{wiki=Category:173_mm_artillery}
The term "173 mm artillery" typically refers to a type of artillery piece with a 173 mm caliber. However, as of my last update in October 2023, there isn't a widely known or standard artillery piece specifically designated as 173 mm. Most artillery calibers are found in increments of 10 or 20 mm, such as 155 mm or 203 mm.
