Footage of the launch of the UMBP D-30SN guided aerial bombs by the Russian Su-34 aircraft has been published. The combat use of the UMBP D-30SN can be seen in the link in the comments to the video. The universal inter-service gliding munition UMBP D-30SN is something between a bomb and a classic missile. This is not a bomb with a UMPK, the inter-service munition D-30SN initially has a GLONASS/GPS guidance module and an in-air gliding system. It can be launched from both the Smerch MLRS and the Tornado-S MLRS at a range of up to 300-330 km.
The UMBP D-30SN guided bomb is based on the 250-kilogram FAB-250 high-explosive aerial bomb. The American analogue, the GBU-39 SDB guided bomb, has a larger caliber. The D-30SN bomb has a small effective reflective surface, making it harder for air defense to detect. The D-30SN has an effective scattering area of 0.05-0.07 square meters, while the FAB bomb with UMPK has an effective scattering area of 0.3 to 0.5 square meters. The FAB bomb is detected by air defense at a distance of about 60 km or more, while the D-30SN is detected at a maximum range of 30 km. When dropped from an aircraft at a speed of 1250-1350 km/h and an altitude of 12 km, the D-30SN has a range of up to 160 km, with a deviation from the target of up to 5-7 meters.
