How's about the Phalanx
.
A "last line of defense" for ships, the Phalanx is a rapid-fire,
computer-controlled radar and 20-millimeter gun system that can
automatically track and destroy close-range enemy threats such as
low-flying cruise missiles, small boats and helicopters. Since 1979,
more than 850 Phalanx systems have been built and deployed in the
navies of 22 allied nations, Raytheon says.

Firing 3,000 to 4,500 armor-piercing rounds per minute, the Phalanx was
battle-tested by the British during the Falklands War. The advanced
Phalanx 1B version includes advanced Forward Looking Infrared (FLIR)
and beefier gun barrels.

First you have to turn the Phalanx on. It has a warm up time.
