Who is credited with founding the Nuclear Navy?

• A. Grace Hopper
• B. Hyman G. Rickover
• C. John Adams
• D. Chester Nimitz

Answer: (B)

The idea being tested is who established the Navy’s use of nuclear propulsion and the safety, training, and organizational framework that made it possible. Hyman G. Rickover is widely recognized as the driving force behind the Nuclear Navy. He championed a rigorous, safety-first approach, created the Navy’s nuclear training and reactor oversight programs, and led the development of the first nuclear-powered submarine, USS Nautilus. Under his leadership, the Office of Naval Reactors (and associated Navy culture) ensured reliable, safe operation of the fleet’s nuclear reactors for decades, earning him the title “father of the Nuclear Navy.”

Grace Hopper is celebrated for advances in computer science, not naval nuclear propulsion. John Adams is a Founding Father with no connection to naval nuclear development, and Chester Nimitz was a WWII fleet admiral who preceded the nuclear program rather than founding it.
