Which feature identifies the MC338 cryogenic liquid cargo tank?

Explanation:
Cryogenic cargo tanks rely on double-wall, vacuum insulation to keep ultra-cold liquids from warming. The MC338 is identified by a tank-within-a-tank design—an inner vessel surrounded by an outer insulated jacket. This nested arrangement is what enables the very low temperatures to be maintained with minimized heat transfer, and it’s the feature you’d look for to distinguish MC338 from other tank types. Paint color, door count, or mnemonic cues aren’t reliable identifiers, whereas the presence of a tank inside a tank directly signals the MC338 configuration.
