Improved arsenal

In the past year, the Navy commissioned the nation's largest supply vessel－the first Type 901 class comprehensive resupply ship－enabling the Liaoning carrier battle group to sail farther away. Military observers said the ship displaces more than 45,000 metric tons, making it almost two times heavier than the Type 903 class, now the pillar of the Navy's supply force.

The country's first domestically designed aircraft carrier, launched in April 2017, completed its maiden sea trial last week.

The ship, the largest and most sophisticated naval vessel in China, displaces at least 50,000 metric tons and has stronger fighting capabilities than the Liaoning. Analysts anticipated that it will be delivered to the Navy within a year if sea trials are successful.

The Navy is expecting delivery of a 10,000-ton guided-missile destroyer, widely believed to be the mightiest of its kind in the world. The first in the Type 055 class, the destroyer carries over 100 vertical launch cells capable of firing air-defense, missile-intercepting, anti-ship and anti-submarine missiles. Several Type 055 ships are under construction, and the first is expected to soon begin its first sea trial, according to media reports.

Navy researchers also have developed electromagnetic launch technologies that give Navy ships a futuristic, game-changing weapon－an electromagnetic railgun. Experts say the weapon is capable of revolutionizing future naval warfare with power, range and speed far superior to explosive-powered guns.
