Phalanx CIWS I assume? Modern day gatling gun. A Engineer buddy of mine worked on the development back in 1980 /90’s or there about. I believe at General Dynamics
Is that like a GE Mini gun?
That would be my guess. The Gatling Gun was the original multi-barrel rotating gun, but rotation was based on mechanical intervention (turning a crank). I believe the genre is now referred to as either an autocannon (if based on the 20mm M61) or minigun if based on a smaller caliber and both use an electric motor. The Phalanx is completely automated with minimal inputs from the ship, so that it can continue to protect the ship even if the ship has suffered damage. The R2D2 houses its targeting radars. The Phalanx is an autocannon with the M61 using 20mm projectiles.
FWIW, the A-10 Warthog uses a bigger version of the autocannon ... the GAU-8 Avenger 30mm.
The enemy only needs to get lucky once, Like they did at Tower 22. We must be lucky everytime. Odds will not be in our favor in the long run. Like the Russians we are discovering that drones have changed naval war. Maybe we need to go back to ironclads that can take a punch?
