Nearly since its inception ACUASI has flown InSitu ScanEagle UAS's but over the years we've preferred to convert them to the more capable Nanook system. Out of all of the UAS that ACUASI uses, the ScanEagle is one of the longest running platforms and accordingly is the one with which ACUASI has the most experience, especially in challenging environments. The ScanEagle is a capable platform, with a zero-length catapult launch and snag line recovery system and a payload of ~3 kg, loaded weight <50 lb, 1 kW power, 60-80 kts cruise/dash range, and endurance of up to 24 hours, depending upon configuration and flight conditions.
