The only weapon that the US did not remove from the Vietnamese ship CSB 8021

Coast Guard ship John Modgett was removed almost all weapons by the US before handing over to the Vietnamese side, only one cannon was left by the US side.

According to information posted by the US side, the ship CSB 8021 has been renovated and tested by the US side, handed over to the Vietnamese side, and set off to return home. Before handing over to the Vietnam Coast Guard, the ship CSB 8021 was completely repainted by the US side with Vietnam’s national emblem and flag; and especially, the US side removed some weapons from the ship. One of the weapons that was removed from the ship by the US, was the high-speed Phalanx artillery batteries used for close-range defense. The Phalanx short-range defensive high-speed artillery system, considered the standard weapon, appears on nearly every American warship. Born in the 80s of the last century, Phalanx high-speed cannon is designed to be able to fire automatically, its target is objects flying at close range, including aircraft, cruise missiles, … of the opponent. The strength of this weapon is that it has an automatic control mechanism, can use pre-installed radar, to follow the target and fire itself, the firing rate of the Phalanx high-speed cannon is up to 4500 rounds. /min – equivalent to about 75 tablets/second. Also one of the very powerful weapons, however, the US side did not remove the OTO Melara 76mm cannon from the CSB 8021 ship before handing it over to Vietnam. Designed by Italy in the 60s of the last century, the 76mm OTO gunboat is still commonly used on many small American and Western warships. One of the most “expensive” features of this gunboat is that it has an extremely fast rate of fire, up to a maximum of 85 rounds per minute – that is, firing twice every 3 seconds. In addition to the fast rate of fire, the OTO 76mm gunboat also has an extremely advanced cannon stabilization mechanism, which allows to accurately fire the target at a distance of over 10 km. The range of this cannon, depending on the type of ammunition, will be able to shoot up to 16 km to a maximum of 40 km with the most modern Vulcano version. For a fast rate of fire of up to 85 rounds per minute, all incoming OTO 76mm ammunition is housed in a rotating magazine with an electrically automatic reloading mechanism. Theoretically, this automatic magazine can hold up to 80 rounds – that is, with the maximum rate of fire, the 76mm Melara cannon can fire all the ammunition in the magazine in less than time. 1 minute. To ensure the ability to operate at high intensity, the OTO 76mm naval gun has a liquid-cooled mechanism, avoiding the temperature of the barrel and the firing mechanism being pushed up too high. This cooling system can use seawater or fresh water depending on different settings. Close-up of automatic ammunition of the OTO Melara 76mm cannon. Image source: USnavy.
