Two news in the last hours reflect to what extent the war in Ukraine is a nonsense. On the one hand, the United States has confirmed that he is arguing with Putin LAs lands and energy plants that would find the long -awaited fire. On the other, a package is directed from Washington to Ukraine. Inside, some bombs They promise to change the current Russian advantage in the invasion.
The “offensive triangle”. They counted several analysts over the weekend that as the war in Ukraine enters its fourth year, Russia has perfected a strategy that, although it has not achieved decisive advances on the battlefield, is Erosioning systematically the abilities and moral of the Ukrainian forces. The approach, called by British experts such as the “offensive triangle,” combines infantry, attack drones and planning pumps to subdue Ukrainian forces at constant pressure.
Tactics has been particularly effective due to Current situation of Ukrainewhich faces the reduction of western military supplies, exacerbated by the decision of the Trump administration of freeze shipments of arms and all cooperation in intelligence (now reactivated both). Although Russia still does not achieve significant strategic advances, its approach is achieving an accumulation of small victories at a high human and material cost.
The key role of UMPK. One of the most novel and effective elements of this strategy has been the intensive use of UMPK planning pumpswhich have allowed Russia revive your air capacity without exposing your enemy fire planes. These bombs, which transform conventional ammunition into low -cost precision weapons, have been a key factor for Russia since Your introduction in 2023.
Unlike western systems such as The JDAM from the United States (used for more than 25 years), Russian UMPK prioritize quantity over precision. Although its accuracy is less than that of its western counterparts, its explosive power is devastating. Plus: These ammunition have proven to be particularly effective against Ukrainian trenches and bunkers, since even a close impact can destroy well prepared fortifications. It is estimated that Russia will increase its production of 40,000 UMPK bombs in 2024 70,000 in 2025which will mean an even greater challenge for Ukraine.
American aid: GLSDB. The response of Ukraine to the Russian offensive triangle will arrive thanks to the reactivation of military aid and intelligence cooperation in the United States. To be more exact, a New improved version of the GROUND-LAUNCHED SMALL DIAMETER BOM (GLSDB).
The bomb, which debuted on the Ukrainian battlefield months ago, had a disappointing performance, especially due to the advanced electronic warfare capabilities of Russia, which led to its use was suspended. However, with the growing need for long -range armament after the decrease in reserves of Atacms missilesGLSDB has been reevaluated and modified to counteract electronic interference and improve its effectiveness.
The modifications. According to Reutersthe new versions of the GLSDB include structural reinforcements to better withstand launch tensions, in addition to an optimization in Your GPS navigation systemwhich would do it more resistant to blocking and supplantation of signals (Jamming/Spoofing). In fact, to validate these improvements, 19 launch tests were carried out recently.
We remember that the bomb was developed by Boeing and Saab, a precision weapon released from the ground with remote attack capacity. Its design is based on the combination of two existing components. On the one hand, the small diameter pump GBU-39/B (SDB), used in air attacks. On the other, the M26 rocket engine, which is used in multiple launcher systems m270 mlrs and M142 Himars.
How it works. The system allows the GLSDB to be triggered as if it were a rocket to use and, after reaching a certain altitude, displays retractable wings that allow it to plan without propulsion to its target, using its inertial navigation system and GPS. Its scope is approximately 150 kmwhich makes it especially useful for Ukraine in its attempt to attack Russian infrastructure and supply lines at a great distance.
The initial problem. Although Saab had ensured that GLSDB had high precision (with a margin of error of only one meter), reports from the front suggest that their vulnerability to the Russian electronic warfare It was greater than expected. Russia has demonstrated an effective capacity to Block GPS signalswhich affected the precision of the GLSDB and reduced its effectiveness.
Interestingly, the aerial version of the SDB has worked well in the Ukrainian Air Force, which has raised doubts about why the land version suffered interference problems. It is suggested that the greatest flight distance in GLSDB may have amplified the impact of GPS signal loss.
Strategic importance and versatility. Be that as it may be despite its initial problems, GLSDB is still A key piece In the Ukrainian military strategy. Its great reach places the pump above the 227 mm rockets used in the MLRS and Himars, which allows deep attacks without the need for expensive tactical ballistic missiles such as the same Atacms. In addition, it has the advantage of being compatible with multiple launch platforms, including the MLRS M270 and the Himars M142which facilitates its integration into the Ukrainian Arsenal.
Plus: Another important factor is the availability of components, since both M26 engines and GBU-39/B pumps have broad “stock” in the US and other allies, which makes the GLSDB pump a viable and scalable option to maintain the pressure on Russia and cope with that moscow wear war with Your offensive triangle.
