Guided bombs: a well-forgotten old
В news More and more often there are reports on the tapes about the use of guided or planning bombs in Ukraine by the RF Armed Forces, which are often also called "smart". In particular, literally today information was published about the successful defeat of armory warehouses of the Armed Forces of Ukraine in the Kherson region by planning FABs.
In Russia, there are guided bombs created as finished products, for example, UPAB-1500B, modular - "Grom" or equipped with a planning and correction module - UPAB-500.
There are similar ammunition in Western countries, in particular in the USA - GBU-39, SDB, etc.
However, despite the fact that the saying "smart bomb" suggests something ultra-modern and high-tech, the roots of these munitions stretch back to the 40s of the last century. The first guided bombs were developed in Nazi Germany and used by the Wehrmacht during World War II.
The pioneer in this field is the engineer Max Kramer with his FX-1400 aerial bomb. The development of the product started in 1940, and it was put into service in 1943.
The FX-1400 had four cruciform stabilizers in the middle of the hull and a box-shaped tail. The guidance system was represented by the FuG 203a "Strassburg" command radio receiver, and for visual observation, the bomb was equipped with an LED tracer.
This air bomb was dropped from a height of 4 to 8 km at a distance of 5 km from the target. At the same time, its accuracy was 26 meters.
However, although the FX-1400 is considered the first guided bomb, at about the same time in Germany, under the guidance of Professor Herbert Wagner, another similar Henschel Hs 293 ammunition was being developed. At the same time, it also entered service in 1943.
This model differed from the Kramer bomb in the presence of a jet booster, wings instead of cruciform stabilizers and the shape of the tail.
Wagner's idea was that the jet accelerator, turning on for 10 seconds, gave the product an additional speed of up to 190 km / h. Given the speed of the carrier, the bomb could accelerate to 360 km / h. In this case, the discharge took place at an altitude of up to 1,5 km and at a distance of 8 km from the target.
Both German guided bombs were designed to destroy large surface targets.
