620:. The Pentagon suspended trials of the system after the incident until the Army completed its investigation of how the aerostat broke free. The program was said to be "hanging by a thread" after the incident. By February 2016, the investigation had found that a malfunctioning pressure sensing device caused a loss of air pressure in the tail fins, leading to the loss of aerodynamic efficiency which, along with increased wind drag, exacerbated tension on the tether to the point of breakage. Following the incident, the military initially decided that the JLENS should continue with its operational exercise because of the unique cruise-missile defense capability it provides, determining that changes and procedures will enable it to safely fly again.

JLENS aerostats are filled with 590,000 cubic feet (17,000 cubic m) of non-flammable helium. Given its operational altitude, the internal pressure of JLENS is about the same as the exterior pressure, which makes the system difficult to shoot down. Airships can absorb multiple punctures before they
