Inktober, Day 4: Underwater.

Throwback to the time I toured the USS Bowfin submarine at the Pearl Harbor Memorial in Hawaii. It is a fleet attack sub that fought in the Pacific in WWII. It was launched exactly one year after the Pearl Harbor attack. It sank 22 vessels during its combat years and was nicknamed the Pearl Harbor Avenger. And has a logo that I love and wanted to draw.
