Can a Desert Eagle Fire Underwater?
The Desert Eagle, a powerful and iconic handgun, is often used in popular culture as a symbol of toughness and versatility. Its massive caliber and striking appearance make it a fan favorite among firearms enthusiasts. However, its underwater performance has always been a topic of debate. In this article, we will dive deeper into the question of whether a Desert Eagle can fire underwater and what makes it difficult to do so.

The Basic Problem with Firing Underwater
To fire a firearm, three elements are required: ignition source, fuel (gunpowder), and an atmosphere with the correct conditions (air) for the burning process. Water does not provide a suitable atmosphere for firing, and there are several reasons why a Desert Eagle, or any firearm for that matter, cannot fire underwater:
- Insufficient Oxygen: Water has a density much greater than air, making it extremely difficult for oxygen to diffuse to the propellant, causing incomplete combustion.
- Gas Bubble Formation: As water compresses gas molecules, air pockets are trapped in the cartridge and in the bore of the weapon. When fired underwater, these air bubbles collapse quickly, creating significant back pressure, leading to premature bullet fragmentation.
- Temperature and Pressure Changes: Seawater temperatures range from -1.4°C to 24.7°C, making it essential to have the optimal ammunition designed specifically for this range. Pressure underwater can cause stress fractures, further weakening the ammunition’s reliability.
- Cartridge Failing: In-water operation increases the pressure inside the cartridge case, potentially leading to casing rupture, reducing accuracy, or causing other mechanical malfunctions.
In-Situ Ignition vs. Self-Containment
Firing a Desert Eagle underwater is divided into two fundamental concepts:
- In-situ Ignition: Attempts to create a combustion process within the cartridge while still submerged.
- Self-Containment: Uses underwater containers, storage tanks, or devices designed to manage propellant release, to mimic surface-fired cartridges.
Let’s look at both options and what they require to achieve effective firing.
In-situ Ignition Attempts
In-situ ignition strategies rely on finding an adequate ignition source to light the propellant, compensating for water’s stifling effect. Techniques to do this have included:
• Explosive Bridgewire: Utilize a sensitive bridgewire connected to the propellant to trigger detonation when sufficient current flows. Limited applications, sensitive materials needed.
• Laser Initiation: Fire a precision-guided laser at a critical component (bridgewire) or surface-enhanced region (enhancing propellant ignitibility) for the required energetic interaction.
Inhibiting Success: Energy Disruption, Viscosity, and Material Dilemmas
Energy-disrupting, water-invasive elements prevent optimal function and efficient operation in water-based scenarios. Specifically, under water’s hostile environment, you need:
- Robust Power Supply: The source providing electrical or energetic inputs would have to withstand severe degradation or interference caused by seawater (ion-rich) corrosivity and thermal limitations.
These energy challenges render existing concepts unreliable. Energy disarray from fluid’s impedance raises further complexities for an electrical bridgewire approach (insensitive components will lose potency underwater), even an initial light (a bridgewire fails), leaving self-illumination from heat loss during detonation difficult for proper self-lamination in cold (relativizing high current energy at ambient.
Another complication results from pressure forces during disassembled systems where all (all 14 chambers for both stages to control for heat. No chambered ignition could survive that (relaxed (compounded further through friction at different times by

The End Result
Considering these points, in-situ ignition of the Desert Eagle (or any other cartridge firearm) for underwater applications seems nearly impossible, primarily due to difficulties with creating and sustaining reliable combustion conditions underwater.
Instead, specialized containers and containment devices should be utilized. For practical use in scenarios such as scientific, filmmaking, or marine environmental exploration projects.
