Explaining SWaP and SWaP-C2 Principles

In computing, SWAP and SWAP-C2 are acronyms that stand for Size, Weight, and Power. It’s a design principle championed by the US Military and NASA to produce small, light computing solutions that minimize power usage.

The original acronym, SWaP, focuses on achieving the lightest, most powerful systems in the smallest footprint without compromising performance. And since it’s estimated that reducing an Intelligence, Surveillance, and Reconnaissance mission platform by one pound saves $30,000, you can understand why this is so important.

But, as embedded systems shrunk to meet SWaP characteristics, thermal management concerns and costs increased–so cost and cooling were added to the acronym, forming SWAP-C2.

So, at Sealevel, how do we address the cooling aspect? We’ve found it’s best to incorporate heat sinks or pipes and use mechanical enclosures made from conductive materials to manage heat. These thermal management techniques are preferred over fans, which increase the opportunity of failure.

And from a cost standpoint, we’re always working closely with our partners to stay on top of supply roadmaps to ensure availability, meet budget expectations, and manage obsolescence.
