Why submarine shaped as whale?

Submarines shaped like whales may be designed to enhance stealth and reduce sonar detection, mimicking the natural hydrodynamics of marine life. This shape can improve maneuverability and efficiency while navigating underwater. Additionally, a whale-like design can serve as a camouflage strategy, blending into marine environments and allowing for covert operations. Such innovations reflect the ongoing integration of biomimicry in engineering and naval architecture.
