Interesting. I gather some marks of Royal Navy Sea Kings have ANR, whilst the Royal Air Force doesn't consider it neccessary in their Mk 3 SAR cabs!
Maybe the cost of ANR is more than the anticpated cost of future claims.
I can confirm that one variant of RAF C130 has ANR and the other doesn't.
What I can't find is the documentary evidence that supports the widely rumoured inception costs versus compensation cost decision to use one without ANR.
