Supertest: Pan-European Tier IV Destroyer Klas Horn
4 min readThe Klas Horn-class was a pair of destroyers from the Swedish Navy. HSwMS Klas Horn and HSwMS Klas Uggla were both involved in the Hårsfjärden disaster in 1941, leading to the decommissioning of Klas Uggla. Klas Horn was however fully repaired and served until 1958.
So… before we actually look at the stats, I will let something sink in your minds. The Klas Horn, once fully upgraded, has LESS HP than the Tátra (yes, the Tier II). Are you already hyped?
Currently, the concept of European destroyers brings the following features:
- Very fast torpedoes with relatively low damage and long-range;
- Artillery is similar to that of American destroyers: quite effective in close combat but weaker than that of artillery-focused destroyers;
- The speed of the new destroyers is relatively low: 35 knots at Tiers VII — X. It can be increased by an Engine Boost consumable found in a dedicated slot, giving a standard bonus of 8%;
- Starting from Tier VII, the AA defense of European destroyers has a large area of effect and deals good damage;
- Presence of Repair Party: at Tiers V — VIII it is the same as on British destroyers, and at Tiers IX and X this consumable will be active for 4 seconds longer;
- Starting from Tier VIII, ships are equipped with Surveillance Radar in a dedicated slot. It has an action time of 15 seconds and a range of up to 7.5 km;
- Lack of Smoke Generator and relatively high detection range: when fighting with other destroyers for key areas it’s better to rely on Surveillance Radar and torpedoes.

The armor
For the armor, the ship is protected by 10 mm of armor except for the gun shields that are only 7 mm thick.
Personal Opinion
Let’s see…
Lowest HP pool at this tier? Check.
Worst concealment of all tier IV DDs? Check.
Only decent-ish firepower? Check.
And of course to that list, you can add the classic lack of Smoke Generator and torpedoes with very low damage. You can’t imagine how much I’m praying that they buff these ships before their release for testing… I seriously don’t want to test them right now, especially after the British cruisers that I really enjoyed.
