@WTFPurpleAlpaca @Terry Close encounters aren't common occurrences with these types of vessels.
You engage from many miles away, your targets often beyond the horizon.
As for countering small air units, many ships are already equipped for that (pic related).
While many corvette class ships opt for a small cannon on the front (previous post shows those), others are fitted with an AA 20mm Vulcan cannon.
These things are more than a match for swarms of drones.
Accurate, fast, and fully automated.
A cloud of led at a press of a button.
Vulcan cannons are wild.
@Terry It is indeed stealthy.
Not to be "that guy", but the stealth refers to its radar signature.
Although, it's kinda moot, since all modern ships of various classes look pretty much the same.
Here are a selection of corvette class ships of different countries.
I draw, code, and make memes sometimes.
