Official Sea Trials on a CV/CVN, aka boat, have not been executed for the V-22 prior to now. Sea Trials involves a syllabus of KPPs; Key Performance Parameters. The first boat to conduct Sea Trials for the Osprey was the Wasp in December of 1990. The second boat to conduct Sea Trials for the Osprey was the Saipan in January of 1999. Wasp is a LHD. Saipan is a LHA. Just landing on the deck of a CV/CVN doesn’t constitute executing Sea Trials.
OK. What we did in the '90s were called "Proof of concept". We just trying to sell the darn thing!
