No research table will ever show this blueprint. The row marks the module not researchable, so its Level 3 recipe stays locked and every module on a server came out of a crate, as its item page says. The calculator prices what you are holding: a handful of frags and four pieces of tech trash.
The tech trash is what makes it a real decision. While your group still plans to take the MLRS, keep the module with the raid gear: without it the truck never aims, and a box of MLRS rockets is only pipes and powder. Once nobody will run that monument this wipe, the ordinary recycler gives back two tech trash and some frags. Two is exactly what one C4 asks for.
Looking for the gun part that pings targets to your team? That is the targeting attachment, a cheaper Level 2 craft with a blueprint you can learn.
