Blue Bombs aren't "dropped"

That looks like a dump site for a bunch of old/damaged/obsolete material

That's not very exciting.

I guess. I kind of prefer that any ordinance depot near where I live be "not very exiting". Same goes for guided missile silos and nuclear/chemical waste sites.

You really do not want the sort of excitement that comes with a dump that has active materials in it like near American U. in DC.

How about these whatzits? The blue units used for testing... what?

Those look a bit like the 20mm rounds for the original Phalanx CIWS. My college roommate was a crewman on an M-163 while in the Army. This was a 20mm Gatling-style weapon mounted in a turret on a M-113 APC, a weapon similar to Phalanx. I recall it was fired electrically, so you had to be extremely careful when handling the rounds.

Or they could be something else, lol.

For knocking down Giant Purple Snorklewackers, don't you know....

Practice rounds for a 20mm "gatling gun" like the Vulcan. Used in air craft as well as Phalanx and Armored Personal Carriers.

Thank you for the link, Chuck.
I find the letters IED interesting.
IED 67-73
HA4-10-67 M55A2

Those markings on the projectile usually indicate the "type" of projectile, explosive, armor piecing, incendiary, tracer or a combination. e.g. HEI High Explosive Incendiary

In this case as a "training round" is suspect it means inert explosive device.

I am astounded, Chuck, that your reference is found in the United States Postal Service WEB site.

What a goldmine of information! Thank you,.

On June 8, 1959, in a move that Postmaster General Arthur A.
Summerfield heralded as "of historic significance to the peoples
of the entire world," the Navy submarine USS Barbero fired a
guided missile carrying 3,000 letters towards the naval auxiliary
air station in Mayport, Florida.

LAUNCH


LANDING

It was a test version of the Regulus One equipped with landing gear for recovery purposes. These were later adapted for target drones. The successor supersonic Regulus Two never made it to operational status as the Polaris missiles were coming on line. Navy's first experience with cruise missiles.

Looks like a log burning in a fireplace.

A forest conflagration ?

Yes; looks a lot like the bed of coals from burning log(s) in my fireplace.
