Partly correct but not relevant or responsive.
I might have been more careful and made the point that in an engagement where I need HOBS, I am more than likely in mutual detection range (particularly as nose-on RCS is not the issue). Hence the transient RCS increase caused by missile rail extension is acceptable, and not equivalent to the throughout-the-mission RCS increase caused by external weapons.
As for guns: I'd like to see what target RCS, at relevant aspects, is required to disappear from a fighter-type radar at <2000 meters. I would suggest that it's a whole
load of - dbsm.
