Not that this matters for the topic, but I don't see why people have started saying "weapons system" instead of "weapon".
I think ultimately it's a consequence of weapons manufacturers in the US is trying to make their products sound more impressive, and in general military terminology is a huge nonsensical mess.
Just consider that "self propelled gun" and "main battle tank" are very different things despite the first being a quite accurate description of what the latter consists of. Or the distinction between a cruise missile and a one way drone...
Guns, swords, and bombs are weapons. The same, attached to fancy computers that can use them autonomously are weapon systems. At least that's how I've always hears the terms used.
Guided missile launchers are weapons systems, because the projectile and the launcher each are a component of a complete system which requires significant technology. This is in contrast to a firearm, which has all of the technology in the gun and not the ammunition (for the most part) or more simply a knife or sword.
It's a "weapon system" when there is a computer that runs various aspects of the weapon.
It’s a bit silly for this situation, but the basic idea of moving from “weapon” to “weapon system” is reasonable, in a 20th century kind of way.
Basically, WWII showed planners they were in the war business not in the ship/plane/tank business. Take navies, for example. For most of the history of the professional navy, the overwhelming cognitive container for “unit in the navy” was a ship. Planners paid for ships to be laid down, admirals planned where they went and captains were responsible for them in all regards. You could reasonable count a navy’s capability by counting the kind and number of their ships: thus and such frigates, ships of the line, etc. However, even before the 20th century naval planners knew and acted like ships weren’t atomic: counting guns on ships of the line as a distinguishing feature or planning a sortie based on available marines both herald what would come later. But mostly we thought of ships as ships. If the enemy was to have 3 battlecruisers then we ought to have 4.
WWII shuffled all that around. At the scale of fighting and industrial demand, the idea of a “ship” or a “tank” or a “fighter” as a unit of analysis started to look tenuous. Successful commanders and (especially) planners noticed that the math worked out much better if we considered units of analysis larger than individual technological objects. The immediate consequence is one starts to think in terms of weapons delivery to the enemy and not the Sherman tank. The primary concerns then (often but not always) shift from characteristics of the weapon as a weapon to: can this system as a collective be built cheaply, can it be deployed + trained on easily, and can it achieve goals in mixed employment.
The same basic idea animated the operations research revolution in warfare, the bam changes from thing to thing_system or thing_platform are consequences of that.
Nobody has started saying weapon systems instead of weapon. Its just precise terminology.
