Meanderings of a Weapon Oriented Mind When Applied in a Vacuum Such as on the Moon

meanderings-of-a-weapon-oriented-mind-when-applied-in-a-vacuum-such-as-on-the-moon

The Aerospace Projects Review Blog uncovered a great July 1965 report from the U.S. Army’s Directorate of R&D Future Weapons Office about the realities of using firearms and other projectile weapons in space.

Conventional firearms would work just fine in space… at least for a while. A vacuum would cause most lubricants to outgas and turn to waxy solids or hard rubber-like crud. The extreme differences in temperatures between sunlit and shaded would cause many metals to warp and mechanisms to seize up. And there’s always the possibility of vacuum welding, where two similar metals will simply stick together, fusing into one. And recoil that gives a shooter a good kick on Earth might knock them over on the Moon, or send them tumbling in freefall. The authors described these problems and pointed out potential solutions. Additionally, they provided a number of notional concepts for hand-held weapons, ranging from modifications to the normal sort of firearm, to guns powered by springs (with, it must be said, rather optimistic muzzle velocities) to gas-guns and handheld mini-rocket launchers.

Such as the Sausage Gun!

More on the Proteus mini-sub

Huntington Ingalls Industries just dropped a new video hyping their swag prototype Proteus DMUV (dual mode undersea vehicle– they really need to fix that acronym) which they hope will replace the vintage MkVIII “Eight Boat” SDV (frogman sub) in use by NSWG. Sure, its a little over the top with all the cheerleading by people really happy to be part of the team building experience they can pop in on their LinkedIn page, but there are lots of shots and a little background on the Proteus. Dig those interfaces.

Sea Hunter takes her TALON out to play

We’ve talked about DARPA’s 132-foot USV robot subchaser, the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV), dubbed Sea Hunter, a few times already this year.

The ship’s projected $20 million all-up price tag and its $15,000 to $20,000 daily operating cost make it relatively inexpensive to operate. For comparison, a single Littoral Combat Ship runs $432 million (at least LCS-6 did) to build and run about $220K a day to operate– but of course that is a moving target.

We’ve also talked about their Towed Airborne Lift of Naval Systems (TALONS) U-boat kite program which is a low-cost, fully automated parafoil system designed to extend maritime vessels’ long-distance communications and improve their domain awareness.

Towed behind boats or ships, TALONS could carry intelligence, surveillance and reconnaissance and communications payloads of up to 150 pounds between 500 and 1,500 feet in altitude—many times higher than current ships’ masts—and greatly extend the equipment’s range and effectiveness.

So it makes sense that now video has emerged from DARPA of Sea Hunter taking its para-sail for a drag.

Now if they Navy can just cough up 50-100 of these, with ASW weapons and an automated C-RAM to avoid being splashed by enemy aircraft wholesale, and keep it from running $30 billion– then you have a real sea control ship when it comes to denying an area to the bad guy’s subs.

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:

left-grenade

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.

new-grenade

“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.

And her name shall be Sea Hunter

Just unveiled a few weeks ago, the 132-foot USV which aims to be the Navy’s newest 21st Century expendable sub-chaser has been formally christened.

sea hunter

Part of the Defense Advanced Research Projects Agency (DARPA)’s Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV Pronounced “Active,” ) program, in conjunction with the Office of Naval Research (ONR), Sea Hunter as she is now know, is a game changer.

“This is an inflection point,” Deputy U.S. Defense Secretary Robert Work said in an interview, adding he hoped such ships might find a place in the Western Pacific in as few as five years. “This is the first time we’ve ever had a totally robotic, trans-oceanic-capable ship.”

Sea Hunter will now move to San Diego for a two year pilot program to R&D just what the platform can do and what sensor package works best.

The ship’s projected $20 million all-up price tag and its $15,000 to $20,000 daily operating cost make it relatively inexpensive to operate. For comparison, a single Littoral Combat Ship runs $432 million (at least LCS-6 did) to build and run about $220K a day to operate– but of course that is a moving target.

Still, its easy to see where a flotilla of Sea Hunters could provide a lot of ASW coverage on the cheap and even if mines or torpedoes take half of them out, it’s a hit to the treasury and not incoming C-17s to Dover with waiting honor guards.

And with that in mind, check out this super sweet walk-through/construction video to see just how simple this craft is.

Meet ACTUV

DARPA just released some neat but brief 360-view footage of their Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) including some of it underway at a good clip (27 knots). The 132-foot USV is meant to be the expendable subchaser of the 21st century, and actually looks pretty sweet.

If they can get past concept and put 50-100 of these cheaply in the Western Pac, networked all sweet to a central ASW War Room, it could really negate all the skrilla the Norks and PLAN are dropping on subs.

Meet Squad X

SquadXConceptMontage

DARPA is pushing ahead with a brave new world of innovative concepts for the future dismounted Army and Marine squad/section/fireteam in what they term their Squad X Experimentation.

The program intends to lay the foundation for breakthrough technologies and capabilities that would:

-Improve shared situational understanding of the multi-domain operational environment: physical, electromagnetic and cyber.

-Increase the time and space in which squads can maneuver through optimized use of physical, cognitive and material resources.

-Shape and dominate the battlespace through synchronization of fire and maneuvering in all three domains.

“Through Squad X, we want to vastly improve dismounted squad effectiveness in all domains by integrating new and existing technologies into systems that squads can bring with them,” said Maj. Christopher Orlowski, DARPA program manager. “The squad is the formation with the greatest potential for impact and innovation, while having the lowest barrier to entry for experimentation and system development. The lessons we learn and the technology we create could not only transform dismounted squads’ capabilities, but also eventually help all warfighters more intuitively understand and control their complex mission environments.”

Imagery released in association with the program, for which they intend to hold a Proposer’s Day next month, show Joes/Devils outfitted with next gen armor, carrying M4/416-ish looking small arms, using small multi-rotor UAVs to sense bad guys through walls, have gear packed by robotic mules, popping enemy UAVs out of the sky with tiny guided missiles from a underslung grenade launcher (PIKE anyone?) , and are driven around in armed/autonomous LTATV quads.

Meet Seagull, Israel’s new USV robot boat

seagull

Elbit Systems has a new 40-foot unmanned surface vehicle, the Seagull, which is designed to operate in pairs for either mine sweeping or sub busting. The idea is the first vehicle will have surveillance gear to find the sub or mine, while the second will carry either clearance gear (an ROV) or a anti-submarine torpedo to shove right up the sneaky U-boat’s kisser.

seagull 2 sea gull 3

From Elbit’s presser:

Drawing on world class know -how derived from generations of Unmanned Aircraft Systems (UAS) design, development and operation and its naval capabilities, Elbit Systems’ newest offering in the unmanned platform field is Seagull -an organic, modular, highly autonomous, multi-mission Unmanned Surface Vehicle (USV) system.

Seagull is a 12-meter USV with replaceable mission modules, with two vessels capable of being operated and controlled in concert using a single Mission Control System (MCS), from manned ships or from the shore.

The system provides unmanned end-to-end mine hunting operation taking the man out of the mine field. It provides mission planning, and on-line operation in known and unknown areas,including area survey, search, detection, classification, identification, neutralization and verification. It is equipped to search the entire water volume and operate underwater vehicles to identify and neutralize mines.

The idea is the two-boat pair can operate within 50-100 miles of the control station and remain at sea for 96 hours, covering a pretty large swath of littoral in the process while their operators sip coffee back in a trailer somewhere. A second set of boats can be kept ready to rotate out the first, making a persistent sea station a very possible endeavor.

This obviously has uses in a MIUWU or PSU augmentation or replacement.

Speaking of which, DARPA’s Sea Hunter–the Anti-Submarine Warfare Continuous Trail Unmanned Vessel, or ACTUV is the U.S.’s version of this, and is mucho larger at some 132-feet long and is getting some love on social media as of late.

That’s pretty fast for an autonomous backpack UAV

DARPA’s Fast Lightweight Autonomy (FLA) program recently demonstrated that a commercial quadcopter platform could achieve 20-meters-per-second flight while carrying a full load of sensors and cameras.

So what’s the big deal?

Well, that’s 45mph in a small (fit through a window or doorway) drone. And by drone, we don’t mean remote control quad, the project is seeking to have a completely autonomous unmanned aerial vehicles to fly at speeds up to 20 m/s with no communication to the operator and without GPS.

Nothing like clearing a building via remote which will save the lives of Joes and Marines in the long run.
