became convinced that the Global Hawk derivatives would be unable to meet the safety standards needed for flying through European airspace by 2025 and saw their hopes dashed as Italy recently issued a military-type certificate for a sister drone — NATO's Alliance Ground Surveillance fleet of Global Hawks — that prescribes tight restrictions on flights over the European continent. Manned aircraft like the envisioned Global 6000 are allowed to routinely fly alongside civilian traffic. Design The MQ-4C can remain aloft more than 30 hours at at speeds of up to . Its surveillance sensor is the AN/ZPY-3 Multi-Function Active Sensor (MFAS) X-band AESA radar with a 360-degree field-of-regard, capable of surveying of sea (as well as shoreline or land) in a 24-hour period, or in a single sweep. Using the radar in inverse synthetic aperture mode, the MFAS can identify a target in all weather conditions. It can take high definition radar pictures, then use the advanced image and radar return recognition software of the onboard Automatic Identification System (AIS) to classify it without the intervention of aircraft operators. The Triton is semi-autonomous to conserve manpower, so operators only need to choose an operating area for the aircraft, and set speed, altitude, and objective rather than operating controls. One thing the Triton was designed to do (that the Global Hawk cannot) is rapidly descend to lower altitudes. It is built with a more robust lower fuselage to withstand hail, bird, and lightning strikes. It is equipped with anti-icing systems on its wings. At low altitude, the Triton would use its Raytheon MTS-B multi-spectral EO/IR sensor (also used on the MQ-9 Reaper) which is equipped with additional laser designator, pointer, and range finding abilities capable of automatically tracking what the MFAS detects. The optical suite can stream live video to ground forces. The Triton is equipped with a modular electronic support measures (ESM) suite, similar to the one used on the Lockheed EP-3, to passively detect and classify faint radar signals. It is able to triangulate and geo-locate these signals, allowing mission planners to create an enemy "electronic order of battle" profile, or keep the aircraft and others outside the range of enemy radars and air defenses. Detecting and locating the source of radar signals would also be useful for locating military vessels at sea for potential targeting. Low- and high-band signals receivers to give it a multi-INT (SIGINT) capability will
