Russia’s UMPK guidance kits fitted to the FAB series drop bombs now have a new jet-powered variant, which can reportedly extend the range up to 200 km.
Russia is now using a newer, jet-powered version of its UMPK (Universal Module for Planning and Correction/Unifitsirovannyi Modul Planirovaniya i Korrektsii) kits for the FAB series of unguided gravity bombs. He remains Almost intact examples of such a bomb, which may not have detonated, were found on October 20, 2025, in the Poltava Oblast of northeastern Ukraine, according to the deputy director of the Russia Program at the Foundation for Defense of Democracies, John Hardie.
The main Kremlin-aligned and politically tough Telegram channel ‘Fighter-Bomber’, with links to many Russian frontline units, identified the specific configuration of the glide kit as the UMPK-PD, and the bomb as the FAB-500T. Other accounts identified it as the UMPB-5R. ‘Avia Hub’Another Russian Telegram account puts the range of this particular kit with the FAB-500T at 100 km, and the range of the jet version at 200 km.

UMPK-equipped FAB-250, FAB-500, FAB-500, FAB-1500 bombs, dropped by the Su-34 Fullback fighter-bomber in battlefield interdiction roles, have been used on Ukrainian ground positions since 2023 with devastating impact.

He ISW (Institute for the Study of War), citing Russian reports, had said that the UMPK-equipped FAB-3000, FAB-250 and FAB-1500 have a range of 50-60 km to 60-70 km respectively. The UMPK-PD, like the other FAB bomb kit, is also largely crude, rudimentary and hastily improvised, possibly by technical teams from front-line units.
UMPK/UMPC Kits from Russia
These ad hoc efforts could be funded through the communities of Russian nationalist Telegram defense channels like Fighter-Bomber, Rybar, and many others. They have long crowdfunded utilities and military accessories for frontline units on the open market.
The practice has the The blessings of the Kremlin to ease the burden on the Russian defense industry and the bureaucracy of the Ministry of Defense. Since February 2022, these organizations have been dedicated to financing, coordinating and producing weapons and defense components of greater capital.
Evolution of the sliding/correction modules for FAB-500 (UMPK):
1.UMPK — ≤75 kilometers; Kometa-M4 navigation unit
2.UMPK-PD — ≤100 km; extended wings, Kometa M8 – M12
3.UMPK-PDM — ≤150 km; Redesigned module, longer wings, possible turbojet, Kometa M12.

Experience from previous kits led to the emergence of the huge FAB-3000 UMPK configured munition, which first appeared in early July 2024. A video from the Russian Ministry of Defense (RuMoD) showed it being launched by a Su-34 at a Ukrainian ground position.
As we had pointed out here in The aviationistIt is possible that the RuMoD may have gathered older clips of the bomb explosion and launch to reinforce the weapon’s effectiveness. However, the ammunition had become a headache for Ukraine’s limited Western and Soviet air defenses. President Volodymyr Zelensky periodically raise a alarm how are they in a hurry while countering Russian attacks, until new NATO deliveries arrive.
I took another closer look at the video: the first 2 seconds and last 8 seconds certainly show a UMPK-equipped FAB-3000 M-54 (see top two images). Less sure about the middle footage (see bottom two images), especially at 0:02 – 0:07; possibly FAB-1500 M-54 equipped with UMPK. https://t.co/CgmCi2X2TR pic.twitter.com/DBNNLjGlDL

The crude and improvised winged guide kits finally found more refined expression in the form of the UMPB. D-30SNwhich appeared in May 2024 launched by the Su-34. This is largely analogous to the GBU-39 SBD (small diameter bomb), which was one of the few Western and American munitions to achieve notable success against Russian targets despite intense electronic warfare and SATNAV (satellite navigation) jamming.
Interesting new photographs uploaded to a Russian TG channel showing two UMPB D-30SN munitions attached to racks under the port wing of a VKS Su-34. The still image at the bottom right, taken from a clip posted by the same channel, appears to show two of those munitions shortly after their launch. https://t.co/ohDc06Yxzb pic.twitter.com/hgJDrqFKxO

The lack of an active radio frequency or infrared signature in gliding bombs leaves little trace for radar sensors and surface-to-air missiles. While Ukraine was limited by limited Western supplies from its own arsenals, Russia had a huge arsenal of Cold War-era FAB bombs.
Last year the RuMoD also presented then-Defense Minister Sergei Shoigu visited a factory in the Nizhny Novgorod region, inspecting the “production ramp-up” of the FAB-500, FAB-1500 and FAB-3000 bombs.
Evolution of the UMPK and UMPK-PD kits
The first UMPK kit, especially the FAB-500T, had deployable wings on a fairing that hugged the bomb body with semicircular straps on both sides that joined at one point and were fastened with clasps. The second UMPK kit had the same design, except that the fairing extended to the tail of the bomb.
This kit, which was observed both in August 2024 and September 2025Sources said it increased the range of the FAB-500 from 60 to 70 km to 80 to 90 km, when dropped from an altitude of 10,000 meters.
A longer fairing may have been introduced to improve aerodynamic performance, better lift or stability. The nose section of both kits, believed to house the guidance electronics, however, diverged from the nose and protruded prominently.
However, the fairing of the new FAB-500T UMPK-PD has a shorter front section, the flat base of which sits perfectly on the surface of the bomb. The other half is curved, with the slope almost in the same line as the pump, forming a very small angle.
The claimed turbojet section is the tubular end of the pump which replaces the standard conical end. TO up close engine revealed that it was a commercially available SW800Pro-Y manufactured by Chinese company Swiwin.

All three types of bombs rotate 180 degrees after being dropped, with the strapped fairing holding the wings on top. The new design appears to be made of lighter material and possibly smaller, more efficient electronics.
Another technical evolution in the guidance section of the bomb was observed by OSINT and the drone warfare analysis account. ‘Roy’ in April. He noted that the UMPK glide bombs use 12-antenna CRPA SATNAV modules instead of the original eight-antenna configuration. This made them more resistant to SATNAV (GPS and GLONASS constellations) interference by Ukraine.
