The Russian Defense Ministry has published a promo for the upgraded A-50U airborne early warning and control aircraft. The A-50U aircraft was developed in 2011 on the basis of the A-50 aircraft. Most of the destroyed Ukrainian fighters were found using A-50U aircraft. The A-50U aircraft differs from previous modifications by a new radio-technical complex with improved parameters. The aircraft has an airborne defense complex, which includes active and passive radio countermeasures, as well as infrared jamming systems. The aircraft had a reduced mass of equipment, due to this, the fuel supply was increased. The price of the aircraft is 330 million dollars. Russia currently has 7 aircraft in service.
