In the 1980s, Northrop built a next-generation target, the NV-144, that was substantially bigger and faster than the Chukar III, but the NV-144 did not enter production. The latest and current effort by Northrop Grumman to improve the Chukar is the BQM-74F variant of the Chukar (previously called the Target 2000).
Short baseline systems get their name from the fact that the spacing of the baseline transducers (on a boat for example) is usually much less than the distance to the target, such as a robotic vehicle or diver venturing far from the boat [3] As with any acoustic positioning system, a larger baseline yields better positioning accuracy.
It was intended to make a one-way trip, eject its camera payload at the end of the mission for recovery, then self-destruct. [2] It had a double- delta wing similar to the A-12's wing design. The Q-12 was to be air-launched from the back of an A-12, and used key technology from the A-12 project, including titanium construction and radar cross ...
A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker that produces sound at high power for communicating at a distance. It has been used as a method of crowd control , which has caused permanent hearing damage , having an extremely high decibel capacity (up to 160 dB measured at one ...
Ingenuity, nicknamed Ginny, is an autonomous NASA helicopter that operated on Mars from 2021 to 2024 as part of the Mars 2020 mission. Ingenuity made its first flight on 19 April 2021, demonstrating that flight is possible in the extremely thin atmosphere of Mars, and becoming the first aircraft to conduct a powered and controlled extra-terrestrial flight.
A XQ-58 Valkyrie deploys an Altius-600 unmanned aircraft system. The XQ-58 Valkyrie fell within the USAF Research Laboratory's Low Cost Attritable Aircraft Technology (LCAAT) portfolio, whose objectives included designing and building unmanned combat aerial vehicles (UCAVs) faster, by developing better design tools and maturing and using commercial manufacturing processes to reduce production ...

The FireFly Acoustic Threat Detection System is a system for detecting hostile fire. It has been developed jointly by the US Army Aviation and Missile Research Development and Engineering Command (AMRDEC), the U.S. Army Research Laboratory (ARL) and industry partners. The FireFly acoustic and electro-optical (EO) sensor can operate with ...
