How Long Can a Nuclear Submarine Survive in Space?

TLDRNuclear submarines are not designed to survive in space due to several reasons. While they can withstand high external water pressure and have airtight hulls, the lack of water in space prevents them from extracting oxygen. The biggest challenge, however, is overheating, as space is much warmer than the ocean. Without a way to dissipate heat, the submarine's nuclear reactor would lead to a meltdown within an hour. Additionally, the submarine lacks the capability to slow down and leave orbit without rockets. Using the ballistic missiles in reverse could provide a temporary speed change, but the submarine would inevitably break up upon reentry.

Key insights

🚀Nuclear submarines are not designed for space travel and would not survive due to overheating caused by their nuclear reactors.

🔥The lack of water in space prevents nuclear submarines from extracting oxygen, making it impossible for them to produce more air.

❄️Despite space being cold in terms of average kinetic energy, the absence of air or water to carry heat away would lead to overheating.

💥Nuclear submarines lack heat dissipating ablade of tiles and aerodynamic stability, causing them to break up upon reentry.

💡Using the ballistic missiles carried by nuclear submarines in reverse could provide a temporary speed change but would not be enough to safely leave orbit.

Q&A

Why can't nuclear submarines survive in space?

Nuclear submarines are not designed for space travel and face several challenges that make it impossible for them to survive, including overheating, the inability to extract oxygen, and the lack of heat dissipation mechanisms.

Could a nuclear submarine produce its own air in space?

No, nuclear submarines rely on extracting oxygen from water, and without water in space, they would not be able to manufacture more air.

Is space cold or warm?

In terms of average kinetic energy, space in Earth's orbit can be very cold. However, due to the absence of air or water to carry heat away, space can be warm for objects in it.

Can a nuclear submarine slow down and leave orbit without rockets?

No, a nuclear submarine does not have the necessary propulsion systems to slow down and leave orbit. Launching its ballistic missiles in reverse could provide a temporary speed change, but it would not be sufficient for safe departure from orbit.

Could anyone survive in a nuclear submarine reentering the Earth's atmosphere?

The chances of survival for anyone inside a nuclear submarine during reentry into the Earth's atmosphere are extremely slim. The submarine lacks the necessary heat dissipating mechanisms and aerodynamic stability, leading to its breakup upon reentry.
