Russia's internal problems
On the front line, it is suspected that the Excalibur GPS guided bomb is detonated with a close-fire fuse at a height of the best kill range above the ground.
The UAV observes and determines the latitude and longitude of the target, and enters excalibur's inertial navigation system to shoot. Excalibur will refer to GPS signals and positioning in the air to calculate the geographical location of the landing point. If there is an error with the target position, it will drive the control surface on the projectile to correct the channel ...
The 1L260 radar can track the shells fired in the air and calculate the position of the starting gun from the ballistic trajectory. This information was passed to his artillery command post to command the anti-artillery bombardment. Hitting the artillery radar significantly reduces the threat of a quick counterattack from friendly artillery fire.
The killing mechanism of the bombardment radar and support and command vehicles is "fragmentation"... Artillery shells can be covered by aerial explosions and dispersed fragments, and the killing and injury are large. Fragments can destroy radar equipment, penetrate command vehicles to kill people, and destroy equipment inside.
The knock force of the PBXN-9 charge inside the Excalibur shell is tuned to produce fragments of the appropriate size.
During World War II, it was found that when RDX explosives with a larger knocking force than TNT were used as artillery shells, the fragmentation lethality was not significantly improved. The reason is that the detonation force is too large, and the projectile body is blown into too small fragments. Later, the proportion of RDX in the charge was adjusted to reach a moderate average fragment size ... It can kill or injure people or penetrate bunkers, fortifications or light armor of vehicles.
When playing radar, there is no need to crush the integrated structure, and after the broken piece of the connecting antenna is broken, it cannot be used ...
