BAE Systems launches lighter, cost-effective tank alternative
The Swedish division of BAE Systems has unveiled an updated concept for a light tank, derived from the chassis of the CV90 infantry fighting vehicle (IFV). This presents an economical alternative to the Leopard 2 tank.
The CV90120 is a variant of the renowned Swedish CV90. Initially fitted with a 105 mm cannon, the turret has been upgraded to accommodate a 120 mm tank gun. This innovation results in a fire support vehicle possessing the firepower of a tank while being significantly lighter.
Sometimes a cannon is the only solution
There are situations where nothing can replace the impact of high-explosive or kinetic penetrator shells. For instance, in Ukraine, tanks are frequently employed as artillery support. Additionally, increasingly common active protection systems can intercept traditional anti-tank guided missiles. Although there remains a challenge in countering those that descend on tanks from above, systems to address this will eventually be developed.
In contrast, only robust multilayer front armor can defend against kinetic penetrators made from tungsten or depleted uranium. Weighing several pounds and traveling at speeds over 4,900 ft/s, these penetrators can exert kinetic energy reaching up to 10 MJ, comparable to the long gun of the Leopard 2A6 tank or later models.
The cost factor is also significant, as a single penetrator shell costs far less than a FGM-148 Javelin or an Akeron MP missile, both of which can be priced at several hundred thousand dollars each.
CV90120 - Enormous firepower in a familiar format
The strength of the CV90120 stems from its maximum utilization of the CV90 IFV's systems and chassis. This shared platform weighs around 88,000 lbs, simplifying logistics and training. As shown in Ukraine, heavy tanks like the Challenger 2 or M1A1 Abrams struggle in muddy terrains, whereas lighter platforms like the Leopard 1A5 can be highly effective with adequate protection against anti-tank missiles and drones.
The CV90120 accommodates a crew of three, with the possibility of adding two more personnel for roles like reconnaissance drone operations or unit coordination. This is crucial because the vehicle's effectiveness and survivability depend more on tactical deployment than on armor protection.
The armor is expected to remain consistent with the standard CV90, providing resistance against automatic cannon fire but not against tank shells. Adding an active protection system is key, as it can intercept anti-tank missiles or grenades, the primary weapons of infantry units and many vehicles.
The principal threats are enemy tanks or other fire support vehicles with large-caliber guns. However, these threats can be effectively countered with the CV90120's own 120 mm gun, featuring a barrel length of 47–55 calibers. The gun is equipped with an autoloader, enabling a rate of fire of 12–14 rounds per minute. The ammunition magazine holds 16 rounds in the autoloader, with more than double that quantity stored in the hull.
It's noteworthy that Slovakia has expressed interest in purchasing a batch of these vehicles. As of January 2025, there is speculation that Slovakia may opt out of acquiring 104 Leopard 2A8 tanks in favor of choosing the more affordable Swedish alternative. This option offers comparable firepower and complements the CV90 IFVs already selected for its military forces.
