US Navy Swarm UAVs

The U.S. Naval Air Systems Command (NAVAIR) recently demonstrated autonomous operations by multiple “swarms” of unmanned air and ground vehicles, unattended ground sensors, video cameras and other devices linked together in an intelligent network powered by EdgeFrontier platform technologies from Augusta Systems, Inc.

Basically using one operator to control a fleet of aircraft.

The RAF did tests on swarm UAV operations from an airborne controller in a Tornado in 2007 using QinetiQ technology called Autonomy

I wonder if they were using the fluid dynamics model to control these swarms?

Why computers suck at maths

This article explores why computers can’t do floating point maths, which is what makes Excel and all those online calculators such lousy mathematicians – basically because computers are binary, they can’t calculate anything after a decimal point, so the workaround is to put the number including the decimal point in a register of a certain size (say 32 bits) and reserve a few parts of the register for the decimal. Should the number you need to calculate become too big for the register, you run into trouble with rounding errors, which can compound. It then shows how nasty compound errors can become by citing the example of why a Patriot missle battery missed a Scud attack, resulting in the deaths of 24 people.

Soviet Doomsday Machine

Apparently the USSR actually went and built a doomsday machine – something that would launch command missles which would transmit coordinates to other ICBMs in the event that the Soviet Union was destroyed. The system, called ‘Perimiter’ and known as ‘Dead Hand’ basically ran through some checks and then delegated launch authority to whoever it could reach.

The Soviets kept this a secret as their principle use for the system was not deterrence towards the US, but to calm hotheads in the Soviet military and to stop them from throwing up independant first strikes when the going got stressy, as the hotheads knew that if the USSR went down, they’d get their revenge.

Dutch JSF buy based on unreal figures

The Dutch ministry of defence has apparently known since 2005 that the budget reserved for the JSF buy (to replace the KLu F-16 fleet) was in nowhere near enough for the planned 85 F-35s they needed. The Dutch MOD has answered parliamentary questions about this with the statement that they expected a budget increase and that this is why they’ve never mentioned the budget shortfall.

So basically the Dutch MOD and KLu have been supporting a fighter buy they knew they couldn’t afford and have been throwing sand in the eyes of the parliament and are now scrambling to cover their arse.

F-22 chopped by US Senate

The US has just gone and done something I really can’t see the point of besides politics: they’ve gone and chopped their air dominance fighter after a production run of under 200 aircraft.

Instead they want to lay their eggs in the F-35 JSF basket – which performs poorly against the current Australian F-18s and will be chewed up by mostly anything the Soviets have as well as the Eurofighter, Gripen and Rafale. Does the US really want their air cover to be provided by the next generation F-16: a poor man’s jack of all  trades but master of none? Yes, right now there aren’t many threats against the F-15C and F-18E/F but the Su-30s will spread through the world, and they do eat these aircraft for breakfast. Without a counter like the F-22 you can’t own the air space. Without air space, your military options are severely limited.

US Missle Sheild Upgrade

The missile shield will be upgraded by multiple kill vehicles being carried up by as a single payload in a rocket. There are two competing tenders: Lockheed Martin and Raytheon. Lockheed guides the mini rockets from a central command unit, Raytheon’s system has each of the warheads acting as a seeker / controller in theory, but one of them becomes a master after launch and transmits the targetting plan to the other vehicles.

JSF doesn’t do too well

The Royal Australian Air Force (RAAF) staged an excercise pitting the JSF against the 4th generation russian fighters and it got it’s arse handed to it in the turning game. Link goes to the movie. Memorable quotes are:

“The report says the JSF is: “‘Double inferior’ relative to modern Russian/Chinese fighter designs in visual range combat.” And has “Inferior acceleration, inferior climb, inferior sustained turn capability.”

It concludes that the JSF: “Can’t turn, can’t climb, can’t run.”

and dogfighting it is:

“like clubbing baby seals”

I’ve been saying it enough – JSF is a dud!
