Familiar recipe, familiar taste. Gunshots rang out at exactly six o'clock. Everyone quickly packed up and went out to gather.
Today's instructor is Blue Whale from the Jiaolong Commando. This instructor is good at underwater combat and has extensive experience in water combat.
All they saw were many unfamiliar firearms, diving equipment and other items placed before them, including a gun they had never seen before.
At this time, Blue Whale said: "Hello, my code name is Blue Whale. Your training mission today is underwater warfare. I will be the instructor of this subject. With the development of the times, underwater warfare is becoming more and more important. This subject is also something you must master. You will be exposed to many water combat scenarios in the future. Underwater special operations is the use of special operations forces to infiltrate from underwater to conduct reconnaissance and raids on enemy anchored ships, underwater facilities, offshore economic facilities, as well as coastal and land targets such as ports and bases. This form of combat has a natural concealment and can achieve greater results at a relatively low cost. It has a certain psychological deterrent effect on the enemy. Since World War II, it has been valued by the navies of many countries in the world. Many small and medium-sized countries even use it as an important asymmetric means to deal with powerful enemies."
At this time, someone asked: "Instructor, can we blow up the submarine?"
Blue Whale said: "Yes, there are cases of underwater combat forces blowing up submarines. A five-man American frogman team used explosives to blow up an attack submarine with more than 100 people. That battle directly scrapped a submarine, and only more than 20 people survived. It can be said that the frogman team won a great victory. In fact, there are many underwater combat cases, all of which are victorious with fewer troops, which is enough to show the importance of underwater combat. Let me first explain to you the current development situation. Naval underwater special warfare platforms mainly refer to platforms used by the navies of various countries to carry out special warfare missions such as frogman underwater delivery, reconnaissance and attack. In peacetime, they can be used for underwater security and rescue tasks. They can be roughly divided into frogman carriers, frogman transport boats, submarine dry deck shelters, special warfare submarines, special warfare UUVs, etc.
Second, frogman transport vessels refer to larger underwater platforms used to transport frogman special operations teams or squads of frogmen. Based on the method of underwater transport, they can be divided into two categories: wet frogman transport vessels (SDVs) and dry frogman transport vessels (DCSs). Based on the propulsion mode, they can be further divided into underwater transport vessels and surface/underwater hybrid transport vessels. Wet frogman transport vessels, developed based on the "man-operated torpedoes" of World War II, are used to transport a squad of frogmen and their accompanying equipment from long distances to near-shore underwater special operations platforms. They can be deployed from platforms such as submarines, surface ships, and aircraft.
The most typical wet frogman transport boat at present is the MK-8 MODI, which was developed by the U.S. Navy in 1975. It is 6.7 meters long and has a range of about 70 nautical miles. It can carry 6 fully armed frogmen (including 2 pilots and 4 frogmen). The cabin is completely submerged in water and can be secretly transported to the target area by U.S. Navy submarines and DDS. It can also be delivered by combat support ships and C-130 Hercules transport aircraft.
A "dry" frogman transport boat is a dry, normal-pressure combat submersible. Its underwater weight is usually around tens of tons, its length is less than 20 meters, the cabin is at normal pressure, and it can carry several to more than a dozen frogmen and their equipment.
The surface/underwater dual-purpose frogman transport boat is a frogman transport platform that has the dual functions of high-speed surface navigation and covert underwater maneuvering. It can carry special forces personnel to perform high-speed maneuvers on the surface to the vicinity of the target area and then dive underwater to transport personnel covertly from underwater to the target area to carry out special operations.
The submarine dry deck shelter (DDS) is a special cabin installed on the submarine for transporting frogmen and vehicles. It is usually installed behind the submarine command room enclosure and is connected to the submarine by a special passage. Frogmen can enter and exit the submarine through the passage, and can leave the deck dry cabin with the frogman vehicles to carry out missions or withdraw.
Special operations submarines usually refer to miniature submarines with a displacement of less than a few hundred tons, which are specially used for underwater infiltration and sabotage special operations missions. In addition, some countries modify their active submarines or add special operations payload modules when designing new submarines to conduct or support special operations, which can also be classified as special operations submarines.
Special operations UUVs are unmanned underwater platforms capable of carrying out special operations missions such as reconnaissance, raiding, and transport. Special operations UUVs are specialized underwater platforms used for special reconnaissance, raiding, and jamming. UUV technology has rapidly advanced in recent years, with micro-UUVs being particularly portable by special forces and often used for covert, close-range reconnaissance and raiding operations. Reconnaissance UUVs can carry imaging sonar and oceanographic sensors to conduct imaging reconnaissance of enemy ports or coastal shoals, acquiring seafloor and hydrological and meteorological data, providing crucial intelligence for command and decision-making.
Second, the development trend of underwater warfare:
1. Flexible three-dimensional delivery through the mother platform
Due to limitations in size and energy systems, frogman underwater special operations platforms generally have a limited range and combat radius. Relying solely on these platforms for combat is not very effective; they require long-range delivery platforms such as submarines, surface ships, and aircraft to be deployed. Therefore, when developing these platforms, the world's major military powers simultaneously consider the issue of long-range delivery from various mother platforms.
