Far be it from me to argue with an enthusiast, but while I have heard of the Invincible-Class Cruisers I have never heard the name Fearnaught. Dreadnought, on the other hand, is of course a familiar term in a naval context.You're too much of an academic to pretend like you don't know the history of these names and fabrics.
Jokes aside, between this and the Invincible, I think it's kind of cool that Dugdale is giving a little nod to the martial origins of CM materials and styles. I hope they have a POW in there named after the HMS Prince of Wales for example. Or some sort of tartan/check for the HMS Duke of Edinburgh. How about the HMS Indefatigable, a high twist, no wrinkle travel worsted? HMS Dauntless, an 18oz tweed that will repel wind, rain, sleet, snow, and, if made into a 3-piece suit on an SF CM purist, potential romantic partners and employers.
I can do this all day but you get the idea. If the sun never set on the British Empire, it's probably 60% because Royal Navy vessels have the best names.
