Standalone Swedish Ground forces tree

A Swedish Ground forces Tech tree

vdDWIWY.jpg?w=620&ssl=1

Welcome. Im sp15 an amature historian, for the past year or so I have been looking at the possibility of creating a Swedish Ground forces tree for War thunder. Gaijin actually made an official statement on the viability of such a tree in War Thunder: The Shooting Range Episode 67 stating “Sweden had some great machines of their own but not enough to give them a separate tech tree”, Im here to disprove that statement, and in the process outline how a Swedish tree could be built.


I have previously worked on the research and development of the Swedish tech tree in a game that shall not be named, and some of you might recognize me from my work as a writer on the For the record and Status report blogs where i wrote a series of articles on Swedish tanks. But anyway lets get to the good part shall we?

The tree

As of the current revision the tech tree features 4 lines consisting of medium tanks/MBT's, Light tanks/tank destroyers, tank destroyers/ATM's and Self propelled AA guns as well as a number of premium vehicles. The placement of vehicles in the tree should be taken with a grain of salt as they are likely to change. There are also some vehicles that might not be suitable for implementation due to requiring additional mechanics to work properly, specifically the UDES XX20. And of course there is no guarantee that if the tree makes it into War Thunder it will look like this.

 

There is also a real posibility of adding Swedish aviation naval tech trees and i can reccomend this thread if you are intrested in what a Swedish air tree could offer.

MEDIUM TANKS

Spoiler

Reserve: Strv m/31

X408EGg.jpg?w=620&ssl=1

By the time of its delivery in 1934 the strv m/31 was arguably the most modern tank in the world, the design featured sloped armor and made extensive use of welding in its construction which was rare for the time. it had a radio, Its soft suspension allowed a 40 kph top speed and it had good mobility in terrain. But the transmission as well as the tracks were fragile and hard to repair, and changing the transmission required the engine and fuel tank to be removed first. During winter conditions snow would build up in the drive wheel causing the tank to lose its tracks. The extensive use of foreign components in the design meant that spare parts had to be imported.

 

Between 1935 and 1939 the tanks were stationed at the I2 Göta Livgarde tank battalion where they ended up mostly serving as training vehicles due to their reliability issues. During ww2 there were plans to convert the m/31’s to command tanks but nothing ever came of it. Ultimately the strv m/31 ended up being somewhat underwhelming but the experience gained from its construction would prove to be an important lesson for both the Swedish army and Landsverk. Landsverk would go on to use this experience in the making of the L-60, a modified version of which ended up replacing the Strv m/31 in 1938.

Rank 1: Lago I/Lago I H

DWmo8CY.jpg?w=620&ssl=1

Originally built in 1940-41 for the Hugarian military the Landsverk Lago was the first true swedish medium tank design. Though it was never put into service the Lago prototype would serve as a testbed for the development of the Strv m/42 and Pvkv m/43 and saw extensive use by the swedish army in this role during 1941-46. The initial design of the Lago was basically a scaled up version of the Landsverk L-60 design with a enlarged, reworked hull and turret. However as the project continued the hull and turret was given a more rounded apperance and the armament was changed to a Hungarian 40mm gun. Eventually parts of the hull front and the engine compartment was completely redesigned as well. Had it been completed the tank would have been armed with a 12,7 mm hull mounted machinegun and two 8 mm mg's in the turret in addition to the main gun, however since the hungarian military backed out of the project the Lago ended up being armed with what was available, which meant a 37mm main gun.

 

The lago was Initially equipped with a German electromagnetic gearbox and a pair of Scania-Vabis 1664 engines outputing 284hp which gave the 18,3 ton vehicle a top speed of 45 kph. In preperation for the heavier Strv m/42 the Lago was rebuilt with a hydraulic gearbox and the more modern Scania-Vabis L 603 engines rated at 324hp (this version was named Lago I H). Durig testing with the new powertrain the Lago was able to achive a sustained top speed of 55 Kph, though it was later limited to 45 kph as the gearbox proved unreliable at higher speeds. Though the lago may be a bit of a unremarkable vehicle to start the swedish tree it should still prove a decent rank 1 tank.

Rank: 2 Strv m/42 TV/Strv m/42 EH

EUofkFM.jpg

By the start of 1941 it had become clear to the swedish military that the Strv m/38, 39, 40  would need to be supplimented with a heavier tank design which could stand up against the increasingly heavily armed and armored medium tanks of other nations.
Since the Landsverk Lago design was already completed and available it was decided that it would serve as the basis for the new tank.

A number of compromises had to be made when adapting the Lago to the new requirements, due to strategic mobility concerns the tank's combat weight was limited to 22 tons which did not allow for the requested armor thickness. This also meant that the width of the tank or it tracks could not be increased which resulted in steering issues and a rather high ground pressure.

 

During its production run of 282 tanks from april 1943 trough January 1945 there were three variations of the Strv m/42. The first batch ordered in 1941 from landsverk was equipped with a German electromagnetic gearbox and dual Scania-Vabis L603 engines. This version would be named Strv m/42 TM (standing for twin engines magnetic geabox).
the German gearbox would prove to be unreliable to the point that it was suspected that the gearboxes had been sabotaged. These vehicles would later be converted to use one of the other types of geabox.

follow up orders in 1942 resulted in the creation of two new variants one which replaced the electromagnetic gearbox with a hydraulic one,these became known as TH (twin engines hydraulic gearbox). The other was fitted with Volvos new A8B engine in addition to the hydraulic gearbox which was called EH (Single engine hydraulic gearbox). In 1946 some of the TM vehicles were refitted with a mechanical gearbox which created a further TV (twin engines mechanical gearbox) variant

nhuAxmn.jpg

As with the Lago design the crew of the strv m/42 consisted of a commander, loader and gunner in the turret with the driver in the hull, in addition the tank could take an extra crewmemeber to man the hull machine gun.  Besides the hull mg the armament consisted of two coaxial machineguns as well as a rear facing machinegun. For the main armament a short 75mm gun roughly comparable to the German 75mm L/28 had been chosen as a compromise between armor penetration and HE preforamnce. Notably the main gun of the Strv m/42 was capable of 15 degrees of gun depression.

 

The armor of the Strv m/42 consisted of 55mm of rounded armor at the front and the sides and rear ranged between 30-20mm, this gave it armor roughly comparable to the sherman and Pz 4. The mobility of the strv m/42 was quite good with the TH and TM versions achiveing a power to weight ratio of 15hp/t and the EH version with the more powerful volvo engine getting closer to 19 hp/t, all versions had a top speed of 45 kph however. In the end the Strv m/42 was a mixed bag, It was certainly a impressive achivement for a nation with little to no tank building experience like Sweden, but due its tething issues the tank wouldnt reach its full potential untill after the end of ww2. Even then the compromises made during its development meant that it was never really as good as the other medium tanks at the time. Still as the first medium tank adopted by the Swedish military the strv m/42 marked a imortant step forward as it proved that Swedish industry was able to design and produce its own tanks even without any outside help.

Rank: 3 Strv m/42 "Delat torn"

uwP8SVw.jpg

Already before the start of production for the Strv m/42 there had been some research into replacing the short 75mm gun chosen in 1941.
By September of 1943 the Bofors company was tasked with developing a new turret for the Strv m/42, this turret would make use of the new high velocity 75 mm Pvkan m/43 gun that was in development at the time and also be equipped with a automatic loading system for the main gun.

The first draft for the new turret was ready by the 22nd of March 1944. This turret featured the 75mm Pvkan m/43 gun mounted outside the enclosed part of the turret.
Essentially the gun sat in a sort of cradle in the middle surrounded by the commander and gunners position on the right and the loader’s position on the left. Due to the strange configuration, this new turret was nicknamed “delat torn” (Divided turret).
The gun was equipped with a automatic rammer fed by a five round magazine which would be reloaded by the loader. The gun had an estimated mechanical rate of fire of 20 rounds per minute and In total, the tank carried 42 rounds of ammunition.

 

By late 1944 a wooden mock-up of the “delat torn” had been finished and mounted on a Strv m/42 chassis. A functional prototype with some minor changes to the design had also been ordered by KAFT with an estimated delivery time of spring 1945. But the work on the prototype turret was slow and the originally intended delivery date could not be kept, in fact the prototype turret would not be ready for demonstration untill May 16th 1946

uauyLvi.jpg

Despite increasing the weight of the Strv m/42 by another ton the new turret was sucessfull in improving the firepower of the Strv m/42 immensly without adversely impacting the mobility of the tank. The Automatic rammer worked well during the testing and did offer a distinct advantage in rate of fire over a traditional gun, in fact during trials the autoloader was able to fire 4 rounds in 8,2 seconds. The Pvkan m/43 also offered a huge advantage in penetration compared to the Strvkan m/41 especially with the improved penetration of the APDS projectile introduced in 1949.

 

There were drawbacks to the "Delat torn" hower. Due to the way the loading system was constructed there was no way to unload the magazine from inside the turret, meaning you were stuck with whatever ammunition type you had loaded untill you had fired all 5 shells. The system was also hard to seal from the dust thrown up when firing the main gun.

Ultimately the prototype "Delat torn" turret would be canceled after tests and troop trials between 1946-1948.

Rank 4: Strv 81

strv_81B-5web.jpg

On the third of may 1953 the Centurion started its 50 year service history with the Swedish military, a total of 240 Centurion Mk.3's and Mk.5's were adopted under the designation Strv 81. The only modifications these tanks recived for the first 10 years in service was minor changes to the equipment and radios, they otherwise remained identical to their British counterparts.

 

No strv 81 was fitted with atgm's in service, however one vehicle was experimentally fitted with 6 Robot 52 ATGM's in the late 50's. This version should not be ATGM armed (if anything the atgm armed version should be renamed and moved to the swedish tree to serve as a premium)
 
 

 

Rank 5: Strv 102

strv_102-2.jpg

In the early 60's all strv 81's were upgraded to Strv 102 standard. This meant the reworking of one of the ammo racks, a change of radios and most importantly the addition of the 105mm L7 gun. In ingame terms this vehicle would be a Centurion Mk.3 with the firepower of the Centurion Mk.10

 

 

Rank 5: Strv 101

strv_101-4web.jpg

in 1960 sweden would purchase 110 Centurion Mk.10 to suppliment the Strv 81's. The main differance that set the Mk.10 apart from the older Mk.3's sweden had been using was the improved hull armor from 76mm to 120mm for the hull front and the introduction of the legendary Royal ordinance L7 gun. Other changes included a new improved cupola, a different shape for the mantlet and a rotating turret floor.

 

 

Rank 5: Strv 103A
E09L9CH.jpg
First produced in 1966 and entering service the following year the Strv 103A marked a distinct departure from conventional tank design. Instead of using a turret  the Strv 103 was designed with a suspension and steering system capable of quickly and accurately laying the fixed gun.

 

by relying on the ricochet effect that happens at very shallow impact angles instead of pure armor thickness the frontal armor of the strv 103 became immune to the standard APDS ammunition of the 105mm L7 at ranges over 800m and was said to be resistant to rounds up to 12cm APDS at longer ranges. Another uniqe feature of the Strv 103A was the use of armored "ribbs" on the upper glacis. These 30mm tall and 40mm whide "ribs" strengthened the underlaying 40mm armor plate and also provided a disintigating effect to incoming shells thereby decreasing their effectiveness.
Cmc45dX.jpg

The Strv 103 was fitted with an automatic loading system which fed from two magazines of 20 and 25 rounds respectively in the rear of the tank, however there was a third 5 round magazine used for smoke round that had to be operated by a hand crank used by the rear driver. The autoloader was capable of a sustained rate of fire of 20 rounds per minute.

 

The use of a fixed gun allowed the instalation of a extended barrel compared to the Standard L7 used on the centurions, this allowed for a higher muzzle velocity and a increased effective range. The secondary armament consisted of two coaxial machineguns mounted in the hull and a single machinegun mounted  onb the rotating commanders cupola.

FhdHI2f.jpg

The Strv 103A was the first tank to be produced with gas turbine engine, the small engine compartment had not allowed the use of a sufficently powerfull conventional engine so instead a combination of a gas turbine and a smaller internal combustion engine had been chosen. The specific engine featured on the Strv 103A was however underpowered as it only provided the nearly 40 ton vehicle with 540 horsepower. The need for a better engine had been recognised as early as 1964 with the preproduction series. In 1970-1972 all of the 70 Strv 103A's would have their gas turbine engine replaced as part of the upgrade to the Strv 103B standard

Rank 6: Strv 103B

K86gl6L.jpg

In 1970-72 the strv 103 truly entered production with the B version. The main change from earlier models was the upgraded gas turbine engine which now produced 730hp compared to the earlier 540hp which added some much needed mobility. The Strv 103B also introduced the built in dozer blade for every third tank, this not only added to the armor protection of the vehicle but also made it possible to dig in if neccesary.

ePSijPC.jpg
Another feature first available for the Strv 103B was the "armored fence" which consisted of 30mm in diameter armor steel bars that gave extra protection against mainly HEAT ammunition and ATGM's. The existance of this additional armor was kept strictly secret during the whole service life even from the crews

In addition to reliability improvements a number of modifications were made these included:

 

- New engines

- New Dihel tracks

- Additional fuel capacity and side protection

- The introduction of a integrated lazer rangefinder for the gunner

- Dozer blades were fitted to all tanks instead of 1 in 3

- A improved gearbox

Essentially the same vehicle as the Leopard 2A4 in the german tech tree but with some visual difference's. With the Swedish purchase of the Strv 122 in January 1994 a decition was made to simultaneously lease 160 used leopard 2A4's from the German army for the mechanized brigades. All tanks were delivered before the end of 1994 and were continuously phased out as the Strv 122 could be delivered, most Strv 121's were mothballed by the year 2000 and in 2011 the leasing contract ended, at which point 20 tanks were purchased by the Swedish army for conversion to armored recovery vehicles, engineering vehicles and bridge layers.

Description

Originally developed by the Swedish AB Landsverk company for the Irish free state the L-60 was a very good tank for its time. Its new suspension, small size and weight gave the tank excellent mobility and a top speed of 45 kph. The armament consisted of a newly developed 20mm Madsen automatic cannon and a coaxial 8mm Madsen machine gun which was better than comparable tanks at the time. In total, the tank carried 240 rounds of main gun ammunition and 3000 rounds of ammo for the coaxial gun. The main flaw of the design was perhaps the armor, which was only designed to be able to withstand .303 machinegun fire. This translated to a maximum thickness of 13mm for most of the hull and turret.

 

The Swedish army started showing interest in the design during 1936. A delegation was sent to study the vehicle in early 1936 and this led to mobility trials in June of 1936. The design was praised for its good mobility, optics and accuracy though some areas of improvement were noted. In particular, some minor changes needed to be made to the suspension and it was requested to add a commanders cupola. An order for two Swedish L-60 prototypes was placed in July. These would be significantly reworked compared to earlier models. The hull was changed to fit a Swedish-built 142 hp Scania-Vabis engine and a new turret from one of Landsverk’s armored car designs was installed. There were also some minor changes like the expanded drivers position. The successful trials of these prototypes in August of 1937 led to an order of 15 production vehicles with a 37mm armed turret. Internally at Landsverk these were called L-60 S but they received the army designation Strv m/38. The deliveries of the Strv m/38 started in August of 1938.

Description

With the German annexation of Czechoslovakia in 1939 90 TNH-sv (pz.38t aufs s) ordered by the Swedish army fell into german hands. To make up for these tanks the Swedish army placed an order for 100 units of an improved L-60 with Landsverk. The tank was largely the same as the Strv m/38 but was now equipped with an automatic gearbox, a redesigned engine compartment, and a new turret with improved elevation angles. In addition a applique armor package was developed which improved the frontal protection to 40-50 mm when equipped, which drastically improved the survivability of the tank.The vehicle was designated Strv m/40L by the swedish army and “L-60-S III” by Landsverk. A total of 100 tanks of this type were produced between 1941 and 1942.

Rank 1: Strv m/40k

IdfE3O8.jpg

Description

By 1943, Landsverk started to produce a heavier tank design and no longer had the capacity to produce the L-60 series of tanks, so instead, their production shifted to Karlstad Mekaniska Werkstad. The L-60 design recieved another overhaul and the suspension was improved to the point where the applique armour could be built in. Other than that a new, more powerful engine was fitted, the result of which was making the vehicle longer. This tank model was designated Strv m/40K by the army (and L-60-SV by Landsverk). 80 Strv m/40K tanks were produced between 1943 and 1944 and this was the final version of the L-60 to be produced.

Rank 1: Strv m/41-S/I

strv_m41-1.JPG

In 1939 the swedish military ordered 90 Czechoslovak TNH tanks, alongside the 20 improved L-60 tanks from Landsverk. But before any deliveries could be made, the Germans occupied Czechoslovakia and seized the tanks for themselves – they were used during the French and Russian campaign as Pz 38(t) Ausf.S. This meant that Sweden would have to turn to the domestic L-60 design yet again and soon, another model of the L-60 was ordered into mass production. But after drawn-out negotiations with the Germans, Sweden was finally able to get a license for the production of the TNH in December 1940. In 1941, 116 TNH tanks were ordered, they were to be produced by Scania-Vabis. Due to serious delays however, first vehicles were not delivered until December 1942 with the last being produced in late 1943.

The vehicle was designated Strv m/41-SI and was considered superior to the Landsverks L-60 designs. The vehicle weighed 10,5 tons and had 25mm of frontal and 15mm of side and rear armor. It was powered by a Scania-Vabis 1664 engine, producing 142hp and was armed with the same 37mm gun as the L-60 tanks. The vehicle had good mobility and could reach maximum speed of 48kph.

Rank 4: Strv 74

strv74-2.jpg

Entring service in 1957 the Strv 74 was a modernization programme for the strv m/42 which started in the mid-late 1950s. The strv 74 would replace the engines, turret, main gun and suspension of the m/42 in a effort to increase the lifespan of the vehicles. Unlike the earlier "Delat torn" turret the Strv 74 would take a more simpler aproach by using a enlarged conventional turret without the autoloader of the earlier design. The new turret would be fitted with a modified version of the 75mm L/60 Lvkan m/37 anti aircraft gun which offered penetration of up to 260mm at 90 degrees using APDS ammunition. The new turret was also able to retain the 15 degrees of gun depression found on the m/42.

strv74_klockfjader.jpg
The armor remained largely the same as the Strv m/42 but due to weight constraignts the new turret had only 20mm of all round armor protection. Unlike the m/42 however the hull machinegun port was welded shut and the position removed to allow for more ammunition to be carried. Due to reliability concerns only the twin engines Strv m/42´s were converted to Strv 74's however these engines were upgraded with a fuel injection system which added 100hp per engine compared to the earlier design. Despite this the power to weight ratio actually decreased as the improved suspension and new turret increased the weight to 26 tons.

Rank 1: Sav m/43 1944

ScU2CCa.jpg

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.

 

In 1943 a functional prototype based on the Strv m/41 chassis was constructed. 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. These were initially fitted with the 7,5cm Kan m/02 as stopgap measure until they could be replaced by a 10,5cm gun in development by Bofors.

It was believed that this vehicle could replace towed infantry guns, but to achieve this, the new assault gun needed to be as cheap as possible, so that numerous vehicles could be built. Therefore, it was decided to go with a very lightweight design, no heavier than 6 tons and to use readily available parts wherever possible.

 

The initial version had a crew of three and a weight of 6 tons, it was however a rather preliminary design, since no gun or radio have been decided for the vehicle. As the development of the vehicle continued, the superstructure was redesigned and the crew increased to 4. Next, there was the question of its main armament. Three options have been considered. First, the same 75mm gun, that had been used on the Strv m/42. Second was a newly developed 84mm gun, which was considered in 4 variants with different muzzle velocities, or a modified version of the 105mm m/40 howitzer. Of these options, the 84mm was the preferred option, but due to the need to develop the gun from scratch, it was decided to arm the initial prototypes and production run with the 75mm gun. By the end of 1949, most of the issues with the design were worked out and preparations were made for the construction of a prototype.

 

The first prototype was armed with three 8mm machineguns and was finished in early 1950, this armament was however found rather lacking and the prototype was soon refitted with a 75mm gun. The rearmed prototype weighed 6,5 tons and was powered by a 105hp Volvo engine, that gave the tiny vehicle a power to weight ratio of 17hp/t and an impressive top speed of 60kph. As you can imagine, the low weight did not allow a lot of armor – in fact, the thickest armor on the vehicle was only 19mm on the upper front, with only 7mm at the sides and 5mm at the rear. Perhaps the most impressive feature of the Tankett fm/49 was the gun depression, that could reach a massive -25dg, which was actually more than the elevation, which only reached 20dg. However, the gun traverse was rather poor with only 10dg of traverse to each side.

 

The tests of the prototypes continued well into 1950, but concerns arose about the low armor layout and it was decided to rework the frontal armor, so that it had better sloping. The second version of the vehicle, which incorporated these improvements later became known as Ikv 72 (infantry gun carriage). The main changes from the earlier model were a slightly reworked hull with a larger crew compartment and the use of a 145hp Ford V8 engine. The vehicle also became considerably heavier with a total weight of 8 tons, but with a better power to weight ratio of 18hp/t and slightly lower top speed of 57kph. In 1953, this vehicle was ordered into production with the first series of 36 vehicles following within a year.

In 1942 the Swedish army identified the need for a dedicated tank destroyer with higher firepower than the strv m/42. The new tank destroyers would be under direct command of the brigade commander and were meant to support tank companies with mobile and powerful anti-tank guns

 

87 tank destroyers were ordered from Landsverk. The new design was to be based on the Strv m/42 medium tank, but would feature an open-topped superstructure instead of a turret. The vehicle was to be propelled by a newly developed 410hp engine from Volvo and equipped with a new mechanical gearbox. The front would be 70mm thick and house a high power 75mm gun. The layout was fairly conventional, with transmission at the front, open topped crew compartment in the middle and the engine in the rear. The weight of the vehicle was not to exceed 23 tons. A prototype was finished in winter of 1943 and production was planned for 1944 however problems with the development of the new gearbox as well as a series of strikes in 1945 delayed the delivery of the 87 vehicles untill 1946.

In 1956, along with the refit of the Ikv 72 to Ikv 102 (see previous part), it was decided to start the production of a second batch of Ikv’s with the upgrades considered for the Ikv 72 built in to the design. This vehicle would become known as the Ikv 103 and a total of 81 vehicles of this type were produced between 1956 and 1957, making it the most widely produced assault gun in the Swedish army at that point. Although externally similar to the earlier models, the Ikv 103 featured a number of changes, such as the addition of a roof, a change of the main armament from a 75mm to 105mm and the addition of a more powerful engine. The engine, used in the Ikv 103 was a 150hp 4-cylinder boxer engine, originally developed by Svenska Flygmotor AB for use in the Saab Safir training aircraft. The air for the new engine did not need to pass through the crew compartment (something appreciated by crews in winter) and this also gave the vehicle its distinctive “grills” on both sides of the engine compartment. Generally the vehicle was well liked by its crews, who enjoyed its great maneuverability and high top speed.

The UDES XX 20 was an experimental tank destroyer constructed in the 1980's for the swedish army. By the early 80s the incredible mobility of the Bv 206 with its split chassis configuration had shown the potential for a highly mobile vehicle that would be ideally suited to the heavily forested northern areas of Sweden. It was decided to explore the possibility of creating a tank destroyer with this type of chassis configuration as part of the UDES project. The vehicle would be operated by a 3 man crew placed in the front, the rear contained the engine compartment and the ammunition stowage (on the planned production version). For better observation the vehicle was intended to be fitted with an extendable cupola for the commander. The vehicle was armed with a autoloaded 12 cm L/44 Rheinmetall smootbore gun which was mounted to the front car. Two prototypes were produced and tested extensively however these tests showed serious shortcommings with observation and the time to enter a fire position, the complexity of the split configuration also proved problematic due to lacking reliability. Ultimately it was concluded that despite the promising mobility advantages a conventional vehicle would be preferable.

Rank 4: Lvkv fm/43 (1952)

SEkr6ED.jpg

In 1952 all Lvkv fm/43's were refitted with 290-300hp maybach engines as a cheap solution to the lacking mobility of the vehicle. In addition the turret rear was redesigned to fit the radio, the drivers hatch was swapped for a two pice one and a spacer was introduced between the turret and the hull. In this configuration the Lvkv fm/43 would serve untill 1969 when they were taken out of service without a replacement.

Rank 4: Lvkv 42

LjgiVyV.jpg

A light SPAAG developed in the late 40's by AB Bofors for the Swedish military as a sucessor for the Lvkv fm/43. The vehicle was armed with the new 40 mm L/70 Bofors gun which provided the same rate of fire as the two guns on the Lvkv fm/43 combined and at a higher muzzle velocity. The project was canceled in favor of developing more modern radar equipped SPAAG's, the two vehicles that were built would serve as test rigs for testing and developing the radar systems for the VEAK 40.

Rank 6: VEAK 40

1-0.jpg
The VEAK 40 was a SPAAG developed alongside the Strv 103 which shared its major components. The prototype was completed in 1964 and was armed with dual 40 mm L/70 guns which had a rate of fire of 300 rounds each and were fed from two 70 round magazines. Even though the vehicle had been equipped with a older radar than had initially intended the 1964 trials showed very promising results, despite this the VEAK 40 project was mothballed and eventually canceled due to a lack of funding.

Originally built by AB Landsverk for the Danish military, only a few were delivered before the delivery was stopped. The vehicles were refitted with new turrets and 20mm autocannons and put in service with the swedish army. Another 20 vehicles would later be produced by Volvo, these mainly differed in the choice of enigine. In the period following ww2 all Pbil m/39 and m/40 were sold to the Dominican republic where they served and also saw combat in the Dominican civil war.

The Pbil m/41 was originally intended for the Dutch army but a ban on military exports prevented delivery of the last 5 vehicles. The dutch vehicles were refitted with the same turret and armament as the Pbil m/39 and entered service with the swedish army where they remained in service untill 1956.

Sources
Currently im sitting on around 30 000 pages of material from the Swedish war archives on armor development between the 1920's and 1980's. In addition to this i also have acess to various documents and articles from SPHF (Swedish historical armor association) as well as a number of books on Swedish armor. If there is anything in particular you want a source on ask me and i will see what i can dig up.

 

 

Special thanks
Renhanxue for digging up the vast majority of the information from the Swedish archives and allowing me to post it here.
Yuri Pasholok for his pictures and measurements of various Swedish vehicles.
Joel for looking into Swedish projects from the late 70's including composite armor information.
Blockhaj for finding the pictures of the Strv m/42 "Delat torn".

I'm always for new countries and this seems like a reasonable enough tech tree to be added

Admittedly I'm curious on the handling characteristics on the UDES XX 20

So, a complete (and full) Swedish air and ground tree are possible. This would be good after all the other stuff Gaijin has planned is done (so two years from now). I like it.

First, I totally agree with this tree.
It's a great tree! :salute:

 

but how about a Neutral Tech Tree?

Not only Sweden, but also Finland, Switzerland, Netherlands, Belgium  and Spain.

This could be a good addition of Swedish forces Tech tree.  :D

yeah i think sweden is covered on the naval front. now finding info on the ships that are actually applicable to the current WT timeframe is a different story but there's at least plenty of quantity.

As in the list

https://en.m.wikipedia.org/wiki/HSwMS_Göta_Lejon

This was the biggest ship in service isn't it?

im not exactly a big fan of the idea of mixing a bunch of completely unrelated nations into a tree, thats why i made this tree in the first place. If it really has to happen i would prefer a "scandinavian tree" which would also include finland, but really that tree would be a sweden with friends tree since none of the other scandinavian nations have any domestic tank or plane designs.

It would be good to see a Sweden tree - ships and planes could be possible, including Norway and Denmark for a few BR gap fillers.  The more critical thing is likely that they will likely create trees for the likley player base in new nations so for example Poland apparently has a sizeable tank game playing playerbase. The next trees are likely to revolve around nations they want to market to. It is also a question as to how they want to evolve the sides in RB and other modes - WWII then cold war but also post cold war if plans for modern tanks are as rumoured. All this makes a stand alone tree impossible to predict. However it is a worthwhile project to fill a tree with designs so that it can be made, one day, in some form. Lots of Swedish vehicles could be interesting.

I think the suggestion can be forwarded if there are the data (original docs and not monogaphs or suppositions written on wiki) for each tank.

Just an example, "the speeds and the ratio of the gears?", "how fast is the turret traverse speed?"

T

"There are photos of each part of the vehicle?"

Just 1 photo a sketch of the blueprint and a wiki data is not enought for doing a tank, you have to think like a 3d modeller that must have to build from 0 the vehicle.

Yes i understand that, and i do have that kind of information on most if not all of these vehicles. I dont know if id like to post it all publicly though, Id much prefer getting in contact with somebody at gaijin and giving them that directly. At least thats the way it worked when i was involved with the research for the swedish tech tree for... a tank game that shall not be named.

Whenever I see this I'm always surprised at just how many different armored vehicles Sweden built. While there will be holes in the tech tree and a few of the vehicle placements are questionable (mainly the Ikv 102/103, compared to most of the other Rank 4 TD's their firepower seems pretty lacking) I don't think that would be too much of a problem. As someone who loves rare and obscure vehicles like these, I'll definitely support an independent Swedish tech tree!

 

Also, the Strv m/40L Rb 51 being added would mean that there's finally a worse ATGM than the Type 60, which I find kinda hilarious.

Great work on finding all these vehicles, but I do have a question. I've always heard people say that a turret for the KRV was never built, do you have any images or documents disproving this?

The turret was never constructed beyond a mockup, though an order was placed for the 150mm smoothbore gun barrel (later changed to 145mm rifled) and a 15,2 cm howitzer was converted to 14,5 cm to test the ammunition for said barrel.

Thanks.

Anyway concider that the Ikv 102 and 103 have the same HEAT-FS round as the 105mm L7, which ingame has 400 mm of penetration, this coupled with them being tiny and quick and 20 degrees of gun depression has some trolling potential. Still will get destroyed by pretty much anything larger than rifle calibre MG's but the vehicle is not as bad as it might seem.

I see. It probably won't be included then if Gaijin adds Sweden since it isn't technically required to make a proper tt. A shame really, it's such a cool tank and the other game really butchered it imo.

Yeah. im just hoping i can push for the hull to be added in some way, hopefully as the Strv K (strv 101 turret on KRV hull) which i have listed as a potential premium right now.

Hmm... was expecting a lot of "but the Strv 103 is a tank destroyer" discussions.

Pleasantly surprised that most folks seem to understand that it was a tank, not a tank destroyer.

For those of you who want to follow the progress on the research for the tree more closely (ore just want some more info on vehicles than what is available here) i have created a blog where i will publish various things from the Swedish archives as well as articles on specific vehicles. If you are interested the blog can be found at: https://fromtheswedisharchives.wordpress.com/

Can't stop looking at the Strv 103. :016:

If Italy can have its tree, Swediland should also.

I don't see the KRV in the tree, only the cent mk.10 turret version. 

Yeah Ive not put it in the main tree. Id love to see it and its less of a stretch than some of the vehicles we have ingame right now but i dont want to put it in the main tree since the turret was never completed. Im just hoping we can see the hull in some form , which is why i have the Strv K as a premium. Both its hull and turret were completed and used, so i think its a safer bet.

Eh, that is prob the most iconic tank when I think about Sweden, doesn't really matter if the turret was built or not, it was tested with a testweight so there is enough info to make a model.
