Egypt showed two types of ammunition that it announced were produced locally, and because we know very well that the Egyptians do not spend large sums on scientific research, as they consider scientific research a crime, so where did they get the technology from? We explain it simply.
The Egyptian ammunition that ROBOTIC ENGINEERING SYSTEM displayed, such as 155 LR GPK. The idea is based on integrating several components from different products to provide a new product without spending money on global research to produce a new, integrated product from start to finish.
Therefore, the 155 LR GPK missile is considered.
Where did the company get the technology to produce such a missile? Of course, I can simply say Serbia, and I will explain the matter very simply.

EDEX-2023
Egypt has been producing the Serbian suicide drone RAVEN 145 Loitering area denial weapon for several years, along with the NOVA missile.
Some were denying it, and others did not know that there is actually manufacturing of many Serbian and Chinese products for many years, and through this locally produced aircraft, Egypt simply used The destructive heads have a destructive head for the 155 LR GPK missile and other destructive heads are also used in other Egyptian munitions such as the
GPK 122
As for the Mid-course INS Terminal Guidance HH, it is a combination of the RAVEN 145 with GPS
The engine is a product of the Serbian company EDePro, most likely preferred over the British PBS Aerospace engines, which provide a series of engines for many other Egyptian guided munitions as well
This illustrates the philosophy of producing a product at a modest cost without spending on global research, large numbers and providing it locally in large quantities at a low final price, cheaper than importing even from China
The same idea is applied to a small Egyptian cruise missile mounted on CH-5 drones and HALE aircraft in numbers on the aircraft due to its low weight to provide hitting more than one target in one edition and also via cheap platforms instead of fighters
