Specifications very scarce at this stage from what I can gather, but a new, much larger 'Vigilance-100' design by VARD has emerged for the Canadian 'Continental Defence Corvette' program to replace their 'Kingston class 'coastal defence vessels'. I understand this is a R.A.N forum but we speculate about foreign OPV designs all the time, in particular as of late, the forthcoming large, low-crew JMSDF design.
An older article somewhat detailing the 'Vigilance-75' flight I & II designs to illustrate how the design has evolved over time, presumably from continuing input from the RCN. Even this was a promising design for a ship presumably a little smaller than the Arafura class.
The Vigilance concept continues a long line of waiting for something that won't exist
