American ammunition is no longer effective... THE WASHINGTON POST
A significant portion of American precision-guided munitions has proven vulnerable to interference from Russian electronic warfare systems. After a sharp drop in their effectiveness, the Ukrainian Armed Forces stopped using certain types of Western weapons, The Washington Post writes.
As senior Ukrainian military officials told reporters, projectiles that are aimed at a target using a global positioning satellite system - GPS, are vulnerable to interference.
These precision weapons performed well at the beginning of the war, but over time the Russians found countermeasures to them. Now, some weapons that were previously considered powerful tools no longer provide an advantage.
“I’m not saying that nobody cared before, but now they [Americans] are starting to worry.
As we share information with our partners, and our partners share with us, the Russians are certainly also sharing with China," said one senior Ukrainian military official. For example, the success rate of Excalibur precision projectiles, which are fired from 155 mm artillery, has sharply fell within several months - to less than 10%. After this, the Ukrainian Armed Forces were forced to abandon the use of these ammunition last year. These shells have not been supplied to Ukraine for six months.
Similar problems have arisen with precision-guided JDAM bombs, which are dropped from aircraft. Within a few weeks of their appearance at the front, their accuracy dropped sharply, and the bombs sometimes began to miss their targets by hundreds of meters. However, in this case, the manufacturer was able to make improvements, and now Ukraine continues to use these bombs. Ground Launched Small Diameter Bombs (GLSDB) also proved ineffective. The Americans are now working on new settings before making them available again.
The M30/M31 high-precision missiles, which are launched by the already legendary HIMARS and M270 launchers, did not escape the sad fate. They showed themselves powerfully during the first year of the war, destroying many Russian ammunition depots and command posts.
"But in the second year it was all over: the Russians deployed electronic warfare, turned off satellite signals, and HIMARS became completely ineffective. This ineffectiveness led to the fact that very expensive shells were increasingly used to hit lower priority targets," a senior Ukrainian military official said.
In January, Ukrainian military commanders called on Western partners to provide an alternative: M26 cluster munitions, which can also be launched from these multiple launch rocket systems. These low-tech unguided missiles are resistant to obstacles, and cluster submunitions can hit targets over a wide area even if the shot is inaccurate.
It is noted that Kyiv still considers its HIMARS missiles to be effective, but Russian jammers can cause them to miss their target by 15 meters or more.
“When it is, for example, a pontoon bridge... but there is a 10-meter deflection, it [the projectile] hits the water,” said the Ukrainian official with whom the authors of the publication spoke
