Microkoneita. Teorisoin näiden tulevan toteen vuosituhannen jälkeen, mutta kesti kaksikymmentä vuotta ennenkuin ne tulivat toteen.

There is a growing need for cost-effective persistent surveillance solutions for multiple platforms, such as UAVs, drones, and fixed- and rotary-wing aircraft. SCD has introduced the world’s first 5-micron, 5 mega-pixel IR detector - the Crane. This breakthrough product is a game-changer in EO/IR applications, offering excellent performance in a small, lightweight, and compact product. The Crane enables persistent surveillance from a cost-effective tactical platform or drone while overcoming the need for multiple UAVs to be deployed, each with its own payload, to cover large areas. Instead, very high resolution can be achieved with just one highly-reliable Crane detector, reducing costs and operational complexity.

Milrem Robotic’s C2 system allows the constant monitoring and controlling of the UxV systems' most important variables, such as energy status, fault conditions, operating parameters, built-in diagnostic tests, initialization, and configurations. The system is developed in cooperation with Fleetonomy.ai, Rait88, MIL Sistemika and other partners.

"Integrating different unmanned systems and traditional manned assets through a command-and-control system enables the efficient deployment of autonomous vehicles on the battlefield," explained Kuldar Väärsi, CEO of Milrem Robotics. "Integrated autonomous ground systems enable a significant increase of firepower and capabilities using fewer human resources and at the same time increasing the safety of our troops, which has always been the goal of Milrem Robotics."

The C2's autonomy engine is capable of remotely navigating and controlling the position and motion vectors of the UxV's and/or other integrated RAS components.

Smash Dragon

Itse olen miettinyt, milloinkohan tämän tapaiset tai loitering munitionit yleistyvät salamurhissa. Israel on tainnut toistaiseksi käyttää iranilaisten ydinasekehittelijöiden yms. eliminoimisessa esim. ajoneuvoon sijoitettuja kauko-ohjattavia kivääreitä.
 
Ovat vain älyttömän kalliita. Jenkit voisivat sijoittaa muutaman tuollaisen (tektissä on typo, MQ-9 ne on) Suomeen ja kerätä datat molemmille, nyt kun ollaan jo Natossakin heti kun vain ottavat.
The US State Department approved the sale of four MQ-5 Block 5 Reapers to Spain for $243 million in 2015. That deal would have included 20 embedded global positioning system and inertial guidance units, two mobile ground control stations, five multi-spectral targeting systems and five synthetic aperture radars. Also proposed was contractor logistics support for two years and personnel training, as well as aircraft components, spares and accessories.

USAF:n suunnitelmissa on integroida lennokkiin myös ilmasta-ilmaan vaikutuskyky.

It sounds like a rhetorical question that a Midwestern engineer might ask, something on the order of ‘can you fix this bad PCB spin?’ [Tom Stanton] sets out to answer the title question and ends up building a working e-bike with a drone motor.

You might be thinking, a motor is a motor; what’s the big deal? But a drone motor and a regular e-bike motor are made for very different purposes. Drone motors spin at 30,000 RPM, and an e-bike hub motor typically does around 200-300 RPM while being much larger. Additionally, a drone motor goes in short spurts with a large fan blowing right on it, and an e-bike motor can run almost continuously.

The first step was to use gears and pulleys to reduce the RPM on the motor to provide more torque. A little bit of CAD and 3D printing later, [Tom] had a setup ready to try. However, the motor quickly burned out. With a slightly bigger motor and more gear reduction, version 2 performed remarkably well. After the race between a proper e-bike and the drone bike, the coils were almost melted.

If you’re thinking about making your bike electric, we have some advice. We’ll throw in a second piece of advice for free: use a larger motor than the drone motor, even though it technically works. Video after the break.

Spike Firefly
SPIKE FIRELFY is part of the SPIKE Family of precision guided electrooptical missile systems, a portable vertical take-off and landing (VTOL) miniature tactical loitering munition designed for ground organic precision strike for close combat forces in any environment.

The weapon system kit includes 3 Loitering Munitions, a Control Unit consisting of a ruggedized tablet and a backpack. The FIREFLY Loitering Munition includes a dual seeker (IR/ CMOS), proximity sensors, military standard bidirectional data link, and a detachable warhead compartment allowing flexibility in training and storage.

FIREFLY’s modes of operation include fly-bywaypoint and fly-by-video, in which the operator controls the LM heading by touch commands on the video itself, allowing intuitive operation. Once targets are detected, whether visible or Beyond Line of Sight, the operator locks onto them and attacks with pinpoint accuracy. The FIREFLY LM can be recalled back to the operator at any time before the final attack command is issued.

The FIRELFY munition includes an advanced multispectral seeker with both uncooled IR sensor, high-definition CMOS day sensor as well as a proximity sensor allowing the system to detect, identify, track & home on very agile targets. In addition to the seeker the munition includes an encrypted data link and a lethal blast fragmentation warhead.

FIREFLY can also be supplied in a vehicle-mounted configuration, designed for IFVs (Infantry Fighting Vehicle). The integrated system enables the launch of FIREFLY LMs from within the IFV. The LMs acts as an armed scout for the armored formation both as an effector for removing threats on the vehicle’s path and as a recon asset for enhancement of situational awareness.

In May 2022, Rafael Advanced Defense Systems and its US subsidiary RSGS demonstrated the SPIKE FIRELFY loitering munition at the U.S. Army Expeditionary Warrior Experiment 2022 (also known as AEWE).

Phobos, UGV

PHOBOS, like a satellite of Mars, God of War, is a remotely operated modular robotic carrier of less than two tons net weight, and with a one-ton payload. It has been designed to accommodate various tools and sensors: surveillance, acquisition, reconnaissance, intelligence, armament, etc.

The two guiding principles of this design are mobility and autonomy. Mobility is reflected in the 4-wheel drive with reinforced suspensions that allow it to easily follow the tracks of armored vehicles in service on the all-terrain.

Autonomy is ensured by a diesel engine and a large tank that supply electrical and hydraulic energy to all embedded equipment. The Phobos can be armed with a rocket launcher made by Thales.
 
Teaming helicopters with drones is nothing new. The Army has paired RQ-7 Shadow drones with its AH-64 Apaches to provide the attack helicopter crews a wider view of the battlefield, for instance. The Army also is testing swarms of loitering munitions, some with warheads and some without, to lead future airborne assault missions. In those tests, the suicide drones fly out ahead of manned rotorcraft to scout potential landing zones, identify targets and engage enemy positions — all the while feeding reconnaissance data back to manned assault aircraft and command centers — in preparation for inbound troops.

Adopting loitering munitions that can be controlled by land, sea and airborne platforms adds another dimension to what capabilities UAS bring to modern combat operations. For the Marine Corps, a system like the Hero 400, with its range and endurance and the ability to transfer control between platforms, provides significant mission flexibility. That aligns with the Corps’ plan to restructure as a lighter, more agile maritime force under the Force Design 2030 initiative.

Ayala and other Marines from Marine Aircraft Group 39, attached to 3rd Marine Aircraft Wing, and 1st Reconnaissance Battalion, attended a Hero Aerial Loitering Munitions and Effects (ALME) introductory training course at Camp Pendleton, California. Led by UVision-USA instructors, the course provides hands-on and simulation training with the UAS and its control system.

The two-week course was condensed into a one-week crash course so the Marines could establish a working knowledge of the system before the real-world trial, Ayala said. At the end of the week he was confident in his ability to remotely pilot the Hero 400EC from anywhere.

Predator ja irakilainen Mig-25 kävivät ilmataistelun ohjuksin 2002.

Predatoreihin oli pikaratkaisuna asennettu Stingereitä itsepuolustukseen. Video tapauksesta löytyy yhä netistä. Kumpikin laukaisi yhden ohjuksen. Stinger suihki ties minne ja Predator tuli tonttiin.

Toisaalta 20 vuodessa tekniikka ja kokemus kehittyvät. Nyt voisi käydä vähän toisin. Toki tuollainen UCAV on joka tapauksessa usein hidas maali.
 
Miten olisi Drone risteilyohjustorjuntaan? Dronet voi pysyä ilmassa melko pitkään ja olettaisin että ilmasta on helpompaa havaita ja torjua risteilyohjuksia. Niitä voisi sitten laittaa pörräämään esim. maantietukikohtien ylle suojaamaan hävittäjiä.

Ei riitä vauhti nykyisillä vehkeillä, mutta teoriassa mahdollinen.
