Below is a five-page–style summary (approximately 1,500–2,000 words) about the U.S. Navy’s adoption of Xbox 360 controllers for submarine periscope operation, its background, motivations, implications, and broader significance.
Five-Page Summary: The U.S. Navy’s Use of Xbox 360 Controllers for Submarine Periscopes
Page 1 — Introduction and Background
In recent years, the U.S. Navy has undergone a series of modernization efforts designed to streamline operations, reduce costs, and improve the user experience of sailors working with increasingly complex technology. Among the most publicized and surprising of these innovations was the Navy’s decision to incorporate Xbox 360 controllers—a widely available, inexpensive consumer gaming device—into the control systems of some of its most advanced submarines.
This story became widely known around 2017, when the Navy revealed that it had begun replacing traditional periscope control stations on Virginia-class submarines with commercial off-the-shelf technology, including Xbox 360 controllers. Although the idea of using a video game controller on a nuclear-powered attack submarine sounded unusual, the move was the result of a deliberate and well-tested effort to improve usability and dramatically cut costs.
Traditional periscope systems, which had been used for decades, were built around heavy, mechanically intensive control stations. These units included joystick-like handles, wheels, and specialized interfaces that cost tens of thousands of dollars. The new photonics mast systems—modern replacements for conventional periscopes—no longer used a long physical tube that extended upward but instead relied on high-definition cameras, sensors, and digital displays. This shift made it possible to control the periscope electronically rather than mechanically.
With that shift came an opportunity to redesign the control interface entirely—an opportunity that younger sailors and junior officers played an important role in shaping.
Page 2 — Why the Navy Replaced Traditional Controls
At the core of the Navy’s switch was the problem of legacy periscope control hardware. These systems were:
- Bulky and physically heavy, often weighing many pounds and firmly bolted into the submarine’s control center.
- Expensive, with specialized custom-built control hardware costing approximately $38,000 per unit.
- Complicated for new sailors to learn, requiring formal training and experience to operate efficiently.
- Difficult to maintain, given that custom-built components had limited manufacturing sources and required specialized technicians for repair.
When the Navy introduced photonics masts—digitally controlled periscopes with camera feeds instead of optical lenses—design teams connected the mast systems to large screens that displayed 360-degree visuals. This modernization prompted engineers to question why the old control methods were still being used when the rest of the system had gone digital.
As part of the evaluation process, the Navy conducted usability testing by inviting junior officers, new recruits, and younger sailors—many of whom grew up playing video games—to try different types of controllers. In an era when most young service members had spent years using game controllers in their personal lives, the feedback was clear: a commercial game controller was more intuitive, more comfortable, and faster to learn than the traditional mechanical hardware.
The sailors overwhelmingly preferred an Xbox 360 controller, citing reasons such as:
- Familiar button layout
- Ergonomic design
- Lightweight, handheld use
- Precise control with analog sticks
Because sailors already understood the interface from civilian life, training time dropped from hours to minutes. This kind of immediate skill transfer became a compelling advantage for Navy planners.

One of the Navy’s biggest incentives was cost efficiency. While the legacy periscope controls cost nearly $38,000, an Xbox 360 controller—purchased commercially—cost around $20. Even after ruggedization, backups, and integration with submarine systems, the savings were dramatic.
Key Benefits
1. Dramatic Cost Reduction
Using consumer hardware reduced per-unit costs from tens of thousands of dollars to just a few dollars. This also meant that replacements were easy to source, inexpensive, and could be stocked in large quantities.
2. Reduced Training Time
New sailors could be trained in minutes instead of spending extended time learning how to use traditional systems. Training pipelines shortened, and operational readiness improved.
3. Increased Durability and Ease of Replacement
Xbox controllers are mass-produced and designed to endure thousands of hours of intense button-pressing. If one broke, it could be swapped out quickly without expensive repair procedures.
4. Greater Ergonomics and Human Factors Design
The gaming industry has invested heavily in ergonomics. The Navy effectively leveraged decades of R&D funded by consumer entertainment companies, improving comfort and precision for sailors during long shifts.
5. Integration with Digital Systems
Photonics masts produce digital sensor data. A digital controller with USB connectivity made integration straightforward and reliable.
Implementation Within Submarines
The Xbox controllers were incorporated directly into the Virginia-class submarine’s control room, connecting to the photonics mast control station. Instead of a single operator controlling a heavy mechanical periscope, multiple sailors could access camera feeds simultaneously on large touchscreens. The controller allowed operators to:
- Rotate the mast
- Adjust zoom
- Control focus
- Navigate through sensor modes
- Select different viewing angles
The shift also changed the submarine’s layout, freeing up space and enhancing efficiency within the control center.
Page 4 — Impact on Naval Operations and Military Technology Trends
The decision to use a gaming controller reflects a broader trend across the U.S. military: embracing commercial off-the-shelf (COTS) technologies whenever possible. The benefits of COTS systems include affordability, rapid development cycles, widespread familiarity, and ease of replacement.
Operational Impact
1. Faster Modernization Cycles
Instead of waiting years for custom military hardware to be designed and built, the Navy could upgrade interfaces quickly and at low cost.
2. Improved Morale and User Experience
Junior sailors appreciated the intuitive interface, which made them more confident and efficient. This helped reinforce training and reduced operational stress.
3. More Flexible Design Philosophy
The success of the Xbox controller on periscopes encouraged engineers to consider commercial hardware for other systems. This shift represented a cultural change within the Navy—an acknowledgment that military systems do not always need to be custom-built to be effective.
4. A Lesson in Human-Centered Engineering
The controller story underscored the importance of collecting feedback from real end-users—in this case, young sailors—rather than designing systems top-down without user input.
Broader Military Trend
The Navy’s adoption of gaming controllers aligns with similar innovations across the U.S. Armed Forces:
- The Army has tested HoloLens-based augmented reality systems for soldiers.
- The Air Force uses commercial VR headsets for pilot and drone operator training.
- Drone operators in various branches use interfaces modeled after gaming setups.
This trend recognizes that younger generations often enter the military with advanced familiarity in digital interfaces, controllers, and gaming systems—skills that can be translated directly into military operations.
