Macau-based military analyst Antony Wong Dong said the Type 055 had some “disappointing” design flaws. The relatively low positioning of its flat-array radar system would affect its range of detection, he said, while the use of light aluminum alloy in the upper decks would make it vulnerable to damage.

“Despite its very modern stealth shape, the damage control capability is a big concern,” Wong said. “The design follows the Chinese convention, probably due to a lack of experience ... in a combat situation.”
