I have seen the 4921 and like it. Here’s a thread on a Sino defense forum I posted regarding it.
US Navy Patrol frigate proposal shown at DIMDEX

Good discussion there.
This USNI Proceedings proposal is also a good one and we do need them.
We have to get a CINC and congress in there who will build them.
He was far from my 1st choice, but I have to say that Romney has some good ideas and things to say about the military and US Navy needs.
To his credit Romney is the only one talking about our MOST IMPORTANT national security need.
Rebuilding the USN through the expansion of the number of ships at sea.
Without USN domination of the seas, we would certainly not maintain our place in the world and would not be a "super power". Everything we purchase from overseas, from wine, to BMWs to oil would be expensive and scarce. No commerical flag vessel would be safe anywhere. The worldwide economy would be in complete shambgles and chaos, at best. Starvation and disease would dominate the human condition when it was not dominated by war.
I know some folks think I'm exaggerating, but I'm not.
It is essential civilized man maintain absolute domination of the seas. In history when that condition did not exist, the world was a far, far different place.
And it can be again.
To Romney's credit, he sees that.
