Type 210 icebreaker Yanbing

The Yanbing is a larger derivative of the Yanha class. It can carry out electronic intelligence, ocean tug, and icebreaking duties. "Sea Ice 723" ship was commissioned in 1982. It seems to be an enlarged type of three Yanha-class icebreakers that served beginning between 1969 and 1970. Its hull shape is indeed an icebreaker (it is said that its ice-breaking capacity is 1.2 meters at the maximum), but the upper layer The building has installed a large number of reconnaissance equipment such as electronic antennas, especially the two spherical radomes on the front centerline of the bridge. The characteristics of the collection of electronic signals are undoubtedly one of the main tasks. In the past, the ship also carried out a lot of water temperature measurement work. The ship has a full displacement of 4,420 tons, a length of 102 meters, a width of 17.1 meters, and a draft of 5.9 meters. The main engine is two diesel engines with a maximum speed of 17 knots, a double 37mm gun and a crew of 95 people.

For the Japanese, the most direct impression of the Chinese survey ship in recent years is that in May 2000, the "Sea Ice 723" ship crossed the Strait of Malay on the 14th of the month (the distance from the nearest time to the island was insufficient) 20 km), and it was on the 20th of the sea near the island of Mashima (also in the coastal area of Japan).

It then went north along the coast of the Japanese Sea on Honshu Island and crossed the Tsugaru Strait between Honshu Island and Hokkaido on the 23rd. (only 30 kilometers wide), in the beginning of June in the Tokyo Metropolitan Area near the Boso Peninsula activities, and finally returned to the coast of China from Okinawa on the 9th, in fact surrounded Japan for a week, and repeatedly entered the Japanese exclusive economy Area. In July of that year, during the Western G8 summit, the newly-served "East Tune 232" ship also carried out long-term activities near Okinawa.

After that, the Japanese government made representations to China and the two sides reached some agreements. However, it was not until October 2001 that the same "Sea Ice 723" ship crossed the Dagu Strait at the southern end of Kyushu Island and moved to the end of the month in the waters near Okinawa.

According to the Self-Defense Force, the "White Pelican" icebreaker was in charge of the ship. It is reported that during the course of the journey, the ship often stops or travels slowly. From time to time, some instruments are hoisted into the sea, and sometimes a sounding rocket of unknown use similar to meteorological rockets is regularly launched. It should be said that the various survey vessels enter and exit Japan's offshore and even coastal areas so frequently (basically all kinds of Chinese survey vessels are confirmed every month), which is quite meaningful, like "Sea Ice 723" in 2000.

In June, there are a lot of information that can't be received at home. For example, there are the Air Self-Defense Forces Bailey Base in the Tokyo area near the Boso Peninsula, the Fenggangshan Radar Station, etc., near the Tsugaru Strait. The Maritime Self-Defense Force’s large-scale local team headquarters and the Longfei Garrison, and other signals, will undoubtedly provide a lot of useful information. Moreover, the data on the temperature and current trends of the offshore waters in Japan have made China more aware of the situation between China and Japan, whether it is the development of resources and demarcation negotiations in peacetime), or the application of warships (especially submarines) during the war, will play an important role.

In February 1986, three cargo ships of China Ocean Shipping Company were frozen in Nanpu Port of Datong River in North Korea. After rushing to the country, Haibing 723 ship was ordered to rescue. At that time, the salt water in the port was 5 ‰, close to fresh water, the ice was hard, and the thickness of the ice layer was 1.5 to 1.8 meters. The icebreaker's maximum icebreaking capacity is 0.8 to 1.5 meters, which exceeds the ship's ability to break ice. At first they used the boat to collide with the ice, but the results were minimal. Later, I switched to reversing the boat and hitting the ice and the propeller, and stepping hard to get close to the trapped vessel. After 16 days of hard work, the rescue mission was successfully completed, and the company was awarded the power of the company and won the first class.

After the ship was retired, it was handed over to the Marine Police and renamed as China Marine Police 1411.
