Gahh. Already just barely into my coverage of the Antares class Surveyor and already I’ve hit a brick wall – sensor ranges.
1 Parsec (3.27 light years) is implied to be the maximum sensor range of the Constitution Class in TOS (courtesy of Memory Alpha) and the TNG Technical Manual gives a maximum sensor range figure of 17 light years for the Galaxy class. None of the reference material I have nor anything I’ve found online has been able to give an even hypothetical figure for any other ship class.
Really, this isn’t too big of a deal. Antares is the only TOS Surveyor/Science Vessel I plan on doing and the only other class where a specific figure would be relevant is Akula (as a Scout/Early Warning platform). Nevertheless, going forward, I feel that establishing some broad era-specific ranges might be helpful.
TOS: 1.5LY (Daedalus) – 5.5LY (Federation)
The Federation class DN is the largest and most powerful ship of the era, so obviously, it will take the spot at the top. With Constitution at 3.27LY, I think a range of 3.85 for Pyotr Velikiy, 4.3 for Akula (appropriate, given its mission) and 4.8 for Antares works out well, leaving plenty of wiggle room should I decide to get more detailed with other classes.
TMP: 6.0LY (La Fayette) – 12.3LY (Arizona)
Moving into the Linear Warp era is all about new technologies and more power. Though La Fayette comes in later as a design that uses clear Excelsior aesthetics, I’m pretty sure this is the smallest one I’ve come up with in this era. Arizona on the other hand is the largest and I think 12.3 is a good range that leaves plenty of room to move into the Lost Era and then TNG proper. I’ll peg Oberth at 8.0 owing to the ‘basic’ design and small size, Enterprise at 9.4, Tikopai (the large exploratory/scientificly focused one-off) at 9.8, Akula II at 10.3 and Excelsior at 11.5
TNG: 16.0 (Nebula-std), 17.0 (Galaxy)
The various Lost Era designs can stay close together I think, say between 13 and 15LY or somewhere in that area. From TNG forward then, Galaxy and Nebula will be the baselines and all ships from that point forward, even smaller ones like Intrepid will jump from there (specialized ones like Akira or Steamrunner could possible exceed Galaxy/Nebula figures as well………..like I said though, mentioning them isn’t going to be relevant to *every* class)
