Description

The Landsverk U-SH 405 is a rank V Swedish light tank with a battle rating of 7.3 (AB) and 7.7 (RB/SB). It was introduced in Update 1.97 "Viking Fury". It is a prototype vehicle from the late 1950s based on the Unimog 404 truck chassis. The key feature of this vehicle is the dual, high-penetration, fast-firing rocket launchers mounted on top of it, making it a force to be reckoned with for any tank it faces.

The U-SH-405 simply cannot afford to take any damage, it will succumb instantly to pretty much anything besides light machine guns. The weapons can be destroyed by anything if intentionally targeted. With only 2 crew members and only 10 mm of armour at most, the U-SH 405 is very vulnerable to aircraft, machine-guns, artillery, etc. As such, it is best to avoid frontal engagements unless necessary or surprise is guaranteed.

However, the ability to fire its high-penetration rockets with no reload time at all can create an extremely effective horror effect, which might prevent enemies from advancing and may force them to rely solely on airstrikes and artillery.

The car is also very short with weapons on the very top and can easily hide behind dead tanks or random rocks found on the battlefield, or even attack over hills before some tank commanders feel comfortable with firing back.

With 80 km/h (49.7 mph) forward and 157 horsepower for 5.7 tons, the U-SH 405 has good mobility in Arcade. However, in Realistic, the top forward speed is 73 km/h (45.3 mph) for 90 horsepower, making it good on-road but just decent off-road and awful at climbing hills. The reverse speed is 9 km/h (5.5 mph), which works most of the time but can still be too slow in some situations (especially off-road).

In AB, it is imperative for this vehicle to research as many turret stability upgrades as possible, because that will allow for attacks on the move. The stock turret slewing rate is also quite poor, so an early upgrade to it is very nice to have. As such it might be best to rush "Horizontal Drive", "Suspension" and "Elevation Mechanism" there. In RB, it might be better to research "Brake System" instead of "Suspension", because it is very difficult to fire on the move in RB without slowing down first.

"Parts" are necessary to fix the weapons if someone uses machine gun on them, as they are very fragile. "FPE" is very situational but might still help when attacked from behind by unexperienced opponent. After that, mobility upgrades like "Filters" or "Engine" are generally most useful due to increased ability of a flank attack, but in AB "Crew Replenishment" can be equally useful with reserved playstyle, as it will allow to make one mistake and maybe survive. The rest of upgrades simply enhance an ability to be useful as a support.

Main article: Oerlikon Typ 3Z 8Dla

The U-SH 405 has for sole armament two 81mm rocket launchers, but it still has very impressive firepower - especially considering that it is a light car.

Each launcher comes with 9 high-penetration rockets that have similar ballistic properties as regular HEAT shells. The rockets can be fired all at once in less than 4 seconds, making the car able to annihilate several tanks of any type in just a few seconds, provided they are aimed properly. Even without proper aim, it is possible to brute force almost any heavy tank at the cost of the entire magazine.

It is very important to note, that unlike majority of rocket tanks, U-SH 405 has gun depression and can actually fire downwards and off some gentle slopes. This enables a lot of suppressing fire scenarios unavailable for other rocket tanks and particularly valuable during any hill battles.

The leeway in gun depression also allows the tank to fire on the move in AB mode; with minimal effort once the gunner has maxed out "targeting" with expert training and the weapon lifting speed was upgraded. In RB, fully upgraded tank can sometimes fire on the move off completely flat surfaces.

The rockets are most efficient at close to medium range, as over 600 m it becomes quite difficult to aim due to poor optics zoom. On top of that, it is quite tempting to just fire them in volleys, wasting the ammunition on overkill in process. However, at long range and with some extra effort they can also be launched over car's own cover without any possibility of enemy retaliation.

Both guns are on separate triggers, and so it is very recommended to unbind "fire additional weapon" from "fire main gun" button (left mouse button by default). This allows to strategically manage ammo reserves, as only one gun can be resupplied with rockets at the same time and only when that gun is completely empty.

In AB, the rearm time for one gun is about 34 seconds and will start as soon as the gun is emptied; in RB it can only be rearmed on a capture point and this takes about 40 seconds.

Msg-info.png The main gun (left) is resupplied first regardless of a situation and will prevent rearm of the secondary gun as soon as it is empty, even if the right gun was 1 second away from being done.

Because of this, spray-and-pray tactic with both guns at once is not very viable, unless trying to take down as many tanks as possible without concern for future survival. To avoid randomly running out of ammunition in AB, empty main weapon first or leave one rocket in the magazine until the right gun rearmed.

HEAT rockets are vastly superior to HE rockets, as they can take out much more targets reliably, but it is possible to use HE in rank VI and beyond, as tanks start to have weaker roof armour again.

Usage in battles

Thanks to the very high penetration of its HEAT rockets, the U-SH 405 can kill any tank it faces from pretty much any angle; this, combined with its near-instant reload and high on-road speed gives it great flexibility. However, the vehicle can be killed by anyone and anything, the main threats to the U-SH 405 are American tanks (and any other tank that has high-calibre machine-guns) and aircraft. Some tanks in particular, like the American T34, T30 and T32, should be avoided because of their multiple .50 cal MGs and somewhat high survivability against the rockets. Any tank that can survive inaccurate HEAT volleys (like the BMP-1) should be immediately attacked into turret or avoided.

The low post-penetration damages require one to aim at a tank's critical spots (such as the ammo storage or the gunner) if they want to disable/kill the target with only 1 or 2 rockets. Fortunately, the near-instant reload allow for several follow-up shots if the first rocket did not do as well as hoped.

The good mobility and low-profile makes the U-SH 405 very good at flanking and relocating in general, and the high firepower makes it devastating on unaware targets.

The U-SH 405 works best at supporting allied vehicles as they can draw attention away from itself, but the limited amount of ammunition forces it to stay relatively near strategic points to be able to replenish its limited ammunition count.

In arcade mode, it is possible to fullfill many roles, from being a roadblock which suppresses any tank trying to leave cover from behind a rock, to becoming a literal fan of rockets crashing into unaware enemies from the side as they converge on a choke point. If you do not have any solid plan, but also do not wish to simply rush enemy team, try to find some kind of bunker or high impenetrable building to hide behind as soon as possible, as it is very likely that all aircraft on enemy team will hunt you simply out of spite or because of the low armour amount. Getting bombed for no good reason without releasing rockets onto enemy tanks first will not help your team. You should also take in consideration that only one gun can reload at once, either use rockets sparingly to stall enemy tanks for as long as possible until the other gun reloaded or destroy them by using both and make a complete retreat. Make sure to not use the last rocket in the left gun until the right one reloaded to avoid being stuck with no ammo (You still can use all rockets in the right gun while left one is reloading )

Pros and cons

Pros:

  • Low-profile, can be easily concealed
  • Almost completely silent, making it easy to sneak up on enemies undetected
  • Has gun depression unlike most of other rocket tanks
  • The rockets are fast and are very easy to aim at medium range
  • Good speed on roads
  • Fast-firing rockets (Can fire two at once, basically no reload at all between each rocket for each gun) with high penetration
  • Can reload anywhere in AB (like ATGM tanks)

Cons:

  • Extremely weak armour and only 2 crew members (will nearly always instantly die from .50 cal MGs)
  • Small, light frame and small crew lets it easily be destroyed by hard collisions at high speeds or crushed by heavier tanks
  • Awful power-to-weight ratio in realistic (15.7 hp/t) making it quite slow off-road (30-35 km/h) and barely able to climb hills
  • The HEAT rockets have limited post-penetration damage
    • Only 18 rockets, and you may need several rockets to break just one heavy tank
  • The rockets are ineffective at long range due to poor optics zoom and low ammo count
  • You can only replenish rockets once you've used all 9 of them, only for one gun at once, and it takes a fairly long time
  • No aim assist in AB, as with all rocket tanks

History

Devblog

Development of the U-SH 405 began in the late 1950's, after Landsverk and Daimler-Benz formed a cooperation to further develop the Unimog 404 truck into a family of different military vehicles, ranging from APCs to dedicated tank hunters. Development was initially headed by the Germans, but in 1958, Landsverk took over the lead role in its development.

As part of the ongoing development, Landsverk came up with a dedicated tank hunter variant of the vehicle in 1960, fitted with a pair of Oerlikon 81mm rocket launchers, originally developed for aircraft and helicopter use. A single prototype of the machine was built and trialed, but no production orders were issued.

However, the APC version of the U-SH 405 saw more success, being ordered by the Belgian armed forces in limited numbers. Despite placing an order for around two dozen vehicles, due to various geopolitical reasons, Belgium only received fewer than half of the machines initially ordered. The remainder of the machines built, but not shipped to Belgium were later on sold to the Irish military in the early 1970's, which used the vehicle until 1978 before retiring it.
