While the ST Aero MAV-1 is a low observable Unmanned Air Vehicle prototype developed between ST Aerospace and Defence Science and Technology Agency, what is designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio-frequency (RF) spectrum, and audio?
ST Aero MAV-1 The MAV-1 (Maneuvering Air Vehicle) is a low observable Unmanned Air Vehicle prototype developed between ST Aerospace and Defence Science and Technology Agency for its swarming unmanned air vehicle research programme. The prototype was unveiled in Asian Aerospace 2004 and the first test flight was reported in 2005.
JLENS The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System, or JLENS (colloquially, Spy Balloon), is 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 has four primary components: two tethered aerostats which utilize 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 is referred to as an "orbit", and two orbits have been built. The Army-led joint program is 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. The program was suspended in October 2015.
