From China Power, CSIS: “Five years after commissioning its first aircraft carrier, the Liaoning, China is now primed to launch its second carrier – the Type 001A. Unlike its Soviet-built predecessor, the Type 001A is China’s first domestically built carrier. Both carriers are similar in size and use a STOBAR (Short Take-Off But Arrested Recovery) system for the launch and recovery of aircraft. Although similar to the Liaoning, the Type 001A features some notable enhancements and represents an important step in China’s developing aircraft carrier program.”
By Robert Farley, Jalopnik: “There's a lot of consternation about whether or not the United States should even have massive supercarriers anymore. Obviously, the answer here is "depends on how much explosives you've got." But while sinking an aircraft carrier is difficult, it's not impossible. The key is what it's used for, and who it's used against. But if you wanted to sink one, here's what you'd have to do, and what you'd be up against."
