Jeepys - I can only go on what Bristow were showcasing on their roadshows for the managed transition - where most of the SAR kit was shoved down the tail (sorry accessed when required from the special SAR equipment storage area).
I would have gone for a full S92 fleet but, as sumpor stylee has said, that wasn't allowed so we have a re-imagined SAR helicopter called the 189 - which isn't actually certified in the SAR role yet is supposed to be online in several bases next year.
This must be costing Bristow money already as they have had to train crews on S92 who were destined for the 189 - they will then have to convert again when the aircraft becomes available.
