The Strf 9040 is the designation of the Swedish Armies Stridsfordon 90 (Swedish for Combat Vehicle 90). The 40 refers to the 40mm Bofors auto-cannon main gun. Over 50o vehicles in different models and variants have been built for the Swedish Army.

Since entering production in 1993 for the Swedish Army, the Strf 9040 design has been improved with a number of upgrades.

The Strf 9040C is the most heavily armored version in Swedish Army service and in 2016 the Government awarded BAE Systems Hägglunds AB And BAE Systems Bofors AB, a contract to refurbish and upgrade 262 Strf 9040 for the Army.

The Strf 9040 (refered to in Sweden as the Mk 0) has also evolved into several export models and the most advanced medium tank available to date. Known commonly as the Combat Vehicle 90 or CV90, it is the most successful Tracked Infantry Fighting Vehicle in Europe and the NATO Alliance. This page focuses on the Strf 9040 in service with the Swedish Army.


In 1983 the Swedish Defence Material Administration (FMV), along with the Swedish defence industry formed the Combat Vehicle 90 Project for a new tracked Combat Vehicle for the 1990’s. In 1985 development of a chassis and 40 mm gun started with, the first prototypes ordered in 1986.

In total x5 hulls and different turrets were built at the same time, with all 5 hulls having distinct ID numbers painted on the hull front, lower glacis, left side. The most common photographed were 204797, 204798 and 204799. These were delivered in 1988 for army trials.

Each prototype hull and turret varied, for example 204799 had a raised dome in its engine bay hatch. Some turrets Machine Guns were positioned differently or had additional sights.

During the development and trial process, the Strf 90 was installed with both a 25mm (Strf 9025 aka CV9025) and 40mm auto-cannons (Strf 9040 aka CV9040). Following extensive trials, the FMV selected the 40mm Bofors cannon and the 25mm M242 Bushmaster cannon was dropped.

In 1990, Epbv 90 and 90 Stripbv variant turrets were ordered for trials and photographed on 204797, 204798 and 204799.

In 1991 series 1 production was ordered, followed by the series 2 order in 1993. This was for the Epbv 90, Lvkv 90, Stripbv 90 and 90 Bgbv variants.

Serial production started in 1993 with AB Hägglund. In October 1997 the British company Alvis plc acquired Hägglunds Vehicle AB to form Alvis Hägglunds AB and through a number of other company mergers to form BAE Systems AB.

The Strf 9040 has a conventional Infantry Fighting Vehicle layout. The engine bay is located at the front, on the right side, with the drivers compartment on the left. The 2 man turret is located in the middle, with the troop compartment in the rear.

They exit the vehicle through a large rear door using the vehicle as added protection as they dismount. additional hatches are mounted in the roof, which can be used by the infantry to fire their personnel weapons when opened.

Strf 9040 40mm Bofors Cannon

The Strf 9040 uses the Bofors 40mm L/70 version cannon. It fires x3 principal rounds: Bofors 40mm APFSDS-T, HE-T and Bofors 40mm 3P “Prefragmented Programmable Proximity-Fused” HE-T (as well as 40mm TPDS-T Practise Round).

The 40mm cannon is fed by a carousel at the bottom of the turret. The carousel is then refilled from a storage bin under the turret by the infantry in the back.


Strf 9040 Armor
Strf 9040 Armor – Red is frontal armour rated against 30mm AP rounds, Blue rated against 14.5mm rounds.

The Basic Strf 9040, 9040A and 9040B are rated to protect against 14.5mm AP rounds on all sides/rear of the vehicle. The Frontal arc (Red) is rated against 30mm rounds. However, a colleague who is ex-Swedish Gunnery Instructor states that the frontal arc can withstand 40mm AP rounds fired by the Bofors 40mm main gun.

The vehicle is fitted with full NBC protection. The engine is located in the front of the vehicle, which acts as additional protection for the crew located behind it.

The vehicle is fitted with a bank of smoke grenade launchers on either side of the turret capable of firing smoke and other visual obscuring grenades.

Overall protection can be uprated with add-on modular armour when deployed in conflict zones.
