The tender specifies a range of 6,450 nautical miles at 16 knots (Endeavour has a range of 10,000 nautical miles and can attain 14 knots) and requires the new ship to spend up to 160 days at sea each year and 60 days alongside...
The Dutch liked their new ship too much. From Wikipedia:
"On 24 April 2015 JLSS Karel Doorman was formally commissioned and hence forward 'HNLMS Karel Doorman', pennant A833. Seen on May 25th on the St. Lawrence River, in front of Baie-St-Paul (QC), Canada, navigating upstream. She also stopped at the Montreal Old Port May 26th, 2015."
Didnt realise that ship actually replaced 2 oilers as well as having the amphibious support. I think it also has a hospital and space for fleet command, so its very multipurpose. Not sure I would want all that on a replenishment ship, but definitely the hospital makes sense because casualties would want to head back to base after the replenishment.
