What is underwater ghost frogman? Why are navies afraid of frogman
4hw.org: frogman is actually a stand diver's nickname. It's called a ghost like existence by all countries. They lurk in each other's military port to collect intelligence and investigate the nearby fortification. Generally speaking, it can be called an underwater spy. But why can this "frogman" cause the panic of the navies of all countries? Let's learn about it together!
According to a report published on August 3 on the website of the monthly journal of popular machinery, fear of frogmen - why are navies all afraid of 'ghostly' combat divers?, navies all over the world are very worried about the divers who wear underwater breathing devices to dive near military bases. These unauthorized divers are like ghosts.
China claims to have divers close to a ship in the country, and the US has recently launched an emergency hunt for underwater ghosts. China claims that during the docking of its ships in Djibouti, 'Japanese warships sent frogmen to approach a Chinese warship'. The Japanese military did not report the incident.
But Jian Jiamin, a legal adviser with the PLA Navy on a mission in Africa, briefed the media about the encounter. Jian Jiamin, now a prosecutor, said Chinese ships could take 'necessary measures to stop [these divers] until they exercise their right of self-defence'. This is a rather serious response to divers wearing underwater breathing devices, but the concern is growing. Recently, the U.S. Navy in Norfolk Naval base, Virginia, also encountered the "frogman shock" incident. The marine on duty found a man who they thought might be a diver on the wharf belonging to the forbidden area. The U.S. Navy sent out helicopters and ships to search the area, but no one was found until the blockade was lifted. Given the presence of more than 60 ships at the base (including the new 'Ford' aircraft carrier), this high level of vigilance makes sense.
These are extremely important military assets that cannot be destroyed. Frogmen engaged in espionage will not be welcomed by any military port naturally. They may be scouting and fortifying for future missions, or even leaving equipment in the port that can record the activities in the port. The microphone can collect information such as the amount of fuel added to the ship and the sound from the crew and engine, so that people may be able to judge the current activities of the ship. Umbilical cables containing optical fiber connecting the terminal and the ship may be bugged. The naval terminal will also use wireless communication systems, and these signals may also be intercepted. Compared to sabotage, intelligence gathering raises little concern. Just one diver can disable a warship by using explosive devices below the waterline.
The last time a frogman attacked a US ship was in 1964. At that time, only a few Vietnamese divers used the explosive devices attached to the ship's hull to bomb and sink the U.S. Navy's "Cadet" escort aircraft carrier, which was then used as a transport ship. There is no doubt that frogman is not invisible. If the navy is trained and wary of frogmen, many modern navy forces can use sonar to find these divers. The U.S. Navy can use special underwater grenades or even trained sea lions to stop them. Although unmanned underwater vehicles are taking over the exploration work of marine mammals, so far no robot has been able to track down divers like sea lions. But the last line of defense against the frogman is to be alert. Because despite the most advanced missile defense technology, stealth submarines and expensive fighters, several people wearing underwater breathing devices can make a ship feel worried.
