With the recent announcement from Hasegawa of new Yugumo class releases in 1/700, now seems a good time to set up a thread. The original Hasegawa kits, now 45 years old, were typical of their time in that the detail and armament are very simplistic. The hull is okay, though there’s no rear slope to the stern. The follow-up Pit-Road versions, circa mid 1990s, were a little better in that there is more detail and refinement in the kit parts, but the stern is still wrong, the bridge base is a little short fore and aft, and the bow profile is terrible.

While some modelers see these ships as merely improved Kageros (which they are in many regards), the Japanese consider them a separate class. Several improvements contributed to better sea keeping, stability and maneuverability: The forward main mount was moved 1.5m aft, the bridge was set forward at the same frame number as with the Kagero class, but streamlined to a greater degree, and extended further aft to provide more space. There, it was supported by an open trestle. Also, the stern sloped downward to a more pronounced waterline knuckle, the forward torpedo reload gantries were placed perpendicular to the axis of the ship at #1 funnel, and the main turrets were internally modified to allow barrel elevation up to 75* to improve their AA capability.

From the Wikipedia entry:

“The Yūgumo-class destroyers (夕雲型駆逐艦 Yūgumo-gata kuchikukan?) were a group of 19 destroyers built for the Imperial Japanese Navy during World War II. The IJN called them Destroyer Type-A (甲型駆逐艦, Kō-gata Kuchikukan?) from their plan name. No ships of the class survived the war. (Dan’s note: Many sources, particularly older ones, refer to Akigumo as a member of this class. She was not; she belonged to the proceeding Kagero class.)

The Yūgumo class was a repeat of the preceding Kagerō class with minor improvements that increased their anti-aircraft capabilities. Their crew numbered 228 officers and enlisted men. The ships measured 119.17 meters (391 ft 0 in) overall, with a beam of 10.8 meters (35 ft 5 in) and a draft of 3.76 meters (12 ft 4 in).[1] They displaced 2,110 metric tons (2,080 long tons) at standard load and 2,560 metric tons (2,520 long tons) at deep load.[2] The ships had two Kampon geared steam turbines, each driving one propeller shaft, using steam provided by three Kampon water-tube boilers. The turbines were rated at a total of 52,000 shaft horsepower (39,000 kW) for a designed speed of 35 knots (65 km/h; 40 mph).[3]

The main armament of the Yūgumo class consisted of six Type 3 127-millimeter (5.0 in) guns in three twin-gun turrets, one superfiring pair aft and one turret forward of the superstructure.[2] The guns were able to elevate up to 75° to increase their ability against aircraft, but their slow rate of fire, slow traversing speed, and the lack of any sort of high-angle fire-control system meant that they were virtually useless as anti-aircraft guns.[4] They were built with four Type 96 25-millimeter (1.0 in) anti-aircraft guns in two twin-gun mounts, but more of these guns were added over the course of the war. The ships were also armed with eight 610-millimeter (24.0 in) torpedo tubes in a two quadruple traversing mounts; one reload was carried for each tube. Their anti-submarine weapons comprised two depth charge throwers for which 36 depth charges were carried.[2]”

Lastly, under the Modified 1942 programm, 16 repeat Yûgumo class destroyers were planned in two batches, to be named Umigiri, Yamagiri, Tanigiri, Kawagiri, Taekaze, Kiyokaze, Satokaze, Murakaze (program numbers 348-355) and Yamasame, Akisame, Natsusame, Hayasame, Takashio, Akishio, Harushio, Wakashio (program #s 5041-48, to be known as the Yamasame class.) They were postponed/cancelled in favor of Matsu class destroyers in 1943 and thus never laid down.

Some early war ships below. The Kazagumo photo is interesting in that her forward torpedo storage bays have yet to be fitted.

Some mid war ships. In these, the original, streamlined bridge was retained with the addition of a radar compartment under the compass bridge deck extension aft, under a revised mainmast carrying a Type 22 radar. The 25mm mounts to either side of #2 funnel were changed from twins to triples, and an additional twin 25mm AA mount was placed in front of the bridge.

Some late war ships. The rear of the bridge was enlarged and squared off, eliminating the need for a separate radar compartment. Two additional 25mm triple AA mounts were emplaced on new, raised platform just aft of funnel #1. While the Asashimo photo is not of high quality, one can see the raked stern form, the squared off corner of the rear of the bridge, and most interestingly, two Type 93 “Long Lance” torpedoes. One is sitting on a torpedo trolley on deck beside #2 torpedo mount, and the other is positioned under the starboard torpedo reload girder next to #1 funnel, about to be lowered into the reload bay.

Some illustration and photos regarding the position and shape of the early vs late war bridge. Also, as the first post shows, the front of the Yugumo bridge was placed at the same frame as the of the prior Kagero class. It also gives one a good feel for the difference in the two bridge shapes and the placement of #1 mount. The cupola atop the main rangefinder also differed in the later ships.

Thx for posting, Timmy. Exhibited without turret; I guess it's not quite finished yet. Some slightly larger versions can be seen here: https://twitter.com/HMRF_HOBBY/status/8 ... y-852.html

Some larger pics here; stills from the HLJ TV link.

The turrets aren't finished yet, but most everything else seems to carry a lot of detail. Nicely formed bridge, deck houses (which are separated for easier painting), funnels, the galley exhaust pipe is finely rendered, stern deck is a separate piece (which means a late war version likely). I see some auxiliary deck piping molded on and simplified. It certainly looks better than any version currently out.

A book I have says that the Yūgumo-class was basically an improved Kagerō-class, but with some modifications and improved AA outfit.

I still only see a pair of 25mm Type 96 mounts. Those would have been double-mounts on the Kagerō-class, would they not?

Does this mean they are triple-mounts on the Yūgumo-class?

The first four Yugumos were completed early in the war, with the same AA fit as the Kageros. After that, being war built, newer Yugumos were completed with ever larger, more complete AA fits. First, a change to triples, then additional twins in front of the bridge and more triples to either side of funnel #1.

There's a series of line illustrations in Model Art Ship Modeling Special #30 that lays this out well.

Looks really good to me. All the major issues with the Pit-Road kit appear to have been addressed.

I want to build the Asashimo as she was during operation Ten-go. I'm not sure, where the portholes closed, as other ships?
And where were the single 25 mm located? From the aeroview I see three guns on each side of the bridge. Is this right and where there more?

Greetings Christian

I believe that Asashimo was built with a reduced number of portholes, much as in the Kiyoshimo photo. It's possible that even more portholes, particularly on the lower level, were sealed by early 1945.

I'll check some references tonite regarding the single 25mm AA positions.

Thanks Dan, and the last pic is the one I was refering to. There I see three at the side of the bridge and perhaps two in front of it.
At the aft there are also possibly one next to the deep charge thrower.
And you also see the spare torpedo, which you see on an earlier pic.

I don't believe that is a spare torpedo sitting out on deck. As can be better seen in the previous photo, it appears to be reflected light off the side of the aft deck house that happens to echo the shape to a long object. Besides, it really doesn't make much sense to have a torpedo out on deck during an air attack.

Attached is Asashimo's AA fit diagram as of June 30, 1944. I think it's safe to assume that additional units were added by April, 1945, though the exact number and placement may be debatable.

Thanks Dan, that diagram will help me a lot.
Do have any drawing for the portholes? I will make my according the Kiyoshima pic, But at the aft the position is not clear on that pic.

This survey drawing of Kazegumo in January, 1944 from a Warship International article, shows a porthole arrangement the same as Kiyoshima and, likely, Asashimo. While in Kazegumo's case, it was a matter of sealing off existing portholes, the latter ships' as-built pattern were a match for this pattern. (As a means of comparison, even Yukikaze kept some portholes on the lower row forward, and aft, uncovered through to the end of the war.)

I have my Asashimo painted.
Where there any markings on the ship during ten-go?
On the pics I see nothing, but the 3 Kageros got two white rings on the rear funnel and an unknown sign on the front.
Where the Asashimo in the same division and had the same markings?

Asashimo was not part of DesDiv 17, but rather the flag of DesDiv 21 (Asashimo, Hatsushimo, Kasumi) for Ten Icho-Go. I'm not sure about the funnel bands; I need to check something tonite. She likely would have worn a white chrysanthenum on the sides of #1 funnel, and possibly one of the symbols denoting #1 ship of the division.

Mr research was inconclusive. I can't determine what markings she might have worn. My sense is that DesDiv 21 would have worn one funnel band, probably on the rear funnel. FWIW.
