Range of operating temperatures?

Question: What is the range of water temperatures in which the Trident can operate? Could it be deployed in Arctic waters? What about a hydrothermal river? I really need to know what’s the hottest temperature water a Trident can operate in?

Trident has been tested in water right at the freezing point (around -2C in seawater) and as high as around 40C. It is likely that the vehicle can handle even warmer temperatures than that, but that has not been tested to my knowledge. At particularly high temperatures, the depth capability of Trident may be reduced, and in very cold conditions battery life will be lower. Sounds like you’re planning to do some interesting work!
