Here with the Chinese answer to the MQ-25?

PL-XX!

"How China's New Missile Concept Could Cripple American Air Power"

"The PL-XX has an very long range [air-air missile] to target the tankers and other support aircraft that form the backbone of American air power."

"PL-XX appears similar in concept to the Soviet K-100 missile. Developed by Novator, the K-100 was unique among air-to-air missiles in being a two stage missile, using a booster rocket from the ground-based S-300 surface-to-air missile to give it range of 186 miles."

With regard to the K-100: "The Novator KS-172 is a Russian air-to-air missile designed as an 'AWACS killer' at ranges up to 400 km. [250 miles]. The missile has had various names during its troubled history, including K-100"

A CHINESE AIR-AIR MISSILE AS USED TO INTERCEPT AND DESTROY AT LONG-RANGE AMERICAN AEW [Airborne Early Warning], AWACS [Airborne Warning and Control System], AND TANKER WARPLANES. TANKERS TO INCLUDE CARRIER-BORNE MQ-25.

Deny the American aircraft-carrier combat aviation units in a Sea-Air battle access to air-refueling tankers and you have a war-winning measure for the Chinese?
