ocean carrierThere were many types of maritime transport ships with different functions and characteristics.
For example, a semi-submerged ship could adjust its own water to allow the loading deck to dive into the water, lowering the center of gravity of the cargo, reducing the inertia of the cargo itself and the impact of wind resistance and wave resistance on the hull, thus greatly improving stability. The cargo could float from the designated location to the loading deck and be transported to the designated location. Although most semi-submerged ships had power systems, they were rarely opened during operation. For example, Huayang 1 was towed by five tugboats during transportation, and its power was directly closed.
In terms of liquefied natural gas (liquefied natural gas) carriers, the 175,000 cubic meters of liquefied natural gas carriers developed and built by China's shipbuilding company, China's shipbuilding company, had a total length of 295 meters, a width of 46.4 meters, and a total cargo hold capacity of 175,000 cubic meters. The full-load transportation capacity could meet the needs of the entire Dalian City for one and a half months. It was the world's mainstream ship type and could dock at most of the world's large liquefied natural gas shore stations. It had excellent port adaptability and ship-shore compatibility.
Among the oil tankers, there was once the world's largest oil tanker, the Sea Giant, built by Japan. It was 458 meters long, nearly 60 meters wide, and had a displacement of more than 820,000 tons. However, in the context of the attack on the ship in the war between Iraq and Iraq, it was sunk by the MiG- 23 fighter jet of the Iraq Air Force on May 14, 1988.
There were also general cargo ships for transporting construction vehicles, such as the five-cabin four-crane general cargo ship with a length of 190 meters, a width of 32 meters, and a deadweight of more than 50,000 tons, which could carry construction vehicles and fuel tankers.
In addition, the 400,000-ton ultra-large ore carrier, Yuanjinhai, had a total length of 362 meters, a width of 65 meters, a depth of 30.4 meters, a structural draft of 23 meters, a speed of 14.5 knots, and a deck area equivalent to three football fields. It was a new generation of green, environmental protection, and energy-saving ultra-large transport ships.

Century-old aircraft carrier, Indian aircraft carrierIndia's aircraft carrier development process had many unique features. After the Republic of India was established on January 26, 1950, it established a naval fleet. Although its national strength was limited, it was interested in the ability of aircraft carriers in the ocean and naval battles and was committed to realizing the "aircraft carrier dream."
India currently has two aircraft carriers, one of which is the Vikramatia purchased from Russia. The purchase price is $1, but the modification cost is $3 billion. On April 26, 2019, the Vikramatia caught fire, killing a naval officer. The other was the Indian ship, the Vikrant. The reason why the aircraft carrier Vickland would kowtow step by step during the trial was that the lack of a bulbous bow could not counteract the vortex, and the hull would rise and fall with the waves. Moreover, the staff of the aircraft carrier painted the deck as bright as a mirror, which was not conducive to the stable docking of the aircraft.
The Indian-made aircraft carrier was 260 meters long and 60 meters wide. It was equipped with four general LM2500 gas turbine engines with a total power of 80 megavolts. It was propelled by two axes. Its speed was expected to reach 28 knots. Its designed endurance was 7500 nautical miles and its self-sustaining power was 45 days. It was planned to carry a total of 30 carrier-based aircraft, including MiG-29K, Ka- 31 helicopters and Indian-made LCAs. It would take off and block the landing. The flight deck was equipped with two take-off and taxiing routes and three sets of landing arresting devices.
India faced many problems during the construction of the aircraft carrier. For example, the first prototype of the carrier-based "Glory" fighter aircraft failed to obtain flight approval due to structural problems, resulting in delays in the service period of the aircraft carrier. India had many shortcomings in the manufacturing of weapons and equipment, and these shortcomings were also reflected in the equipment related to aircraft carriers. Although its domestic aircraft carriers were in service, they had not yet formed combat effectiveness. India relied on imported many key equipment in the construction of aircraft carriers, such as blueprints from France and Italy, gas turbine from the United States, electronic systems from France, special steel from Russia, ship-borne air defense missiles and radars from Israel, and naval guns from Russia. The large L-band air warning radar came from Italy.
Now, India announced that it would build a third aircraft carrier. However, given India's past performance in weapons and equipment manufacturing, such as the inability to produce ammunition, poor quality, and misfiring in the production of the Insus rifle, the instability of the Arjun tank caused by the manufacturing of the Arjun tank, the high failure rate, and the difficulty of maintenance, as well as the unpredictable impact point of the Agni missile, the Indian Navy may lack confidence in building a third aircraft carrier.
