ITS-S6 and ITS-P6 (Integrated Truss Structure) are elements of the International Space Stations main truss structure.

The Integrated Truss Structure of the ISS consists of a linearly arranged sequence of connected trusses which is used to mount various unpressurized components, such as ELC logistics carriers, radiators, solar arrays, and other equipment.

The P6 and S6 segments photovoltaic Modules (PVM) include the two Solar Array Wings (SAW) and the Photovoltaic Radiator (PVR).

The P6 truss was launched on STS-97 in December 2000. P6 was originally mounted to the Z1 truss. Shuttle mission STS-120 in October 2007 detached the P6 truss from Z1, remounted it on the P5 truss, redeployed its radiator panels and redeployed its SAWs, although with some difficulties.

S6 truss was launched on STS-119 in March 2009.
