Here are the most remarkable ones summarized by China Daily:

1. First fully China-made aircraft carrier

The Type 001A aircraft carrier or CV-17 is China's first totally domestic-made carrier based on research from Chinese aircraft carrier Liaoning, and was launched on April 26. The carrier was constructed by the China Shipbuilding Industry Corporation in Dalian. China joined the list of only 10 worldwide countries with a capability to produce aircraft carriers.

2. China’s first self-designed large airplane

C919 made its maiden flight successfully on May 5. It is China's first self-designed homemade airplane with independent intellectual property rights. C919 is a narrow-body twinjet airliner developed by Chinese aerospace manufacturer Comac, can carry up to 168 passengers and is intended to compete with the Boeing 737 MAX and Airbus A320neo. Comac already recieved 785 orders from 27 Chinese and overseas customers.

3. First X-ray astronomical satellite launched

"Huiyan", China's first X-ray astronomical satellite, was carried by CZ-4B and launched successfully on June 15, at the Jiuquan Satellite Launch Center. The data from this 2.5-ton Hard X-ray Modulation Telescope will be open to scientists all over the world. HXMT will help scientists better understand the evolution of black holes and the strong magnetic fields and interiors of pulsars.

4. New generation bullet train launched

China's new bullet train 'Fuxing' took its first ride on the Beijing-Shanghai line on June 26. 
'Fuxing' represents the next generation of bullet trains, able to go at the speed of 400 kilometres per hour, making it the fastest commercially run train. Core technology is Chinese-made.

5. 10,000-ton guided missile destroyer launched

The Type-055 destroyer (NATO code name Renhai) was launched June 28, domestically designed and produced guided missile destroyer, designed for air-defense, anti-missile, anti-ship and anti-submarine warfare. It is one of the most modern, multi-purpose warships that can be armed with weapons that are currently in development.

6. Semisubmersible drilling rig built

Blue Whale 1, the ultra-deep-water semisubmersible drilling rig, is built by China's largest semisubmersible platform manufacturer, China Yantai CIMC Raffles Offshore. It succeeded in collecting samples of combustible ice in the South China Sea on July 29. Blue Whale 1 is the world's most advanced ocean drilling platform design. The platform has the greatest operating and drilling depth in the world, and can operate in deep-sea operations across the world.

7. Three Yaogan 30-1 satellites placed into orbit

Yaogan satellites as intended for scientific experiments, land survey, crop yield assessment, and disaster monitoring, and are developed by the Shanghai Academy of Space Flight Technology. They were launched successfully on Sept 29, at Xichang Satellite Launch Center.

8. Manned submersible completes deep-sea testing

The manned submersible named Shenhai Yongshi, meaning “deep-sea warrior”, returned after completing all deep-sea testing in the South China Sea. It reached a depth of 4,500 meters to test functions and performance during an over 50-day expedition. It successfully returned to port of Sanya, Hainan on Oct 3.

9. Upgraded Chinese navigation satellite system launched

Two 3rd-generation Beidou satellites were launched on Nov 5, at Xichang Satellite Launch Centre. This is the first step of establishing a vast positioning and navigation network with global coverage. Beidou is the fourth navigation satellite system in the world, following the United States' GPS system, Russia's GLONASS and the European Union's Galileo. Beidou has brought huge economic and social benefit in the areas of transportation, fishery, hydrologic monitoring, weather forecast, geodetic survey, intelligent driving tests, mobile phone navigation, vehicle navigation and more.

10. Hong Kong-Zhuhai-Macao Bridge ready for traffic

The Hong Kong-Zhuhai-Macao Bridge is the longest sea crossing bridge in the world, which has profound meaning for Hong Kong, Macao and Zhuhai's economic and social integration. The bridge will cut travel time between Hong Kong and Zhuhai from three hours to just 40 minutes. Currently the construction of the Hong Kong-Zhuhai-Macao Bridge is in its final phase and expected to be completed by the end of December.
