Japanese media pays attention to the breakthrough of noise reduction technology of Chinese submarines: the noise is close to the ocean background sound.

Unsatisfied with the progress of China's submarine quieting technology, Japanese netizens left sarcastic comments: "Are you still stir-frying with an iron pot?"

Recently, Japanese netizens are discussing a South China Morning Post report about the advancement in China's submarine technology and the significant reduction in noise. Many Japanese netizens expressed envy and jealousy. One commenter even asked if China’s submarines were still using iron pots for cooking. Some Japanese netizens mentioned that they don’t know how far China can go, but no matter how quiet the submarines are, escaping from the Japanese Self-Defense Forces is impossible.

In fact, the early Type 091 nuclear submarines had a noise level as high as 160 decibels, which was mocked by the U.S. Navy as "underwater tractors." The new Type 093B nuclear submarines, through the pump jet propulsion system, terbium-dysprosium-iron alloy sound-absorbing tiles, and axialless pump push technology, reduced the noise to approximately 118 decibels, approaching the level of ocean background noise.

In 2018, when the Type 093B nuclear submarines passed through the Miyako Strait, the Japanese Self-Defense Forces' anti-submarine aircraft failed to effectively track them throughout the journey and were forced to admit their "ignorance" of the Chinese submarines' movements. This incident was called by Japanese media as the "humiliating turning point" in the 26-year tracking history.

From 1974 to 2000, Japan, relying on the geographical advantage of the first island chain and U.S. technical support, had real-time control over the movements of China's submarines and even publicly disclosed their sea departure coordinates. Nowadays, the passage of Chinese submarines through key waterways has become routine, and the Japanese anti-submarine network has been repeatedly penetrated.

The Pentagon's report even admitted that the performance of the Type 095/096 nuclear submarines "rivals the most advanced models of Russia." These assessments further stimulated anxiety among Japanese netizens. The comments like "cooking with an iron pot" are actually the Japanese netizens' instinctive reaction to China's military technology surpassing them.
