Defense: Naval Forces

Over the past 35 years, Sealevel has developed and manufactured serial communications, digital I/O, and rugged computing products that are trusted by every major U.S. and Allied nations military contractors. Our computing and communications solutions are designed to stand up to the harshest environments. Choose from an array of COTS products or partner with us to create a custom solution ideally suited for any naval force application.

Rugged and Reliable Solutions for Naval Forces

Deterring maritime threats and maintaining freedom of the seas demands rugged, intuitive equipment that naval forces can utilize quickly and efficiently. Solutions must be adaptable and easily understood. For more than 35 years, we have been designing and manufacturing serial communications, digital I/O, and rugged computing products that meet – and exceed – the most stringent military standards.

We have a wide range of COTS, ready-to-ship products, and our engineering department has the experience to custom design solutions to meet any I/O or computing problem naval forces may encounter. We have consistently provided innovative, intuitive hardware and software products enabling computer connectivity and control to nearly every major US and Allied military contractor, including Northrop Grumman, Raytheon, BAE, Boeing, L3Harris, General Dynamics, NAVWAR, NAVAIR and SOCOM.

COTS Synchronous Serial Solutions

Sealevel offers the widest selection of synchronous serial choices for radio, radar, telemetry and other data intensive applications, and are trusted where high-speed communications are required. All Sealevel synchronous serial products are engineered with strict attention to timing to achieve the most reliable high-speed communication possible.

Rugged Embedded Computing

Designed for I/O-intensive applications, our industrial computerstouch panel PCs and COM Express solutions offer unmatched computing power combined with the flexibility and configurability required for naval application, requiring no fans or other rotating parts. We design computers that meet – and often exceed – the most stringent requirements, including, but not limited to MIL-STD-901, MIL-STD-810, and MIL-STD-461.


Sealevel offers an alternative for implementing MIL-STD-1553 using software IP cores integrated into FPGA devices. IP cores provide substantial advantages over standard 1553 ICs including reduced cost, easy ability to upgrade, small board footprint, easy evaluation, and it supports long product life cycle. This allows us to offer a wide variety of MIL-STD-1553 COTS expansions.

Sealevel Expertise

Sealevel has more than 35 years of experience designing and manufacturing serial communications, digital I/O, and rugged computing products that are trusted by commercial customers, military & governmental customers, and OEMs.

Serial I/O

Sealevel offers the widest selection of synchronous serial choices for radio, radar, telemetry and other data intensive naval applications. Our serial adapters are trusted for military, aerospace, and commercial applications where reliable, high-speed communications are required. These interfaces support RS-232, RS-422, RS-485, and RS-530 electrical interface standards and offer a traditional bus-based approach as well as USB and Ethernet solutions.

Embedded Computing

Sealevel embedded computers and touch panel PCs combine the advantage of COTS and custom development to provide ruggedized computer solutions to meet and exceed any requirements for naval application. Ideal for installation in armored vehicles, for controls in remote workstations, and electronic warfare subsystems, these computers are designed to operate reliably in extreme conditions.


Sealevel’s MIL-STD-1553 board-level products, IP cores and custom computer designs are specifically engineered for military, avionic, and aerospace applications. By using software IP cores integrated into FPGA devices, we are able to offer substantial advantages over standards 1553 ICs including reduced cost, easy upgrade ability, small footprint, easy evaluation, and a long product life cycle.

Digital & Analog I/O

Monitor and control real-world signals with any computer using Sealevel digital and analog I/O products. Our digital I/O products are used in a variety of naval applications, including command and control networks for naval flight decks. Select from field-proven optically isolated in puts, Reed and Form C relay outputs, TTL interfaces to solid-state relays, A/D and D/A functionality.
