US Navy amphibious ships operating MV-22B Osprey tilt-rotors will need major structural repairs after less than half their planned service lives, according to a newly released Navy document, unless a new Deck Thermal Management System (DTMS) can be developed to protect the decks from exhaust heat.
The JSF presents a slightly different problem. Its exhaust is hotter and faster, but in normal operations will not be directed at the deck for more than two minutes. Nevertheless, the Navy expects "a severe thermo-mechanical impact" on ship decks, no doubt an immense surprise: who could possibly have thought that an 18000-pound-thrust nozzle, blasting straight down at the deck at a distance measured in inches, might be a problem?
The LHA replacement modifies the LHD design to maximize support for the V-22, the CH-53, and the F-35 Joint Strike Fighter, with adequate service margins for growth. The biggest change brought about in the Global War on Terror is LHA(R). The aviation specific variant of the LHA(R) has no well deck, a monumental decision that denotes a cultural change. The Marines were seen as bringing the ACE (Aviation Coordination Element) increasingly back to sea.

Not a big deal. imo
there needs to be developed a deck coating.
maybe ceramic that will not pass the heat to the deck. or at the very least lessen the effect of the engine on the deck.
