Since the first ship of the Navy 055 missile destroyer 101 Nanchang ship completed a joint exercise with the Russian Pacific Fleet in the waters near the South Kuril Islands at the beginning of this month, the US Navy finally announced the latest movement trajectory of the Nanchang ship, and also predicted in advance that the Nanchang ship's next step is likely to go to the United States' strategic location in the central Pacific - the Hawaiian waters. There is nothing to say about

. After all, since the 101 ship was put into service, it has appeared in front of the United States for more than once or twice. However, in the news reported by foreign media, a seemingly common problem was discovered: the 055 missile destroyer had a full load displacement of 12,500 tons. The huge hull not only has a wide flight deck, but also a dual hangar. Moreover, the carrier-based helicopter that will be carried by the 055 is the anti-submarine type of the new generation of the Z-20 10-ton helicopter developed by my country. However, from the first ship of 101 to the 102 Lhasa ship, 103 Anshan ship, 104 Wuxi ship, 105 Dalian ship, 106 Yan'an ship, and 107 Zunyi ship and 108 Xianyang ships that are currently in service, carrier-based helicopters that are currently carrying or have undergone take-off and landing tests are generally Z-9D carrier-based anti-submarine helicopters with a maximum take-off weight of only 4.5 tons.

only 102 Lhasa ships have previously conducted take-off and landing tests of the Z-20 carrier-based type. Among the remaining ships, there are both those that are generally equipped with Z-9D, and those that are tested with card-28 anti-submarine helicopters. So what causes the Zhi-20 ship-based model to appear long ago, but the several 0.55 million tons of large-wheel drives that were in service in batches were not equipped with the Zhi-20, but instead equipped with the Zhi-9D that was not owned?

1. The official publicly reported the scene of the ship-based Z-20 for practical training, but judging from the official reports, the warship that took off and landed was not a 055 missile destroyer, but a 052DL missile destroyer. Moreover, the Z-20 that takes off and lands is not an anti-submarine type equipped with the standard missile destroyer, but a general type that is commonly used in aeronautical vertical landing operations.

So it can be seen from the official report that the Z-20 took off and landing flight training from a certain type of destroyer , and is likely to be just a short take-off and landing test, and abnormal batch equipment is in service. , and the ship-based Z-20 has not only the Z-20 general type that has been in service in batches, but also has anti-submarine type that is full-time equipped on the destroyer. However, the carrier-based Z-20 has been in service, and the carrier-based Z-28 anti-submarine type has not yet been in service. Therefore, the 055 warships that have been in service in batches can only carry the Z-9D anti-submarine helicopter, or the ship-mounted carries the Ka-28 anti-submarine helicopter.

2. Of course, the reason for the first point is not absolute, but for the full-time combat destroyers such as 055 and 052D, the helicopters carried do not need to participate in vertical landing operations, but mainly to complete maritime search and rescue and long-range aviation anti-submarine operations. Even if the carrier platform of the anti-submarine helicopter is different, the aviation anti-submarine and search and rescue equipment they carry are also different. In particular, during the anti-submarine combat process, it is necessary to communicate information on the anti-submarine search and rescue range, the enemy situation and other information in real time, and communicate with the mothership through the data link at the first time, which further increases the difficulty of the development of the anti-submarine Z-20 and the test cycle on board.

That is to say, although the Z-20 carrier-based model has appeared, because the anti-submarine type is more difficult and requires a longer period of sea trials, the Z-20 carrier-based general-purpose model has been in service, and the Z-20 anti-submarine type has not yet been in service. Therefore, the 055 missile destroyer that needs to complete the aviation anti-submarine search and rescue training of carrier-based helicopters can only use the Z-9D anti-submarine helicopter to charge the number first.

Of course, for the current 055, the pressure on helicopters to participate in anti-submarine operations is not great. After all, 055 is equipped with a variety of medium and long-range anti-submarine equipment, and helicopters do not need to perform anti-submarine operations in combat readiness patrols, so it is completely enough to play the following 9D at the take-off weight.But in the long run, the Z-20 with a larger take-off weight is more fragrant. After all, the Z-9D in service is limited in its take-off weight, and after a single aircraft is equipped with anti-submarine equipment, it cannot carry a large number of anti-submarine weapons such as torpedo . It can only have one anti-submarine search and one launches torpedo based on information to perform anti-submarine use. The two partners have undoubtedly delayed the fighter's fighter. In contrast, the Z-20 with a maximum take-off weight of 10 tons can complete submarine search and anti-submarine combat at the same time.
