure the safety of the ship," said Nan Wenchao, a mariner.

For a naval frigate on a mission, it may face challenges from the unpredictable underwater environment, as the varying water temperature and wave height  would directly affect the sonar's detection depth and accuracy.

"We must stay alert all the time. Once an unidentified target is spotted, we must immediately assess it, position it, and get prepared for engagement. Sea conditions may vary in different seasons, so we need to make adjustment in accordance with the sea conditions to track the targets in a sustained way," said Chu Junmei, a mariner.

The ship has continuously optimized its combat readiness patrol tasks, operational training and daily management, hoping to complete all war preparedness tasks with high standards.

"The fuel and water supplies on our ship are constantly consumed during navigation. Without proper adjustments, the ship may lose balance or even capsize in rough seas. Thus, we must adjust the ballast daily based on the ship's position, which is a way to maintain the ship's 'life.' In addition, our damage control personnel are on duty 24 hours a day, ready to respond to any emergencies with their protective gear," said Pei Hongyi, a mariner.
