No, not at this time in 1:350 scale. I have not heard of any of the plastic or resin companies working on one.
Iron Shipwright makes a GUAM in resin and brass in 1:350 scale
Academy is working on a WASP-class LHD. I saw the test shots at the IPMS Nats and was impressed with the work. Expect it to be available in about 6 months ( and expect the cost to be in the 200 dollar range). One-piece full hull with welldeck and hangar deck. The test shot didn't have the flight deck cemented so that the various decks could be displayed. It will come with a full ait wing and a couple of LCACs.
It may have plastic railings a'la the Perry which will need to be replaced with some PE. It looks good and will be a good addition to begin filling the Gator-freighter niche.
