According to foreign media reports, Japan’s Mitsubishi Heavy Industries recently released the concept design of the next-generation new attack submarine. The submarine is named "29SS". Canglong-class submarine, this kind of sci-fi underwater warship will ensure that Japan maintains its reputation as "the quietest and most modern non-nuclear-powered submarine in the world." Although Japan and Russia have had long-term territorial disputes over the "four northern islands", many Japanese experts have clearly stated that Japan's upgrading of conventional submarines is not directed at Russia.
Although the replacement of conventional submarines is not aimed at Russia, it does not mean that Japan does not pay attention to Russia’s defense. In the 2014 edition of the defense white paper, Japan not only made China a “key focus” and emphasized the threat of China’s maritime development strategy to Japan, but also emphasized that Russia’s activities around the Japanese archipelago have become more frequent. The Abe regime first proposed the "Russian Threat Theory." The white paper shows that the number of emergency lift-offs by the Japanese Air Self-Defense Force against Chinese and Russian military aircraft increased sharply in 2013, breaking the 800 mark for the first time in 24 years. Japan responded to Russia’s The number of emergency lift-offs shows the relationship between Japan and the Moscow leadership. Compare President Putin’sDuring the first and second terms, Russia’s air activity increased significantly during its third term. During the first two terms of office, Putin made domestic reconstruction his top priority. Russia's recent aerial activities also reflected the country's economic growth and domestic stability.
Facing Russia, which has a relatively strong military strength itself , Japan also replaced its first two by F-4 "The F-35 stealth fighter flight team, which has retired from the "Phantom" fighter, is deployed at the forward base close to the disputed islands of Japan and Russia-the Misawa Air Self-Defense Force base in Aomori Prefecture, northeastern Japan. F-35 deployment and patrols will be effectively checked and balanced. Russia’s aerial activities in northern Japan. However, Japan, which has a limited defense budget, must also consider the cost of using such an expensive fighter to perform emergency lift-off missions, as well as Russia’s strong interest in collecting F-35 signal characteristics. On the other hand, Japan is anxious to quickly develop and grow the F-35 team to fight against Chinese and Russian fighters. This can also be said to be an important indirect cause of the crash of the first Japanese F-35A fighter in the Sea of Japan. Although the cause of the F-35A fighter plane’s crash was attributed to the pilot’s “space fascination”, various Japanese media strongly questioned this, believing that it would not take self-defense to go around the F-35 before fully investigating the cause.The lives of the players are serious.
The former US Pacific Command (now the Indo-Pacific Command Dennis Blair, the retired admiral of ), suggested that Japan should pursue a policy of "strategic silence". He believed that Japan needs to be patient and strategically ignore some aircraft operating near its airspace. For example, when the Air Self-Defense Force identifies a neighboring country’s reconnaissanceMachine, then you can choose to ignore it. Although this seems to be detrimental to Japan's security, the United States has responded to Russia in this way in terms of homeland defense. For Putin, who holds the Tu-160, Tu-22M3 and other strategic bombers, sending Tu-95 around Japan is nothing more than a "beating operation." Japan has developed several conventionally powered submarines, even if it is aimed at Russia. Will not be put in his eyes.
