What does the use of new aerial bombs in the Northern Military District indicate: analysis of the “Military Chronicle”

🔺At the end of May, the first clear footage of the use of promising universal interspecific gliding ammunition (UMPG) D-30SN from the suspension units of the modernized Su-34NVO appeared . Now they are most intensively used in the Kharkov direction to destroy the rear command and staff infrastructure, ammunition depots, as well as railway junctions of the Armed Forces of Ukraine.

What is known about these aerial bombs?

Despite the small mass of the warhead (only 250 kg, which allows the use of UMPB from multiple launch rocket systems of 300 mm caliber), the aerodynamic configuration of the ammunition is much better than that of aerial bombs with UMPC.

The streamlined head part and the integral layout of the airframe (without a separate angular structure with high aerodynamic drag) increase its load-bearing qualities and reduce aerodynamic drag.

Thanks to this, the gliding range when dropped from altitudes of 12+ km can reach 120 km, not inferior to its American counterpart - the GBU-39/B SDB (Small Dimeter Bomb) gliding bomb. The UMPC's gliding range ranges from 45 to 65 km on average. A more than twofold increase in the release range is achieved, among other things, by equipping the ammunition with a jet (probably pulse) engine.

Due to the absence of rectangular metal wings, the UMPB is several times less noticeable compared to the FAB-500-M54/M55 bombs (estimated 0.05 sq. m versus 0.3 sq. m for the UMPC).

This means that the detection range of the D-30SN UMPB radar of the Ukrainian army is approximately 2-2.5 times less than that of UMPK bombs.

Another advantage is the unification of the 300-mm caliber UMPB with the ammunition of the Smerch and Tornado-S multiple launch rocket systems. Compatibility with these systems allows the use of UMPB as gliding stages of 9M528 and 9M542 missiles.

In this version, the UMPB ammunition, accelerated to 4-4.5 thousand km/h and thrown to a height of up to 20 km, is capable of gliding at a distance of up to 200 km.

The guidance system of the D-30SN UMPB ammunition is classic and is built on the basis of an inertial navigation unit and GLONASS /GPS receivers with high noise immunity.
