The U.S. Navy sports the largest and most effective submarine force in the world, with 53 fast attack submarines, 14 ballistic-missile submarines, and four guided-missile submarines.

Did you also know that the Navy’s fleet of ballistic submarines holds 54 percent of the United States’ nuclear deterrent arsenal? Oh, yes. You read that correctly. More than half of the country’s nuclear defense weapons are located on dozens of nuclear submarines.

The Navy’s submarines are worth billions, and submarine defense initiatives continue to be a multibillion-dollar industry. What makes these submarines particularly interesting, however, is the platform technology they employ to defend our nation’s borders, prevent war, and protect American lives.

The major Navy submarine technology programs include the Electronic Warfare Support System (BLQ-10), the Combat Control System (BYG-1), the A-RCI Sonar System (BQQ-10), and the Integrated Submarine Imaging System (ISIS or BVY-1).

Lockheed Martin and General Dynamics, respectively, are the hardware and software leads for these programs, which receive COTS technology refreshes every two to four years.

Keep reading to learn more about each of these programs, how Navy submarine commanders and crew members use them to keep Americans safe, and how cyber-secure, ruggedized, USA-made servers and workstations are the future computing powerhouses for these mission-critical systems.

AN/BLQ-10: The Submarine Electronic Warfare Support System

The Submarine Electronic Warfare Support System, also known as AN-BLQ-10, is the Navy’s undersea repository for detection, classification, localization, and identification of incoming, potentially unfriendly radar and communications signals. It’s a singular system comprised of several subsystems used for both signals intelligence gathering and processing when a submarine is at periscope depth.

The AN-BLQ-10 can be found on the Navy’s Virginia-class, Los Angeles-class, Seawolf-class, and Ohio-class submarines, and will eventually be installed on its Columbia-class ballistic missile submarines, which are scheduled to be delivered to the Navy in 2027.

How does AN/BLQ-10 work?

The AN/BLQ-10 processes signals collected from the submarine’s masts. The imaging mast, which can be either a photonics mast or a periscope, collects radar and communications signals, whilst a dedicated communications signals intercept mast is used on Virginia-, Los Angeles-, and Seawolf-class submarines.

Submarine commanders use the AN/BLQ-10 to conduct underwater intelligence, surveillance, and reconnaissance operations to accomplish mission objectives, as well as coordinate with and support other submarines in the fleet. A submarine commander’s primary goals with the AN/BLQ-10 system are:

  • Warning of potentially hostile threats to avoid vessel collision and counter-detection
  • Determining the number and location of threats for subsequent action

What about the system’s hardware and software?

The AN/BLQ-10 has an open systems architecture, with its hardware and software being updated every two years.

The first AN/BLQ-10 technology insertion (TI) upgrade was TI-08, which added a subsystem for improved interception of low-probability radar signals. TI-10, on the other hand, included updates to commercial-off-the-shelf (COTS) processors and displays, upgrades of the radar narrow band and Improved Communications Acquisition and Direction Finding (ICADF) system, and improvements to the signals collection process.

TI-12 saw the installation of new high-performance servers and integration of some TI-10 capabilities, as well as a standardization of cybersecurity, on the Los-Angeles class submarines. TI-14 consists of updates to COTS processors, displays, and what’s called the Electronic Warfare Server First Generation, the purpose of which is to provide Electronic Support System (ESS) decision-makers with improved situational awareness.

AN/BYG-1: The Combat Control System

The Combat Control System, also known as AN/BYG-1, is the Navy’s official undersea weapons and tactical defense system for tracking and analysis of other submarines and ships, establishment of situational awareness, and aiming and firing of heavyweight torpedoes and Tomahawk land attack cruise missiles.

The AN/BYG-1 can be found on the Navy’s Virginia-class, Los Angeles-class, Seawolf-class, and Ohio-class submarines. The Navy first installed the systems on operational vessels in 2010. The system’s COTS computer technology and software replaced the submarines’ central processors and integrated the submarines’ Tactical Control System (TCS) and Weapon Control System (WCS).

How does AN/BYG-1 work?

The AN/BYG-1 enables submarine crews and commanders to complete the following tasks quickly and efficiently:

  • Aiming and firing of torpedoes and missiles against enemy submarines and surface ships
  • Processing of organic sensor data and collection of external intelligence to establish undersea awareness
  • Analyze sensor contact data to monitor other submarines and surface vessels located in the open ocean and near the shore
  • Plan, coordinate, and execute torpedo and missile strikes and related missions

What about the system’s hardware and software?

Like the AN/BLQ-10, the AN/BYG-1 employs an open systems architecture, with its hardware and software being refreshed biennially to address COTS obsolescence and equip the system with newer, and better, technologies.

The system is powered by COTS computers and sensors, which are integrated via the TCS to provide commanding officers and crew members with a shared strategic picture, one that’s continuously changing based on variations in the undersea environment. This is accomplished by exploiting the capabilities of multiple systems, including sonar, radar, navigation, electronic, and communications.

A-RCI and ISIS: The Sonar and Periscope Imaging Systems

AN/BQQ-10: The A-RCI Sonar System

The Acoustic Rapid Commercial-Off-the-Shelf (A-RCI) Sonar System, also known as AN/BQQ-10, is the Navy’s active and passive sonar sensing system. It’s used to conduct anti-submarine warfare (ASW), allowing officers and crew members to detect, classify, localize, and track enemy submarines and other undersea objects, such as mines, the ocean floor, fish, and surface or littoral ships.

Like the Electronic Warfare Support System and Combat Control System, A-RCI has an open systems architecture to promote rapid adoption of new and improved COTS rugged servers and embedded computing technologies, hence its name. Software and hardware upgrades occur every two years and every four years, respectively.

The system is designed to process sonar-acquired environmental data and display it in a way that makes it easier for sonar operators to use. It’s also used by commanders to support covert Naval Special Warfare missions and assist with under-ice operations.

AN/BVY-1: The Integrated Submarine Imaging System (ISIS)

The Integrated Submarine Imaging System (ISIS), also known as AN/BVY-1, is a specialized digital imaging system for submarine periscopes. It uses high-definition cameras and fiber-optic digital imagery to feed real-time displays to Navy officers and crew members.

The AN/BVY-1 can be found on Los Angeles-class, Seawolf-class, Ohio-Class, and Virginia-class submarines. Like most Navy systems, it, too, possesses an open systems architecture, with technology refreshes occurring periodically.
