Do Military Submarines Have Windows?
For many people, the image of a military submarine often conjures up visions of a sleek, underwater vessel with rows of portholes or windows, much like a surfaced submarine or a naval battleship. However, when it comes to military submarines, this image is misleading. Unlike their surfaced cousins, most military submarines lack windows.
Why Military Submarines Don’t Need Windows
Military submarines operate largely in the depths of the ocean, far from prying eyes or potential attack. As a result, they don’t require visible windows to observe their surroundings like a surfaced vessel would. In fact, having visible windows would provide a strategic vulnerability, compromising the entire mission of remaining undetected.
Submarines rely on more advanced surveillance systems, including:
- Periscope assemblies: These flexible tubes project above the surface, providing a limited range of visual observation.
- Bathymetric sensors: These sensors scan the ocean floor, producing detailed charts of underwater topography, helping the crew navigate through treacherous waters.
Types of Windows Submarines Can Have (But Don’t Need Them)
Though military submarines don’t typically have transparent windows, some specialized sections may feature various types of windows or glass-like openings:
- Emergency surface windows: Located near the control room, these manually operated windows permit the crew to quickly regain access to the surface, allowing escape or rescue. Type 1 Midgets, a Russian submarine used during World War II, had emergency hatches called "sneezedrums," which featured glass panels.
Security Considerations: Why Avoid Windows
Eliminating traditional windows provides enhanced security benefits:
- Radio-absorption: Windows or portholes can conduct radio waves, potentially giving away a submarine’s presence.
- Pressure hull vulnerabilities: Windows pose a structural risk to the pressure hull, which withstands immense external pressure.
Submarine Design Workarounds for Visual Aids
So, without windows, how do crew members maintain a visual perspective? Submarines compensate with:
• Magnetic compass: A robust magnetic compass serves as an essential navigation tool.
• Sonar and bathymetric imaging: Synthetic aperture sonar (SAS) systems and depth sounders offer detailed bathymetric imaging, permitting the crew to chart seafloor geography.
• Thermal imaging systems: Some subs employ heat-sensing arrays to scan the surrounding ocean, often used for early warning or surveillance.
Conclusion: The Importance of Stealthiness
Military submarines prioritize silence, speed, and subtlety above all. The absence of windows – or any optical windows that could compromise visibility – helps maintain their reputation as deadly, invisible force multipliers. By optimizing their operations around advanced technologies and security considerations, they remain some of the world’s most formidable underwater threats.
Here’s a brief summary table:
| Factor | Pros | Cons | Conclusion |
|---|---|---|---|
| No windows | Enhanced stealth, reduced noise, pressure hull integrity maintained | Visual observation limitations | Critical decision for military subs |
| Periscope assemblies | Limited visual coverage, simple installation | Narrow field of view, cumbersome | Optional, not typical |
| Bathymetric sensors | Detailed seafloor data, navigation precision | Depth limitations, vulnerability to EM interference | Mainstay surveillance tool |
| Emergency surface windows | Permits speedy escape or rescue | Strategically vulnerable | Rare on military subs, typically absent |
