Flagship is singular Many states have two or more excellent state universities often one may exceed the other on one or another measure of excellence But a state with two excellent universities has that not two flagships Flagship is a singular term a good reference for the word generally can be found here In this context flagship means as the introduction says the leading comprehensive public research university in a given U S state The only sort of exception that makes sense in this context is a system like New York s where the state university system resembles a system of franchises more than anything else With this in mind I ve edited the list to remove some schools that are plainly not a state s flagship I left a state s entry alone if I wasn t sure and so some double entries do remain someone who knows those schools better should fix those As the edit summary says I also removed a couple of external links that required paid subscriptions in order to view per WP Links to be avoided
