Found a somewhat old snippet of a tender document related to Astra Mk 2 on another forum confirming the outer diameter of Astra Mk 2 to be 190 mm compared to 178mm of Astra Mk 1
And according to Alpha Defence The Astra Mk2 missile’s two pulses are separated with EDPM rubber with kevlar fillers, with the second pulse having a higher burn rate than the first. This enables the missile to maneuver more aggressively during end game, enhancing its targeting capabilities. The weight of the missile system is kept low, with pulse 1 weighing 40.1kg and pulse 2 weighing 20kg.
