We Build Parts According to Spec

Globe works side-by-side with you to design and manufacture the parts you are looking for according to rigid specifications. While we are a relatively small business, we are robust enough to provide a full suite of Design, Engineering and Production capabilities, and flexible enough to work on both a small or large volume basis.

We have years of experience delivering the highest quality results for the Navy, and have particular expertise in: Reducing Acoustic Signature, Corrosion Resistant Materials, Hydrolytic Stability Parts, Structural Integrity at Extreme Depths, Sealing Properties, and Impact & Shock Resistant Parts.


Why Choose Globe?

  • Defense Experience
  • Design & Develop with you
  • Helps Develop New Technology
  • Enhance Existing Performance
  • Removes Program Risk
  • Full Testing Capabilities
  • Metallic & Non-Metallic Parts

We Engineer Parts When Specs are Missing

Globe can manufacture both metallic and non-metallic parts according to specifications, however we also specialize in recreating existing hard to find parts. In cases where the original manufacturer cannot be found, or the original specifications no longer readily exist, Globe's engineering team can recreate design specs and manufacture the missing parts. Our re-engineered parts often use composite materials, so our replacement parts may show significant improvement over the effectiveness and durability of the original parts!

We Assist in Developing New Technology

Submarine Builder Recognition Plaque Globe's engineers and material developers have many years of deep experience researching and finding new solutions. Our team is available to assist research labs looking into a wide variety of component possibilities.  

We Provide Full Quality Testing Services

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 can assess 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 submersible clients.

We Work to Certified Military Standards

Globe was certified as a MIL-SPEC 45208A manufacturer by the U.S. Government through our extensive experience working to military specifications. Our certifications also include: ISO 9001-2015EB2678, and NAV 12 & 15. In addition, Globe routinely works to the following quality standards:

  • MIL-I-45208A Inspection
  • MIL-Q-9858A Quality Program Requirements
  • MIL-C-45662A Calibration System Requirements
  • MIL-STD-271F Non-Destructive Testing Requirements
  • MIL-R-6855 Synthetic Rubber
  • MIL-R-9300 Glass Cloth Based Plastic Laminates
  • MIL-G-21610 Synthetic Rubber Heat Exchanger Gaskets

Sample Defense Products 


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.

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.


Composite Gaskets

Our specially formulated gaskets, based on our Defense technology products, last three times longer than traditional foam or urethane gaskets. They combine the properties of high tensile strength & elongation, outstanding elasticity, and excellent resistance to seawater, oils, chemicals, and UV degradation. 


Buoyancy Assemblies

Our low density syntactic foams, in combination with our wealth of design experience and value-added capabilities ensure optimal syntactic performance even under significant hydrostatic pressures. Quick-turn buoyancy packages are also available. These packages are fully machined to shape and include protective skins and coatings, as well as inserts for attachment to a vehicle or auxiliary equipment. > Learn More


Structural Materials

The impressive mechanical properties syntactic foam provide strength, structural integrity, thermal protection and resistance to water absorption, at a significantly lower weight per volume than most traditional materials. This makes syntactic materials the ideal solution for many Defense applications. > 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.


Antenna Housings

Globe has developed durable antenna housing for a large defense contractor, 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.



Syntactic Void Filler

Specially engineered and formulated to serve as void filler for Submarine / subsea applications, these syntactic materials are provided as multi-part kits that are mixed and poured into any free-flood cavity or void. Void spaces in both steel or composite structures may be filled with syntactic to fine tune ballast capability, reduce in-water weight of large components during deployment or simply to reduce corrosion.

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.
