Fortunately that suicidal technique had been binned by the time I flew the Vulcan (1977); the only attack option we used was low-level laydown.
Did that mean flying over the target, in range of any weapon available? I know the recent GW1 thread highlighted that GR1s overflying the target with JP233 actually had better survival than those lofting bombs further out, but they were a lot smaller than a Vulcan.
I guess it was not the preferred attack method, but without a standoff weapon like Blue Steel and Skybolt we didn't have many options and high level had been proven to be dangerous?
Were there any estimates on success rates for low-level laydown V's loft or was it largely irrelevant as it would have effectively been end ex for everyone?
It sounds like the SSBNs were our only credible strategic response after the late 60's.
