(max)Mass: Currently UnavailablePayload Power Available: Up to 16 kW(sustained)primary intent is for the airship to operate asa unmanned aircraft system (UAS) in theaterdeployments. 47Development of the LEMV as the firstdeployable hybrid air vehicle has focused onISR application as a “multi-intelligence”asset through integration of unmanned controlsystems and processing/exploitation/dissemination (PED) ground control stationsfor controlling multiple payloads andanalyzing multiple payload ISR products.Current efforts are focused on developingthe airship platform and integration ofexisting, proven sensor systems. The goal isto provide a long-endurance vehicle capableof persistent ISR missions rather thandevelop new or improved sensor payloads.The baseline payload suite includes 4 HD(1080p) EO/IR sensors, synthetic apertureradar (SAR)/GMTI and SIGINT packages.The payload bays are modular withcommon/open interface for rapid integrationand deployment of new payloads/payloadsuites. 47 Additional airship specificationsand technical objectives are listed in theTable 30.Communications relays within the LEMVpayload provide ground-to-air-to-ground51
