A Detailed Look At: Roofdier class destroyers9/24/2016 10:57:26 PM
Published By: Lert
Hello and welcome to me waffling on about a ship and explaining how and why it does not fit within this game. I'm talking about the Dutch Roofdier class destroyers.
Beautiful 1/40 model of a Roofdier, possibly Lynx. Note the arrangement of the funnels, especially #3 and #4 separated by the forward torpedo tube.

This ADLA has a few ifs, ands and butts about it, so lets get those out of the way first:

Butt the first: I am fully aware going in to this that this ship wouldn't fit the game. I have decided to write and publish it anyways, for various reasons. 1) I like the class, 2) It's a Dutch built design and there's a modicum of national pride involved and 3) this class is historically significant, though on a rather small scale.

Butt the second: There is contention about what the class was actually called. It's been called the Roofdier class, the Fret class and the Wolf class in various sources. I'm going to stick with Roofdier, because all the ships in the class are named after predators and carnivores, just like all the Admiralens were named after admirals.

Now on to the article itself.

The Roofdier (Dutch for 'Predator') class was an early 20th century Dutch destroyer class, though some might call them torpedo boats. They're sort of an intermediary in many ways. They were based on a British design and built in the Netherlands, utilized British torpedoes and 75mm main guns of unknown manufacture. There were eight in the class, all named after predators. I will list the Dutch name of the ship with the English translation.

HNLMS Wolf (Wolf) was laid down in 1909 in the Dutch coastal city of Vlissingen, launched in September 1910 and completed in 1911. Wolf was stricken in 1924.

HNLMS Fret
(Ferret) was laid down in 1909 in Vlissingen, launched in October 1910 and completed in 1911. Fret was stricken in 1922.

HNLMS Bulhond (Bulldog) was laid down in 1910 in Vlissingen, launched in December 1911 and completed in August 1912. Bulhond was stricken in 1927.

HNLMS Jakhals
(Jackal) was laid down in 1910 in Vlissingen, launched in January 1912 and completed in July 1912. Jackal was stricken in 1928.

HNLMS Hermelijn
(Stoat) was laid down in 1911 in Vlissingen, launched in February 1913 and completed in July 1913. Hermelijn was stricken in 1925.

HNLMS Lynx (Lynx) was laid down in 1911 in Vlissingen, launched in December 1912 and completed in July 1913. Lynx was stricken in 1924.

HNLMS Vos (Fox) was laid down in 1912 in Schiedam, launched in June 1913 and completed in February 1914. Vos was stricken in 1928.

HNLMS Panter (Panther) was laid down in 1912 in Schiedam, launched in September 1913 and completed in March 1914. Panter was reclassified as a dispatch vessel in 1928 and stricken in 1934.

Fret and Lynx were used as a target ship for several years before being scrapped in 1930. The torpedo tubes from various Roofdiers were preserved and later fitted on various motortorpedoboats of the TM3 and possibly TM4 classes.

The Roofdiers were the first naval vessels in Dutch service using turbine engines. Fret, Wolf, Bulhond and Jakhals were coal stoked but Hermelijn, Lynx, Panter and Vos could operate both on coal and oil. They served in a patrol role until being replaced by the Admiralen class in the 20s. I can't find much information whether or not these vessels saw actual combat or not, but I don't think so. The only real opportunity would've been during WWI but the Netherlands were neutral in that conflict.
HNLMS Jakhals, date unknown, probably 1912 judging by the general unspoiled look of 'new'ness.

Historical information is a bit sketchy and hard to find, so how about I hop right into the statistics:

Tonnage:

510 tons normal.

This is where we start to get an incling about why Roofdier wouldn't work in this game. 510 tons normal, let's be generous and give her 650 tons fully loaded. Using dseehafer and fr05ty's formulas that would still only give her 6200 hitpoints, the lowest in the game. Smith has 7300 and Tachibana 7000, and they're the current recordholders for lowest hitpoints in the game.

And that's with me being very generous with the fully loaded figure, taking the base 510 tons, adding the historical 120 tons of fuel and another 20 tons for ammunition and crew.

Armor:

These are tiny, wimpy little tin cans. They didn't have armor.

Main armament:

4x 75mm

Information about these guns is scarce. One source I found calls them '75/52 SA No.1', but a google search for that didn't turn much information up either. Even Navweaps doesn't list any 75mm guns as Destroyer main armament for the Dutch. Still, early 20th century 75mm naval guns, we can all take a guess at how those would perform. I would estimate them to be slightly less powerful than Smith's main guns, and with having one less of them too, we all know who would win in a gunnery duel between Smith and a Roofdier.

Secondary armament:

4x 7.92mm machineguns

Yeah, these would be completely useless in WoWS. Moving on ...

Torpedoes:

2x 1 450mm

That's right, Roofdier had the amazing torpedo loadout of two single tube launchers! They were mounted along the centerline though, with one between #3 and #4 funnel and the second directly aft of #3 gun platform.

According to Netherlandsnavy Roofdiers carried the Fiume Type II45, a 745kg torpedo with a 1000m range at 40 knots and 3000m range at 28 knots. In-game these would have either a 1km range at 60 knots or a 3km range at 48 knots, with the latter being far more likely. These torpedoes carried a 85kg warhead which, again according to fr05tys formulas would equate to 6120 damage.

So how would these function in the game?

Well, taking the 'long range' (ha) option of 3km at 40 knots, we're looking at point blank torpedoes with a low yield warhead that could only with some luck salvo-kill a destroyer if you manage to land the entire Roofdiers torpedo broadside of two fish. They'd probably reload really quickly though.

Anti-aircraft Armament:

I suppose those four 7.92mm machine guns would be able to point vaguely skyward?

Speed:

30 knots

Roofdier carried two Germania-Krupp turbines powered by four Yarrow type boilers, each with their own stack - because these tiny ships didn't have the room to give it less than four stacks.

Being absolutely tiny - considerably smaller than a Smith or a Tachibana - I would expect Roofdier to be quite nimble too.

Concealment:

Just how tiny was Roofdier anyways? Well, let me put it this way. The tiniest destroyer currently in game is Tachibana, which measured 84m long and in-game has a concealment of 5.2 / 2.3.

Roofdier was 70m long...

Were Roofdier to make it into the game, she'd be the tiniest and stealthiest thing afloat. I would estimate we'd be looking at something like 4.5km by sea and 1.9 by air.
HNLMS Wolf, date unknown. Again, judging by the fresh look of its paint and the location I'm guessing 1912.

Conclusion:

Pros:
- Incredibly stealthy!
- Uh ... difficult to hit?
- She's ... pretty, I suppose?
- I'm grasping at straws here, fellas

Cons:
- Middling speed
- Low hitpoints
- Weak torpedoes
- Pathetic range on the torpedoes
- Too few torpedoes
- Weak main armament
- WG sez 'no'

Final thoughts:

In my opinion Roofdier would be a wonderful little tier 1 destroyer premie. Why a premie? Because the Dutch didn't have nearly enough designs for a full tree. Plus the ship that replaced Roofdier, Admiralen, is looking best suited for tier 5 or 6, meaning there's a bit of a gap. Roofdier is too small, too low hitpoints, too weak torpedoes and too little firepower to hold its own at tier 2, so tier 1 is the only place she could fit within the game. Maaaaybe if she were given a fantasy upgrade she never carried in real life like some longer range torpedoes. The British had plenty of fish that would fit.
However, I strongly doubt that we'll ever see Roofdier in the game, no matter how much I would like to.
