The first stage 075 sea trial was successfully completed
Although the 075 is the first large-scale amphibious assault ship built by my country, thanks to my country’s strong shipbuilding capabilities and the considerable progress made in the field of ship construction in recent years, as well as the accumulated rich experience base, 075 is not only very fast in construction Fast, the overall technology is also very mature and stable. 075 can be regarded as my country’s experimental ship for amphibious assault ships, which is equivalent to the role of the No.17 aircraft carrier. With the foundation of the 16 and 17 aircraft carriers, my country immediately launched the construction of 80,000-ton aircraft carriers, and after the two 075s , There is already a new generation 076 amphibious ship construction plan.
The first 075 amphibious assault ship
On the first day of the National Day holiday on October 1, the first 075 amphibious ship left the shipyard wharf again to start the second phase of the sea trial. A few days ago, the media announced that the first phase of the first 075 sea trial has been completed. All completed, and all performance indicators have reached expectations, the overall performance is very good!
075 mast part
Amphibious ship sea trial period is shorter than destroyer
The 075 amphibious ship has a full load displacement of 40,000 tons. This displacement is equivalent to two 071 dock landing ships, which surpasses many light aircraft carriers and is about to approach the No. 16 aircraft carrier. The construction speed of such a large ship is so fast. In addition to the support of my country’s shipbuilding capabilities, the structure of the amphibious assault ship itself is not complicated. 075 can be regarded as an enlarged version of the 071 landing ship with through-deck, rather than Ships like medium-sized aircraft carriers.
075 started the second phase of sea trial
Combat ships such as destroyers and cruisers need to install mid-range and long-range air defense systems, anti-ship and anti-submarine systems, ship-based command and radar warning systems in addition to hull manufacturing. The overall construction complexity is higher than that of amphibious assault ships. Since there are many subsystems that need to be tested one by one in the sea trial, the sea trial process of destroyers and cruisers is longer. Since the 075 amphibious assault ship does not have many subsystems, its entire sea trial period is shorter than that of destroyers. The 075 in the second phase of sea trials may soon complete all the tests and enter the service stage.
The first 075 to blacken the back of the mast
The mast brushing black does not affect the appearance
The sea trials of new-built ships have two purposes. One is to test whether the performance of the ships meets expectations, and the other is to find the shortcomings of the new ships and improve them so that they can serve in the best condition. Careful netizens will find that after the completion of the first phase of the sea trial, the first 075 had all the back of its main mast blacked out. This is because the 075 diesel engine had relatively thick smoke at the beginning of the start, which formed smoke on the main mast. This short-term smoke has no effect on the performance of the ship, but the smoked main mast does not look very coordinated, so the simplest method of blackening solves this problem.
The mast of the 054A is also blackened
Blackening the main mast to solve the smoke problem was not the first in 075. For example, the British Navy’s Type 45 destroyer also found this problem in sea trials, so the main mast was also blackened, which is reminiscent of the last century. In the aerospace boom, in order to solve the problem that the pen core cannot be used normally in the low-gravity environment of space, the United States has developed a micro-pump to add to the pen core, and the Soviet Union's solution is to use a pencil directly! Brushing black directly on the mast of 075 is simpler and more effective than raising the height of the chimney, and it does not affect the appearance, just like the mast of the 054A frigate, but the appearance is still high!
