ISRAELI NAVY INAUGURATES FIRST SAAR 6 CORVETTE

50 kts seems way incorrect

“light: Norwegian corvettes have up to 60

The missile cruiser USS Long Beach was kept around home because she couldn’t keep up with the other ships.

You might be thinking of another ship? USS Long Beach had the same max speed as most other USA surface combatants, 30+ kts. She completed 15 WestPac deployments and deployed multiple times during Viet Nam and Gulf War 1.

Carriers turn into the wind to launch aircraft, but if there is little head wind they require the speed to help the aircraft get lift and fly away.

Long Beach was nuclear powered, wasn’t it ?

[Former Proud Canadian]

Penance for the holocaust.

[sparklite2]

Yes. the first nuclear powered surface warship in the world

The source I had for this has been 'updated' so most of the following is gone. Maybe it turned out to be a crock, I don't know. Seems legit, but maybe it isn't. I'll let you decide.

USS Long Beach  CGN-9

If you wanted to serve on a ship that rarely left port in the US, the Long Beach was where to be. We couldn’t do much more than 30 knots with a clean hull, so we couldn’t keep up with the carriers, so we rarely left port. The reason was that the Long Beach was originally going to be a DLG weighing 12,000 tons. By the time the USN was done expanding it, it weighed 14,000 tons. During sea trials, it was feared that the ship would roll over because it was so top heavy, so 2000 tons of lead was added along the keel to raise the weight to 16,000 tons.

In the mid 1960’s, the 2000 tons of lead in the keel shifted so the ship didn’t roll symmetrically, and jerked 2 or three times each way rather than rolling smoothly and then snapped upright. Additionally, one of the shafts was out of balance so it vibrated a lot when it was over 20 knots. The top heaviness also caused it to roll up to 35 degrees to each side which made the steam generator sloshing from side to side real interesting and left foot prints 6 feet up the walls at the ends of the athwart ship passage ways where a sailor was forced to stop himself during a roll. In heavy seas, the nose would dive, and water would come up thru the bull nose and cover the forward Tarrier launchers. What a ride!

I had heard 50, but it may be incorrect. Sea trials got to over 40 so maybe someone rounded up.

The direct attacks on Iran will be by the IAF and the Saudi air force with the UAE flying cover.

The US Navy will protect the gulf from over flying Iranian missiles and aircraft

[Vinnie]

Let us not forget Iran has several DE submarines. And I’ll bet they are lurking around US capital ships and the Straits.

[bert]

You are correct.

I’ll bet the precise location of each of those submarines is known and tracked

[dp0622]

I like that.

[Vinnie]

I’ll bet the precise location of each of those submarines is known and tracked

I hope you are correct. Have my doubts though. DE subs can be extremely difficult to find and there have been allied DE subs penetrating our carrier nets during war games.
Surfacing very close to the carrier.

[ETCM]

Most of that is just embellished, but the “not leaving port because we couldn’t keep up with the carriers” is just false and shows the author doesn’t know much about the USN. All of our major surface combatants, including Arleigh Burke destroyers and Ticonderoga cruisers, top out at 30-35 kts. It’s also pretty rare for carriers to go faster than that outside of sea trials. Additionally, the ship’s deployment history is well documented.

[Tallguy]

Carrying an F-35 is one thing. Having the thing melt your flight deck is a major bummer though.

[Tallguy]

Diesel? Corvette’s typically are coastal ships that don’t require fleet speeds. Nice hull though. Put a gas tubine in that puppy and it would probably go 30 knots. It’s probably an option.

[Tallguy]

AIP subs (Air Independent Propulsion) are the poor-man’s nuke boat. I think that’s what you are referring to.

DE’s are older still (technologically) and rely on snorkeling so charge batteries and ventilate just as the late-War U-boats did. When a DE “snorts” every sub in the area hears it, and they have to do it regularly.

Neither sub has the U/W speed or endurance to keep up with a carrier group though ambushes are possible in constricted waters.

[Vinnie]

Yes AIP. They concern me.
