180 mm/57 (7.1") B-1-P Triple

3D Model

180 mm/57 (7.1”) B-1-P Pattern 1932

A Soviet gun that was used on warships, railway artillery and coastal artillery. Since the pattern 1931 wasn’t satisfactory a new gun design with a lower muzzle velocity and shorter barrel length designated the 180 mm/57 B-1-P Pattern 1932 was produced. Early prototypes were of built-up construction, but in 1932 the technology for producing loose liners was purchased from the Italian firm of Ansaldo.

This high-poly model depicts a triple mount.

note about the rifling: Since I could only find information on the number of grooves, I used the 130 mm/55 (5.1”) Pattern 1913 gun as a basis to fill in the blanks (twist, width of the lands, space between the grooves and the depth of the grooves). Rifling is not historically correct.
