Further to my rushed comment above, the link to Military Type Fonts is the one to follow. The pack consists of six fonts including Amarillo and what I think is actually Long Beach, but is marked as USAFF CODE. Compare this font with the demo version of Long Beach from TLai Enterprises | LongBeachUSN Info and you will see what I mean. I found the kerning in the "USAFF CODE" ttf is awful and will need some adjusting - kerning is the space between letters for those unfamiliar with printing terms. The Long Beach demo font from TLai Enterprises is missing the vowels A, E, I, O, U and the #1 but there might be enough left for codes and squadron numbers.
One of the great mysteries is how TLai Enterprises seems to "own" Long Beach. Surely a font used by the USN and decal makers for decades is in the public domain. Sure, you can't steal TLai's drawing but TLai never designed the font. The USN did that. So surely a font maker can create his own version of the USN font and identify it as such without incurring the wrath of TLai Enterprises. There are plenty of other fonts out there which duplicate commercial fonts, most famously Arial, which is efectively identical to Helvetica.
