Can anyone explain on the freedom class the two open areas just forward of the 30mm gun positions and what they may be used for I have also heard of aft ssm area {small} just aft of the 30mm guns in between the ram launcher could this be used for the hellfires?

I believe those areas forward of the 30mm guns were originally for NLOS missile VLS? I could be wrong. At the moment I think those areas are for decoy launchers.

The VLS space behind the 57mm gun on the independence class was also for the NLOS, I think.

I realize this may seem strange but wouldn't a small ssm like the original Israeli Gabriel missile be the ideal ssm for this ship I believe its range was about 12 miles or so it would have to be brought up modern standards but that should not be to hard in fact the latest versions are approaching harpoon type ranges of 60+ miles. This along with essm for air defense should be very adequate for weapons load out. And thank for the info these weapon may fit into the areas I was asking about with minor modifications. Would appreciate your thoughts about theses possibilities.

in my recent post on Naval Guns http://www.sinodefenceforum.com/wor...dg-1000-zumwalt-class-15-5546.html#post309407
I quoted somebody's question:

So if the 57mm gun doesn’t cut it, why keep it on the LCS?

now found something which sorta addresses it:

Anyway, it turns out that the Mk110 has significant reliability and performance problems on the LCS as documented by various reports. As if that’s not bad enough, it turns out that the Mk110 is rendered ineffective due to vibration when the LCS is at any speed. To be fair, that’s probably more of an LCS structural design issue than a gun failing.

Do you think it's true, I mean if the 57mm Mk 110 really has issues? I used google, found stuff in the discussion below

If the issues are with the 57mm cant be resolved then what kind of system would be of use. What about the Italian fast 40 system or as I have suggested a 5" 54 or 62 system or maybe the 76 super rapido system as these all have been proven and are in use. Maybe we should just ditch this idea altogether and over from scratch.

first of all, dtulsa, I didn't know there's no fire control radar on LCS for Mk110 57mm (as

(see? both radar and EO, works for "all" calibers -- use google with
Selex NA-25X
if you want to know more)

EDIT
according this officially-looking document:

the 57mm fire-control differs between the LCS-1 and -2 ...

DORNA (Spanish) Electro-Optical/Infrared (EO/IR)
for 57 mm gun fire control

and

Sea Star SAFIRE EO/IR for 57 mm gun fire control

Is it really like this??

Again lack of planning/foresight in making this vessel and I bet installing these guidance systems is going drive up the cost so what are we supposed to do as it now looks like it cant shoot either boy oh boy what a mess.

the type of radar (Freedom-class):

Among the ships equipped with TRS-3D are the National Security Cutters of the U.S. Coast Guard, and outside the U.S., the K130 corvettes of the German Navy, the "Squadron 2000" patrol boats of the Finnish Navy and the Norwegian Coast Guard "Nordkapp" and "Svalbard" icebreakers.

Airbus Defense and Space, Inc. has installed and put into operation the third TRS-3D naval radar for the U.S. Navy's Littoral Combat Ship (LCS) program through its agreement with LCS prime contractor, Lockheed Martin. The radar has been integrated on the third Freedom variant of the new Littoral Combat Ships, Milwaukee (LCS 5). In total, eight TRS-3D radars, designated AN/SPS-75 by the U.S. Navy, have passed their equipment acceptance tests, each now in varying stages of installation within the USS Freedom variant ships. Performance testing with the LCS Combat System continues and plans to upgrade the ships radar to the TRS-4D are in development.

"The TRS-3D is the choice for ships with multi-mode radar requirements, as evidenced by it being a global market leader in its class," explains Aaron Johnson, Director of Sales and Marketing at Airbus Defense and Space Inc.'s Communications, Intelligence, Security & Electronics division. "We're proud to support Lockheed Martin and the LCS program with our products."

The TRS-3D is a three-dimensional, multimode naval radar for surveillance, self-defense, gunfire support, and helicopter control. It is used to automatically locate and track all types of air and sea targets.

Among the ships equipped with TRS-3D are the National Security Cutters of the U.S. Coast Guard, and outside the U.S., the K130 corvettes of the German Navy, the "Squadron 2000" patrol boats of the Finnish Navy and the Norwegian Coast Guard "Nordkapp" and "Svalbard" icebreakers.

Littoral combat ships are fast, agile surface combatants optimized for operating in the highly trafficked near-shore regions of the world against asymmetric "anti-access" threats. Through its innovative design, LCS can be reconfigured for surface warfare, anti-submarine warfare, and mine countermeasures.

The two radars used for the two classes of LCS have significant target tracking and acquisition capabilities. I bet they could be integrated, as is, with the MK-41 VLS along witrh the necessary illuminators for some of the a2a missiles.

AN/SPS-75 TRS 3D multi-mode radar for Freedom Class LCS
Range: 110 miles
Altitude: Up to 60,000 ft.
Optimizations:
- Muliple Targets, Multiple direction
- Small, fast moving targets in severe clutter (littorals)
Role:
- Air Surveillance
- Target Tracking
- Target acquisition for defensive weapons

Note: The Sea Giraff AN.SPS-77 is housed in an enclosed. stealth enc;losure on top of the deck house.

AN/SPS 77 Sea Giraff Multi-mode radar for Independence Class LCS
Range: 120 miles
Altitude: Up to 65,000 ft.
Optimizations:
- Muliple Targets, Multiple direction
- Small, fast moving targets in severe clutter (littorals)
Role:
- Air and surface Surveillance
- Target Tracking
- Target acquisition for defensive weapons
