Informative reply. Although I'm surprised that there's a significant difference between the RN and Marine "standard day". Other things being equal, US and UK ships all operate at sea level, and we're pretty much in agreement about where the world's trouble spots are likely to be (and they tend to be warmer than Scunthorpe in October).
Also, I'm sure that a Typhoon in full burner is just as loud as a JSF - but the difference is that it doesn't hang around making that kind of noise.
