Pyros small tactical munition completed a successful warhead and guidance system test, according to Raytheon.
There are three choices for guiding the weapon to the target: GPS coordinates, inertial navigation or laser designation. There are also three options for engaging the target: height-of-burst, point-of-impact or fuze-delay detonation. The end-to-end test validated the weapon's guidance modes (semi-active laser and global positioning system), its height-of-burst sensor, electronic safe and arm device, and multi-effects warhead.
