Not entirely correct I'm afraid, military airfields in the US often times start with N(but not always!), and W seems to be somewhat common as well:
A couple of N's:
NZY - NAS North Island in California
NTU - NAS Oceana in Virginia
NXX - NAS/JRB Willow Grove in Pennsylvania
(there are many more)
Some W's:
WRI - McGwire AFB in New Jersey
WDG - Enid Regional Airport in Oklahoma
WYS - Yellowstone Airport in Montana
