tell, both appeared invention Herman Korobov "ST device" and developed on the basis of his automatic TKB-059
If orange Machines Herman Korobov surprising for its bright "non-military" coloration, is another example of his authorship - the very concept. Three barrels in a row - it's overkill even for hunters, not to mention the army machine.
The reasons for the emergence of this "three-headed snake Gorynycha" usually write very little, at best sparingly mentioning, what"Weapon of such a concept developed in the USA on the program SALVO».
As they say in such cases - that is true, but not the whole truth. The thing is, that the American program "started" much earlier.
Experimental Machine TCB-059
Another 50-x, having been engaged in the generalization of the experience of the last World War II and is still running the Korean, American researchers have found some pretty unpleasant things. At first, it turned, that the actual distance in combat firing noticeably less, than previously thought.
fighters interviews and analysis of large amounts of terrain shown, what's next 300 yards (about 274 m) in combat, few fires - first, because it does not expect to get, and secondly, further and see a purpose such as running infantryman is not always possible.
Furthermore, when the average shooter shoots, then at a distance of more than 100 yards usually misses the mark because of incorrectly specified distance, improper preemption, stress, phases of the moon, and even a variety of reasons.
Even less reassuring steel efficacy studies avtoognya. Americans at that time were armed with rifles under the powerful cartridge .30-06. And if our military were dissatisfied with the accuracy of fire AK-47 when firing bursts, the American rifle in the full auto mode kicked, as the Soviet gunners did not dream in a nightmare. At a distance of 100 yards (about 90 m) almost two-meter board usually affects only the first bullet in the queue.
Experimental Machine TCB-059
One of the concepts, designed to improve the situation was a program of "volley". anticipated, that volley or queue with a high rate due to controlled scattering can partially compensate for errors arrow. for example, if a single bullet, flying past the enemy shoulder, except that it will frighten, then the salvo of five slugs with the same input data, Two of them have chances podranit foe.
It is within this concept, the American designer Stefan Jansson on the basis of the Belgian FN FAL rifle designed a double-barreled Winchester Salvo rifle, and already under the new cartridge 5,56 mm, but not familiar to us 5,56 mm NATO, and special duplex (dvuhpulny) patron T65.

IN USSR, as we have seen on the example of the history of the emergence of chuck 5,45 mm, for the main potential enemy rather closely followed developments. AND, of course, if so, Americans built a double-barreled broads, that our weapons should be even cooler. Even though it is just a "technology demonstrator" to test the concept overseas.
The weapon was developed in 1964 year in the Tula Design Bureau under the standard cartridge of caliber 7.62 × 39 mm. automatic TKB-056 (also known as "ST unit") executed in the arrangement bullpup, a three-row store on 45 rounds.
The main feature of the machine is the presence of three barrels, of which at the same time being salvo fire. The trunks are collected in a single carriage and have a common mobile automation system. firing rate reaches 1400-1800 rounds per minute. Cverhbystraya turn keeps the machine from deviations due to the impact, which increases the accuracy of fire.
triple- «DEVICE BZ» for burst firing
Need to say, that even though "ST unit" and developed on the basis of his machine TKB-059 hardly ever seriously considered by the military as a viable candidate for replacing AK, their appearance is a landmark not only for Herman Korobov, but in general for the construction of the national school of small arms.
At first, it is through them had to get our own results on the effectiveness of firing a volley / short vysokotempovoy queue, for many years to become the most promising direction in the development of domestic machine. Contest "Abakan" and the winner - automatic Nikonov "AN-94" - created just within this concept.
Besides, in these samples, Korobov has applied a number of non-trivial design decisions. The block of three shafts on a common carriage locked single wedge gate. Power is supplied from the original three-section shop, which during firing is also moved together with the receiver and barrel unit. With this return, "volley" three shots 7,62h39 mm perceived relatively comfortable.
But still a real rival AKM Korobovsky trehstvolka could hardly become. Although whether from Korobov opportunity to experiment not only with weapons, but also new duplex ammunition, like his American counterparts, perhaps, the results would have forced the generals to think about this perspective.
