Patches from the Pentagons Black World

"I'd say don't tell anyone what you just saw, but no one would believe you anyway."

I have always been a huge fan of both conspiracies and classified operations/missions from yester-year. 
A few weeks ago I stumbled upon a book that documented real patches given to US military personnel involved in secret operations and classified test flight programs (such as the SR-71 Blackbird, for example).
Some were very cool, others were still totally shrouded in mystery on what they represented and did on those missions. We still don't know to this day what some of them mean.
I was obsessed, and found it to be such an interesting part of history. I spoke to the Waldo Dynamics designer, Henry, and asked him to redesign some of our favorites!

What you're looking at are authentic recreations of the original designs using modern patch making technology. The only real difference is that they are generally speaking more detailed. 
They are all roughly between 7-6cm in diameter with Velcro sewn onto the back for easy application. 

Below I will write a short description of the origin of each patch so you can see which history/story might align with you. All exerts are taken directly from the book "I COULD TELL YOU YOU BUT THEN YOU WOULD HAVE TO BE DESTROYED BY ME - Emblems from the Pentagon's Black World" by Trevor Paglen;

The Green Door;

The origins and purpose of this patch remain obscure. The green figure holding
the sword (or dagger) wears the cloak-and dagger garb often associated with
black projects. There is a star in the northern hemisphere under the letter "S"
and another red star in the American Southwest. The red star might refer to an
operating location, but the patch provides no real clue as to where it might be.
The Southwest is home to numerous classified units. Air Force Space Command
in Colorado; Kirtland Air Force Base in New Mexico; White Sands, New
Mexico; Groom Lake, Nevada; and the Tonopah Test Range are all possibilities,
and there are many more.
The words "A Lifetime of Silence" no doubt refer to the fact that members of
this unit or project cannot speak about what they do. The image of a "Green
Door" is also obscure. Military intelligence officers have a tradition of working
behind locked green vault doors, but the symbol is widely used in popular
culture to designate an inaccessible place.

G.H.O.S.T.;

One of the more recent patches from the "Ghost Squadron" based at Groom
Lake. The design of the skull's helmet indicates that "Ghost" is a helicopter
unit. The footprints on the helmet mark the trace of the "Jolly Green Giant," a
symbol that represents helicopter search and rescue missions. This patch also
seems to indicate that "G.H.O.S.T." is an acronym for the unit. The meaning of
the acronym is unclear.

Prowler;

This is one of two patches known to be associated with a black Lockheed
Martin Skunk Works project named "Prowler" or "Desert Prowler." The
project was active as of late 2005.

Project Zipper;

This patch represents an unknown project undertaken by the 413th Flight Test
Squadron. The zipper seems to refer to the fact that the project cannot be
discussed. The first part of the phrase "We make threats" might refer to
making simulated (or real) electronic "threats" against aircraft.

Never Before. Never Again;

A National Reconnaissance Office program patch, whose referent remains
entirely obscure. The Latin inscription translates as "Never Before, Never
Again.".

I Could Tell You But...;

The phrase "I could tell you but then you would have to be destroyed by me" is a fun jab at a mistranslation of a grammatically incorrect Latin motto on early versions of the VFA-41 unit patch (the United States Navy's Strike Fighter Squadron 41, globally known as the "Black Aces"). While that squadron publicly flew F/A-18F Super Hornets, select detachments within the unit historically worked alongside the Air Force, Lockheed Martin's Skunk Works, and teams at Area 51 to test and integrate stealth technology into naval aviation. 
The three black bars in the center of the patch represent stealth aircraft signatures or classified geometric shapes being evaluated for radar.
