What is one advantage of nuclear propulsion over conventional propulsion?

The advantage of nuclear propulsion allowing for longer underwater operation without refueling is a significant benefit in naval operations. Nuclear-powered submarines can operate for extended periods without the need to surface for fuel, enabling them to remain submerged for months at a time. This capability enhances stealth and operational effectiveness, as submarines can stay hidden for long durations, making them formidable assets in maritime security and warfare.

The ability to remain underwater for prolonged periods is primarily due to the efficient and high energy output of nuclear reactors, which produce a large amount of energy from a relatively small amount of fuel. Unlike conventional propulsion systems that rely on fuel that must be replenished frequently, nuclear reactors have the capacity to run for many years before requiring refueling. This not only extends the operational range but also reduces logistical challenges associated with fuel supply, allowing for greater strategic flexibility in deployment.
