== Description ==
<!-- ''In the first part of the description, cover the history of the ship's creation and military application. In the second part, tell the reader about using this ship in the game. Add a screenshot: if a beginner player has a hard time remembering vehicles by name, a picture will help them identify the ship in question.'' -->
The '''{{Specs|name}}''' is a squadron rank {{Specs|rank}} German frigate {{Battle-rating}}. It was introduced in [[Update "Wind of Change"]].

The Karl Marx is a squadron vehicle equivalent of the [[Yenot]].

=== Survivability and armour ===
{{Specs-Fleet-Armour}}
<!-- ''Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.'' -->

== Usage in battles ==
<!-- ''Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).'' -->
Compared to other frigates, the Karl Marx has better firepower than most with the exception of late Japanese and British frigates. The biggest downside this ship faces is the reload time. Most frigates such as SKRs and the Köln-class will outgun the Karl Marx. 

The Karl Marx is best played at a range farther than most frigates. This will give the ship better time to respond to threats and keep it away from heavy enemy fire, almost like a mini-destroyer. Like many frigates, focus on small targets such as boats, then frigates, then destroyers. Do not rely heavily on AA as much as other ships such as the Köln as it traverses terribly and has no HE-VT shells. Instead, use any HE-VT or time-fused shells in advance.

=== Pros and cons ===
<!-- ''Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".'' -->

'''Pros:'''

* Has access to radar
* Great firepower
* Has access to HE-VT shells on main armament

'''Cons:'''

* No autoloader (stuck with base 5.2 second reload)
* Horrendous traverse speed on dual 37 mm AA
* Outclassed by other frigates at its BR

== History ==
<!-- ''Describe the history of the creation and combat usage of the ship 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 ship and adding a block "/History" (example: <nowiki>https://wiki.warthunder.com/(Ship-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under <code><nowiki>=== In-game description ===</nowiki></code>, also if applicable).'' -->
