The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System , or JLENS (colloquially, Spy Balloon ), was a tethered aerial detection system designed to track boats, ground vehicles , cruise missiles , manned and unmanned aircraft ( airborne early warning and control ), and other threats. The system had four primary components: two tethered aerostats which utilized a helium/air mix, armored mooring stations, sophisticated radars, and a processing station designed to communicate with anti-missile and other ground and airborne systems. Each system was referred to as an "orbit", and two orbits were built. The Army -led joint program which fielded JLENS was designed to complement fixed-wing surveillance aircraft , saving money on crew, fuel, maintenance and other costs, and give military commanders advance warning to make decisions and provide notifications. Following cost overruns, underperformance, declining support in Congress, and public scrutiny following a snapped tether which allowed one craft moored at Aberdeen Proving Ground , Maryland to drift on a 100-mile uncontrolled descent across Pennsylvania, dragging its cable tether which damaged power lines and cut power to 20,000 homes, the program was suspended in October 2015, and completely discontinued by 2017.

765-505: A report by the Government Accountability Office concluded that $ 2.78 billion had been invested in system design, development and other costs. Following incidents with the JLENS aerostats, some retired military officials suggested that the system's sophisticated sensors be moved to more reliable platforms like satellites or long-endurance UAVs to fulfill the role of detecting low-flying cruise missiles. Since

850-1052: A statement denying the closure. When the schools opened on September 9, Wallace was served a restraining order against further interference with the desegregation of Huntsville schools. Huntsville became the first city in Alabama to desegregate its schools as well. Alabama's opposition to desegregation at this time caused concern from the NASA Administrator James E. Webb , who investigated equal employment opportunities for Black people in Huntsville. After failing to attract high-level staff to Huntsville, Webb said that "some research work would have to be switched from Huntsville to New Orleans". This investigation into employment caused MSFC to open their engineering education programs to Black students at Alabama A&M and Oakwood College , as well as for local contractors to "work for progress in race relations". The emergence of

In the fall of 2010, a JLENS prototype was destroyed when another airship crashed into it after becoming unmoored during severe weather. On October 28, 2015, one of two JLENS aerostats being used to conduct a test over Aberdeen Proving Ground in Aberdeen, Maryland , became untethered. It was escorted by two fighter jets as it drifted at an altitude of approximately 16,000 feet (4,900 m) towards Pennsylvania. About three hours later, it

5780-431: The targeting radar looks only in a certain segment to guide weapons to it. Its detection capability seeks to equal 4–5 fixed-wing aircraft, and is designed to operate at 15–20 percent of the cost of fixed-wing aircraft. The tethered cables relay data and provide power. As threats are detected, information is sent to anti-missile and other fire-control systems including Patriot , Standard Missile 6 , AIM-120 AMRAAM , and

The deployment joined an ongoing exercise known as Operation Noble Eagle , with JLENS casting an aerial net from Boston to Lake Erie to Raleigh, North Carolina , with

6035-502: The two test model systems were put into operational service. Privacy advocates raised concerns that the deployment could be used to track individuals by generating radar geo-location data and correlating it with other technology, including cellphone metadata and traffic cameras.
