SWaP
Size, Weight, and Power
What it actually means
The three resource budgets every payload and subsystem fights over, often extended to SWaP-C to add cost. SWaP budgets are allocated early, tracked as technical performance measures, and defended in every design review — because on an aircraft, satellite, or soldier, exceeding any of the three is somebody else's capability deleted.
Where you'll meet it
Subsystem specifications, payload trades, and margin-burn arguments everywhere in aerospace.
