Notes
- The secondary missions such as Ice Mine, Cyclops Array, or Freight Linker provide rewards from the "abandoned derelict" drop table (i.e. the Nautilus parts). See "Second Cache" under Neptune Proxima's Caches in Empyrean/Rewards.
- Note that The secondary mission is not always present.
Trivia
- The Nautilus is named after the real-life cephalopod of the same name, known for their distinctive spiral shaped shells. With the sentinel's wings retracted, it vaguely resembles the same shape.
Nautilus Prime is the Primed version of the Nautilus Sentinel, sporting higher Shields and Armor, and is pre-equipped with the enhanced 
Verglas Prime. Nautilus Prime was released alongside 
Sevagoth Prime and 
Epitaph Prime.

Update 34.0 (2023-10-18)
- COMPANION STAT CHANGES
Two broad changes have been made with regard to your Companion's base stats to increase their staying power:
1. Health, Shields and Armor have been refactored across the board.
This simple numeric buff was made with the goal of increasing Companion survivability. This also means that the choice of whether to use, for example, Enhanced Vitality or Linked Vitality, will depend on your Warframe choice instead of the Linked Mod always being strictly superior.
2. Non-Sentinel Companions now gain their full Health and Shield values immediately when you acquire them.
Historically Health and Shield values would increase as your Companion ranked up, which you could see as "Rank Bonuses" in the Upgrades screen. We've removed this behavior and simply given Companions what would end up being their Rank 30 values at Rank 0. This should let you immediately take your Companions on more difficult missions after earning them!
Including both the removal of Companion Rank bonuses, and the base increase to stats, the following lists the stat changes for all Companions at Rank 0:
Revised Sentinel Stats:
- Nautilus: 560 Health (from 200), 250 Shield (from 100), 80 Armor (from 50)
Hotfix 33.0.4 (2023-05-02)
- Fixed Nautilus missing its incapacitated animations.
Update 33.0 (2023-04-26)
- Fixed being unable to chat link Nautilus components.
Hotfix 30.1.1 (2021-05-05)
- Added the Nautilus Blueprint and Components to Rotation B and C of Corpus Railjack Defense on Neptune. This was added to give endless-mission minded players a way to acquire the Sentinel without having to only do non-endless missions.
Hotfix 30.0.8 (2021-04-27)
- Fixed a progression stopper in The War Within Quest if you have a Nautilus equipped during the ‘Purge Precept’ phase. As reported here: https://forums.warframe.com/topic/1255508-quest-the-war-within-kepping-getting-killed-by-nautilus/
Hotfix 29.10.3 (2021-03-23)
- Fixed inability to Trade the Nautilus Blueprint.
Update 29.10 (2021-03-19)
