Ah. My apologies, in that case you are indeed right
.
<BLOCKQUOTE><font size="1" face="Arial">quote:</font><HR>As for the Rapier's, I don't think there's any reason to believe that they're some special new H variant... they're probably just the C model of the Rapier (plus, isn't 'H' a special designator for actual aircraft?)<HR></BLOCKQUOTE>
Well, no. It depends on the placing in the designation. If it's after the number (in this case, 44), it simply means the next "major modification" of the design. Thus, H means the next variant after G. In this sequence, only two letters are skipped - I and O, presumably because they could be confused for numbers.
Now, the reason why I suggested that he meant the F-44H goes like this. He calls the Rapier an F-54D. The trouble with this, is that F-54 is the Epee, not the Rapier. The last variant of the Epee we saw was the F-54C. Thus, if he called the Rapier F-54D, he meant that it's the next variant after the one in the game (F-44G). So, if we use the proper F-44G instead of F-54C, and move on to the next variant, it would be F-44H.
And yes, if the H was placed before or immediately after the F (eg. HF-44 or FH-44), then it would be a special designation. FH-44 would be a helicopter, whereas HF-44 would be a fighter specially modified for rescue work. Of course, that's according to the current (1962) American system.
