RAS files: Frequently Asked Questions

What are RAS files?

A RAS file in the CALS Raster format is a monochrome bitmap image standardized under the U.S. Department of Defense’s Continuous Acquisition and Life-cycle Support (CALS) initiative. Designed for technical documentation, it stores 1-bit raster graphics—typically engineering drawings or scanned schematics—in a simple, resolution-independent structure that preserves fine line detail while keeping file sizes modest. Although now largely superseded by more versatile formats, CALS .ras files remain common in legacy defense and aerospace archives.
