Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The Sav m/43 is a Swedish tier 4 tank destroyer.

Swedish assault SPG. The vehicle was developed in 1941–1944. In March of 1944, Scania-Vabis received an order for the production of 36 vehicles. The first 18 vehicles were re-equipped from the Strv m/41 SII. Initially, the SPG was equipped with a 75-mm gun, but in March of 1946, all vehicles were re-equipped with a 105-mm gun. A total of 36 SPGs were manufactured and remained in service until 1973.

The Sav m/43 leads to the Ikv 103.

Player Opinion

Pros and Cons

Pros:


  • Good accuracy and Weapon handling with the 75mm long barrel gun
  • Combination of fast reverse speed and excellent gun depression is ideal for working a reverse slope.
  • Sports a very dangerous 105mm howitzer to tier 3's and most tier 4's
  • Great gun arc.


Cons:


  • Almost useless stock gun
  • Generally poor manoeuvrability
  • 105mm howitzer has almost 10 sec reload, along with lower HE alpha. Due to that, it has a lower DPM than most tier 4 TD's.
  • 105mm howitzer has the worst Aim Time out of all the Tier 4 derp guns.


Performance

Like the Ikv 72 the Stormartillerivagn m/43 plays somewhat like the SU-85. Once equipped with the 75mm long barrel gun, the Sav m/43 can perform as a sniper. The combination of excellent gun depression and a fast reverse speed means that the Ikv 72 can successfully park behind a ridge. Another choice is the 105mm howitzer, or "derp" gun. When mounted with this gun, the Sav m/43 turns from a sniper to a close range brawler. It can be compared to the Hetzer in some aspects. But, unlike the Hetzer, this has an almost 10 sec reload, even with equipment. Due to a sluggish traverse speed, players should be careful of their flanks.


Early Research

  • Radios carry over from the IKV 72. Mount them.
  • You will find that the stock engine and stock tracks to be very limiting. First get the engine, then your tracks. This will be very helpful for you, since it will boost your combat effectiveness indirectly.
  • After getting the engine and tracks, focus on the 75 mm long barrel. It will boost combat effectiveness immensely.
  • IF you find the 75mm to be lacking in damage, research the 105. This will unlock the Infanterikanonvagn 103. You can choose to use this 105mm or stick with the 75mm long barrel gun.
  • SKIP FINAL RADIO. it will unlock with Ikv 103.

Historical Info

With the start of World War Two, Sweden had seen success of the German and Russian assault guns, especially vehicles like the Stug 3. And so, in September 1941, a decision was taken that assault guns should be introduced to the Swedish army. The role of these assault guns would be to support infantry with mobile direct or indirect artillery fire, as well as to provide some anti-tank capability.

Studies began and it was soon decided to utilize the leftover L-60 tank prototype to test the new concept. The vehicle was finished in 1942 and was simply called by its army number designation as “number 62”. During its trials, the vehicle was tested with the 7,5cm Kan m/40 field gun and later the older 7,5cm Kan m/02. In 1943, the vehicle was re-designated to Stormpjäs fm/43 and was trialled with a 15cm recoilless rifle. The tests with this vehicle generally proved positive, but the weight limitations of the L-60 suspension meant that the vehicle could only provide its crew with protection against small arms, except for the gun mantlet, which was 50mm thick.

Stormpjäs fm/43
With 15cm recoilless rifle

It was decided to continue the project on such a vehicle, that could be equipped with heavier armor. Landsverk responded by proposing an assault gun, based on the L-62 SPAAG chassis, but it did not meet the protection requirements. Therefore, Landsverk made a new proposal, based on their new projected light tank, called Terro. This proposal was however also rejected, as the weight of such a vehicle would likely exceed 15 tons and that the production of new chassis would take too long. Instead, the new assault gun would be based on the Strv m/41 chassis. In fact, this option had been tested in 1942 with a full scale wooden superstructure being built around a Strv m/41 prototype and in 1943, a functional prototype was ordered.

Pav m/43 prototype

The prototype vehicle was ready by August of the same year. It was designated Pansarartillerivagn m/43 (Pav m/43), but was later re-designated to Stormartillerivagn m/43 (Sav m/43). It was equipped with the same 7,5cm Kan m/02 as the Stormpjäs fm/43, but only as stopgap measure, until a 10,5cm gun would be available. In March 1944, a decision was taken to convert the remaining Strv m/41-SII from the production batch to assault guns. A total of 36 vehicles was delivered between March 1944 and January 1945. During 1945-1946, the vehicles received their 10,5cm guns.

Sav m/44 with 10,5cm

When it entered service in 1944, the vehicle was relatively modern and completely sufficient for the infantry support role. It was equipped with frontal armor of 50mm thickness and with 15mm side and rear armor. It weighed 12 tons and had a 162hp engine, which gave it decent mobility with power-to-weight ratio of 13,5hp/t. It could also reach the top speed of 45kph. Its main drawback was perhaps its lack of a decent gun during WW2. Later in its life, the vehicle had its engine replaced by a weaker 142hp engine, which was more reliable. The vehicle was in service with the Swedish army until the 1970s when it was replaced by the Ikv 91.

There were however more projects derived from the Sav m/43. In 1944, plans were made for a conversion of the Sav m/43 into a 10 ton tank destroyer. The vehicle was to share the same chassis with the Sav m/43, but with the engine moved to the front and the superstructure to the rear. The rear superstructure was to have an open rear part, which had a platform, that could be folded down, so the crew could service the gun. The vehicle would be armed with the 7,5cm L/54 Pvkan m/43 anti-tank gun, or another gun of equal power. This would give the vehicle the ability to fight most modern tanks of the time, while keeping the weight as low as possible. In fact, the Sav m/43 prototype was converted to this configuration.

“Trätoffelvagn” with 15cm m/44 Sav recoilless rifle

The vehicle was tested between circa 1944-1945 and was initially armed with the 7,5cm Pvkan m/43, but it never entered production. So, instead the prototype was trialled as a heavy assault gun with a 15cm m/44 Sav recoilless rifle. This weapon fired a 40kg high-explosive shell, which was rather impressive. The trials were however short, as it was quickly realized that the backblast of the weapon caused major problems. Instead, the prototype would serve as a training vehicle for the Sav m/43 crews. It is likely that it was during this time it received its nickname “Trätoffelvagn”, meaning clog wagon. It is unclear as to what happened with the vehicle after this point, but I think it is safe to assume that it was used as a target at a firing range.

There is however yet another assault gun project, derived from the Sav m/43. In late 1949, Bofors created a prototype for the next generation of assault guns. The vehicle seems to have been private joint venture between Bofors and Landsverk and the result was a 20 ton vehicle, armed with a 120mm autoloader. The vehicle was based on the same suspension, albeit extended, as the Sav m/43. The vehicle had a 6 round autoloader 120mm gun, which had a muzzle velocity of 550m/s. The gun could traverse 15 degrees to each side and could depress to -10 deg with an elevation of +25 deg. It is unclear why this vehicle was never purchased, but it is possible that this was because of problems with the complexity and cost of the autoloader.
