Description
The Combat Vehicle 9030 Finland is a rank VI Swedish light tank with a battle rating of 9.3 (AB/RB/SB). It was introduced in Update "La Royale".
General info
Survivability and armour
The CV9030FIN has 20 mm of frontal hull armor, which is not significant enough to stop anything larger than a 14.5 mm machine gun. But, the upper plate is angled very well and as such could possibly prevent low-penetration auto-cannons from damaging the vehicle; the hull front, with its slope, can offer from 20 mm on the lower glacis up to almost 90 mm of effective thickness on the upper glacis. The side armor is composed of two spaced plates, one 6 mm and one 10 mm plate (for a total of 16 mm). This is enough to stop low-caliber machine guns, but a .50 cal will penetrate the armor with ease. A fuel tank is located between the spaced armor plates of the left side of the hull, right beneath the turret; the fuel tank is able to absorb machine gun bullets, protecting the turret crew from the left side from machine gun fire. The rear of the hull has 20 mm of armor, enough to stop low-caliber machine guns. Shots by large caliber cannons to the turret will more often than not only kill a single crew-member allowing an attacking response or swift retreat.
Armour type:
- Body made entirely of rolled homogeneous armor
- Structural steel boxes attached to sides and rear of turret
- Composite screen covering front, sides of turret, and sides of hull.
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 20 mm Hull plate over tracks
20 mm (78°) Upper glacis 20 mm (30°) Lower glacis - Upper section 20 mm (41°) Lower glacis - Middle section 20 mm (52°) Lower glacis - Lower section |
20 mm (16°) Crew compartment
10 mm Hull plate over left tracks 5 mm Hull plate over right tracks |
10 - 21 mm | 6 mm - 20 mm |
| Turret | 31 - 85 mm Turret front | 60 - 65 mm | 25 mm | 20 mm |
| Cupola | 61 mm | 23 mm | 20 mm | 20 mm |
Notes:
- Suspension wheels, tracks and bogies are 15 mm thick.
- Belly armor and the bottom plate above the tracks are 10 mm thick.
- Mudguards are 5 mm thick
- Inner armor plates protect the sides of the crew compartment (the upper section over the tracks only).
- The engine is separated from the driver position and the crew compartment by an armor plate.
- The driver viewport is a weak spot as it is the only place where the inner armor does not overlap with the external armor

Usage in battles
APFSDS round allows adequate penetration of MBTs from the side and rear angles and is best utilized to position the vehicle to allow such shots. While acceleration is poor the fair top speed allows creative positioning and the good reverse speed provides for the ability to use shoot and scoot tactics. Only IFVs and other lightly armored vehicles can reliably be destroyed from the front.
Pros and cons
Pros:
- Amazing vertical guidance for both main gun and machine gun
- Magazine fed gun instead of single shells like on the CV9040 variants
- Engine block at the front of the vehicle can tank some damage
- APFSDS has decent penetration which allows the tank to penetrate the sides and backs of most tanks
Cons:
- Thermals and APFSDS are Rank III modifications which require some time to get
- .50 cal fire can penetrate the back of the vehicle
- Mediocre acceleration, takes rather long to get to the top speed
- Has only one turret-fixed 7.62 mm machine gun, rendering it useless against targets when the turret is knocked out
History
The development of the CV 90 began in the early 1980s to meet the new requirements of the Swedish army. The force reduction of 10,000 troops and a rearrangement of the army were to be collected by increasing the mechanization of the armed forces. A family of vehicles was requested that would have a high level of strategic and tactical mobility as well as air defense and anti-tank ability with the highest possible survivability. Friendliness of reply and NBC protection were absolutely necessary. The new armored personnel armor conditioners should be able to destroy enemy armored personnel in duel situations.
In 1982, the Swedish Procurement Office Försvarets Materielverk (FMV) defined the catalogue of receivables and analysed the international arms market – with the result that none of the vehicle families offered could fulfil the performance catalogue. This made an in-house development inevitable. The name for the base vehicle was Stridsfordon 90. As many commercial off-the-shelf as possible should be used to reduce costs and save time. Until 1984, the Swedish arms industry built an unarmed test vehicle, which was subjected to extensive testing. In May 1984, a wooden model in its original size followed. At the same time, a test of two British tanks (FV107 Scimitar and Stormer) ran as crew transporters. This last attempt by the FMV to find an alternative on the arms market failed and led to the contract allocation of 200 million Swedish crowns in 1985. H-B Utveckling, a joint venture between AB Hägglunds & Söner and Bofors AB (since 2003/2005 BAE Systems), was responsible for chassis and a 40 mm machine gun. Prototype production began in 1986.
The first prototype was handed over to the Swedish armed forces in October 1988. He had a 40 mm Bofors gun type 40/70B. The remaining four examples followed until the beginning of 1989, the fifth vehicle was the tank Prototype 2 received a different armament with McDonnell Douglas' 25 mm M242 Bushmaster machine gun. The drive was used by Scania engines and automatic transmissions from Volvo, with a vehicle equipped with the X-300-5 transmission from Detroit Diesel Allison Division. Hydraulic, electrical and mechanical systems were tested as tower drive types. The subsequent troop testing lasted until 1990 and was carried out under different climatic conditions. In total, the prototypes covered around 50,000 km. [1]
