Description
The Landsverk U-SH 405 is a rank V Swedish tank destroyer with a battle rating of 7.7 (AB) and 8.0 (RB/SB). It was introduced in Update 1.97 "Viking Fury" and is a prototype vehicle from the late 1950s. The key feature of this vehicle is the double high-penetration, fast-firing rocket launchers mounted on top of it, making it a force to be reckoned with for any tank it faces.
General info
Survivability and armour
The U-SH-405 simply cannot afford to take any damage, it will die instantly from pretty much anything. However, the ability to fire its high-penetration rockets with no reload time at all makes it very good at taking out any target, and even several targets at once if the occasion arises.
With only 2 crew members and only 10mm of armor at most, the U-SH-405 will die very easily, be it to aircraft, machine-guns, artillery, etc. As such, it is best to avoid frontal engagements unless necessary.

Mobility

|---|---|---|---|---|---|---|---|
| Forward | Reverse | Stock | Upgraded | Stock | Upgraded | ||
| Arcade | 82 | 11 | 5.7 | 128 | 172 | 22.46 | 30.18 |
| Realistic | 74 | 10 | 80 | 90 | 14.04 | 15.79 | |
With 80 km/h (49.7mph) 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).

Armaments
Main armament
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 10 seconds, making it able to kill several tanks of any type in just a few seconds, provided they are aimed properly.
The rockets are most efficient at close to medium range, over 600 meters, they start to become quite inaccurate. On top of the only 18 rockets, it is also fairly long to replenish them; as such, one should use them with caution.

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-caliber machine-guns) and aircraft. Some tanks in particular, like the American T34, T30 and T32, should be avoided because of their multiple .50 cals and high-survivability against the rockets.
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 later-on.
Pros and cons
Pros:
- Fast-firing rockets (Basically no reload at all between each rocket) with very high penetration
- Low-profile
- Good speed on roads
- The rockets are fast and have similar ballistic properties than regular HEAT/HE shells, making them very easy to aim
Cons:
- The HEAT rockets explode when they're already out of the tank, making the post-penetration damage very similar to APDS despite having 1kg of explosive mass
- Extremely weak armor and only 2 crew members (will instantly die from .50 cals and can die from 7.62mms)
- Only 18 rockets, and you may need several rockets to kill just one tank due to their late detonation
- You can only replenish rockets once you've used all 9 of them, and replenishing takes a fairly long time
- Awful power-to-weight ratio in realistic (15.7hp/t) making it quite slow off-road (30-35km/h) and unable to climb hills
- The rockets are ineffective at long range as they heavily deviate over time (even a mere 800 meters may prove difficult)
- Can be destroyed by hard collisions at high speeds
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.
