Hi, regarding the Shrike vs SA6 with the A4
I can confirm it does, however with "historic" accuracy and results. I've found that the real launch parameters seem to be right (get in under 10 miles and accurate boresight of no more than 3-5deg variance and fire both)
This should net a PK of about 20% , which appears to be very much inline with historical references. (Note actually hitting the target dead on is even lower, if you watch the impacts they tend to be within a few meters)
Growling Sidewinder ran a excellent eval on this subject ref:
DCS: A4E Skyhawk AGM-45 SHRIKE Utilization + Test
As a historical ref: AAEE tests for the RAF Black Buck missions in Falklands suggested "for a PK of 0.9, you will need to get within 6 miles and fire two in quick succession" (from the book Vulcan Boys)
Good luck
