City-Ship License and Bactrian Quest (Spoilers!)

How to find the quest for the City-Ship license, and in turn, the Bactrian. Spoilers, obviously!

Intro

I’m putting this up as a guide as a quick and easy to find reference on how to find the quest for the City-Ship license, and in turn, the Bactrian. Forum moderator Amazinite posted this in a discussion thread in 2021, so full credit goes to them – I can take this down on request.

Prerequisites

Originally posted by Amazinite:

The only prerequisites to getting the missions for the city-ship license are the following:
1. Have a combat rating of 5 or higher.
2. Have at least 50 tons of cargo space in your fleet.
3. Have discovered the Hai.
4. Not be in the middle of the main campaign. (i.e. you can't have joined the Free Worlds, or in the future some other faction, but not finished the campaign.) This applies to start all the mission chains needed for the Bactrian. (i.e. if you start a chain of missions then start the main campaign, you could finish that chain without being stopped.)

So long as you meet those requirements, all the relevant missions should be able to offer for you if you're checking various spaceports in the Deep.

Quest Hints (SPOILERS!)

If you're still having trouble, here are all the relevant missions.
1. The Terminus Exploration mission. This will offer on either Memory, Haze, or Nifel. (This involves going to Terminus to salvage a core from a deactivated probe)
2. Deep Convoy missions. These will offer anywhere in the Deep that is within 2 jumps of the Gomeisa system. There are three of them, but only one is required. At the end of these missions they will tell you to do the following point. (You need to escort several freighters across the galaxy from the Deep and back again.)
3. Three "mystery delivery" or "mystery retrieval" jobs from the jobs board.
4. The Mystery Cubes missions. This will offer once you've done at least one of point 2 and finished point 3, and meet prerequisite 1. (This involves visiting many systems and placing cubes in each space port)
5. The Project Hawking mission. This will offer once you've done point 4, and meet prerequisite 2. (Transport scientists from the Deep, pick up equipment from planets in or near The North, return to the Deep)
6. The Deep Remnant missions. This will offer once you've done points 1 and 4, and meet prerequisite 3.
(Guide author's note: I'm not actually sure what this is, other than possibly a follow up from the Terminus Exploration Mission in point 1. I didn't get this mission in my current play through, I think? But I still got the following string of missions in point 7 for the Bactrian license reward)
7. The Scientist Rescue missions. This will offer once you've done points 5 and 6, and is the last string of missions required to gain the city-ship license.

If you still aren't getting anything then odds are you declined an important mission at some point in the past.
