It's not good.
At the Washington Post, "Confidential report lists U.S. weapons system designs compromised by Chinese cyberspies":
Designs for many of the nation’s most sensitive advanced weapons systems have been compromised by Chinese hackers, according to a report prepared for the Pentagon and to officials from government and the defense industry.Also, at Foreign Policy, "DOD says don't worry about hackers accessing key U.S. weapons designs."
Among more than two dozen major weapons systems whose designs were breached were programs critical to U.S. missile defenses and combat aircraft and ships, according to a previously undisclosed section of a confidential report prepared for Pentagon leaders by the Defense Science Board.
Experts warn that the electronic intrusions gave China access to advanced technology that could accelerate the development of its weapons systems and weaken the U.S. military advantage in a future conflict.
The Defense Science Board, a senior advisory group made up of government and civilian experts, did not accuse the Chinese of stealing the designs. But senior military and industry officials with knowledge of the breaches said the vast majority were part of a widening Chinese campaign of espionage against U.S. defense contractors and government agencies.
The significance and extent of the targets help explain why the Obama administration has escalated its warnings to the Chinese government to stop what Washington sees as rampant cybertheft.
In January, the advisory panel warned in the public version of its report that the Pentagon is unprepared to counter a full-scale cyber-conflict. The list of compromised weapons designs is contained in a confidential version, and it was provided to The Washington Post.
Some of the weapons form the backbone of the Pentagon’s regional missile defense for Asia, Europe and the Persian Gulf. The designs included those for the advanced Patriot missile system, known as PAC-3; an Army system for shooting down ballistic missiles, known as the Terminal High Altitude Area Defense, or THAAD; and the Navy’s Aegis ballistic-missile defense system.
Also identified in the report are vital combat aircraft and ships, including the F/A-18 fighter jet, the V-22 Osprey, the Black Hawk helicopter and the Navy’s new Littoral Combat Ship, which is designed to patrol waters close to shore.
Also on the list is the most expensive weapons system ever built — the F-35 Joint Strike Fighter, which is on track to cost about $1.4 trillion. The 2007 hack of that project was reported previously.
Well, it feels like we're back in the Cold War.
But no worries, the Obama administration has everything under control!
