Taliban seize airship and threaten world Last week the Taliban Interior Ministry in Kabul announced that they had arrested a man in Afghanistan who was in the process of selling something called the Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System (JLENS) to Iran. Apparently, the Taliban wanted the JLENS for themselves so they seized the system and locked up the seller (https://bit.ly/3MCtobw). JLENS is an aerostat carrying a very sophisticated radar system. It is used to detect missiles, drones, aircraft, boats, and ground vehicles. The JLENS surveillance radar scans in all directions and can provide constant, 360-degree coverage extending over 300 miles. During tests conducted by its manufacturer, Raytheon, the JLENS MTS-B electro-optical/infrared (EO/IR) sensor tracked numerous targets with its infrared (IR) sensor. Video from the MTS-B was passed through the aerostat's tether, enabling operators to watch a live feed of trucks, trains, and cars from dozens of miles away. While the MTS-B visually tracked targets, the JLENS simultaneously tracked the surface targets with its integrated radar system. There has been some controversy in recent years about the long-term utility of JLENS following an incident in which one of the aerostats broke loose from its tether and drifted from Maryland into Pennsylvania. Nonetheless, there has been general consensus that the radar system and other sensors are extremely capable and should be retained. In particular, the capacity of the systems to detect incoming cruise missiles, flying at low altitudes is exceptional. Each JLENS aerostat costs almost $200 million. The program overall costs billions. We developed the JLENS because the United States did not have a reliable capability to detect low flying threats like cruise missiles. Our other systems were not sufficiently advanced or capable. What the systems on the aerostat in the JLENS program gave us were capabilities no one else on the planet possessed. We have largely backed away from the idea of using large numbers of JLENS aerostats, because of the issues associated with having the vehicles tethered and keeping them from getting away. All of the systems carried by the aerostats remain in use on other aircraft however and represent some of the most advanced technology we have. That technology is now in the possession of the Taliban. Precisely why the Taliban intervened to stop the pending sale of JLENS to the Iranians remains unclear. Presumably, they either want the system for themselves or they intend to sell it to the highest bidder and pocket the cash. What is clear though is that we will exercise no control of any kind over what happens. The system may be used by the Taliban to detect future “over the horizon” attacks by the U.S. military. It may be sold to Communist China, reverse engineered, and mass-produced.
