A-50U可以部署在一系列任务中，包括探测、跟踪和敌我识别（IFF）确定空中和陆基目标。它还为自动控制系统的指挥所提供监视、指挥、控制和通信。

 

The aircraft can also be used to guide fighters towards their targets and conduct counter-attacks on hostile forces.

该飞机还可用于引导战斗机接近其目标，并对敌对部队进行反击。

 

A-50U upgrade programme details and technical specifications

A-50U升级计划细节和技术规范

 

The A-50U upgrade programme was announced in 1995 and the first airframe entered the test phase in 2008. The upgrade works of the aircraft are being carried out at Beriev Aircraft’s facility in Taganrog in the Rostov Region, Russia.

A-50U升级计划于1995年宣布，第一架机体于2008年进入测试阶段。该飞机的升级工程正在俄罗斯罗斯托夫地区塔甘罗格的别里耶夫航空制造公司进行。

 

The Russian Air Force received the first A-50U aircraft in October 2011, while the second and third aircraft were delivered by March 2014. The fourth aircraft was handed over to the Russian Ministry of Defence in March this year.

俄罗斯空军在2011年10月收到了第一架A-50U飞机，而第二架和第三架飞机在2014年3月交付。第四架飞机于今年3月被移交给了俄罗斯国防部。

 

The upgrade of onboard AEW&C systems significantly reduced the overall weight of the mission complex, enabling the aircraft to carry additional fuel for increased range. The landing and take-off performance, as well as stability and control of the platform remain unaltered.

机载AEW&C系统的升级显著降低了任务复合体的整体重量，使飞机能够携带额外的燃料以增加航程。着陆和起飞性能以及平台的稳定性和控制保持不变。

 

The flight and navigation suite aboard the aircraft integrates satellite navigation system for high-navigational accuracy during operations. Additionally, the new aircraft offers high comfort for occupants as it also incorporates rest rooms and a snack bar with household equipment. The aircraft is manned by a flight crew of five and ten AEW&C system operators and specialists.

飞机上的飞行和导航套件集成了卫星导航系统，可在操作过程中实现高导航精度。此外，新飞机还包括休息室和带家用设备的小吃店，为乘客提供了很高的舒适度。该飞机由五名和十名AEW&C系统操作员和专家组成的飞行机组人员驾驶。

 

The A-50U AEW&C aircraft has a length of 46.5m, wing span of 50.5m, height of 14.7m and wing area of 300m².

A-50U AEW&C飞机长46.5米，翼展50.5米，高14.7米，机翼面积300平方米。

The A-50U is equipped with the Shmel II radio technical complex (RTC), which offers advanced capabilities for detecting low-contrast land-based targets. The complex offers a radio range of 2,000km in high-frequency (HF) band and 400km in ultra-high frequency (UHF) band. The Shmel II system can track 300 targets at a time and direct interceptors against 40 targets.

A-50U装备了Shmel II无线电技术综合体（RTC），它提供了探测低对比度陆基目标的先进能力。该综合体提供了2000公里的高频（HF）波段和400公里的超高频（UHF）波段的无线电范围。Shmel II系统可以一次跟踪300个目标，并直接拦截40个目标。

 

“The A-50U can be deployed in a range of missions, including detection, tracking and identification friend or foe (IFF) determination of aerial and land-based targets.”

“A-50U可以部署在一系列任务中，包括探测、跟踪和敌我识别（IFF）确定空中和陆基目标。”

 

The upgraded RTC includes a radar system, digital computer complex, IFF, command, control and guidance system, and radio communication systems. It uses new computational tools and improved algorithms for the operation of the complex. The introduction of digital signal processing further reduces the weight and size characteristics of the RTC hardware.

升级后的无线电技术综合体（RTC）包括雷达系统、数字计算机综合体、敌我识别、指挥、控制和制导系统以及无线电通信系统。它使用了新的计算工具和改进的算法来进行复杂的运算。数字信号处理的引入进一步降低了RTC硬件的重量和尺寸特性。

 

The advanced radio systems aboard the aircraft use modern methods of installation and assembly for reduced power consumption, size and weight of the equipment, as well as increased reliability.

飞机上的先进的无线电系统使用现代化的安装和组装方法，以降低功耗、设备的尺寸和重量，并提高可靠性。

 

The operator consoles of the new aircraft also feature large, high-resolution liquid crystal displays (LCDs) replacing the cathode ray tube (CRT) displays aboard the A-50 AEW&C aircraft.

新飞机的操作控制台还配备了大型、高分辨率液晶显示器（lcd），取代了A-50 AEW&C飞机上的阴极射线管（CRT）显示器。

 

Electronic countermeasures

电子对策

 

The A-50U also features a self-defence system containing active and passive electronic countermeasures and radar reflectors. The self-defence system protects the aircraft from incoming guided and unguided missiles.

A-50U还具有一个自卫系统，包含主动和被动电子对抗和雷达反射器。自卫系统保护飞机免受制导导弹和非制导导弹的攻击。
