The boundary
Nothing Crosses the Interface but Structure.
Carriers, Not Munitions.
The joint carries load in one direction and nothing else in any direction: no power, no signal, nothing to arm. That is the boundary between a carrier and a munition, drawn in hardware.
The register, the shoulder and the three bayonet lugs carry the launch load into whichever head is mounted, and that is all they carry. There is no pin, no contact and no channel through the joint for power or for a signal. No electrical conductor is routed through the nose interface, and that is a description of the round rather than a caution against a mistake: there is nowhere for a conductor to go. Goose CS-110 has no wiring harness because it has no electrical system to wire, and the interface every head shares is built to the same rule: structure crosses it, and nothing else does.
That is the doctrine this whole line is built to, stated at the one joint where it would first be broken if it were ever going to be. No warhead, no fuze, no energetic material of any kind crosses this interface or sits behind it, on any head this family builds. Every product on this page is a carrier. None of them operates a weapon.
DoctrineCarriers, not munitions. Nothing that operates a weapon crosses this joint.
The rule is a property of the hardware, not a policy on top of it: there is no power path and no signal path through the interface for anything to use.
