Navantia are touting a LHD / LHA, LPD / LSD or an LPA /LKA13,000 tonne in the Athlas Family. If we went down the LHD track there would be commonality with the RAN and from what I read it also can do AOR. So since Endeavour would be the first replacement then this could be well worth looking at. When Canterbury is due to be replaced then a second vessel would be ordered. We would then have two vessels with commonality and the associated benefits with the RAN operating similar vessels. It is half the size again of the Canterbury but in the long run I think that if two 13,000 Navantia LHDs were bought for the RNZN then in the long term it would be money well spent giving NZDF very good capability for the JATF.Navantia have a smaller version of the Juan Carlos/Canberra Class LHD, IIRC, around the 180-190 mark, 15-17,000 ? No ski jump and still has the well dock. Im sure Spain would do a very good deal on that ? and would also have supply chain commonality with the RAN LHD's.
This is the Navantia paper on its amphibious warfare ships. 85 pages but a good read. http://infodefensa.com/wp-content/uploads/JCI_en_v2.pdf
