How long does a O2 Tank last.

[Survivor12]

I'm trying to build fighter ships with O2 but have no idea how many minutes a full tank lasts?

They should give cockpits a built in oxygen storage. Maybe not as much as the actual tank, but requiring the tank for any oxygen at all is ridiculous.

if i remember correctly a large grid oxygen tank lasts for roughly 18 days under the consumption of one person, while small grid oxygen tanks last for half that, and oxygen canisters (player item) last for 26 or so minutes and the in-suit oxygen storage lasts for roughly 15 minutes, i believe its pretty balanced considering space suits have to accomodate comms systems, computers, heating/cooling systems and life-support systems, 15 minutes on a suit is ok, in fact it should be even less when in a gravity field of 1G since space suits weigh a lot on earth-like planets and would exhaust the user even with servo-assist

Comparing real-time duration to the in-game length of tanks doesn't work due to the games default passage of time- whats the default duration for an in-game day, 2 or 4 hours?

By that comparision a single tank is lasting your character well beyond real world figures. Its practically impossible to run out of O2 so long as you're able to construct extra bottles.
