Attack Aircraft II

A new medium size/medium range supersonic stealth fighter bomber concept (JH-21? Project 176?) was studied at the 601 Institute in the 2000s. It appeared to feature a twin seat cockpit and twin engines. A mock-up (head section?) was constructed at SAC during 2013. The design was rumored to have been transferred to 603/XAC to be further developed into a medium stealth bomber. The current status of this project is unknown.

H-20

A new long-range strategic bomber design (H-20?) has been under development at 603 Institute/XAC since early 2000s. Various configurations were studied in detail. One configuration was a supersonic bomber with a conventional design (delta wings with canards?), another was a 4-engine subsonic stealth flying wing design similar to American B-2. Scale-down models were built. By 2011 the overall configuration was finalized which appeared to be a flying wing design. However in early 2021 a flying wing with movable stabilizing tail fin design was speculated but remained unconfirmed. Some of the technology including the design of flying wing, dorsal engine intake and exhaust as well as the flight control system might have gained some help from the experience of the Sharp Sword UCAV. The engine is likely to be either the modified WS-10 without A/B or D-30KP-2 without reverse thrust. The aircraft is expected to feature an AESA radar with twin conformal antennas below the leading wing edges similar to American AN/APQ-181 LPI radar. For armaments it can carry KD-20/DF-10K ALCMs internally on a rotary launcher or conventional bombs on bomb racks. H-20 is believed to be able to evade modern air defence systems and penetrate deep into the enemy territory. Estimated weapons payload 17t, combat radius 4,500km. It was reported in March 2013 that the development of H-20 (referred to as the "strategic project") is gaining full speed at 603/XAC after the successful flight of Y-20. It was reported in November 2015 that the aircraft could feature twin dorsal S-shaped engine intakes with saw tooth lips similar to those of B-2. Consequently the engines are sunk into the main wing structure to further reduce the RCS. It was reported in December 2015 that a 3D digital prototype was built. It was reported in February 2017 that the QC platform of the digital prototype was built. Recent news (July 2018) indicated that the tail section of the S-shaped exhaust pipe has been manufactured. It was reported in September 2018 that an Iron Bird test platform was built. The flying wing design of H-20 was partially unveiled to the public in an XAC promotional video in May 2018, which suggests a configuration bearing more resemblance to American B-21 than B-2. A recent news (October 2020) suggested that the test of its flight control system was completed. The latest satellite image (October 2020) suggested an RCS measurement model has been built. First flight is currently speculated to be 2023. The latest news (July 2021) suggested that a full-scale mock up has been built.
