Text 112. Guadalcanal (1)

Previous page        Return to Catalog        Next page

    Things have changed and stars have moved. On the other side of the earth, a bright moon hangs in the sky. It is rare to have such a calm night in the southwest Pacific.  On the sparkling sea, the silver moonlight shines on the low black boat that is passing through several waves.  The rolling waves flashed brightly on both sides of submarine No. 6332. The 18th Submarine Group of the 3rd Submarine Command of the 3rd Fleet was operating in the waters around New Caledonia.

    After several months of strangled sea and air battles, the U.S. military stationed on Guadalcanal Island has been greatly weakened. According to the combat plan of the Southwest Pacific Theater, the Navy is about to launch a final landing operation against the enemy.

    As the war progresses, the enemy's anti-submarine warfare capabilities have been greatly improved. As the latest radio detection devices are equipped in large numbers on escort warships and anti-submarine aircraft, the activities of submarine forces have been subject to greater restrictions.  The pre-Type 4 submarines equipped in the Republic Navy are now mainly used to perform daily patrols, reconnaissance and rescue missions during naval battles due to their limited concealment and diving depth. There are less than 400 of the latest Types 4 to 6.  Ocean-going submarines can also perform some attack missions, but most of the time, it is difficult to get close to the enemy's convoy fleet. The latest destroyers and frigates of the US military are equipped with advanced radar and sonar systems.  In sea areas, submarines will be discovered most of the time before they enter the attack position.

    The Republic Navy's latest Type 6 ocean-going attack submarine draws on a large number of excellent designs from allied countries. Like Germany's latest Type 21 submarine, they both choose a water-drop shape design with greater underwater concealment. However, since the Pacific battlefield requires more than the Atlantic battlefield,  With longer-term self-sustainability, the Type 6 submarine designed and built by the Republic Navy has a displacement of nearly 700 tons more than the German Type 21 submarine, and the corresponding endurance has increased to 19,500 nautical miles/10 knots.

    The standard displacement of Type 6 submarine is 2230 tons, the underwater displacement is close to 3000 tons, and the maximum diving depth is 280 meters. Large displacement is also a common feature of Chinese and American submarines. After all, the Pacific Ocean of more than 6000 nautical miles is much wider than the Atlantic Ocean.  .

    After learning from the experience and lessons learned in the war, the Republic Navy focused the design of new submarines on improving the survivability of submarines.  In view of the increasing threat from anti-submarine aircraft, the boat is equipped with a twin-mounted 30mm anti-aircraft gun, which has certain air defense capabilities in emergencies.

    Type 6 submarine has 6 bow torpedo launch tubes. What is different from previous types of submarines is that it uses an electric hydraulic automatic loading system, which can complete the reloading of 6 torpedoes within 10 minutes.  It also adopts the latest hybrid guidance electric torpedo of short-range wired guidance and sonar self-guiding.  Being able to carry out underwater submarine launch attacks greatly improves the submarine's attack capabilities.

    The hull of the Type 6 submarine is coated with a special coating that can absorb certain radar waves and ultrasonic waves, which greatly reduces the detection range of enemy ships' radar and sonar. Sonar receiving devices are installed at 16 parts of the hull.  A radar wave receiving antenna is installed on the underwater snorkel.  Able to detect enemy patrol aircraft and escort warships in a timely manner.  The newly designed five-blade propeller can greatly reduce the noise generated by the propulsion system. Due to its excellent underwater performance, the Type 6 submarine has strong attack power and high survivability.  When it is submerged at full speed at the depth of the underwater snorkel, its maximum speed can reach 23 knots, which is almost the same as the enemy's escort ship. The echo generated by the streamlined hull makes it difficult for the enemy warship to locate during detection, which makes it difficult for the enemy warship to locate.  Type 6 submarines are more likely to escape attacks from anti-submarine warships.

    The Republic Navy adopted the segmented construction method very early on to build submarines and light ships such as destroyers and frigates, which made the construction speed relatively much faster.  Since the construction of new submarines began in May 1943, by February 1944, 56 Type 6 submarines had been completed and put into service, most of which were deployed to the Southwest Pacific.

    Yang Jingwen has been promoted from the submarine torpedo commander in the early days of the war to the lieutenant colonel commander of the submarine detachment. This is something that is simply unimaginable in peacetime.  Since the war began, the number of Republican Navy submarines has increased sharply from 112 to more than 880. It currently has 7 submarine commands. In the Southwest Pacific theater alone, it has 2 submarine commands with a total of 286 submarines. The rapidly cooling submarine force is also a submarine force.  The main reason why officers are promoted quickly.

    ??In fact, throughout the war.  The navy's cooling speed is much faster than that of the army. The naval fleet has grown from the initial three fleets to the current six fleets. The number of ships it has has increased nearly 10 times. The size of the navy has increased from 435,000 tons of cold war at the beginning of the war.  At present, it has 6.37 million tons, and has 32 heavy fleet aircraft, 33 battleships of various types, 5 heavy cruisers of the fourth level, and a total of 67 cruisers of various types, 289 destroyers and 132 frigates of the sixth level.  In terms of the number of main combat ships, it is equivalent to that of the United States, but its quality is still superior.

    So far, the Republican Navy, including the Marine Corps and Naval Aviation, has 5.6 million personnel.  In terms of the number of soldiers, it exceeds that of the United States and Britain combined. The strong naval strength is the main factor that allows the Republican Army to maintain the initiative on various battlefields.  Corresponding to this is the RepublicMore than 65% of the annual military expenditure of more than 150 billion yuan is spent on the navy.  The annual consumption of more than 50 million tons of crude oil accounts for 70% of military fuel consumption.

    These are close to the limit of what the Republic can bear.

    Yang Jingwen and Wang Tao, the captain of the 6332 boat, were both standing on the bridge. The gunnery officer, Sergeant Yan Jingui, led the two crew members in raincoats up to the narrow rear deck to check the automatic rocket launcher.  The waves hit them hard, making it difficult for them to walk.  The moonlight shone clearly on the sea, and the other three submarines of the same team appeared on their sides like clusters of black shadows, appearing and disappearing in the waves.

    "Detachment leader, when shall we take action?" Wang Tao said to Yang Jingwen.

    "We are expected to arrive at the mission area around 4:30, and according to the order, we should launch the attack on time at 5 o'clock." The task of the submarine team is to attack the B-17 bomber base in Menua, which is an airport far away from the coast.  It's not far, but the task is not that simple.  This is the first time that a submarine force has carried out a ground attack mission. Although it has conducted several drills in this area, it is much more difficult to implement it in actual combat.

    The 200mm rocket launcher equipped by the Type 6 submarine will not cause great damage to the enemy's airport and will be repaired within a few days.  The combat plan in the theater is to gain a few days to reduce the air threat during landing. Of course, if some of the enemy's heavy bombers can be destroyed, that is the most ideal result.

    "That's it, follow the current course. I'll go to sleep for a while and call me again at four-thirty." Yang Jingwen said that there was nothing going on on the sea. There were still more than five hours of sailing from the target sea area. He needed to  Let's rest for a while. When it comes to fighting, we will not be at peace for several hours.

    "Okay, keep the current course, speed 15 knots, I understand!" Wang Tao said, he still needs to be on duty on the bridge for one hour.  Having just been promoted to the captain of a new submarine, he is full of desire for combat. Starting from the past year, the frequency of naval activities has dropped significantly, and no one has participated in combat for three months.
