A prototype self-propelled mortar was manufactured in Sweden

BAE Systems Hägglunds AB (Swedish divisions of the corporation) has completed the production of a prototype demonstrator 120-mm double-barreled self-propelled mortar Mjölner, reports bmpd with reference to the magazine "Jane's International Defense Review".

Mjölner is made on the chassis of an infantry fighting vehicle CV90. In the near future, the company intends to begin testing the system.

The contract for the supply of the Swedish army 40 self-propelled mortars was concluded in December 2016 of the year. The transaction value was $ 68 million.

In the Swedish army, Mjölner self-propelled mortars were given the designation Granatkastarpansarbandvagn 90120 (Grkpbv 90120), and their supply should begin in the 2019 year.

“Unlike the highly automated AMOS system, the Mjölner system is a rather simple double-barreled smooth-bore mortar with“ conventional mortar-type ”barrels with recoil devices and with manual loading with a muzzle (!) Part. For shooting using conventional 120-mm mines with a range of up to 9 km. For loading from the barrel, a sliding loading mechanism is used, delivering two mines. Shots are made consistently with a small interval, ”the article says.

At the same time, the long-term rate of fire of 10 shots per minute is claimed, up to a maximum of 16 shots per minute. Firing is possible only from a place (although it is alleged that reloading of the mortar is possible on the move).

According to the author, "mortars are placed in a rotating steel armor turret, and the turret will be rotated only by manual drive." Mass of the tower - 7 tons. Combat of 50 mines located in the rear of the tower, manual feed, there may be an additional ammunition in the body of the machine.

The crew of the car - 4 man (commander, driver and two loaders). Calculation when shooting is in the fighting compartment in a standing position in full growth.

What for? What practical function will it carry? In my opinion, the question of combat effectiveness is very controversial, because this is a very "convenient" target when compared with a standard mortar calculation.

Just a mortar (with muzzle loading !!!) in the armored hull, no more

a survey on combat effectiveness is very controversial, it’s a very “convenient” target when compared with a standard mortar calculation.

In my opinion you are confusing something. The “usual” 120mm mortar calculation, as we know from Russian practice, gave a mortar a glance, several fighters treat the surface with pickaxes, in order to set up the platform, others hide the Urals and unload the ammunition, then tuning, aiming and only after a dozen or two minutes begins sighting. Grkpbv 90120 drove up, after a few seconds there was already shooting, they shot 2 to 10 per minute, which is already weighty, but what if 4 cars? After 90-100 seconds, without any preparation they started off, changed their position, recharged, stop, volley, etc. on the go. And this is your "convenient" goal ??! For whom is it convenient? Moreover, in comparison with the usual 120 mm mortar calculation, which is not protected by anything, in which the deployment and folding of the calculation lasts an unacceptably long time. In my opinion, the Swedes did just what they needed, the excellent, highly protected base of the BTR CV90, thanks to the two barrels, the rate of fire at 30 min per minute, everything that can be simplified, but you also need to understand that this machine will be integrated into a common combat chain and receive target designation and tip from other allied compounds. Also, such a machine will be one of dozens of one regiment, where tanks and infantry fighting vehicles are at the front edge, 4-0km, then at a distance of 5-9km from the front line mobile mortars and other self-propelled guns at a distance of 10i and up to 70 + km, Mobile mortars can play a very significant role both in assaulting something and in defense, and it seems the Swedes again managed to create a kind of simple but very effective system. There are Nones in the Russian army and, thanks to their mobility, they are indispensable for the same airborne forces or rapid reaction forces. Nona's only problem is no armor. The Swedes feel good, they have been selling very successfully for a long time and they themselves use their beautiful CV90 platform, while the RF Armed Forces desperately need the Kurgan people and, accordingly, the Kurgan people with a mortar installation.

According to the author, "mortars are placed in a rotating steel armored turret, and the turret will be rotated only by manual transmission." The mass of the tower is 7 tons.

As I understand it, everything will be there on the hydraulics and with some kind of amplifier, apparently ... but even so, twirl the drifts of 7 tons ... well, I don’t know what kind of guy there should be.
This machine is like a tank in size, and a very “tasty” target for a fighter with the same RPG.

It’s easier to tighten the hull, as it seems to me, but if they decide to hide a car in the trench, then there will be problems.

Easier to tighten the case

With a probability close to unity, the translator misunderstood something. And "manually" does not refer to the rotation of the tower.
Because it is impossible to simultaneously have both automatic guidance and manual rotation of the tower

Hydraulic drives everywhere are changing to electric ones, on the same machine a manual tower rotation drive. Why it should cost some exorbitant efforts there, it is not clear, even in Leo2, whose tower is several times heavier and has a manual drive in order to use it in the "Stab ein" mode, that is, when everything is turned off (motor, APU) and is used only optics and manual drive. If everything is balanced and blurred in your mind, you can twist it with one finger. Moreover, if you want, you can always put an electric motor on a manual drive.

I believe this machine will not by itself wander around the battlefield, rather in the rear at a distance to its units that are closer to the front, tanks, armored personnel carriers, infantry, and the machine itself will be part of its own kind, maybe a pair of infantry fighting vehicles, or armored personnel carriers in defense , command vehicle, radars, etc. And it’s not so easy to burn the CV90 in full combat body kit, with screens, and grilles, on already and without tigi not weak Swedish RPG armor, even if somehow you can sneak up on the distance of a direct RPG shot. As for the gabbarites, so compare with the usual mortar calculation, consisting of the Urals pulling a 120mm mortar on wheels, in the back of the Urals, calculation soldiers are sitting on benches protected by a tarpaulin, next to the BC. When an ambush on a column of armored vehicles, a Swedish car can immediately start a battle, and the usual calculation in the Urals can die in the first seconds of the battle, from the fire of ordinary machine guns and machine guns, and if they are also tracers, they fire at B32, then the BC can undermine, and use in such a situation, a regular 120mm mortar that weighs more than 200kg is impossible. In my opinion there is no alternative to mobile mortars, such as this, Nona, in a modern battle, against a well-armed and trained enemy, armies, such as NATO, or already Chinese, there will be no front lines with fortifications, trenches and roadblocks in the event of a military conflict, but there will be the constant movement, the development of jagged tactics, the receipt and updating of combat information in live time, and I do not see a place there for such systems as Sled.

uh, and then how to charge from the muzzle? maybe with the treasury? Or will they climb out?

For loading from the muzzle, a sliding loading mechanism is used, feeding two mines.

Read the articles carefully.

We read carefully:

[Shura Sailors]

Chargers (two of them, in addition to the commander and driver) lay mines in the loading mechanism. If the trunks are raised at an angle from 45 to 85, loading is performed without changing the position of the trunks. But MULTI loading ...

[spirit]

Granatkastarpansarbandvagn what?))) reminded one funny comedy

[Lopatov]

In short, the Swedes quarreled with the Finns. Due to the reluctance of the latter to buy the Swedish superSAU "Archer" 8))))))))

The second option was considered AMOS too expensive. That is, they did the same as the Finns with “Archer” 8)))))

[corporal]

Quote: Spade

found amos too expensive

Possible.
Yes, and the new version turned out pretty good, anyway better than our “Sled”.

[Lopatov]

AMOS requires special ammunition. In principle, the same 120-mm mine, but with a special pallet to provide obturation. That is, slightly more expensive mines for "Mjölner", which use the standard. In addition, the AMOS in the automatic loader only has an insignificant part of the battery, and there is no possibility of changing the charge on these mines. Everything else is manual, by crawling with the letter "si" in the stern of the loader’s car

As I understand it, initially there were 4 options for a new self-propelled mortar: AMOS, open placement, a muzzle-loading turret and an analogue of the four-barrel Austrian SM-4
They abandoned the latter at once, three remained.
Of these, the average in terms of opportunities

[corporal]

Eh .. our at least openly honored
Everything is better than towed (transportable-roll-out).

[Lopatov]

Good video. You can see the pallets on the mines, and absolutely unacceptable working conditions of the loader when using non-mechanized styling. By the way, the Polish "Cancer" is also arranged, but there is only one trunk.
But "Nemo" does not have an automated combat station at all, only manually.

[san4es]

"Nona" is more universal

[Lopatov]

“Nona” is old, without ASUNO, therefore loses in all respects.

[karabas-barabas]

But at least it’s mobile and can change location quickly, unlike the same Sanya.

[Lopatov]

Mobility mobility is different. Mortar from the "Sled" can be easily rolled manually. And put it in a much more secure place than all those available to self-propelled mortars

[Brut]

And what is your rating of self-propelled mortars as a specialist?

[Lopatov]

There is no solution close to ideal (like new SGs like the Coalition and Donar) for mortars at the moment.
Or rather, no one can afford such a solution. Self-propelled mortar with fully automatic loading, high-speed ASUNO. Able to shoot both with closed OP, and used as a fire support vehicle by direct fire. Able to use both conventional mines and long-length mines like "Merlin". Protected from enemy precision weapons ...

Well, according to the criterion of "price-quality", Israelis come first. No wonder their "carriage" is so common

[Mih1974]

What the hell is "muzzle charging"? It can be seen that the state one, moreover, the presence of automatic calculation (possibly georeferencing) is very correct and it is desirable for us, here let MANUALLY hold off the propelling charges . It’s good for the camera, but in battle or in the second ten or more or less, it’ll frustrate more or less, and the speed from this drops very much. Again, what happens in the process of firing at them there on the floor heaps of heaps of bags of gunpowder? There was a video from Syria, it seems, when it seemed like a wad fell on the gunpowder scattered around the “nona” and everything flared up there. Fortunately, the crew jumped out and extinguished calmly.
Campaign Scandinavians again foolishly stint. They still do not have anyone to fight with. Or these stupid people are counting on "Finnish company 2.0", well then let them break off. He will sweep them away by order so they won’t have time to make a bark.

The video is Finnish AMOS. This is another machine, not the one that is discussed in the article.

To pull off is much faster than to tie, as we do. Everything else on the video is old ammunition. Now they have extra. bundles are protected from moisture. And we do not. With all the consequences.

Was it worth the fence to build a charging shotgun in caliber 120 on the basis of an infantry fighting vehicle from a muzzle ???
It seems that the Swedes still have a pre-oligory and thorny path to at least Nona ...
Something is not right here, treskoyedy darken.

[Lopatov]

Quote: Romanenko

This double-barreled gun is an order of magnitude safer than the Nona. It is due to muzzle loading
Not only that, it provides greater accuracy, greater responsiveness and less vulnerability to counter-battery fire.

[Thunderbolt]

For armor, anything is better than "dodging" fragments.
A high mobility gives more chances to take a new position BEFORE the enemy’s response, and not AFTER.
