(Taipei News) Mainland China continues to send military planes, warships to surround the sea outside Taiwan's island, and the airspace normal activities. From April 16th to Sunday (23), the Taiwan military discovered the PLA carrier -based anti -submarine helicopter.Outside the sea in the eastern part of Taiwan.

Taiwan scholars analyze that the mainland anti -submarine helicopter has accelerated the investigation of the sea and operated this "underwater refusal area". It may also be used as a preliminary assessment of transportation and attack helicopter activities.

Freedom Times Sunday quoted the statistics of the Ministry of National Defense of Taiwan on Sunday that within eight days from April 16th to 23rd, there were five days of discovered the PLA "straight-9" carrier-based helicopter and in the east in the Taiwan Air Defense Recognition ZoneOutside sea activities.Among them, the mainland helicopter on April 16th, 17th, and 19th in the east of Lanyu and the southeast boundary of the Taiwan Air Defense identification zone, and the scope of activities on the 22nd and 23rd move north to the east of Hualien.Mainland warships work in nearby waters.

Su Ziyun, director of the National Defense Strategy and Resources Research Institute of Taiwan National Defense Security Research Institute, said that the "straight-9" carrier-based anti-submarine helicopter may be the 054A frigate from the mainland navy's anti-submarine frigates.

From the perspective of the underwater terrain around Taiwan, the southwest of Taiwan is part of the South China Sea Basin, and east is the Hengchun Sea Spirit of the Bus Strait.The terrain has become a hot area that the PLA anti -submarine aircraft and anti -submarine helicopters are urgent.For the People's Liberation Army, collecting this information can be used for naval submarines and can also be used to predict the deployment of the Taiwan Army's submarine.

As for why the PLA anti -submarine helicopter has frequently moved in the eastern part of Taiwan in the near future?Su Ziyun believes that this may be related to factors such as the mainland naval training stream (pipeline) and walrus. For the People's Liberation Army, the marinats in the middle and late April are suitable for naval training, and it also helps to accelerate the inspection and operation of the sea outside the eastern part of Taiwan.Work, and the eastern and southwestern waters, they may become the potential "underwater refusal zone" of the CCP.

In addition, the anti -submarine helicopter activity of the frigates can also be used as a reference basis for carrier -based helicopters such as 075, which may become the preliminary assessment of the Communist Army transportation and attack helicopter activities.
