"hundreds of bullets per minute" - laughs in thousands of times per minute

Might be the lowest cost per shot defence system in the ship

[larrymead]

I've always wondered if you could mount one of these to rotate down from a B-52 bay for SAM defense. One bay for the gun system the other for ammo.

Not even Megatron can survive this American Gun Devil

There’s a story about one I think in the gulf war. The American ship had an incoming missile and deployed chaff launchers around the ship. It confused the radar and this weapon strafed the bridge. Nobody was hurt but it made a part of the bridge look like swiss cheese.

When you hear the it's about to get real

Their should be a comparison between the US SCWIS vs SOVIET defense system; the number of ammunition it can carry, load time, and shots at a target.

[DrCarlBooze]

You call 20mm small? It’s pretty big for a bullet especially when they are ripping your boat or jet in half.

[RalphGoodson]

Yep, fires a lot of bullets. Does it hit anything?

[cristolll]

The 1130 on type 055 is a 30mm 10 barrels cwis at 10kbullets/sec. The newer version 2030 is 20 barrels version which is 20k bullets/sec

These are the things they allow us to know imagine what’s on the other side of the room

We shot down a towed target in only 50 rounds once with the CIWS mount inworked on.

Because of it's relatively short effective range (1-1.5 km), it is being replaced by the SeaRAM missile system.

[rspcoach]

It's not how powerful but rather effective and accurate.

[davidrosenlund]

The Navy doesn't make modifications to weapon systems. They make recommendations to the manufacturer.

[nekozabuza]

you mean THOUSANDS of bullets a minute

[justinperry]

Not sure why these ain't sent to places like Ukraine amd used from the ground rooftops etc I'm sure we have used them around some of our bases

[blayneharvey]

Bro said the last line of defense
:laughs in killing everything that moves

[wrathfulcoma]

Small ? Excuse me, if those bullets are small you’ve been reading the measuring stick wrong
