You Don’t Need a Redesign — You Need a Legacy System Sustainment Plan
August 12, 2026
When aging systems become difficult to support, redesign often feels like the obvious solution. Components become obsolete. Supply chains become unstable. Repair demand increases. Engineering teams spend more time supporting systems that were designed decades ago. Eventually, the conversation shifts toward replacement: Wouldn’t it be easier to redesign the system and start over? Sometimes, yes.…
Legacy Sustainment In-House: Hidden Risk for Embedded OEMs
February 9, 2026
What Happens When Embedded OEMs Keep Legacy Sustainment In-House? A quiet erosion that often ends in a sudden catastrophe. The risk isn’t always a single, dramatic event; it’s a slow, silent drift. Systems degrade. Critical knowledge walks out the door. Customers grow frustrated. And leadership is often unaware of just how fragile their internal support has become until it’s too late. …
Planning for Legacy Sustainment Isn’t Optional — It’s a Business Decision You’re Already Making
February 3, 2026
The Cost of Waiting: Why Legacy Failures Are Always More Expensive Later Legacy systems rarely fail all at once. They fail quietly—and expensively. A component reaches end-of-life. A supplier exits the market. Test capability erodes as documentation ages and people move on. None of it feels urgent in isolation. But together, these small degradations create something far…
Legacy Sustainment Magic: When OEMs and LEMs Come Together (Sea Sparrow Case Study) – GDCA
February 26, 2025
GDCA is in the business of helping defense programs who can no longer get support for obsolete electronics circuit cards, like computer boards, graphics cards, power supply controllers and many more specialized electronics assemblies that make defense systems “smart”. These circuit card assemblies (CCAs) are often commercial products that have been discontinued by their OEMs.…
Legacy Engineering: Balancing Innovation with Tradition
October 1, 2024
Legacy electronic systems result from technology’s swift evolution, a rapid pace of growth and innovation that, while widely celebrated, leaves many embedded systems incompatible and unable to easily and affordably upgrade in its wake. What is Legacy Engineering? The goal of engineering as a general field has always been to solve technical problems, increase efficiency…
Just because you have the TDP doesn’t mean you can build the board
February 20, 2024
Recently, one of the ways in which we’ve seen end-use customers try to combat electronics obsolescence is by getting the technical data (TDP) of the required circuit board from the OEM. For the last few years, there has been a growing conviction that having the TDP is the answer to the challenge of assuring support…

How to Source Discontinued Embedded Boards
September 1, 2023
Finding embedded circuit boards after the OEM has discontinued them can be challenging, especially if the board is several years old. However, there are several comprehensive steps that you can take to source the discontinued boards that could save you time and money. Specific sources have risks, so always consider your applications’ security, safety, and…
You Get What You Pay For
August 2, 2023
The value of working with an ITAR compliant company ITAR or the International Traffic in Arms Regulations, is a vital set of regulations that control the export and import of defense and space-related articles, services, and technical data on the United States Munitions List (USML). Every company that handles, manufactures, designs, sells, or distributes items…
The Human Factor: When losing older workers leads to obsolescence
April 10, 2023
Ask anyone who drives an older car. As the system ages, it develops its own quirks. You have to jiggle the shifter in park to get the keys out of the ignition. You have to pump the gas twice before it starts up on a cold day. The AC has to be turned off…
