Awesome to see it pass the full shock test.

3. "The underlying strength of the LCS lies in its innovative design approach, applying modularity for operational flexibility." says the USN web-page, and this is what I'll armchair-admiral now: If info came a hostile submarine was in a nearby Strait, an LCS would be sent from nearby Base with ASW Mission Packages, but what if this info turned out to be wrong, or the submarine just left, and instead a hostile Corvette was there with AShMs? Wouldn't it have been better if a Frigate had been sent??
   now the one we talked about most recently comes to my mind https://www.sinodefenceforum.com/pe...s-reports-data-etc.t5532/page-132#post-353151
   but I mean any ship which can go against several threats "at once" ... of course I know the cost of such a ship would be higher, but if LCSs will have to work in pairs and/or be covered by AB Destroyers, I don't like this "modularity"

Unusual ! to about 100 m of the Jackson and a large explosive charge for simulated an impact on the ship in War time i think.

Main points

- On Sept. 8, the Navy announced that it is effectively abandoning the LCS’ modular concept for 24 of the ships in both the Freedom and Independence-class variants. The initial four ships — which are already in service — will become testing vessels.

The Navy previously announced that a further 12 planned ships will become up-gunned and non-modular “

” All together, the Navy intends to operate 40 Littoral Combat Ships including the frigate variants, down from an initially planned 52 ships.

- If that’s confusing, each modular LCS right now has two distinct crews while at sea. The first crew is assigned to the ship specifically, while the second handles the plug-and-play module on board. When the ship returns to port and swaps modules, it swaps out the second crew, too.

Now the Navy is merging those crews together. The vessels and their crews will form into (our emphasis) “four-ship divisions of a

— either surface warfare (SUW), mine warfare (MCM) or anti-submarine warfare (ASW),” the Navy noted in a statement.
That means these new, multi-purpose vessels will become … single-purpose vessels.

The Navy will base three divisions of monohull Freedom-class warships in Florida, and another three divisions of the triple-hull trimaran Independence class in California. One LCS per division will serve as a training ship.


- Trimming the LCS will also save billions of dollars that could now pay for drones, jets and weapons. A rebooted LCS could even one day get an

, as opposed to presence which requires large numbers of ships active around the world.

These are not always mutually exclusive goals, but the Navy has decided they are when it comes to the LCS.

I'll jump in here:

1. possibly OHP hull (or enlarged, but 4500 max.)
2. possibly COGLAG propulsion (relatively quiet; but 35 knots max.)
3. AEGIS Lite, one illuminator
4. 16-cells VLS: 8 AAMs, 8 ASROCs (so that during a ASW mission the ship wouldn't rely on a helo to kill a sub, heck)
5. organic helicopter, hangar; the outer, inner spaces arranged for:
   
6. Harpoon launchers optionally from one dual to two quads,
7. torpedo tubes optionally from one single up to two triple,
8. assault boats (optionally small or big?)
   
9. enough anti-FAC protection

I know this would've required a big crew ...

... LCS/FFs as they've evolved are almost completely dependent upon Mission Modules; related to my previous criticism
https://www.sinodefenceforum.com/littoral-combat-ships-lcs.t3993/page-102#post-366763
I wonder when all Mission Modules will become available so that all those tasks can be handled by LCS/FFs? I mean fully operational fleet of all LCS/FFs (an example of the answer: 2022)?

Another apparent earthquake off Florida's Atlantic coast has been attributed to the U.S. Navy testing the seaworthiness of a new vessel.

the Navy conducted a shock trial Sept. 4 on the USS Milwaukee off the Volusia and Flagler county coastlines.

Paul Caruso at the National Earthquake Information Center says sound waves from an explosion that's part of the test registered as a 3.8 magnitude earthquake on U.S. Geological Survey seismographs as far away as Kansas.

A Navy spokeswoman says three tests are scheduled for the USS Milwaukee, each involving a 10,000-pound explosive charge.

Shock trials on another Navy vessel this summer also registered as earthquakes. Some dolphins and small whales stranded along Florida beaches in 2008 after similar tests, but officials couldn't determine what killed the animals.

my first rant against modularity:
Jul 25, 2015

and today's NavyTimes:
"The plan also kills the idea of a separate mission module crew, upending the program’s signature modularity concept where sensors and payloads could be switched out quickly to meet emerging missions."

Published on Sep 14, 2016
In June, the Navy began conducting Full Ship Shock Trials (FSST) for the Independence variant Littoral Combat Ship USS Jackson (LCS 6) off the coast of Florida. The purpose of FSST is to validate the operational survivability of new construction ships after exposure to underwater shock. Three tests were scheduled for the ship and each test was conducted with a 10,000-pound explosive charge.

On Saturday July 16, USS Jackson (LCS 6) was subjected to the third and final underwater explosion as part of her FSST. There were reports of increased seismic activity around the time of the test. The ship performed exceptionally well, sustaining minimal damage and returned to port under her own power. A large amount of data was collected during FSST on the majority of shipboard systems and the Navy will compile and analyze the data over the next several months.

Prior to any testing, the Navy ensures an exclusion zone is established around the test location. A Notice to Mariners (NOTAM) is released before each shot stating that hazardous conditions to surface vessels may be present and for vessels not involved in the test to remain clear. Similarly, the Navy takes the safety and security of marine mammals seriously, and all testing is executed to avoid the various migration patterns of marine life. Additional lookouts are posted to detect any marine mammal activity and test shots are not conducted if marine mammals are in proximity.

As part of the test program for the Littoral Combat Ship, the Navy is preparing to conduct FSST on a Freedom variant ship, USS Milwaukee (LCS 5), later this summer off the coast of Florida.

The last FSST was conducted in 2008 for USS Mesa Verde (LPD 19). It was also conducted off the coast of Florida.
