General Dynamics Electric Boat Division Groton, CT

Atlantic Hydraulic Systems was commissioned to design and manufacture the first article hydraulic systems including the hydraulic power unit and hydraulic manifolds that would allow the launch and recovery of unmanned underwater vehicles and other payloads from the missile tube of a cruise missile submarine.

The Universal Launch and Recovery Module (ULRM) was developed by General Dynamics engineers to articulate the Lockheed-built 10,000-pound prototype vehicle called Marlin, from the submarine’s missile tube.

The NAVY is anticipating the utilization of this type system on new build submarines.

Atlantic Hydraulic Systems designed and manufactures the hydraulic power unit, manifolds and computer control circuitry for the NAVYs fleet of Dry Dock Shelters.

The hydraulics are utilized for several functions on the vehicle which are confidential and are operated by the operational NAVY SEALs.

The Dry Deck Shelter (DDS), fitted aft of the submarine’s sail structure, is connected to the submarine’s after hatch to permit free passage between the submarine and the DDS while the submarine is underwater and approaching the objective area. Then, with the submarine still submerged, the SEALs can exit the DDS and ascend to the surface or objective area.

The Navy’s maneuvering and seakeeping (MASK) basin simulates wave conditions to test the stability and control of scale models up to 30 feet in length so the Navy can predict how the full-scale vessels will perform on the ocean.

The Atlantic team was honored to be part of the team that designed and manufactured the 216 paddle wavemaker that produces precise waves to simulate sea conditions for ship hull and weapons testing.

Atlantic Hydraulic Systems manufactured the paddles, structural supports and control cabinets for the new wavemaker system.

This hydraulic power unit was designed and manufactured  by Atlantic Hydraulic Systems to be a last chance test system for the thrust vector actuators in the SLS Rocket program. The trailer based hydraulic system is located adjacent from the launchpad for easy connection pre-launch.

Controls and feedback include:

• pump pressure and flow controls
• motor status
• fluid water content and cleanliness
• fluid level and temperature
