In about 1978, we developed an attack profile against the West Raynham Bloodhound site. Follow the bomb steer, then when locked, break at 60° AoB through 90° to beam the CW illumination, reverse to hold it on the beam following the AEO's calls until it broke lock. Meanwhile the Nav Rad continued to keep the target in view. Once the lock broke, turn back at 60° AoB onto the bomb steer for another 10s or thereabouts until illuminated again. Keep up the process until inside the min. engagement range, then complete the bomb run.
Just been digging through the 85 Sqn F540's from the period and the fact that that your tactic worked is commented on.
