The very good-looking submarine warfare movies have the shadow of "Red Tide Storm" and "Hunting Red October".
The sound effect of active sonar is similar to howling wolf, so the name of the movie is the song of wolf
The non-cancellation after launch is to ensure nuclear strike capability:
The core idea of nuclear deterrence is "equal to ensure destruction." Both parties in the Cold War had a reliable second nuclear strike capability, that is, after the other party first carried out a nuclear strike, oneself could still survive and had the ability to completely destroy the other party's nuclear retaliation.
In the movie, the strike command assumes that the homeland has been destroyed and communications are also controlled by the enemy. In order to ensure nuclear retaliation, any cancellation of the order is regarded as an enemy.
Ultra-quiet strategic nuclear submarine:
The French strategic nuclear submarine has always been in a leading position in the world and is a major component of the country's strategic nuclear deterrence.
The "Awesome Class" is the first generation of French ballistic missile nuclear submarines, all of which have been decommissioned. There are a total of 6 Awe-inspired-class ships. During the Cold War, they kept two patrolling at sea at any time and were able to perform all-weather alert missions.
The most advanced strategic nuclear submarine in active service in the Navy is the Triumph class. The noise level is comparable to or even lower than that of the Ohio class of the United States, about 1/3 of that of the Dreadnought class strategic nuclear submarine. The sound of its sailing can be fused with the sound of the waves.
French F17 line guided torpedo:
After the wire-guided torpedo is launched, it is directly controlled by the submarine, which can always guide the torpedo to attack the target, and any torpedo jamming equipment will not work.
The best way to counter the wire-guided torpedo is to launch the torpedo too, and then try to see who cuts the wire first to avoid it. Therefore, we can see that the crew members who stopped the submarine have been demanding to cut off the wire to evade.
Fourier transform harmonic analysis:
The male protagonist found it in a bookstore. To me something like a heavenly book.
The rough meaning is: any periodic signal can be expressed as a series of "harmonic relations" of the superposition of sinusoidal signals.
The Jamalan destroyer is a frigate according to Western standards:
The Jamalan destroyer is completely independently developed by Iranian experts. It is a technological breakthrough in Iran's military industry. As a multi-purpose high-speed warship, it can simultaneously fight enemy submarines, aircraft and ships under radio and electronic warfare conditions.
