UNDERSEA SYSTEMS INTERNATIONAL, INC.

Undersea Systems International, Inc. specializes in the design, manufacture, and maintenance of mission-critical underwater communications and audio equipment for defense and homeland security applications. Their technical expertise centers on diver transceivers, bone conduction audio systems such as the BP-45 Bone Phone, specialized headset-microphone assemblies, and ruggedized cable systems engineered for harsh marine environments. The company excels in precision electronics manufacturing and field repair of embedded communication devices, demonstrating deep proficiency in analog and digital signal transmission, waterproofing, and low-power wireless interfaces tailored for submerged and high-noise operational contexts. Their ability to deliver both new hardware and rapid repair services for specialized diving equipment sets them apart as a trusted provider of survivable, mission-essential comms for tactical underwater operations. The contractor maintains a strong, consistent relationship with the Department of Defense, delivering advanced diving communication systems and associated electronics that support special operations, naval diving units, and underwater reconnaissance missions. A single award from the Department of Homeland Security indicates targeted support for maritime security and port protection initiatives, suggesting a niche role in border and coastal surveillance technologies. Their primary industry focus lies in communications equipment manufacturing under NAICS 334290 and audio equipment production under 334310, with supplementary work in wiring devices and precision repair. This positions them as a specialized supplier within the defense electronics supply chain, serving the unique demands of underwater and extreme-environment communication systems rather than commercial or general-purpose markets. Undersea Systems International, Inc. is a small business based in Santa Ana, California, with no federal certifications on record. Their geographic footprint is centered on Southern California’s defense electronics ecosystem, leveraging proximity to naval and special operations command centers to enable rapid prototyping, testing, and sustainment support.
