The Japan Maritime Self-Defense Force has been doing math problems for the People's Liberation Army Liaoning ship since December 17, because the Japan Maritime Self-Defense Force has adopted an all-day tracking and surveillance strategy to collect 100% statistics on the Liaoning ship's carrier-based aircraft takeoff and landing data. The Japan Maritime Self-Defense Force used a relay method as early as May to conduct statistics on the takeoffs and landings of carrier-based aircraft of the PLA Liaoning ship, and finally concluded that the J-15 fighter jets of the Liaoning ship have a frequency of 25 takeoffs and landings per day. The PLA's J-15 fighter jets' 25 sorties per day have reached the take-off and landing level of the US Navy's Ford-class aircraft carrier. In fact, the Japanese statistics are only for reference, because the Liaoning ship is conducting long-sea training activities and is not entering combat mode.

The Japan Maritime Self-Defense Force announced new takeoff and landing data for the People's Liberation Army's J-15 fighter jets on December 21. According to Japanese statistical data, it can be seen that the average number of takeoffs and landings of J-15 fighter jets at this stage is 15 per day, which is much lower than in May. The Japan Maritime Self-Defense Force used the DD104 Kirisame guided missile destroyer to track and monitor the PLA Liaoning ship throughout the entire process. The Kirisame guided missile destroyer belongs to the Murasame class that is heavily equipped by the Japan Maritime Self-Defense Force. This is a platform that Japan equips at the same time as it equips Aegis guided missile destroyers. Its comprehensive combat readiness capability is much worse than that of Aegis guided missile destroyers.

The Japan Maritime Self-Defense Force did not use the cutting-edge Maya-class Aegis guided missile destroyer to track and monitor the People's Liberation Army Liaoning ship. In fact, Japan is now struggling because when Japan uses the Kirisame guided missile destroyer, it can only track and monitor the Liaoning ship and cannot take into account other warships. In the face of the freedom of coming and going of the People's Liberation Army's 0.55 million-ton large-scale cruiser, Japan has no way at all. It can be said that Japan has kicked the iron plate. According to data released by Japan, the Japan Maritime Self-Defense Force discovered the 0.55 million-ton cruise ship on December 17 and December 21. The rest of the time, the movement of the 0.55 million-ton cruise ship was not known at all.

The 0.55-million-ton cruise ship discovered by Japan is also incomplete, because the People's Liberation Army has two 0.55-million-ton cruise ships accompanying the operation. The 0.55-million-ton cruise ship discovered by Japan on the 17th and 21st is not the same ship. Judging from the passive situation of the Japan Maritime Self-Defense Force, the stealth capability of the PLA's 0.55 million-ton cruiser has been tested. The PLA's 0.55-million-ton cruiser is constantly interspersed. It can be said that Japan is playing around. When counting for the Liaoning ship, beware of the sudden appearance of the 0.55-million-ton cruiser. The 055 is the most advanced guided missile destroyer of the People's Liberation Army. One batch has an equipment scale of 8 ships. The 055 represents the highest level of guided missile destroyers in the world.

Japan only uses one guided missile destroyer to track the People's Liberation Army aircraft carrier formation because the People's Liberation Army is dispatched in multiple ways. The Japan Maritime Self-Defense Force also uses other destroyers for tracking and monitoring. According to information released by Japan, the People's Liberation Army has at least 12 warships operating in the waters east of Japan. Obviously Japan cannot send 12 destroyers to track the People's Liberation Army. 202212279/ Global Defense Observation/Ali, Japan has had the largest maritime power in Asia for a long time in the past, but today the Japan Maritime Self-Defense Force no longer has the advantage. Whether it is the scale of equipment or the level of technology, it is far behind the People's Liberation Army. Just like the comparison of economic strength, Japan is no longer able to make a difference.
