Not really sure where I picked up the term "clear anodized"...probably in a metal shop class somewhere. It's a term for an anodized finish that lets most if not all of the base color of the metal show through, vice a colored surface. Aluminum can be electronically anodized, but still be silver, for example. (Come to think of it now, I haven't used that term myself in years.)
I've been at it for about 18 years as a civie with the USN and USMC, and have yet to encounter a white GCU...except on some developmental types which aren't or weren't fielded. DAMASK is one I can think of...can't think of any other white munitions - other than Mk20/CBU-99/100's, Walleye, Shrike, Harpoon, HARM, or other early A/A missiles; but those aren't laser guided. Certainly all of the USN laser guided A/G munitions I've delt with have had OD-ish or metallic GCU's (aladine, possibly). And most of the newer ones (like GBU-24) have been Joint developments. Only the bomb bodies vary, from what I've seen. If ou've been working at Eglin, yeah - I could see how you'd come across a big lot of shared assets.
Next time you're at Edwards, look me up...
