Weight Classification Systems
As noted on the Background page, the primary weight data collected on this site falls into one of three main categaries;
- BSCI (Bureau of Ships Consolidated Index) [older USN and related navies]
- SWBS/ESWBS (Ship Work Breakdown Structure/Expanded Ship Work Brekdown Structure) [modern USN and related navies]
- NES (Naval Engineering Standards) [RN and related navies]
- Group 1 being the structural weights
- Group 2 being the main propulsion weights
- Group 3 being the electrical system weights
- Group 4 being the "electronics" weights (including Command, Control, Communications, Computers, Intelligence Systems, SONARS and RADARs, etc)
- Group 5 being the auxiliary systems weights
- Group 6 being the outfit and furnishings weights
- Group 7 being the weapon systems weights
In all three systems, these high level weight groups can be broken down to the lower level categories that make up that total weight group. For example,
- Single digit, two digit, and three digit summaries of these weight categorization methods are summarized below
ESWBS/SWBS
The table below summarizes the single digit, two digit, and three digit weight categories in the ESWBS/SWBS systems.
