A Detailed Look At: van Kinsbergen sloop

Welcome to an unprecedented ADLA, in which I will do what no ADLA has ever done before, on this blog! To my knowledge!

So far we’ve had cruisers, light, protected and heavy. We had battleships, bricks and speedsters alike and everything in between. We had battlecruisers, carriers, destroyers, flotilla leaders. We’ve had ADLAs about ships that were later added to the game, ships that we didn’t know just how to tier and ships that turned out about spot on compared to how we thought they were going to. We had ADLAs about ships that were a perfect fit in this game, and ships that simply won’t fit. But we’ve never had an ADLA …

… about a tier 1 ship.

Mostly because nobody really cares about tier 1 ships.

Yet, tier 1 ships fill a very important role. They are the cornerstone upon which the entire tech tree leans. They are the first ship someone encounters, going up a tech tree. They are the flavormakers, they are th – …

… Oh.

You still don’t care about tier 1 ships?

Then at least maybe I can make you care about the history behind this ship. Because for such a small ship, technically remarkable for being totally unremarkable, she has a lot of history.

I present you, the sloop HNLMS van Kinsbergen.

Built by the Rotterdamsche Droogdok Maatschappij, the unique sloop van Kinsbergen was laid down in Rotterdam on september 11, 1937, launched on January 5, 1939 and commissioned August 4, 1939. She was sent to the East Indies to take over patrol duties from the smaller and aging sloop HNLMS Johan Maurits van Nassau. During this trip van Kinsbergen was escorted by the Dutch submarines O-15 and O-20. She arrived at Curacao on October 31st.

On the evening of November 1st, van Kinsbergen left port to intercept a British destroyer that had entered national waters, something forbidden following the Netherlands’ declaration of neutrality. Quite what this little sloop was intended to do against a destroyer, I don’t know – although the van Kinsbergen possibly had a heavier gun armament than many Royal Navy destroyers in active duty at the time, she was slower and had no torpedoes. Later a small British cruiser entered territorial waters too and once again van Kinsbergen was sent out. Both times the situation was resolved without using force.

After war broke out on May 19th, 1940, boarding parties from van Kinsbergen captured eight German merchantmen laid over at Curacao ports. These captured ships were transferred to the autority of the KNSM, an Amsterdam based shipping company. van Kinsbergen was placed under British command and undertook several more missions to capture merchantmen and rescue survivors of torpedoed vessels.

Wikipedia talks about how the New Orleans class heavy cruiser USS Tuscaloosa at one point met the van Kinsbergen, where the latter gave a demonstration of her armaments. It speaks of how the Americans were most impressed by the performance of the 40mm guns, of how the Hazemeyer patended stabilized gun mount allowed the Dutch gunners to achieve remarkable performance. The Americans were so impressed that they decided they wanted this system. To protect their patents, the Swedes were not eager to hand over the Bofors blueprints to the US. The Americans could not wait for what they considered to be trivialities and obtained the blueprints through the Dutch navy. The Dutch had them in safekeeping in the still unoccupied Netherlands East Indies. Only after the war were the Swedes compensated for this. Wikipedia lists a book source for this information, but I’ve been unable to doublecheck whether this incident actually happened or not.

As the war continued, van Kinsbergen continued to patrol the waters of the Dutch east indies, and captured more freighters. Wikipedia speaks of a period between December 1940 to June 1941 where van Kinsbergen captured 12 ships totalling 49.486 tons. In 1944 she made her way to New York where she was fitted with a new ASDIC system as well as a new search radar.

In-between periods of repair and overhaul she spent the war escorting convoys, hunting submarines, capturing merchantmen and undertaking  general patrols. During this period she received the nickname ‘Flying Dutchman‘.

She survived the war intact, and in 1951 was reclassified a Frigate, having her main armament of 4x 120mm guns replaced by 2x 105mm guns. Between 1955 and 1959 she was used as an accomodation ship. After decomissioning in 1959 she spent 15 years rotting in place until sold for scrap in 1974. Such an ignominous end for such a proud ship that is assuredly a candidate for most successful Dutch surface ship of the war.

Now lets get to the nitty gritty, shall we?


van Kinsbergen displaced 2388 tons full load. This puts her 500 tons behind Erie and 200 behind Bougainville. However, van Kinsbergen displaced more than double the tonnage of Hashidate.

This is where I would normally give an estimate of the amount of hitpoints a given ship would have, based on formulas derived by Fr05ty. However, his formulas only apply for tier 2 and up, since tier 1 operates in its own little universe. Plus, tonnage -> hitpoints doesn’t count for tier 1 anyways, as Erie displaces about 250% of Hashidate, yet in this game Hashidate has the higher hitpoint pool.

If I were to venture a guess though, and this is nothing more than a guess, I would put van Kinsbergen at 4500 hp.


Historically van Kinsbergen had a 13mm belt, with a 20mm deck and 20mm conning tower. This would put her right in the middle of the pack where armor on tier 1 ships is concerned. Nothing to write home about.

Main armament:

4x 1 Bofors 120mm Mk 6

These were Bofors designed but license-built Dutch manufacture 120mm guns, firing a 53 lbs HE shell at 899 mps. These guns achieved a rate of 10 shots per minute. The Mark 4, 5 and 7 of these guns had a maximum range of 19500. I’ve been unable to find what the maximum range of the Mk 6 guns was, just that they could elevate to 45 degrees, where the Mks 4, 5 and 7 could only reach 35 degrees of elevation. These guns were situated inside an armored, manually traversed turret that could traverse between -150 to +150 from the axes of the ship.

Auxilliary armament:

4x 40mm

4x 12.7mm

2x Depth Charge Racks

Irrelevant at tier 1.


van Kinsbergen could manage 25.5 knots.

Equipped with twin shafts and a 17000 hp triple expansion powerplant, van Kinsbergen managed a rather impressive speed, for her type. If implemented with her historical speed she would be the fastest tier 1 in the game, beating Orlan by half a knot and Hermelin by 1.5 knots.


van Kinsbergen was about the size of Erie, and I would imagine she’d get similar concealment.


Yeah I know that tier 1 ships aren’t very exciting, and initially I wasn’t going to do this article. But as I learned more about the history of this fascinating little sloop I just couldn’t resist making a thread. I’m not going to pretend that having a suitable tier 1 is ‘an integral piece of the puzzle‘ and that ‘having found one increases the likelyhood of a Dutch tree‘ yadda yadda. It’s just a matter of me finding an interesting Dutch ship and wanting to write about it.

Thank you for indulging me.
