The Buk-MB3K is a recent Belarusian air defense ᴍɪssɪʟᴇ system. It is an extensively upgraded version of the Soviet Buk.

In 2005 an upgraded Buk-MB was publicly revealed in Belarus. A further upgraded Buk-MB2 was publicly revealed in 2019. The Buk-MB3K is its further evolution. Letter “K” in the designation denotes that it uses a wheeled chassis.

The Buk-MB3K is based on a Belarusian MZKT-692250 special wheeled chassis with 8×8 configuration. This air defense system uses a Ukrainian radar. This new Belarusian system can engage aircraft, helicopters, ʙᴀʟʟιsтιc мιssιʟᴇs, cruise мιssιʟᴇs, anti-radiation мιssιʟᴇs.

The Transporter Erector ʟᴀuɴcнᴇʀ and Radar (TELAR) vehicle is referred as the 9A318K. It is fitted with a radar and carries 4 мιssιʟᴇs. It is compatible with older Buk мιssιʟᴇs and can also used newly-developed Belarusian мιssιʟᴇs. It can fire the 9M38, 9M38M1, 9M317, 9M38MB, 9M38MB1 and 9M318 surface-to-air мιssιʟᴇs.

Buk-MB3K air-defence review:

The 9M38M1 is an improved мιssιʟᴇ with semi-active guidance. It was originally introduced together with the Soviet Buk-M1 air defense system back in 1983-1984. The мιssιʟᴇ weights 690 kg.

The 9M38MB is a Belarusian upgraded version of the 9M38 мιssιʟᴇs. Belarus has some stocks of the old 9M38 мιssιʟᴇs that are reaching the end of their storage lives. Some of these мιssιʟᴇs are being upgraded to new standards by replacing their seekers and sensors, onboard electronics, engines and other components. The upgraded 9M38MB мιssιʟᴇ has a range of 32 km and can reach targets at an altitude of 18 km. The мιssιʟᴇ weights 680 kg and carries a 70 kg wᴀʀнᴇᴀᴅ.

Radar of the TELAR can detect ғιԍнтᴇʀ-size aircraft, such as a MiG-29, at a maximum range of up to 130 km. There is also an electro-optical thermal imaging guidance channel. It is effective out to a range of 40 km. The system can engage 6 targets simultaneously. It takes 5 minutes from traveling to prepare the TELAR vehicle for ғιʀιɴԍ. The TELAR vehicle is operated by a crew of 3.
