Ambi: "Btw, liquid fuels on board warships can be extraordinarily dangerous. The USN does not permit liquid fueled missiles aboard ship. I'd hate to see the explosion if one of those four cell Moskit launchers was hit with live warshots inside."

Monty: "Neither the Tomahawk nor the Harpoon are solid rocket fueled, so that's a bit off...
"Despite the complexities of building a Hypersonic cruise missile, certain aspects would be very useful for constructing a hypersonic aircraft too, so research there isn't necessarily a waste."
-----------------
Popeye: "The Tomahawk uses TH-dimer fuel for flight and a solid rocket booster for lift off. The fuel has a very high flash point and is considered safe for ship board use.
"The Harpoon is similar where as it uses JP-10 fuel for flight with a solid rocket booster for lift off."

One naval expert claims, "No liquid-fueled missiles on US warships 'cuz they're too dangerous," then a military fan (Am I correct?) says "Such missiles exist on US warships," and a retired navy guy says, "Yes, but these liquid-fueled missiles are safe to use on US warships."
LOL!
