Naval Systems

Moog designs and manufactures high-precision motion control and electronic solutions for many of the world’s leading naval forces. Our marine technologies include electrohydraulic (EH), electrohydrostatic (EHA), and electromechanical (EM) motion control devices for nuclear submarines, deep submersibles, surface and blue water ships. Comprehensive systems are engineered to perform reliably in the harshest of marine environments providing long-life and dependability. Extending our customers’ investments even further is the scalability and upgradeability designed into every component and system along with through life support.

Unmanned Underwater Vehicles (UUVs)

For ROV and UUV platforms, Moog provides motors, controllers, actuators, servo valves, and other equipment. We are making investments in future technologies to support UUVs. Our solutions support steering, diving and propulsion systems as well as other undersea functions for both military and industry.  Moog facilities in the United States, Canada, Germany, and Australia are dedicated to subsea technologies serving the naval and marine industries.

Submarine Actuation

Moog’s legacy supplying actuation in U.S. Navy submarines extends more than 50 years, from the USS George Washington-class all the way to today’s USS Virginia-class and the future Columbia-class. Our critical control systems operate valves, open lock hatches and provide propulsion from the torpedo room to the engine room and everywhere in between. 

Submarine Actuation Applications & Capabilities

Torpedo Steering Systems

Moog supplies the tail cone for the Mark 48 torpedo.  Our servoactuator fin system controls technology enables precision steering to guide Mark 48 torpedoes to intended targets. Moog is also supports torpedo electrification upgrades for propulsion and fin control systems.

Surface Ship Actuation and Weapons

Moog’s legacy supplying actuation in U.S. Navy submarines extends more than 50 years back to the USS George Washington class all the way to today’s USS Virginia class and the future Ohio-class replacement

Moog actuation is also found in mission critical surface ship applications such as the propulsion plants of both USS Nimitz and USS Gerald R Ford class aircraft carriers.

A Dedicated SUBSAFE Manufacturing Facility

Moog’s SUBSAFE, level 1 manufacturing facility in Orrville, OH is dedicated to developing and producing motion control solutions for the U.S. Navy’s nuclear submarine program. Our Orrville sound lab includes a unique structural-borne vibration testing capability for low acoustic signature actuation.

Our motion control solutions comply with stringent naval qualification requirements such as shock, vibration, low acoustic signature, and seawater corrosion resistance. 

Moog Maintains an 89,000 sq ft Engineering and Manufacturing facility in Orrville, OH dedicated to developing and producing motion control solutions for challenging naval applications:

  • Decades of experience meeting stringent naval specific quality standards including SUBSAFE Level 1 and Mil-I-45208
  • Structure borne vibration and test capability
  • Exceptional process capability and repeatability
  • Quality first mindset

Moog manages obsolescence issues:

  • We offer build-to-print manufacture (as well as design & development)
  • Moog owns several legacy product lines from Borg Warner, E-Systems, Montek, and other Naval System and component suppliers

Servo Valves Key to Aircraft Carrier Application

By Matthew McCall, Regional Sales Manager, Moog Inc.

Servo and proportional valves are most commonly flow-control, spool-type valves that meter fluid from a high-pressure source—typically a pump or accumulator system—to a rotary or linear actuator of some sort. From the actuator, the fluid then passes back through the valve, returning to the low-pressure tank or reservoir, making it a “meter-in/meter-out” valve. They control position, velocity, or pressure and/or force through a closed-loop electronic control system. These valves are extremely responsive dynamically, reaching commanded setpoints in milliseconds of receiving a command (generally ~1ms to <100ms).
