After entering the 1950s, the military competition between the United States and the Soviet Union became more and more intense, and all countries on both sides hoped to gain technological superiority in the new round of arms competition, and the result was that countless high-tech technologies frantically poured into the military field. In addition, the countries on both sides are also eager to know what position the other side is in the arms race, and finally round after round of espionage warfare against each other is quietly unfolding, and this espionage war is particularly fierce underwater, because through their own submarines, they can directly contact each other's submarines, which is incomparable to taking several aerial photos, so the underwater chase is secretly unfolded in various oceans of the world.
▲The United States and the Soviet Union competed for hegemony
In order to curb the development of the Soviet submarine force, the Americans have used their geographical advantages to build an anti-submarine system in Europe since the 1950s, with the intention of curbing the passage of Soviet submarines out of the Atlantic. Therefore, within the U.S. submarine force at that time, tracking Soviet submarines and even forcing them to float became the goal pursued by various captains. Soon on May 28, 1959, Lieutenant Colonel Davis, the captain of the U.S. ss-525 grenadier diesel-electric submarine, encountered such an opportunity, when the captain was directing the submarine to conduct daily patrols in Icelandic waters, and suddenly sonar reported that a noise signal from the submarine's propeller was found, which attracted the attention of Captain Davis, and then the U.S. submarine began to track down the unknown submarine. During this process, the sonar of the US submarine has been able to catch a weak signal, and after 20 minutes, the signal suddenly disappeared.
▲ "Long tail cod" conventional submarine belongs to the United States Freshwater Carp class submarine, the class of submarines is a large number of submarines manufactured by the United States in the late World War II, after the end of World War II, the unfinished "long tail cod" temporarily stopped construction, and finally the boat was officially completed in 1951, sold to Venezuela in 1973
The brief encounter thrilled the captain of the U.S. submarine, which was most likely from the Soviet Union, and if he could force it to float and leave evidence, it would be a great victory for the entire U.S. Navy, and now the opportunity was in front of him. Then, according to the signal captured by the submarine's sonar, the US submarine estimated the course of the suspected Soviet submarine, and Captain Davis decided to take a gamble, increase the speed to reach the estimated route in advance and turn off the power unit, quietly ambushing and waiting for the "underwater guest". However, after waiting for a long time without any gain, soon the warm and high atmosphere in the boat gradually calmed down, and then evolved into loss and depression, is this submarine not taking this route, or has it already passed?
▲ A Soviet submarine surrounded and suppressed by the US military
Captain Davis then decided to float up, on the one hand, to change the already foul air in the cabin, and on the other hand, to search for the missing submarine through the radar's visual tools. Soon the submarine floated to the height of the periscope, the huge ventilation device began to work, and the submarine officers and men kept staring intently at the periscope, hoping to find the submarine, but the only thing waiting for them on the sea was the whistling sea breeze and the turbulent waves, and just when all hope was about to be dashed, the sonar soldiers caught a propeller noise signal, and at the same time there was a wave of uneasiness in the heart of Captain Davis, although the capture of the unknown submarine was restored. But no one can rule out whether their own submarines were exposed, or whether the American submarines intending to ambush were ambushed by "prey"?
▲ The sonar receiving array located at the head of the submarine, the launch array is generally below the submarine command module (as shown below), in order to avoid being discovered, the submarine generally only works in the receiving array when sailing underwater, and the launch array is used when necessary
So the captain decided to take a risk, and then the long-tailed cod began to make an emergency descent, firing an identification signal from the U.S. Navy, but received no reply. Instead, the submarine began to change course frequently as if frightened, while increasing its speed and trying to get rid of tracking. This was all too obvious: it was a Soviet submarine, and it had found itself being tracked. Captain Davis ordered sonar signals to be fired to clarify the specific orientation of the Soviet submarines. At this time, the Soviet submarines began to constantly change the navigation parameters and try to occupy a favorable position, but the preemptive American "Longtail Cod" submarine always occupied a favorable tracking position, so in one maneuver and contest after another, the American submarines, which knew that they were weak, began to call for nearby anti-submarine patrol aircraft to come to support, because in this area the US military has always firmly occupied the all-round advantage, and the Soviet submarines have almost no support.
▲ In the 50s and 70s of the last century, the S-2 anti-submarine aircraft served in the US military
Unwilling to sit still, the Soviet submarine tried to surface to report to the base and ask for support, but the anti-submarine aircraft that the US military had arrived long ago never gave him a chance, because once it floated, it meant becoming a prisoner of the US submarine, and the US submarine and anti-submarine aircraft took this opportunity to carry out an anti-submarine exercise, which was aimed at a real Soviet submarine. Perhaps knowing that there was no support, the Soviet submarine simply turned off its power and floated tightly in the sea to reduce the chances of detection. At this time, the US submarine also understood that this Soviet submarine could not carry for long, on the one hand, the command of anti-submarine patrol aircraft continued to search, on the other hand, the US submarine also turned off the power, and did not rush to send sonar signals to search for this Soviet submarine, because Captain Davis understood that the Soviet submarine could not float for a long time underwater navigation, and he could float out at any time to replace the air and recharge the battery, in addition, there were a large number of anti-submarine patrol planes nearby that could come to change shifts, and now they only needed to quietly wait for the Soviet submarine to surface on their own.
▲ Soviet Type 611 conventional submarine, is a type of large ocean-going submarine after the Soviet Union
At about 1 a.m. on the 29th, the Soviet submarine, which was "out of bullets", surfaced and wanted to replace the air in the cabin and charge the battery under the cover of night. However, the US submarines and anti-submarine patrol aircraft on the surface of the water have been waiting for a long time, and they can clearly see through the periscope: this is a Soviet Type 611 submarine (known in the West as the Z-class)! Soon a large number of photographs were sent to the U.S. Naval Command, and these photos confirmed, like ironclad evidence, that the Soviet submarine was forced out of the water by the American submarine, which meant that the Soviet submarine had become an iron coffin in wartime.
During the Cuban Missile Crisis, the B-59 submarine was forced to float, which made the Soviet Union lose face, and the captain and many people were strictly punished
After a short follow-up, the Long-tailed Cod was ordered to return to its post to continue the patrol, and the tracking task was transferred to the anti-submarine patrol aircraft, without the support of the submarine, the anti-submarine patrol aircraft quickly lost its target, but it did not matter to the "Long-tailed Cod", because just now they had achieved a major victory.
