Vietnam has rumored to strengthen its defense capabilities that they occupy the Nansha Island Reef, and deploy rocket launchers on these islands and reefs against the PLA.

According to the US Defense News and the Hong Kong South China Morning Post and other media reported on February 27, the "Asian Maritime Transparency Project" (AMTI) under the US think tank "Strategy and International Issues Research Center" (CSIS) According to the satellite images of the past two yearsThe upgrade of the island reefs in Vietnam is numbered.It can be seen that Hanoi will continue to work hard to improve its ability to resist invasion or blockade, and strengthen deterrence by ensuring that it can fight against Chinese facilities.

The report said that three types of cannons were built on most Vietnamese bases on the Nansha Islands.

The first one has a rectangular base, which seems to be to deploy the air defense system.It is usually arranged triangular. There are special bunkers but at some small outpost stations, such as Pilson Reef, are connected to the helicopter apron to save space.

The second type of platform, on the photos on the sand reef, the central reef, and the Nanwei Island, can be seen that the concrete base is semi -circular and most likely to be used for the coastal defense system.These bases are almost always along the coast, usually connected to the bunker.

The third type is a smaller circular base on the sand reef, the central reef and the southwest reef. It is generally tilted inward and the bunkers connected to them are distributed along the coast.

It is reported that most of Vietnam's larger outpost base has these guns for many years.AMTI can confirm that at least 2006 has existed on Namini.But after reclamation, Vietnam built more guns on the new coastline.All 10 islands controlled by Vietnam have these guns.

It is reported that Vietnam also has a more advanced remote weapon system at its outpost base.Reuters reported in 2016 that five of the Extra rocket launched from Israel to the Nansha Islands from Hanoi.Its range is 150 kilometers and the combat department is 120 kg, and the rate of round probability is 10 meters. It has been able to crack down on all Nansha bases in China.This is a considerable deterrent ability for Hanoi.

Analysis believes that if Vietnam United in the United States, take military operations at a critical moment, may temporarily allow the Chinese army to be disabled at the airport of the Yongli reef; if the U.S. military launch an air strike at the airport at this time, the airport may lose its combat effectiveness.
