I feel like this could be equal parts good and bad

Engineers at Picatinny Arsenal are in the midst of crafting a generation of transparent explosives that can be used on everything from invisible mines to self-destructing optics.

Deep inside the U.S. Army Armament Research, Development and Engineering Center, or ARDEC, at Picatinny Arsenal are engineers Victor Stepanov and Rajen Patel who are busy burning lean muscle tissue into the night to craft what they term “amorphous explosives.”

Accomplished with nanotechnology, the concept is to modify already proven battlefield shaping explosive compounds to create new ones that are clear as glass.

“If you ever seen a glassblower work, they heat the material above its glass transition point (Tg) until the glass softens. Then, the glassblower manipulates the glass, easily molding it before it cools,” said Patel. “Well, with this project, we can basically do the same thing with amorphous energetics: heat them above Tg and manipulate the structure to form complex shapes.”

What would the shapes be used for? Lots of stuff for the next gen warfighter like clear reactive armor for use in detonating anti-tank weapons, optics that can be blown up if they fall into enemy hands– such as on a drone that is lost or shot down– and even invisible mines.

In short, if you want it clear, and to go boom, this tech is key.

Patel says that key to the development is being able to keep it in its amorphous state long-term.

“This is especially true when we talk about its military application, where we could keep something in a bunker for twenty years in a hot desert,” he said.

New grenade is southpaw approved

The fine folks at Picatinny Arsenal are coming up with a hand grenade for the 21st Century that is a lot safer to handle and gives some high tech options to the grunt end user.

The current arsenal standard, the M67 grenade, dates back to Vietnam and uses a pyrotechnic delay fuze to set off about 6.5 ounces of Comp B. The thing is, it’s right hand friendly –the pin that holds the spoon down is oriented to be pulled with the left hand, meaning southpaws are trained to hold the grenade upside down, such as thus:

The new baseball that the Army could be pitching, some five years in the making, will use a fully electronic fuze that is accurate to the millisecond, has a top-mounted pin for easy access by both lefties and righties, and is multi-purpose (both fragmentation and blast overpressure through a flip of a switch– filling a gap left in the Army’s lineup when the MK3A2 concussion grenade was retired in 1975).

The Enhanced Tactical Multi-Purpose (ET-MP) hand grenade, best yet, will be considered completely safe until armed and will be the first Insensitive Munition-qualified lethal grenade in the Army’s arsenal.

“With these upgrades in the ET-MP, not only is the fuze timing completely electronic, but the detonation train is also out-of-line,” said Matthew Hall, Grenades Tech Base Development Lead, in a release from the Army. “Detonation time can now be narrowed down into milliseconds, and until armed, the hand grenade will not be able to detonate.”

Still, I’m not too sure about giving a grenade multiple choice options that have to be chosen at night in the fight and adding electronics to a basic concept that dates back to the 13th century and earlier.
