Notes

Japanese cruiser Jintsū (神通) (じんつう) was the second vessel completed in the three-ship Sendai-class.

oni-sendai-2

Commissioned in 1925, On 13 July 1943 in the Battle of Kolombangara, she was discovered during a night attack by American ships and sunk in combat.

Key events from the record of movement:

  • 8 December 1923: Launched at 0800 and named JINTSU.
  • October 1931: The Kure Type No. 2 Model 2 catapult, previously tested aboard KINU, is transferred to JINTSU. An Aichi E3A1 Type 90 Mod. 1 reconnaissance floatplane is embarked.
  • 6 December 1941: Operation “M” - The Attack on the Southern Philippines
  • 12 December 1941: The Invasion of Legaspi, Luzon
  • 17 December 1941: Operation “M” - The Attack on the Southern Philippines
  • 19/20 December 1941: The Invasion of Davao, Philippines.
  • 23 December 1941: The Invasion of Jolo, Philippines.
  • 9 January 1942: Operation “H” - The Invasion of Celebes, Netherlands East Indies
  • 17 January 1942: JINTSU launches a reconnaissance floatplane, probably a Kawanishi E7K2 “Alf”. The pilot claims downing a Dutch Lockheed A-29 “Hudson” light bomber near Menado. The victory is short-lived because soon thereafter, the floatplane is shot down.
  • 31 January 1942: The Invasion of Ambon Island, Netherlands East Indies
  • 27 February 1942: The Battle of the Java Sea
  • 28 May 1942: Operation “MI” - The Battle of Midway
  • 24 August 1942: The Battle of the Eastern Solomons
  • 31 January 1943: Operation “KE” - The Evacuation of Guadalcanal
  • 13 July 1943: The Battle of Kolombangara: sunk
    • Transport Group from Buin, carrying troops and equipment to be landed at Vila on Kolombangara Island
    • at 0036, a PBY Catalina reports the sighting of the Japanese squadron to Rear Admiral Walden L. Ainsworth, leading Task Group 36.1
    • At 0108, JINTSU snaps on her searchlights to illuminate Ainsworth’s force. Two minutes later she is taken under the radar-controlled fire of three cruisers.
    • Around 0145 a torpedo hits JINTSU at starboard aft engine room. A massive explosion follows; the cruiser breaks in two abaft the middle funnel and sinks three minutes later at 07-38S, 157-06E.

Finding of the Wreck

February 2019: Microsoft co-founder Paul G. Allen’s research vessel RV PETREL locates the wreck of JINTSU a depth of 2,952 ft. Her bow section is lying on her port side while the stern section is upright.

The Kit

The Fujimi Kit No. 40123 is a 1st generation tooling from 1973.

I’ve used a few upgrades, though these are far from essential:

Paint Scheme - Jintsū

Feature Color Recommended Paint Used
    H8  
    H11  
    H12  
hull   H17 H17
    H18  
Deck   H37 H37
Superstructure   H83 H83
  flat red H13/H3+H20  

Paint Scheme - E7K1

The Fujimi kit includes an Nakajima E8N Navy Type 95 Reconnaissance Seaplane Model 1 but it appears most likely that Jintsū normally carried an Kawanishi E7K2 Navy Type 94 Reconnaissance Seaplane Model 2.

For the plane, I’ve used an E7K1 from Sky Wave Series Equipment For Japanese Navy Ships-WW2 (Set 7) Pit-Road No. E12 1:700.

Feature Color Recommended Paint Used
prop and Black   H12
fuselage Silver   H8

Build Log

Although a tooling from 1973, the kits is still remarkably buildable. Superstructure details is a little soft, but overall not bad.

This time I am experimenting with a hand-carved wooden base to simulate the sea.

Working up the sea surface. Painted with Vallejo Model Color with layers of Mod Podge Gloss. Cotton wool for the foam and crests of the wake.

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is just my personal collection of projects. Two main themes have emerged in recent years, sometimes combined:

  • electronics - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting
  • scale modelling - I caught the bug after deciding to build a Harrier during covid to demonstrate an electronic jet engine simulation. Let the fun begin..
To be honest, I haven't quite figured out if these two interests belong in the same GitHub repo or not. But for now - they are all here!

Projects are often inspired by things found wild on the net, or ideas from the many great electronics and scale modelling podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know (or send a PR!). See the individual projects for credits where due.
