Components for Underwater Vehicle Applications 

Globe Composite is committed to evaluating, designing, and manufacturing components for a variety of different level submersible applications. Globe has constructed a dedicated clean-room facility to perform the testing and production of high tolerance, submersible-related components. Additionally, Globe Composite has a fully-equipped Quality Control Lab that assesses critical performance measurement requirements, including tolerances and processes, in relation to material and manufacturing. This lab allows our facility and team to serve as a reference laboratory for many of our clients providing UUV, AUV, ROV and other submersible solutions. This is part of the reason the U.S. Navy trusts Globe to deliver over 140 parts and components for submarines.

We have an exceptional level of submersibles experience, ranging from designing to rapid prototyping, to production, and all of the critical testing in between.

How We Help:

  • Corrosion Resistant
  • Hydrolytic Stability
  • Structural Integrity at Extreme Depths
  • Sealing Properties
  • Impact & Shock Resistant
  • Acoustically Transparent Materials

The team at Globe Composite can design and produce a wide variety of submersible components from all or mostly composite-based materials. We can custom blend these materials to exactly meet your product’s specific requirements, so you can rest assured that your part will perform as expected- each and every time. 

Case Study: Nuclear Submarine High Strength Gaskets

Our Durable, Yet Flexible High-Strength Gaskets for Critical Military Systems
When failure means millions of dollars worth of damage, how do you find a solution to your flawed components? Through composites-that’s how. As a major concern to the nuclear submarine fleet, these failing parts would degrade over time causing them to lose the standard needed to meet physical and dimensional requirements.

Globe Composite manufactures gaskets for the U.S. Navy using a specially developed thermoset elastomer named Brandonite® 1200-60A. This flexible, high strength & highly elasticity material was created by Globe Composite to combine:

Submarine Composite Parts
  • High tensile strength and outstanding elasticity
  • Superior resistance to abrasion and tear
  • Excellent energy absorption
  • Low creep and compression set properties
  • High resistance to seawater, oils, chemicals, and UV degradation

Globe Composite developed high-strength gaskets to replace fraying and underperforming missile tube muzzle hatch gaskets made with Buna-N. We formulated a liquid castable, high-strength material that was durable, yet flexible enough to conform to the hatch shape, while assuring a tight-fitting seal at various operating depths.

Case Study: Developing A Recreational Diving Helmet
sub-case-study-2.jpgHow Composites Saved Sub Sea Systems® an Estimated $1.5 Million Over 3 Years

Our client, Sub Sea Systems®, provides recreational diving systems to resorts and aquariums worldwide. for their Sea Trek® tours. This rapidly growing company needed a diving helmet solution that was able to function under submersible pressures, sustain the wear-and-tear of everyday use, and withstand environmental elements.

Prior to the development of a composite-based diving helmet, Sub Sea Systems® was using a handmade helmet that took 40 man-hours of labor to produce. Our cost-effective replacement to fiberglass has greater design flexibility, lowered shipping expense, and increased durability.

Sample Underwater Vehicle Parts

Masts and Electronic Packaging

Masts and Electronic Packaging

Globe designed a unique molding approach that was able to assure precise placement of the electronics package and minimized potential scrap associated with incorrectly encapsulating the wiring and electronics, thereby saving rework and improving the overall hydrodynamics and performance of the mast unit.

    Acoustic Dome

Transducer Covers

We can design and fabricate acoustically transparent covers and metallic/non-metallic hydrophone and transducer baseplates for submersible applications. Our transducer covers can be coated with special anti-fouling materials.

    Precision Gaskets & Seals

Precision Gaskets & Seals

Globe has developed a new family of super high-strength compliant material that is ideal for demanding gasket and sealing applications.  How tough and reliable is this material? It is used as the gaskets for missile hatches on all US Navy submarines. > Learn More


Vibration-Absorbing Isolation Mounts & Thrust Bearings

Vibration-Absorbing Isolation Mounts & Thrust Bearings

Globe can design and manufacture isolation mounts and vibration dampeners for a variety of applications using our advanced, low-durometer, high-strength dampening materials. These dampeners can be bonded to metallic and non-metallic attachment structures or casements such as stainless steel or titanium.

    Mooring and Tethering Systems

Mooring and Tethering Systems

Globe can design and fabricate tethers and mooring system components using our proprietary high-strength elastomeric materials that are ideally suited for the stress and strain associated with commercial mooring systems.

    Monitoring Buoys and Pressure Cases

Monitoring Buoys and Pressure Cases

Replacing stainless steel, Globe Composite manufactures instrumentation cases using impact resistant, rust-proof materials that provide years of indestructible subsea use. This all-composite pressure cases can be made in a variety of sizes to accommodate electronic packages and power sources.


Antenna Housings

Globe has developed durable antenna housing for large defense contractors, using advanced, impact-resistant elastomeric materials.


Acoustic Hull Windows

We can design and manufacture acoustic-transparent hull covers (“windows”) used for oceanographic research. These windows can be made up to 16 feet long and 4 feet wide.


Air Handling Ducting

Globe makes high-tolerance, durable, and flexible air duct systems for the most demanding applications. We can reinforce these flexible ducts with rings made from aluminum or steel to prevent compression. Globe provides critical air handling components on all Virginia-class submarines.
