[2] The A-100 is also known as the Izdeliye PM, and is planned to reinforce and then replace Russia's current fleet of Beriev A-50 AEW&C aircraft.

The external shape of the A-100 will be similar to the A-50, with the main radar array housed in a rotating dome mounted on two struts above the fuselage.

The array will rotate once every 5 seconds, thus improving the radar's ability to track fast moving targets.

[5] A flying laboratory, designated A-100LL and based on an A-50 airframe, is used to test the operation of the A-100's systems and help with their conception.

[3] In April 2020, it was said by a source in the Russian military industry that Russia's Aerospace Forces will begin taking delivery of the new Beriev A-100 in 2024, to complement and eventually replace the existing Beriev A-50 and A-50U AEW planes in the Aerospace Forces’ inventory.
