In the current context of naval force development, improving the effectiveness of aerial surveillance and target acquisition systems has become a pressing priority. In the Russian Federation, specialists at the Moscow Aviation Institute have developed a conceptual design for a carrier-based long-range radar detection aircraft featuring a fundamentally new radar system architecture. The documentation for this technical solution has been registered in the database of the Federal Institute of Industrial Property, indicating that the preliminary design phase has been completed.
Design Features of the Radar System
Traditional designs for AEW aircraft, including domestic models such as the A-50 and the future A-100 “Premier,” involve mounting a rotating antenna system in a fairing above the fuselage. The proposed design departs from this configuration in favor of integrating an active phased-array antenna directly into the airframe’s structural elements. The aircraft’s fuselage is disc-shaped, which ensures uniform distribution of the electromagnetic field in near-Earth space and minimizes signal shadowing caused by structural elements.
Integrating the radar system into the airframe significantly expands the field of view in the lower hemisphere, which is critical for detecting low-flying targets against the backdrop of the sea surface. The absence of external protruding elements reduces aerodynamic drag and improves the aircraft’s maneuverability while maintaining the specified radar field parameters.
Aerodynamic Configuration and Performance Characteristics
The aircraft under development is designed to operate from aircraft-carrying ships. To this end, the wing assembly is equipped with a folding mechanism that allows for compact storage within the limited space of ship hangars. The power plant and the flight and navigation system are housed in a superstructure above the fuselage that smoothly transitions into the tail boom, which optimizes the center of gravity and improves stability during takeoff and landing.
The watertight design of the disc housing enables emergency landing on water, which enhances crew safety when carrying out missions in the world’s oceans. This feature represents a significant advantage over traditional designs that lack buoyancy.
Theoretical Justification for the Effectiveness of an Integrated Antenna System
From the perspective of radio engineering analysis, positioning the phased array antenna in the plane of the disk ensures the formation of a continuous radar field without the sectoral gaps characteristic of mechanically rotating systems. The uniformity of the radiation pattern helps increase the probability of detecting small targets and reduce the response time of the target-acquisition system. The absence of mechanical antenna rotation drives potentially increases the system’s reliability and reduces maintenance costs.
The Context of Development Within the AEW&C Systems Modernization Program
The development of an alternative concept for an AEW&C aircraft is taking place amid a reevaluation of approaches to the creation of specialized aviation systems. According to open-source information, reports emerged in December 2025 that the A-100 “Premier” aircraft program had been suspended, which has reignited the search for innovative technical solutions in this field. The design proposed by the Moscow Aviation Institute can be viewed as a promising alternative that combines elements of miniaturization, systems integration, and improved tactical and technical performance.
Conclusion
The presented conceptual design of a long-range radar detection aircraft with a disc-shaped fuselage and an integrated antenna system demonstrates potential advantages in terms of radar coverage, aerodynamic efficiency, and operational flexibility. Further research should focus on experimentally verifying the calculated performance characteristics, assessing the electromagnetic compatibility of onboard systems, and analyzing the economic feasibility of implementing this technical solution within the framework of the state armaments program.
