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.

Some ships are fitted with weapons of various calibres. Secondary armaments are defined as weapons chosen with the control Select secondary weapon. Evaluate the secondary armaments and give advice on how to use them. Describe the ammunition available for the secondary armament. Provide recommendations on how to use them and which ammunition to choose. Remember that any anti-air armament, even heavy calibre weapons, belong in the next section.

Usage in battles

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

Original, the DDR (GDR) wanted to create its own "frigate" and build it in East Germany. In September 1952 Schiffsbautechnik in Wolgast began the development of "Projekt 10 Falke" (Hawk). However, the Project was canceled in 1955 in favour for Sowjet imports. From 1956 until 1959, the Volksmarine received four ships of the Riga-class (Project 50), that where taken from the Baltic Fleet. Some problems emerged at the beginning of the training, simple because many signs were still in Russian and not in German.

On January 16th In 1961 the ships were given the names: Karl Marx, Ernst Thäleman, Friedrich Engels and Karl Liebknecht.

They were intended to combat sea and air targets, to hunt submarines, to provide escort, but also to support landing operations. In 1965/66 they conducted reconnaissance missions off the Norwegian coast and in the English Channel. The Karl Marx became particularly famous for her storm voyage in October 1967, as she survived one of the strongest hurricanes in the Baltic Sea since 1801, only slightly damaged thanks to the masterful efforts of the crew.

The ships were decommissioned from 1968 to 1977. Their successor was the Koni class (Project 1159).

Trivia

Strictly speaking, the East German Navy never had frigates. The term was rarely used in the Volksmarine. Instead, In allusion to the Russian classification, it was classified as "Küstenschutzschiff", short KSS, wich can be translated to "Coastal protection ship".

Media

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