Self-propelled mortar AMOS. Swedish-Finnish shotgun

The main problem of mortars at all steps of their existence has been mobility. The calculation could not manage to curl up and go with the position and for it to fall under the enemy's fire. With the advancement of technology the opportunity to install self-propelled mortars landing gear, and from that it was less confusing than I would like. Now "fouling" detection — mortar shell has comparable low speed and a specific line of movement of flight, which is why it becomes easier to find the enemy mortar position with the help of radar stations. Accordingly, after the discovery soon followed and stroke. Outputs are conspicuous were: reducing the time to prepare for shooting, and most importantly, the departure from the position, improving and accelerating the rate of mortar ammunition.

Sweden and Finland are represented by companies BAE Systems Hagglunds and Patria Weapon Systems, respectively, in the late 90's decided to work together to solve all problems at once self-propelled mortar. Problem was, to put it mildly, difficult, but both offices coped with it. Duties assigned followed by: Finns make themselves mortars, and the Swedes — the gun turret and related systems. The project is dubbed the AMOS (Advanced MOrtar System — Mortar system forthcoming). As the chassis for self-propelled mortar first elected eight-armored vehicle production Patria, and later the tower AMOS installed on the chassis of armored bay CV90.

Initially created two models of the gun turret. Both of them had two 120 mm mortar. All of their differences based on the fact that an instance of «A» had mortars with a muzzle loading, and mortar Layout «B» breech-loading. Apart from the features of the system of loading, were significant differences in the range of fire: breech-loading mortar thrashed for three miles further than the muzzle-loading. So Makar, the largest range combat AMOS at this point headed for 13 km. Polygon comparison tests 2-towers of the prototype were conducted on military vehicles with wheel chassis. Range, ease of loading and some other advantages of the layout «B» is not fast enough left fluctuations which version of AMOS will be the basis for the standard combat vehicle. Tower with a breech-loading mortars installed on the chassis CV90 — Swedish promising a unified platform for the whole family of armored vehicles. Once again, the tower «B» has confirmed their worth. Go with it and was able to learn the behavior of track platform at the set on her turret.

The system AMOS, as well as the rest of mortars, first created for firing from the closed position. For this reason, tower has only bulletproof armor. Yet, the designers have provided and the possibility of direct fire: both vertical leveling mortars likely in the range from -5 to +85 degrees. Guidance is provided on the horizontal rotation of the turret; dead zones in all this. Mortars are equipped automatic loading system, through which you can make all of the 10 shots within 4 seconds. For self-defense on the tower is installed 7.62-mm machine gun. Mortars can use all types of 120-mm mortar shells, provides standards of NATO, including the governed. It must be said, because of the peculiarities of ballistics existing mines and some moments of "anatomy" mortar bonded AMOS + CV90 highest firing range had to be reduced from 13 to 10 km. First tests of the new twin mortars could create a total of only 10-12 rounds per minute. Further development of the automatic loader over time is allowed to bring this figure up to 26 shots per minute.

Perhaps the most difficult part of the battle of the mortar team — calculates the performance of the shot, such as the angle of elevation. The composition of the combat unit AMOS comes to computing equipment, allowing comparable rapidly create a tip mortars. Also, the calculator may create a tip when firing on the move at speeds of up to 25-30 km / h In this case, an effective range of fire is reduced to 5 km. But the possibility of a major modern self-propelled mortar, which "show off" the developers is to prepare to fire on the move. In other words, all the necessary calculations and guidance tools, you can create a movement. Then follows a small station, a series of shots and the car continues to move. Argued that the precision with this method of firing is not worse than when shooting from a hundred percent motionless position. Of course, for such a firing computer must "know" the target coordinates and the coordinates of the place where self-propelled gun will fire. In today's widest dissemination of satellite navigation systems it looks real.

As a weapon system AMOS, as already mentioned, can be used no matter what mine is 120 mm NATO standard. High-explosive ammunition provides reliable defeat of the enemy, unprotected and lightly armored vehicles. In direct contact with a languid application of the technique can be severe damage, but it is faster than the exception, not the rule. In the long term would be to create other types of mortar, for example, temperature and pressure. But so far used only high-explosive ammunition.

The Finnish-Swedish cooperation in the development of AMOS mortar system was completed in that in the second half of the two-thousand years in the armed forces of the two countries entered a certain amount of self-propelled mortar. Finland in 2006 ordered 24 self-propelled AMOS, the total price of which exceeds the figure of 100 million U.S. dollars. Sweden was "economical" and a little later ordered only two 10-ka mortars. Breakfast order is fascinating not only the quantity: the first two 10-ka AMOS installed on the chassis CV90, but in the long term "carrier" mortar tower can be a platform SEP, developed at the current time.

For those customers who consider two mortars overkill, was created by modification of the firing module entitled NEMO (NEw MOrtar — New mortar). NEMO, unlike AMOS, has only one trunk. Other differences combat vehicle one way or another connected with this fact. What is curious, self-propelled mortar NEMO has been more popular and successful, if the initial AMOS. Own enthusiasm for the double-barreled mortar, except Finland and Sweden showed only Poland, and even then, it is not the first year can not determine with their intentions regarding the purchase thereof. The supply of NEMO, in turn, has entered into several agreements. Saudi Arabia has ordered 36 units NEMO, Slovenia longs to get two dozen self-propelled mortars, and the United Arab Emirates — 12 towers. Thus Arabia will be without the help of others to set the tower
on the NEMO chassis floating armored personnel carriers, and the UAE — for patrol boats. Curious method of implementation for the mortar.

As we see, the modules AMOS and NEMO can be mounted on various chassis. Namely, Poland is going to put them in armored vehicles KTO Rosomak. The developers mortars say their tower can also be installed on the chassis of the British infantry fighting vehicle FV510 Warrior and even the Russian BMP-3. For the installation of the tower with mortars special design configurations are required. With such besprityazatelnymi requirements "carriers" of systems AMOS and NEMO are excellent prospects. Their future depends on the willingness of potential customers.
