The Lockheed Martin F-35 Lightening II is a stealth fighter jet that will fly with three different branches of the US military. While the work on this new jet is moving along and it may see service sooner than expected in some branches, military officials have recently told Congress that the US lead in stealth military technology is eroding faster than anticipated.

Air Force Lt. Gen. Herbert Carlisle cited aircraft like the Chinese J-20 fighter jet and the Sukhoi T-50 PAK-FA that is being developed in Russia as some of the aircraft that are challenging the American lead in stealth fighters. The US has held a leadership position in stealth technology since 1970 with the development of the F-117, but Carlisle noted that other nations are quickly developing this technology.

The Navy has selected a small business in Florida called Modus Operandi to develop a new software-based intelligence system that will fuse information from a variety of sources to identify possible security threats more quickly and efficiently. This system, called the Semantic Targeting and All-source Fusion Framework, or STAFF, represents the latest in military technology.

It will combine a range of ways to gather intelligence, including human intelligence, signals, video, and moving-target indicator data. This involves using radar to find a moving target among fixed objects. STAFF will take the varied inputs it gathers and use both text analytics and semantic technologies to model and create relationships between the entities, activities and events that are identified in the intelligence. This output can then be accessed by authorized military personnel through the Navy's enterprise network to gauge possible threats.

A New Jersey man who allegedly sold sensitive US military technology to China was arrested this week by federal agents. The man, Sixing Liu, is 47-years old and was born in China, but he is now a permanent resident of the US. He has been charged with one count of exporting defense-related technical data without a license. According to the complaint, Mr. Liu who was known by the first name of "Steve" worked for a NJ based technology company over the last two years where he was a part of the senior engineering staff.

The company had a contract to work on precision navigational devices and other components for the US Department of Defense (DOD). Mr. Liu flew to China for a vacation last year, and when he returned the US Customs and Border Protection agents found that he was carrying a computer containing hundreds of documents related to his company's DOD projects. He never informed his company of the travel plans, which is a violation of their security protocol.
