Great pic at 39. Love to see how the transom converts to a ramp and integrates to the overhead interior crane system. It says it can do underway launch and recovery, so the ramp must lower into the water.
Both classes are under armed, crews are too small, and of doubtful use in a fight. To survive, they must never leave the battle group protective ‘bubble’. The long service FFG-7 class frigates are going away without replacement and the LCS is a ‘swoose’ design — half swan and half goose that cannot do either job well.
“I believe 5 sailors can operate the entire ship.”
Maybe the Navy will outsource those 5 jobs to a low-cost country like...China...to help reduce costs. Hell, that’s what all “American companies” are doing these days.
Wrong ship. That’s the competitor. It’s a Freedom class, not an Independence class.
And yes, the navy built two incompatible designs for the same mission. Double your costs - it’s just taxpayer money to buy votes for incumbent politicians.
Your comments are right on target IMHO.
It looks to me that the center of the stern has large hinges both port and starboard of the centerline. I would guess saloon style doors with a ramp ready to come out.
Your thoughts? Did you see that?
Some more articles, with pics, relating to the USS Freedom transom:

Googling for “USS Freedom” stern ramp gets some nice images

Yeah, I agree, if I trust my eyes to extrapolate those marks. It’s logical, what else would they do? Ramp comes out with rollers built for a particular large RIB like an 11m, draws it into the hull and integrages with the the overhead rail crane to store it in a handy spot.
Great links, thanks, esp the bottom one. Terrific article.
The monohull’s stern ramp system seems ideal, but those two “water-wing” boxes welded on either side of the transom might prove to be a liability to boat launch and recovery, or not. The water-wings seem a crude afterthought, probably after the boat weighed in over estimates. If this becomes a class, I’ll bet they revise the hull and eliminate the water-wings.
I'd expect them to stay. Would require a major redesign to get that bouyancy into the ship. They don't appear to interfere with launch and recovery

The top article in #48 has
Cmdr. Randy Garner, the ships Gold Crew skipper and the man in charge for Freedoms trial deployment to 4th Fleet, said the tanks ride above the waterline and would only come into play to give the ship additional buoyancy, if, for some reason, we were lower in the water. Which is to say, if the Freedom took damage in combat and started to sink, Navy engineers think its water wings would help the ship stay afloat, or at least delay its sinking until everyone could get off.If you had combat damage that compromised the water-tightness of the transom, and the ship started to sink, having the mission bay fill with water would be very unhappy-making.
It better be a good door, and not a design copied from North Sea car ferries of a few years ago.
I have some old knowledge of recovering RIBs and other inflatables up ramps. It really is about ideal. The trimaran requires positioning under a crane system, then being yanked up by some wires. While this is far better than a single-point crane or even side davits, it still leaves a lot to be desired.
But I’d love to T&E it. Oh, yes I would. I envy the SEALs adn SWCCs who are assigned to play cowboy on that T&E, working all of the bugs out! I imagine dropping from the wires while underway is a blast.
But all four lift points better release at exactly the same time. Imagne if an aft wire “hangs up” for a few seconds after the other three lift points have let go. Underway.
That would get sporty. Still love to try it.
Youtube has some nice videos on USS Freedom and USS Independence

BTW, that video includes footage of boat launch and recovery through the transom
Nice video, made before the waterwings were added. I really like the big RIB up the transom method, but I’d also like to see the trimaran’s cable system. The transom doors on the monohull would be a weak point if it takes battle damage and can’t function, or worse, can’t close. To some extent, the waterwings might protect the vulnerable doors from fire. They also might subdue cross seas for launch in rough weather. (Or they might amplify them in certain circumstances.)
