The functionality of firearms submerged in water is a complex issue affected by several factors, including weapon type, ammunition, and water depth. A firearm’s mechanical operation can be hindered by the increased density and resistance of water. Additionally, the behavior of projectiles is significantly altered in an aquatic environment.
Understanding how firearms behave underwater is critical for various applications, including military operations, law enforcement, and recreational activities such as spearfishing. This knowledge can influence the design of specialized underwater firearms and ammunition, as well as inform tactical decisions in submerged environments. Historically, the development of effective underwater firearms has presented unique engineering challenges.
