The Swedish Visby class corvette showed up at the DSEi defense systems and equipment international London. It looks cool:
That being said, I’m rather dubious of the merits of full on stealth for surface combatants.
Given the harsh environment (spray, etc.) and the fact that some inexpensive radars can find the wake of ships, I’m not sure that it means a whole lot.
Of course, the real stealth ships, submarines, have been around for nearly 100 years now.
