Forums: Index > Watercooler > T5 Starship Mission Codes

This is the list of the ship mission codes from the T5.10 book (book 2, p. 68), but organized differently. The purpose of this is to take another attempt to reconcile the wiki Ship Classification (and Starship-Nav-Bar-Two-2019CE) with the T5.10 mission codes. This is a request to make sure the T5.10 codes are propagated forward.

The T5 mission taxonomy is included where it clarifies the mission code.

  • Nomenclature. One productive pattern appears to be <secondary Code 1> <secondary Code 2> <mission Code 3>, where Code 1 + Code 3 represents a subtype, and Code 1 + Code 2 + Code 3 the sub-subtype. Example: Boat > System Boat > System Defense Boat.
  • BCS ships. Since all capital ships are principal military vessels, they are commonly talked about via their secondary codes only, omitting the ubiquitous "Cruiser" type (this potentially holds for Frigate BCS as well, assuming they exist). Thus most capital ships are Battle Cruisers. They are further divided into subcategories: Battle Beam Cruisers, Battle Strike Cruisers, and so on.
  • Mission Modifiers. Rob suggests that the mission modifiers represent an "open class", and can be freely added to satisfy ships that don't have T5 codes. See the secondary modifier table for suggestions.

BCS Codes[edit]

BCS codes follow an informal nomenclature. Commonly, they are only referred to by their secondary codes, with the main code omitted. Presumably the main code is known so well or so common that it's assumed by the source.

Wiki-1 Discussion[edit]

Ship Mission Code/updates is the lengthy discussion for the first set of Wiki specific mission codes. These were developed within the wiki to capture the missing and forgotten types from the CT and MT ship mission codes. These were produced in 2015 prior to the T5.10 rules. For any new updates, the linked page could be referenced to make sure we're covering everything. Tjoneslo (talk) 19:01, 17 March 2022 (EDT)

Wiki-2 Amendment Discussion Starters[edit]

I see that a lot of work went into the Wiki-2 column, so I want to start talking over the decisions made there.

In particular, I want to see how many of these are intractable, and how Wiki-2 sifted through the ship types that "fall through the cracks". Rje (talk) 17:36, 17 March 2022 (EDT)

One of the concerns around the T5.10 mission codes is they seem to be focused on the ACS class of small ships, and there may be a different codes for the BCS or larger classes. Tjoneslo (talk) 19:01, 17 March 2022 (EDT)
T5 is definitely ACS-focused, and AOTI sure makes it look like the two are different. But maybe we can work it out. Rje (talk) 00:18, 19 March 2022 (EDT)
I figured it out. The ships in AOTI are talked about commonly by their secondary modifiers only: the main code is elided. Formally, however, it is part of the ship's code. Rje (talk) 00:27, 19 March 2022 (EDT)

Rob's Preferences[edit]

Since I've decided that the mission code is not exclusive to its table taxonomy, I prefer to simply present the bare codes, and allow an open class of secondary modifier codes (a) to clarify, and (b) to allow for "edge" ship types we haven't thought up.
