Navy Proficiency Badges
1st Class
Here are some photos of the 1st Class Navy Proficiency badges. There are 10 different badges,
according to Peterson. As you can see, I do not have an example for each one, so if anyone can
help with a photo, I'd appreciate it.

The title of each badge is that provided by Peterson. In parentheses I have put the English
translations I found in a Japanese source. That source called the 2nd Class badges 'Superior
Badges' and the 1st Class badges 'Superior Ensigns.' The English titles (names) are
somewhat different, too, and some may be more accurate than Peterson's choices.

(Mechanic Handling Superior Ensign)
Instituted on September 8, 1911 (Meiji 44)

I'm not sure of the reason between the date of the creation and the announcement of this badge.

Awarded to NCOs who were Navy machinists. They had to pass tests in war maneuvering, electrical maintenance and
operation, controlled fires, supplying water, supplying oil, etc.
