===Liquid oxygen tank===
The LOX tank is located at the top{{efn|name=orientation}} of the ET and has an [[ogive]] shape to reduce aerodynamic drag and aerothermodynamic heating. The ogive nose section is capped by a flat removable cover plate and a [[nose cone]]. The nose cone consists of a removable conical assembly that serves as an aerodynamic fairing for the propulsion and electrical system components. The foremost element of the nose cone functions as a cast aluminium lightning rod. The LOX tank volume is {{convert|19744|cuft|m3|abbr=on}} at {{cvt|22|psi}} and {{convert|-297|F|K C|abbr=on}} ([[cryogenic]]).

The tank feeds into a {{convert|17|in|mm|abbr=on}} diameter feed line that conveys the liquid oxygen through the intertank, then outside the ET to the aft right-hand ET/orbiter disconnect umbilical. The {{convert|17|in|mm|abbr=on}} diameter feed line permits liquid oxygen to flow at approximately {{cvt|2,787|lb/s}} with the RS-25s operating at 104% or permits a maximum flow of {{cvt|17,592|USgal/min}}.

All loads except aerodynamic loads are transferred from the LOX tank at a bolted, flange-joint interface with the intertank.

The LOX tank also includes an internal slosh baffle and a vortex baffle to dampen fluid slosh. The vortex baffle is mounted over the LOX feed outlet to reduce fluid swirl resulting from slosh and to prevent entrapment of gases in the delivered LOX.
