PUMA IFV - inaccurate gun.

[Adamok2 756]

# Game version

My game version: (2.19.0.85)

 

# Description

Accuracy on PUMA (Mk 30-2 ABM) is terrible in game, but irl rate of fire has been reduced from 700 RPM to 200 RPM to achieve greater accuracy. That accurate is 0.3mrad which is 30cm/1000m.

 

# Steps to reproduce the issue

1. Launch any ground battle (mode doesn't matter)

2. Start shooting with main gun (at 1000m would be best, because 0.3mrad i 30cm/1000m).

3. Look how terrible inaccurate is that cannon (imho sometimes it's over 1m from aiming point)

 

# Additional Information

All information in "# Sources"

 

# Affected vehicles

• PUMA IFV (Schutzenpanzer PUMA) - Germany

 

# Files

No need. Unfortunately there is no shooting range in game (nor on war thunder live) with targets like big, white walls or something to see the accuracy.

On the left side we can read about PMC287 its muzzle velocity, penetrator denstiy, L/D ratio and penetration and dispersion, the most imporant fragment is that about dispersion : "Average dispersion is put at "better than 0.5mils", 0.3 mils having been demonstrated in trials."

3'rd column:

as we can see the text says: "The scatter rate at 1000m doest not exceed 0.5 mrad".

Czech trials in Libava in June 2017 where we can read the PUMA scored 37/40 hits, when the 2'nd best score was 19/40 (no info which IFV was that) at 700m in move, 1200m and 1800m in stay.

 

The most important fragment is (translated to english by google translator):

" In the summer of 2017, the Ministry of Defense invited four manufacturers who responded to the call to trials in the Libavá military area. Manufacturers of types ASCOD (American arms company General Dynamics), CV90 (BAE Systems), Puma (German consortium PSM) and Lynx (German company Rheinmetall) participated.

Four manufacturers with five types (the CV90 arrived in two variants) met at Libavé in June 2017. The vehicles were tested during static, dynamic and shooting tests. Static ones focused on collecting data on weight, dimensions, ergonomics, passive, dynamic and active protection, optics and armament. 

The dynamic tests consisted of driving on a test track and specifying the variables that are associated with mobility. That is, maximum speeds on paved and unpaved surfaces, the ability to climb vertical and horizontal slopes, overcoming deep and high obstacles. Firings were conducted during the third phase of the tests. Both from a place and while moving. 

It fired at a moving target at a distance of 700 meters, but also at fixed targets at distances of 1,200 and 1,800 meters. Some candidates were surprised that it was being tested at such short distances, modern BVP are capable of firing at a much greater distance. Each of the BVPs tested fired five shots at each target in a burst. Since there were eight targets, a total of forty shots were fired.

On the day when the tests took place, the weather in Libavá was not exactly ideal. A strong wind was blowing, which successfully simulated the demanding combat conditions that the individual types had to cope with when firing. The winner of the shooting tests was the German Puma combat vehicle, which was the only one to hit all eight targets, most of them with all five shots. Puma scored thirty-seven hits out of forty shots fired. 

All other contenders had at least one target that they did not hit at all. An interesting fact is that the second best vehicle had only nineteen hits out of forty shots fired during shooting tests. All vehicles passed dynamic tests, but some had major technical difficulties and had to repeat some tests. Although the army did not issue an official communique, military experts mostly agreed in the media that the Puma infantry fighting vehicle from the German Bundeswehr, which also has the added advantage of a high level of ballistic protection, demonstrated unequivocal supremacy at Libavé."
