Fireballs like this results from combustion, not HE detonation. Whatever made that fireball it is not the filling in a 5.7cm shell.

Here's a picture of a Canadian 5.7cm gun and 3P ammo in use at the SinkEx of USS Hayler from Navsource. I have to say the explosion is out of all proportion to the scale of the ammo involved.

If you want to see an ugly war canoe, look at the RN's 'Daring' class - roughly 6500 tons designed by comittee and built to the cheapest common denominator. There is more space devoted to 2 man cabins for junior rates than to weapons/sensors.
They have been so long in the design stage, they were referred to as the 'lost horizon' class in the 'fleet' (what we have left of one anyway). It seems British warships these days are being designed to be quiet, stealthy and habitable at the expense of a decent weapons fit. How anyone can say a 6500 ton metal block painted grey with numbers on the side is stealthy beats me......

Actually, Chuck, it is "considered" the "close-in weapon". The 3-P ammo is derivative of the Reagan "Star Wars" program and is an intelligent fragmentation device that puts a cloud of explosively formed projectiles in the path of the incoming missile when it senses an appropriate range and favorable angle.

The small size of ready use ammo drum would suggest the system would be ineffective against saturation attack. In any case, >200 rounds a minute would seem rather deficient for this use, and several existing weapons, Italian 40mm twin Branda guns for example, would seem to be poised to shoot mauch faster and do the CIWS job better than a single 57mm gun.

Don't think they're wasting the 155mm guns on small boats less than a kilometer away.
No. Not if the 155mm gun can hit the boat.

My opinionated opinion. :lol_spit_1:
I always admired how the Coast Guard Cutters looked in their white paint. But running rust would turn them pink after a month out in the Bering Sea! :lol_1: Trust me, my DE was just across the pier from those pink cutters and we had a laugh!
At least our deck gang didn't have to deal with that! The grey didn't look quite so bad with a few rust streaks.

It will be interesting to put this ship pierside without tugs as was often done with Perrys and virtually everything smaller than a carrier before 1990.

Unless bridge wings pop out, there is no camera system likely to avoid giving the OOD an extreme need to change underwear.

Even underway refueling ought to have a higher than normal "pucker factor".

The 57mm on the DDG-1k should be the pods on either sides of the hangar roof:

United Defense (Bofors) Mk.110 57mm/70 gun with Mk.295 "3P" ammunition. It is the functional equivalent of the Swedish Navy 57mm Mk.3.

This gun is also to be fit to DDG-1000 (where, I do not know, but likely in a stealth-spoiling position high on the superstructure).

The cyclic rate of fire is 220 rounds/minute, and the ready service drum (120 rounds) takes two minutes to change.

The Mk.295 shell weighs 5.3 pounds.

Whose gun is it? Bofor? 57mm has not been a common US caliber. What's wrong with the Italian 75mm gun previously used by lighter US combatants?

Bertholf

What is that gun on the fore deck?

by Werner » Thu Dec 27, 2007 2:32 pm

Speed is about 30 knots (29 sustained), range 12,000 miles (as opposed to LCS' 4,000 @ 20 and 900 @ 50), endurance is 180 days on station (LCS' endurance is "336 hours" or 14 days).

CODAG plant and the same military fit as LCS-1.

It looks like the cutter design (in series production) will wind up costing about $380,000,000.

Hey, that is actually a pretty slick looking cutter. Any word on what her speed and endurance are?

by Werner » Thu Dec 27, 2007 12:05 pm

In the current USNI Proceedings, there is a discussion suggesting the USN shift to the new USCG Bertholf design, which has roughly the same military characteristics (except the speed), and a mission time measured in months instead of hours.
