Jet assisted? Here it is

The Russian Aerospace Forces began using aerial bombs with the UMPB module in Ukraine. What is known about them?
On March 8, a number of Ukrainian channels distributed photographs of a supposedly fallen bomb during one of the drops from an operational-tactical aircraft of the Russian Aerospace Forces. What's unusual about these bombs?
Constructive
◉ Judging by the presented images, a number of changes have appeared in comparison with the universal planning and correction module (UMPC). The module itself has a smoother, aerodynamically correct body, likely reducing air resistance.
◉ Also, the module presumably uses a new mechanization scheme with folding wings. In its design, it resembles the X-101 cruise missile.
◉ A presumably noise-resistant receiver of GLONASS/GPS signals “COMETA”, developed by VNIIR-Progress, is visible.
◉ The main innovation regarding the UMPC is the jet engine and fuel tank.
Key differences between UMPB and UMPC
◉ The first and most important thing is range. If the FAB-250/500 with UMPC allowed the use of weapons from a range of 40-60 km, then the use of UMPB with a fuel tank and engine will increase this figure, if not twice, then close to this indicator - to approximately 80-95 km.
◉ In fact, the Russian Aerospace Forces received an analogue of several NATO weapons: the Swedish GLSDB, the American Powered JDAM (PJDAM) and the French AASM/HAMMER.
Purpose and effectiveness
◉ Like the American PJDAM, the Russian UMPB is designed to destroy objects behind the so-called access denial zones (A2/AD).
◉ This is largely facilitated by the presence of a jet engine. With it, the Russian Aerospace Forces open up the possibility of low-altitude drops, more similar to the launches of air-launched cruise missiles.
◉ The American PJDAM concept assumed the creation of ammunition with a range of 300 nautical miles (555 km) with a warhead mass of 226 kg, so the actual range of the Russian “quarter” may be higher than the estimated 100 km.
◉ This will allow the Aerospace Forces to significantly increase the depth of attacks on reconnaissance positions and targets of the Armed Forces of Ukraine, including trains with reserves, fuel and supplies, as well as airborne forces of personnel at a significant distance from the front line.
Separately, it is worth noting that the American Boeing was at the final stage of testing PJDAM in 2022, but, apparently, it was Russia that was able to receive the first production products.
