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.

annoS21_UDES_03.png

2620000

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 leads to the Strv 103-0.

Player Opinion

Pros and Cons

Pros:

- Great gun handling (while in Siege mode).

- Amazing gun elevation and depression in siege mode.

- Best camouflage value in tier 5+, 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 8 light tanks).

- Upgraded gun has highest penetration standard rounds at tier 8 (even at tier 9) and 1450 m/s shell velocity, making it easy to hit targets at long range.

- Very high top forward and reversing speeds, great power to weight ratio and maneuverability in Travel mode.


Cons:

- It has the second lowest HP pool for Non-SPGs vehicles in the same tier (1000), and is very vulnerable against High caliber guns and SPGs, especially in Siege mode.

- Mobility in Siege Mode is terrible (5 km/h both forwards and backwards), and makes you very vulnerable in close range combat.

- Overall armor is very poor, will always be penetrated by 61mm+ calibre guns because of the overmatch rules. Highly vulnerable to HE rounds.

- Lack of gun depression in Traveling mode.

- Mediocre aiming time (3 seconds) when outside Siege mode.

- Low maximum ammo capacity (48 rounds for stock gun and 40 rounds for top gun).

- No horizontal gun arc basically makes you hardly to hit mobile targets (Because you must move yourself all time and lose accuracy) can't shoot mobile targets if your tracks get destroyed.


Performance

This tank, along with the 103-0 and 103b, are the main true sniper tanks at this tier. 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.

Historical Info

BACKGROUND

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

Objekt_2013A_blueprints.jpg

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

PBV_302_Based_Test_Rig.jpg

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

UDES_Shooting_Rig.jpg

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

UDES_Mobility_Rig.jpg

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

Bofors_UDES_proposals.jpg

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

Hagglunds_proposals_UDES.jpg

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.
