STRV 2000

The never realized supertank

Hit Counter

In the late eighties it became apparent that Strv 101R, 102R, 103C and Strv 104 were inadequate against the evolving threat. To prepare for purchase of foreign tanks an M1A1 and a Leopard 2 were borrowed for a year to help formulate technical specifications for a new tank. A swedish concept was studied as well. It was influenced by the experiences with the "S" and the lessons learned from the trials with the UDES 03, UDES 19 and the UDES-XX-20 in the late seventies and early eighties.


The UDES 03 was a test vehicle were the concept of an elevating gun mounted on a turretless chassie was tested and found workable. The UDES 19 was a german Marder with a 10,5 cm gun was mounted on top of the vehicle to test the feasability of a external tank gun in a low profile top mounted turret.


The UDES-XX-20 was ready for testing in 1981. It was based on the Hägglunds BV 206 and had double waiststeering and an external 12 cm tank gun. While mobility was very good the concept is more expensive than tracksteering. The vehicle weighed 25 tons.

The two concepts described below. They are not to scale.

The earlier experiences led to two different concepts for further study. The first with an external gun mounted on an almost invisible turret and the second with a compact turret. The second concept was chosen for further study and a full scale wooden mock up was constructed. The tank was to weigh 55 tons and have modular armor for easy upgrading, a front mounted engine, a 14 cm smoothbore autoloaded gun firing APFSDS only. For softer targets than tanks the coaxial 40 mm autocannon firing APFSDS and HE was to be used, or the 7,62 mm coaxial Ksp m/39. The gunner and commander was to sit on the right side of the turret. The tank  was of course to have a state of the art C3I-system. The importance of IRV had not been recognized when the study started so instead of an adequate IRV the Lyran illumination round mortars were to used. But the studies had clearly shown that the cost for developing a swedish tank was prohibitive compared to foreign purchase. In 1991 the decision to buy a forign design was taken.

The Strv 2000 was a tankers wet dream. With firepower that isnt matched even ten years later and a level of protection that not even the Strv 122 can compete with it would have been the totally dominant titan of any battlefield. Sadly but naturally its cost was equally impressive. The possibility to export it was slim as most potential customers had already bought the Leopard 2. One must also consider the unavoidable delays and cost increases the design inevitably would have suffered from. But what a mashine!

In 1989-1990 an M1A1 and a Leopard 2 had been borrowed for testing to help setup a technical specification as to howa new tank should be able to perform. Two years later foreign bidders entered their designs. The contestants were the M1A2, Leopard 2S and the Leclerc. The british Challenger II was not entered since the british put priority to run the Challenger through desert tests.

The M1A2

The Leclerc

The Leopard 2S

After a year of extensive testing the Leopard 2S was selected. It was found that some further modification was desirable and the final procuct, Strv 122, is probably the best tank in the world. As you can see from the picture below it is clearly better protected than the original Leopard 2S that in itself had outstanding protection.


... and the winner is: STRV 122!
