Deployment :

Actually to San Diego, Littoral Combat Ship Squadron 1 with the four in service Freedom, Independence, Fort Worth, Coronado now always one detached to Singapore with DESRON 7 HQ transfered there before had DDG. Remains curious a Destroyer unit for LCS ?
After this unit get four other ships includind the new LCS 6 Jackson * arrive to San Diego in 2016.

Mayport, in 2016, Littoral Combat Ship Squadron 2** six LCS on 8 yet known, normaly, Freedom class : Little Rock (LCS 9), Sioux City (LCS 11), Wichita (LCS 13), Billings (LCS 15), Indianapolis (LCS 17) and St. Louis ( LCS 19 ).

One other Littoral Combat Ship Squadron to Bahrain logically 3 others Sqns and it will stay another four LCS.

*
"We are pleased to receive the future USS Jackson into the LCS class," Buller said. "Jackson will operate out of Mayport, Florida, while conducting full ship shock trials, prior to joining her sister littoral combat ships in their homeport of San Diego in late 2016."

30mm and 57mm gun test against swarming boats. I would figure range would be on the order of a mile just based on the trajectory of the bullets. The 57mm has enough bang to make an impact but those 30mm shells really need more oomph. If they really want to keep that caliber (for weight and deck mounting limitations) they should switch to a Gatling so they can get a lot more lead out there.

Well, the maximum effective range of the Mk 46 30mm naval gun is about 4,400 yards. That's about 2 1/2 miles. They are using an infrared targeting system with a laser range finder to control the gun. it can either be set to automatic for those types of targets, or fired manually by the operator.

The fire rate is 200 rounds per minute, or a little over three rounds per second. I am sure they shoot in singles or five round bursts in these test engagements. But once they are on target in a real combat situation, they would sustain their rate of fire for 3-4 seconds at a time and tear up those small boats. Each gun carriers four hundred rounds.

IMHO, for the types of boats shown, or even larger speed boats, the 30mm gun is going to be, in addition to the 57mm gun, plenty adequate for those types of targets.

I recalled we had been talking about Mk 46/110 in
US Navy DDG 1000 Zumwalt Class
now I located those posts: around

I also recall reading somewhere the fancy 57 mm "3P rounds"

are pretty expensive, like $5k ... but they can be be shot for example in the time-mode, to burst above an incoming boat (and "hurt" the crew there)

Not just guns... Coronado fired SeaRAM (1st time at sea) too
Littoral Combat Ship USS Coronado (LCS 4) Conducts Live Fire Test of Guns and SeaRAM
Littoral Combat Ship USS Coronado (LCS 4) successfully tracked and neutralized both single and multiple fast inshore attack craft during live-fire testing off the coast of California July 18-22. It also demonstrated the ability to counter incoming anti-ship missiles when it successfully executed the first even at-sea demonstration of the SeaRAM Point-Defense Weapon System on August 14.

Malay-Carat-2015.jpg

Naval Today said:
The 21st annual Cooperation Afloat Readiness and Training (CARAT) exercise between the U.S. Navy, U.S. Marine Corps, and the Malaysian Armed Forces began Aug. 17 with opening ceremonies in Sandakan, Malaysia.

CARAT Malaysia 2015 consists of five days of shore-based and at-sea training events, designed to address shared maritime security concerns, build relationships, and enhance interoperability among participating forces.

CARAT is a series of bilateral naval exercises between the U.S. Navy, U.S. Marine Corps, and the armed forces of Bangladesh, Brunei, Cambodia, Indonesia, Malaysia, the Philippines, Singapore, Thailand and Timor-Leste.

The US continues to march through South East Asia with its long standing Cooperation Afloat Readiness and Training (CARAT) exercises. This month it is Malaysia's turn.

This article sounds a little sensational. It is from the National Interest, but I'll post it anyhow.

The U.S. Navy appears to have a new low-cost plan to counter Iran’s fleet of speedboats.

the first test of the Longbow Hellfire missile system from a Littoral Combat Ship. The tests, which were announced at the end of last month, took place in mid-June, according to a Navy press release.

“During the mid-June tests off the coast of Virginia, the modified Longbow Hellfire missiles successfully destroyed a series of maneuvering small boat targets. The system "hit" seven of eight targets engaged, with the lone miss attributed to a target issue not related to the missile's capability,” the press release said.

Each LCS will be able to hold 24 Longbow Hellfire missiles, according to Motley Fool. One advantage the Longbow Hellfire missiles hold over other missiles considered, most notably the Raytheon’s Griffin IIB missile, was that its “fire and forget” feature allowed numerous missiles to be fired simultaneously.

The SSMM will be fully integrated and deployed on the LCS starting in 2017.
Good article that further details the news and pics of the exercise held a few weeks ago reported here on this thread and in the US Military News thread. Here's a pic from the actual exercise where three fast boats were destroyed together.

They have since held exercises with the same SSMM package using the 30mm guns, the 57MM guns, and I believe even the SeaRAM missiles to destroy swarming fast boats.

now that's interesting
Navy To Award Lockheed Martin Sole-Source Contract For Frigate Combat Management System
Naval Sea Systems Command (NAVSEA) intends to award a sole-source contract to Lockheed Martin for a combat management system for the future frigates, after the Navy determined the company is the only one capable of delivering the system without slowing down the rest of the acquisition program.

The current Littoral Combat Ship fleet is split evenly between Lockheed Martin’s Freedom-variant hull design with the Combat Management System Component Based Total Ship System – 21st Century (COMBATSS-21) system and Austal’s Independence-variant with a Northrop Grumman Integrated Combat Management System. When the LCS program shifts to the frigate program, though, the Navy has said it wants to take the opportunity to whittle down to a single, common combat management system (CMS).

Lockheed Martin Mission Systems and Training (LM MST) will provide that common system, according to a notification on FedBizOpps (FBO).

“Following announcement of the future modified LCS, the FF, the Navy conducted a review of potential common combat management systems to procure for the FF,” NAVSEA spokesman Chris Johnson told USNI News.
“The Navy determined that COMBATTS-21 was the only common combat management system which would not result in unacceptable delays to FF design and acquisition timelines.”

According to FBO, the contract would cover work from Fiscal Years 2016 to 2021, including “the development, software and hardware integration, procurement, and delivery of two COMBATSS-21 CMS for LCS Class Frigate ships.”

The contract would also buy the hardware and develop the software so that the common CMS could be backfitted onto the Freedom- and Independence-variant LCSs, according to the notice.

The contract will also include options for logistics products to support the CMS, hardware for two more FF ship sets and engineering support.

“LM MST is the only source that can meet the Navy’s Frigate shipbuilding program schedules. This notice is not a request for competitive proposals,” the FBO notice reiterates.

The Navy could not yet comment on why Lockheed Martin was deemed the sole capable source for the common CMS contract.

In April, Program Executive Officer for LCS

the Navy may keep the two hull designs in the frigate program but the FFs would have common combat systems, common over-the-horizon radars and over-the-horizon missiles, and possibly common consoles. He said at the time that he had about 18 months to pick which specific systems he would include in the final frigate design.
