If I recall about MEKO, it was more of a physical installation (the modules were built almost like shortened shipping containers with the main component on top (inside contain all the working parts) and could be lifted in or out of a ship by crane. The containers could hold a gun, missile or radar installation. I'd call MEKO crane and play. So, yes, you're right that the concept is not new, just a bit more refined.Plug n Play is not really a new concept in military markets. A German ship builder back in the 60’s was building small warships like that, although they called it “modular”. Might have been Blum und Voss. The design was called MEKO. Weapons systems and electronic systems had differing options for the ordering countries.
