Designing Large Drone Weapons Systems in Australia

The Australian Government yesterday announced it will spend $1.7bn on a fleet of several dozen Ghost Shark submarines. These will be uncrewed, and made in Sydney by US company Anduril. This received limited media coverage as most of the capabilities and some of the purposes of the submarines are classified. I was asked to talk about this on ABC Radio Nightlife with Philip Clark at 1 am.

At  approximately 5.8 m, the Ghost Shark is one third to one quarter the length of the USA's Orca extra-large unmanned undersea vehicle (XLUUV). The Australian vessel has the advantage of being about the size of a standard shipping container, so it can be transported by truck, train, ship or aircraft. 

The range and power source of the vessel are classified. A reasonable guess is that initial units are powered by lithium batteries, with a diesel engine, which the Orca has,as a later option. Range is likely to be around 1,000 km, far less than the 10,000 km of the Orca, but still with an endurance of several months. These type of XLUUVs are not built for speed, as evidenced by the bulky shape. 

These XLUUVs are likely to be used initially for surveillance, mapping, and patrolling fibre optic cables. They are too small to carry the heavyweight torpedoes used by crewed submarines and too slow for topedio attacks. They are also too small to carry ship or land attack missiles. While minatore torpedoes and missiles are available, the sea mine is likely to be the primary weapon. Australia has already taken delivery of smart sea mines from RWM Italia. These could be laid by the Ghost Shark outside harbours and approaches, programmed to allow civilian to pass, to enforce a blockade.

Australia is also cooperating with Boeing on the MQ-28 Ghost Bat, a moderately stealthy, uncrewed combat aerial vehicle (UCAV). The Ghost Bat has been quietly under development, but came to prominence recently, when Boeing offered it to Poland, to complement F-15 crewed aircraft. The person in the rear seat of the F-15 would control multiple Ghost Bats, each armed with missiles. The  Ghost Bat could also be used to protect surveillance and tanker aircraft, while being controlled from them. Like the Ghost Shark, the Ghost Bat is small enough to be transported easily by road, sea or air. 

Ghost Gecko Concept

A third arm not yet announced for Australia defence is the land equivalent of the Ghosts: a robotic land vehicle. To fill that gap I speculated about a "Ghost Gecko", an Uncrewed Ground Vehicle (UCV) for the Australian Army. This  would be derived from the Hawkei four-wheel-drive protected mobility vehicle. The crew cab would be removed, to lighten the vehicle, and lower its profile. In its place would be an Australian made remotely controlled weapons station (RWS), with a cannon and missiles.

The main area for research and development of these platforms is not the hardware. The problem is the level of autonomous control available. Submarines cannot easily communicate when underwater. The Ghost Shark will need to be able to make decisions itself. The Ghost Bat can be communicated with more easily, however ione operator may be controlling multiple aircraft simultaneously, so a level of autonomy is still needed. Land vehicles have fewer issues, except where large numbers are used. These are issues which are addressed in computer and engineering departments of universities world wide, including in Australia.

Using an Android Phone as a Desktop Computer

After years of trying, yesterday I was finally able to plug my generic Android phone into a monitor, keyboard and mouse, to turn it into a desktop computer. This was with a Unihertz Atom L phone running Android 11, a second hand Dell D6000s Usb-C Docking Station and an unbranded USB-A To USB Type C OTG Adapter.

First I installed  Synaptics' free Displaylink for Android app. Then I plugged a Dell power supply, mouse, keyboard and monitor into the docking station. I inserted the USB-A plug of the station into the OTG adaptor and the adaptor into the phone. After some head scratching and rebooting the phone, I was asked if I wanted the display sent to the dock. 

The phone display on screen looks like a giant portrait phone display. So I then needed to set the phone to the smallest font, and rotate it to horizontal, so it matched the screen. Within an application, such as web browsing or Google Document, the mouse and keyboard worked fine, like a desktop application. But for moving between applications I used the phone touchscreen. If you need to bash out a book chapter, this would be fine. But you would not be wanting to be working between applications.

The docking station plus power supply is much larger than the phone and there are a lot of cables. This would be fine to leave on a desk, but a nuisance if carrying around. There are smaller adaptors, but do they use DisplayLink? Also the station doesn't charge the phone via the USB cable (there are OTG adaptors which allow you to inject power, but I bought the cheapest one). 

Google are working on a desktop mode for Android, currently in Beta for version  16. This will make it much easier to use applications on a large screen. For non-power users, this should be sufficient. You would just plug one cable into your phone and be in desktop mode.
