Comment [edited]: "We trained literally daily back in the united states. Some of it was in the field, but most of it was in an office doing math and etc.. Some of the training was a bit tedious for sure, but it wasn't a bad job at all. We used laptops to calculate firing data of course, but we had to know how to do everything manually. When calculating firing data you gotta take into account so many factors. More than just the target coordinates. There's gun coordinates, gun altitude, target coordinates, target altitude, MVV (muzzle velocity variation) which is the wear and tear of the tube over time (these numbers come from routine tests done on the cannon). We also took into account meteorological data (temperature, wind speed, etc) for every thousand feet. We'd get that info every hour from a weather team at another location. We had to take into account the temperature of the propellant, which we got from the gunline every so often. We would literally take into account the rotation of the earth. We'd also take into account things like time detonation for the rounds. We would tell the gunline what time to set their rounds to, to ensure it explodes just above the ground. We had to calculate the time from shooting until impact. We would tell the forward observers (infantry) 10 seconds before rounds hit the target. If infantry wanted to do a correction ("up 50 meters, down 100"), we would calculate all of the new data and tell the gunline the new deflection (left/right) and quadrant (up/down). Every round shot is manually recorded onto a record of fire sheet. For illumination rounds, we would have to calculate the exact coordinates of where the cannister would land after the illum round ignites in the sky, to ensure the cannister doesn't land on anything important.. This is necessary to ensure the cannisters of the illum rounds don't fall on people / homes / etc.."

Bikini Atom Bomb


.


On September 25, 1946, 75 ships were quarantined for radioactive contamination tests after the second nuclear bomb was dropped at Bikini Atoll. 

Operation Crossroads is completed with the dropping of an atomic bomb on Bikini Atoll. Tests of many kinds were put in place on ships surrounding the Atoll and special goggles issued to protect the eyes of those watching. A Superfortress took off from Kwajalein and dropped just one missile.

KS LS Bikini Atoll. 5 /73 target ships sunk. Superstructure wrecked on Aircraft carrier USS "Independent" . USS "Pensacola", badly damaged.

Bio-Risks - Chinese Competition 

The Dugway Proving Ground is a US government facility that tests some of the deadliest chemical and biological agents on earth. Despite the dangerous experimentation, the facility has had some major slip ups.

Engineered Viruses Are the New Biological Weapons > .

In the world of synthetic biology, a microbe is seen as a structural frame on which to add genes & DNA. The microbe will be tested and have its performance improved, so it can hopefully do something useful for the world.

But this potential to modify living organisms and steer them toward global problems is often met with a dark side.

The National Academies of Science released a major report titled Biodefense in the Age of Synthetic Biology with a ranked list of threat concerns. High on the list is recreating known pathogenic viruses and making existing bacteria more dangerous, lowest is modifying the human genome with gene drives

Often when people think about bioweapons, some kind of organism being weaponized comes to mind, like anthrax bacteria or the smallpox virus.

The NAS synthetic biology report includes some suggestions that involve developing detection tools and computational approaches that can better screen for any rogue engineered organisms. And this is exactly what Ginkgo Bioworks, a synthetic organism factory, is working on.

Synthetic biology—including DNA synthesis and gene editing—has increased severity of threats from potential bioterrorists.
