A CLOSER LOOK AT CHINA'S DIVINE EAGLE DRONE | Popular Science "The Divine Eagle is a low observable, high altitude UAV meant [to] detect stealth aircraft at long ranges, using special purpose radars." "Formations of Divine Eagle UAVs are expected to provide an early warning line to detect threats to China's airspace, like cruise missiles and stealth bombers, as well as be able to take on such missions as hunting for aircraft carriers in the open waters of the Pacific." "The double bodied layout was chosen in order to provide the surface area for carrying large radars, while minimizing internal volume and weight." "This CGI offers a view of the differing yellow, green and grey blue primer coatings on the Divine Eagle suggest the usage of different materials like composite and aluminum alloys for different sections of the UAV. For example, the grey blue forward dome on the port (left) body is likely to contain a satellite dish for long distance communications, while the grey blue sections on the twin bodied fuselage likely house radar arrays." "[The] yellow, green and grey blue primer coatings on the Divine Eagle suggest the usage of different materials like composite and aluminum alloys for different sections of the UAV. For example, the grey blue forward dome on the port (left) body is likely to contain a satellite dish for long distance communications, suggesting that the material used in the grey blue sections are likely to be highly permeable to electromagnetic waves. The grey blue is also to be found on the starboard side of the right body (facing outside), and if the airframe composition is symmetrical, likely to be found on the portside of the left body (also facing out). Such electromagnetic permeables are likely to house the Divine Eagle's long range anti-stealth radars (radomes are made of radar transparent materials), indicating that its radar arrays are 10 meters long, which suggests transmitting lower frequency (L and S Band) radar waves (most stealth aircraft are optimized to evade higher frequency, such as X band, radar). The green primer likely covers lightweight materials such as composite, while the yellow primer near the engine suggests some stronger metal alloy, probably to support the engine weight and height."
