Primary Node 5A
Primary Node 5A is shown here on the deck of the TE SubCom Dependable, with the spare Science Interface Assembly (SIA) installed in the node for testing. Prior to deployment, this SIA will be transferred to the spare primary node frame that is also carried onboard. PN5A, when installed, will have no SIA since it is a placeholder node for potential future expansion.
