The UDES 03 is a Swedish tier 8 tank destroyer.
Developed in the early 1970s by the UDES research group, Bofors and Hägglunds companies. In 1972, the project was provided by the Bofors company. Later, it was decided to return to the concept with a traversable turret, and development was continued within the UDES 14 project. The Bofors project remained only in blueprints.
The UDES 03 is the first of the Swedish tank destroyers that features hydraulic suspension, where one can switch between two modes -- Travel Mode, which offers great mobility but sacrifices gun handling, and Siege Mode, that offers great gun handling in exchange for mobility.
The UDES was nicknamed "Mountain Goat" for its ability to climb over rough hills and some hard terrain that is normally rarely accessible with other tanks. Some might use its advantage by sniping on high hills (hills on the northern side of the Redshire map for example) that provide great terrain protection and a sniping spot for this vehicle.
Unfortunately the UDES is fairly hard to maneuver. Its heavily sloped armor can easily be over-matched by 61mm+ caliber guns. Combined with its absolutely horrible mobility in siege mode this won't help you deal with flankers and also makes the UDES a priority target for SPG's.
To shine in the UDES 03 players must know when and where they will position. Use your great mobility in travel mode to relocate yourself from enemies when you feel unsafe and use your great gun handling in siege mode to destroy enemy tanks.
The UDES 03 leads to the Strv 103-0.

Player Opinion
Pros and Cons
Pros:
- Great gun handling (while in Siege Mode), loses only about 10mm of penetration even at 500m range
- Amazing gun elevation and depression in Siege Mode
- Upgraded gun has highest penetration standard rounds at Tier VIII (even at Tier IX) and 1450m/s shell velocity, making it easy to hit targets at long range
- The tank can stand up on its tracks, thanks to the gun elevation and hull depression, allowing shooting over small walls and other hard cover (see 'Performance' below on how to do this)
- Best camouflage value in Tier V+ -- can reach up to 70% while stationary, and great camouflage when moving (can reach to more than 30%, which is even better than some Tier VIII light tanks)
- Very high top forward and reversing speeds, great power to weight ratio and maneuverability in Travel Mode
- Low terrain resistances combined with great mobility allow this vehicle to climb some rough terrain (including some areas that cannot be accessed with other vehicles) with ease
- Tank can turn in place without resetting a binocular telescope or camouflage net
Cons:
- Prone to engine damage with hits to the front-mounted engine, which leads to frequent fires and lengthens transition time in and out of Siege Mode
- Rotates much more slowly when in Siege Mode than the Strv S1 (due to the traverse speed while not moving)
- It has the second-lowest HP pool for non-SPG vehicles in the same tier (1000) and is very vulnerable against high-caliber guns and SPG's, especially in Siege Mode
- Mobility in Siege Mode is terrible -- 5km/h both forwards and backwards -- and makes it very vulnerable in close range combat
- Nearly always penetrated because of the over-match (HE doesn't apply so arty can't over-match) rules (>61mm) comparing to the premium Strv S1 (>120mm) -- that's (all but some 57mms found on Light Tanks) the Tier VI to X guns! Highly vulnerable to HE rounds
- Lack of gun depression in Travel Mode
- Mediocre aiming time (three seconds) when outside Siege Mode
- Low ammo capacity (48 rounds for stock gun; 40 rounds for top gun)
- No horizontal gun arc makes it hard to hit mobile targets (because it must move all the time and loses accuracy); can't shoot mobile targets if tracks get destroyed
- Despite having high nominal penetration your shots will bounce a lot when shooting (sometimes even slightly) angled armor at Tiers VIII-X due to APCR rounds having lower normalization than AP. Shoot flat sections whenever possible or you will get frustrated at times
- Low hull traverse rate at stock
Performance
This tank, along with the 103-0 and 103B, are the main true sniper tanks. Use Travel Mode to get to a good spot and set up Siege in a bush. As long as you don't get spotted, dealing 3-5k damage in a game is easy (as top tier).
Tip to use low cover effectively: Hide behind cover, activate siege, aim low (that raises your butt) and then straight. That raises your gun above cover so that you can fire. Undo Siege to lower your whole tank to get back under cover. Repeat.
Early Research
- Tracks: The basic chassis allows you to install the "top" gun, but it will have to be delayed with the installation of a new engine and improved radio due to the increase in the mass of new modules
- The gun: The "top" gun 10,5cm kan UDES 03 has excellent penetration with a base projectile of 288mm, a nice damage per shot of 390 and slightly lower DPM compared to the 9cm kan m/F
- The engine: The "top" engine will give 50 h.p. and decrease the chance of a fire by 2%, however it will slightly increase the weight of the machine itself, which is critical when using the "stock" tracks
- Radio: The Ra 400 "walk-through" radio will give 710 meters of communication range. The Ra 450 radio gives 850 meters range.

Historical Info
In the early 70s, the Swedish army was granted 1,8 million kronor (8 million USD) for the development of a light AFV family during the 1971-1975 period. As part of this project, the army set up a number of research groups. The most important of these were UDES, which was based at the Defense Materiel Administration (FMV), and headed by Sven Berge (the engineer behind the S-tank concept).
The role of UDES was to gather, process and coordinate information regarding armored fighting vehicles. Which would serve as a technological-economical overview in that field. In practice the UDES group would develop and catalogue different conceptual alternatives for new Tanks, TD’s and APC’s. The funding behind the project was only half of what the army deemed necessary. Because of this FMV decided to outsource parts of the development to Bofors and Hägglunds, which were experienced with AFV development.
HISTORY AND DEVELOPMENT
Initial studies focused on the development of a cheap tank in the 20 ton range that would be able to use interchangeable parts in the planned light vehicle family. To keep costs down, a large extent of the components used had to be existing and commercially available. A power to weight ratio of 30hp/t and a crew of two (later three) men was also a major requirement. Later on, these requirements would lead to three different lines of development including Turretless, Conventional and Remote turret vehicles.
OBJEKT 2013 A
The first of these to be examined was a light turretless vehicle that had already been in development since 1970 under the name Objekt 2013 A. The vehicle was essentially a miniaturized Strv 103 but with one major difference, a gun capable of elevating and depressing independently of the hull. Its main advantage over a fixed gun design was easier movement in terrain and that it was possible to stabilize the main gun. The Vehicle was re-designated UDES 03 as per the naming conventions of the UDES research group.
PBV 302 BASED TEST RIG
To test the concept, a wood mock up was fitted to the side of a Pbv 302 APC in early 1971. During the tests it was uncovered that the gun would block the field of view when elevated along with other potential problems. Still the results proved that the concept was viable and a order was made for two test rigs. Bofors would handle the construction and testing of a “shooting rig” for testing the main armament, and Hägglunds would do the same for a mobility test rig.
SHOOTING RIG
In 1973, both test rigs were finished and readied for testing. These prototypes made use of parts from the Pbv 302, such as the tracks and roadwheels although they were later refitted with more durable roadwheels. The shooting rig was externally powered by a electric powerplant and was armed with a cut down 105mm gun for testing. The tests found several faults with the design. The vehicle would regularly throw its tracks when aiming and tracking a target was almost impossible unless on hard terrain due to faults with the suspension.
MOBILITY RIG
Comparatively the mobility rig was a more complete vehicle. Unlike the other test rig it was powered by a internal diesel engine. One of its stranger design elements was the exhaust which vented underneath the vehicle which was done to reduce the infrared signature. This 12 ton vehicle was used to test the terrain passability under different conditions.
BOFORS PROPOSALS
Based on the requirements set by UDES and data gained from the trials Bofors and Hägglunds, a number of proposals for both alternative developments and improvements to the vehicles were submitted.
HÄGGLUNDS PROPOSALS
In may 1973, during one of the UDES group meetings it was suggested that a turreted alternative to the UDES 03 should be considered. The turreted design would have to be in the same price and weight range as the UDES 03 and use the same main armament. This turreted light tank would be called UDES 14. This would a shift focus away from the UDES 03 and its development was largely discontinued after 1973 in favor of turreted and later remote turret alternatives.
LEGACY Although the development of the UDES 03 was discontinued the experience gained from its test rigs would be used in the development of the CV90 armored fighting vehicle and the Strv 2000 project. The fate of the shooting rig is unknown, however the mobility test rig was last seen in the 1990s rotting away at a military scrapyard.

Historical Accuracy Errata
The UDES 03 project was developed after the Strv 103 entered mass production, And it was meant to developed as possible replacement for Strv 103. However, in World of Tanks, this vehicle was placed as predecessor to Strv 103 project.
