Question

Does up-gunning an offshore patrol vessel make it a corvette?

Short answer

No; increasing gun size alone is insufficient, while fitting missiles as well can change the classification.

Notes

A larger gun alone does not make an offshore patrol vessel a corvette. Adding missiles as well changes the classification question because the weapons fit then goes beyond a gun upgrade.
