Description

GarageImage Strv 74.jpg


The Stridsvagn 74 is a rank IV Swedish medium tank with a battle rating of 5.7 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".

A modification of the older Strv m/42, the Stridsvagn 74 has acquired a more powerful 75 mm cannon with the ability to fire an APDS shell but has relatively weak armour compared to similar BR vehicles.

General info

Survivability and armour

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Machine guns

Main article: ksp m/36 (8 mm)

The Strv 74 has a pair of 8 mm ksp m/36 machine guns, one mounted coaxially and the other mounted upon the commander's cupola. The machine guns have very low penetration and mass making it harder to use than some of its counterparts. They are best used deterring aircraft as your lightly armoured top is often the target of aircraft with heavy armament. The roof armament is immediately unusable if the commander has been killed or forced to take on the gunner or driver's position.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

  • Incredible gun depression of -15°
  • APDS round has 248 mm of penetration at 500 meters
  • Starts stock with the effective APCBC round found on the Pvkv II
  • Quick gun elevation and depression

Cons:

  • Turret is a massive target
  • APDS shell is a Tier IV modification
  • Outdated chassis - narrow tracks and thin armour
  • Slow reverse of -4 km/h
  • Reduced mobility due to increased weight
  • Commanders machine gun reduces visibility to the right in Simulator battles
  • APHE has difficulty knocking out big heavy tanks with spaced out crew

History

Development

After the end of World War 2, the only medium tank Sweden had was the Strv m/42. This vehicle was no longer capable, and had become obsolete. The Swedish military considered buying French AMX-13's, but decided to instead buy the British Centurion. Sweden had a need for a light tank still, and decided that designing a new light tank would take too long and be too expensive, so instead they decided to create a new light tank with the chassis of the Strv m/42. The Strv m/42 had been retired in 1950, and in 1953 the process of upgrading the tanks was started. First, putting the turret of the AMX-13 on the Strv m/42 chassis was considered. This would be impossible, because the turret rings had different sizes. Instead, a new turret was designed. It was armed with a 7,5 cm Ivkan m/36 anti-aircraft gun modified for use in a tank. The Swedish military supported this design because it would be cheaper than buying a foreign tank, and ordered two prototypes in 1954. The Strv m/42 EH was not chosen to hold the new turret, as its engine was unreliable, but the Strv m/42 TH and TV were chosen to house the new turret.

Design

The turret had a unique shape, it was heavily sloped on all sides, but the armor was at most only 20 mm thick. The armor was kept to a minimum as the suspension would not be able to handle more weight. It shared many components with the Centurion. The back of the turret contained a Volkswagen engine used for heating and insulation. The gun could depress to an impressive -15 degrees. The chassis had to be modified in order to handle the increased weight of the new turret. The shock absorbers were replaced, the steering mechanism was changed, the driver's hatch was changed, and the tracks were widened to decrease ground pressure. The twin engines of the Strv m/42 TH and TV were replaced by Scania-Vabis 607 engines. These increased the horsepower, and they increased reliability at low temperatures. Smoke dischargers, a spare road wheel, and a bustle rack were added to the turret. The vehicle carried a crew of 4 men.

Production and Service

225 Strv m/74 were ordered by the Swedish military, and the order was spread between Hägglunds & Söner and Landsverk. There were two variants, the Strv m/74 H (based on the Strv m/42 TH) and the Strv m/74 V (based on the Strv m/42 TV. The only major differences between the two was the gearbox. The Strv 74 was designated as a light tank until the 1960's, when it was re-designated as an infantry support vehicle. When the Ikv 91 entered service, the numbers of Strv 74 decreased as the Ikv 91 could do everything better than the Strv 74. The Strv 74 was fully retired from service by 1984, and some of the turrets were used as static fortifications until the late 1990's.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
