China is building its second aircraft carrier and it swears this time the tech is going to be 100 percent pure People’s Republic.

The country is in the middle of a major military buildup but has been accused of basing its new designs on stolen technology. China’s air force has a few planes especially familiar to Lockheed Martin’s F-35 and Northrop Grumman’s X-47B unmanned combat air vehicle, with some of the designs likely stolen by cyber spies. Military analysts are keeping watch on companies like IBM that do big business with both the army and in China and which might be unwittingly providing Chinese hackers a backdoor into U.S. tech secrets.

China’s sole aircraft carrier was purchased as an incomplete hull from the Ukraine more than a decade ago then finished by its new owners. The country’s sudden buildup has been a cause for international tensions but remember the U.S. still has 10 times as many operational aircraft carriers — even if we only have 10 operational aircraft carriers. Anyway, none of this will matter in a few years when even small fishing boats can carry full drone battalions.
