Thanks John,
I did do quiet a lot of reading after my previous post and came across may different OPVs and information but you certainly helped. I found it interesting that the Sea Axe OPV wasn't listed as the 'first' option out of the three due to it's multi-mission capability and the growth room it shows. The site says "Damen Technical Cooperation enables you to build your Damen vessel locally, anywhere in the world. We will provide you with a prefabricated shipbuilding kit and can, on request, combine this with expert assistance, training and backup. By using standardised components it is possible to make a custom-built design, fulfilling any specific local requirements. This cost-efficient technique can be applied to the full range of Damen vessels across a wide variety of marine operations." which seems to provide an easy way to build your own ships locally without the hassle, and that may be something that may help the DoD select it.:
We need to remember that DTR and others are 'assuming' that these are the vessels on offer based on length mainly. All three were sent of to 'refine' their designs as part of the process so you may see something slightly different in the same length and tonnage range when the bids are in.
