StuH42 (105 mm)

Description

Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.

Vehicles equipped with this weapon

• StuH 42 G

General info

The StuH 42 is a very capable cannon, and is able to take out most tanks at its rank with the Gr.39 rot HI/C HEAT round, which offers 115 mm of penetration at all distances. Post-penetration damage is effective, however, the shells travel at a low velocity. This makes shooting at moving targets and from long distances harder.

Available ammunition

• PzGr - APHE - This is the main ammo type, use it whenever it has enough power to penetrate the target, as the explosive filler can make short work of a tank interior.
• FHGr - HE - Another very useful kind of ammo, can obliterate any unarmoured SPAA vehicles or lightly armoured tanks.
• Gr.39 rot HI/B - HEAT - This one should be just skipped, it has no advantages over the better Gr.39 rot HI/C.
• Gr.39 rot HI/C - HEAT - This shell has the highest penetration, but it is prone to detonate prematurely on spaced armour, or some debris in the flight trajectory. Also, the shell travels at a low velocity, making aiming harder. The advantage is that it bounces less from sloped armour, and the high amount of explosive mass in the round will usually knock out an enemy tank. Lastly, they don't lose any penetration over distance - carry only few of them in case they are needed.

Comparison with analogues

Usage in battles

The StuH42 (105 mm) is best used at medium range combat. The long reload of 13 seconds makes it unviable for close combat, as most enemies at this rank can reload and fire off another shot whilst you are reloading. The Gr.39 rot HI/C shell, which is a HEAT round, doesn't lose penetration over long distances, making it suitable for ranged combat.

Pros and cons

Pros:

• HEAT shells have excellent penetration - 115 mm at all ranges
• HEAT shell doesn't lose penetration over long distances
• Has a variety of ammunition to use
• APHE has good post-penetration damage

Cons:

• Very long reload time - 13 seconds
• Very low velocity of about 500 m/s, makes shooting at moving targets harder
• Shells are inaccurate due to the low shell velocity and the high shell drop

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

Media

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