Sustainment Resource Hub
Sustainment is no longer just about managing obsolescence—it’s about recognizing that obsolescence happens, and developing better ways to respond. Ten years ago, pre-stocking was the only real tool in the toolbox. Today, lifecycle assurance, sustainment engineering, and new sources of supply are reshaping how embedded systems stay mission-ready for the long haul.
At GDCA, we’ve spent decades building that shift—helping programs move from reaction to resilience. This Resource Hub brings together insights, strategies, and tools for navigating embedded sustainment in the real world. Whether you're new to the space or looking to sharpen your approach, you'll find practical guidance and field-tested insights here.

Product End-of-Life Strategy: How to Know When It’s Time to Exit
Not every product belongs on your roadmap forever. For embedded OEMs, developing a product end-of-life strategy can be complicated. The decision to exit a legacy product is rarely straightforward. It’s…
The Quarterly Review of Legacy System Sustainment: Who Owns the Knowledge?
As the summer comes to a close and we head into the fourth quarter, Tania Scroggie, Director of OEM Relations at GDCA, Inc., returns with another installment of her Youtube…
You Don’t Need a Redesign — You Need a Legacy System Sustainment Plan
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…

A quiet erosion that often ends in a sudden catastrophe. The risk isn’t always a single, dramatic event; it can be 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.
Can redesign alone solve legacy risk? Thomas Helmonds explores why engineering isn’t always the answer and how a strategic sustainment approach can reduce lifecycle costs, preserve mission readiness, and extend the life of critical systems. U.S. Tech — July 2026 Edition – Page 24
BOHEMIA, New York and LIVERMORE, Calif. Rugged embedded computing supplier North Atlantic Industries (NAI) and long-term embedded support provider GDCA Inc. announced the successful transfer of NAI’s venerable 64C1 & 64D1 legacy product lines, renowned for their reliability and longstanding service to the U.S. Navy, to GDCA.

Proactive management in all phases of a life cycle is crucial to avoid costly component replacements, ensure critical weapons system readiness, and reduce risks to warfighters.
When it is understood that traditional obsolescence management itself often starts too late in a program’s life cycle, we see the need to address ongoing risk from a different angle.
