Help Request: Gun Batteries Defending Midway (3" / 5" / 7")


Recommended Posts

Hello Guys,

Ok first task I need help with on this subject is what type of guns were used in the defense of Midway by the USMC and USN.

There were three types - 3 inch, 5 inch and 7 inch. This map shows their locations.

The questions we need answers to are:

1. Which models or marks were used at each battery? All these guns had several marks and evolved over time.

2. Where they general artillery or an anti-aircraft gun or a dual-purpose gun?

3. What kind of mount did they use? Low-Angle or High-Angle? 

If we can answer these questions I can research the guns and have the proper models built.

Anyone have any thoughts or helpful info to share?

Thanks in advance for any info you may have!

Maybe no help, but the 5" guns on Wake Island when attacked were taken from 1892 battleship USS Texas. Is it possible that the same type were on Midway? Plus I expect you've seen this but when the Japanese shelled Midway at the opening of the war the islands were defended by 5 inch (127 mm) guns, built in 1916, and 3 inch (76 mm) guns of 1921. First Bombardment of Midway - Wikipedia There is also a picture of a shore gun along with the article. Whether these were the same guns in 1942 though...

Cheers.

Hey guys,

Thanks for the tips. My research today indicates that on Midway the larger guns used for coastal defense and AAA were:

3 inch / 50 caliber "High-Angle" Dual Purpose used for both anti-ship and anti-aircraft. 

5 inch / 51 caliber Shore Battery mount used for anti-ship. Removed from ships and re-purposed on Wake and Midway.

7 inch / 45 caliber Shore Battery mount used for anti-ship. Removed from ships and re-purposed for coastal defense. I see no other option for Midway in this case.

I have ordered a book that I think will give me all I need to build beautiful models of these guns. Fingers crossed once it arrives. I'll keep you posted. Now onto other missing details on the island.

As a follow-up to discord, here are good archival videos of the elusive 3 inch AA gun

packaged above on wetransfer, but the original files are here anyway https://catalog.archives.gov/id/24636

Several variants of the 3 inch AA gun are on display. The ones with automatic pointing in fixed emplacements deployed as a battery are likely M3s I suppose? But I could be wrong.

At any rate at the beginning of video 2 you get several shots show the deployment of the spider chassis as seen in the scale model posted by m0ther_bra1n3d

Obviously not enough to make a 3D model out of it all, but very precious as far as operations are concerned.
