Up until the early 1980’s, the SADF anti-air regiments were reliant on towed equipment. However, as the military doctrine shifted towards mobile warfare, the need for a self-propelled anti-air gun unit became clear. As a result, South African engineers began working on a respective design, which had to be rugged enough to withstand the harsh South African terrain and threat of landmines, yet light enough to ensure a high level of mobility.

Description

The Ystervark is a rank British SPAA with a battle rating of (AB), (RB), and (SB). It was introduced in Update "Ground Breaking".

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.

Armour type:

Armour Front (Slope angle) Sides Rear Roof
Hull ___ mm ___ mm Top
___ mm Bottom 		___ mm ___ - ___ mm
Turret ___ - ___ mm Turret front
___ mm Gun mantlet 		___ - ___ mm ___ - ___ mm ___ - ___ mm
Cupola ___ mm ___ mm ___ mm ___ mm

Note:

  • Ammunition is divided into 8 magazines of 75 rounds.

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:

  • Fast 900+ rounds/min firerate allows it easily score hits with a burst on an aircraft's flight path
  • Small profile makes it very easy to conceal itself
  • High top speed of 90 km/h means great agility
  • Lack of armour means conventional cannons will struggle to one-shot it if poorly aimed
  • 75-round belt allows it to confidentally engage targets without worrying too much about reloading

Cons:

  • The driving compartment can obstruct the autocannon's gun depression which might be sometimes fatal
  • No armour protection, making it highly vulnerable to MG bullets, shrapnel, and even ramming from tanks and aircraft
  • Is wheeled, meaning its mobility will be significantly worsened on bad road conditions
  • Reverse speed of -13 km/h can be inadequate, especially when comparing to its counterpart R3 T20
  • Gunsight is position far above the gun, which can be awkward to aim in simulator
  • Complex appearance can make it hard to place bushes, decorators, and decals

History

Up until the early 1980s, the SADF anti-air regiments were reliant on towed equipment. However, as the military doctrine shifted towards mobile warfare, the need for a self-propelled anti-air gun unit became clear. As a result, South African engineers began working on a respective design, which had to be rugged enough to withstand the harsh South African terrain and threat of landmines, yet light enough to ensure a high level of mobility.

Building on the basis of a previous mine-resistant vehicle project, the engineers came up with a light SPAAG design, built on top of the Bulldog APC chassis between 1983 and 1984. Entering service almost immediately, the Ystervark was used to accompany South African mechanized battalions and to protect strategic assets, such as air bases in the southwest African region. Ystervarks were first employed operationally during Operation Thunder Chariot in 1984 - a division -scale exercise in South Africa during which the Ystervarks were first tested.

However, the Ystervarks didn’t have to wait long for their first combat deployment. Taking part in several operations in the ongoing South African Border War from 1986, Ystervarks were used to great success as deterrents to low-flying Angolan attack aircraft and helicopters, even downing several Angolan MiGs in 1986 and 1987.  After the conclusion of the Border War in 1989, the Ystervark was gradually being phased out of service in 1991 and replaced by the SAMIL 100 Kwêvoël mine-protected SPAAG armoured truck called the Bosvark. Officially, the Ystervark was withdrawn from active service in 1997 after more than 70 units were produced.
