When Sea Dart entered service there seemed to be confusion over the warhead type, there being statements that it was a fragmentation round, or an 'externally grooved fragmentation warhead', and one former colleague who worked on the missile confidentially told me that it was a continuous rod warhead but made of Terylene rather than steel. I have been able to establish that Sea Dart carried the K27A1 continuous rod warhead with conventional steel rods. Oddly enough the warhead did contain Terylene, as a binder for the TNT/RDX mix.
