Note: Every ship is organized differently - infact it's not uncommon for the same ship to re-organize divisions, departments, etc. as their mission changes. The Skeleton below may seem "out of whack" to some - but it's the only organiztion I know - it represents the structure of the Proteus from 1973 - 1976. Even the Proteus' structure had changed quite a bit by 1991 - as evidenced by the chart published in the "Operation Fiery Vigil" book. So if it seems that Nav Repair was W3 - instead of W5 - you're probably right - for the time/ship you remember! - just play along with me on this one - I'm too easily confused as it is!!!!
