40 years ago I took delivery of a box at my place of business in Belfast. I was expecting a resin sample from a chemical company and the box arrived by conventional courier. Instead it contained multiple carefully packaged cylindrical electronic devices. The address label for my firm had been stuck over the original destination "Short Brothers", a local defence contractor. The contained covering letter revealed the sender to be Graseby Dynamics, an English defence contractor, and the contents were described as the revised design of the Javelin missile warhead firing mechanism. I contacted Shorts and the police. and within 30 minutes my premises were crawling with plain clothes state security. The items were taken away and I was interviewed at some length. Somehow the press got hold of the story and it made the front page of the local paper. My business partner was by coincidence a friend of a department head in Shorts. He later revealed that a government junior minister had lost his job over this, and there had been several individuals severely disciplined both at Shorts and Graseby. I never did get my resin sample.

It's a 1980s design. Everything used was the absolute state of the art at the time, and from what I read there were a lot of problems with it. Even the most modern version has unresolved issues. The biggest part on the board with the DSP is most likely a TMS34010, a general-purpose 32-bit CPU with special graphics instructions which was just going into production back when this was being developed. The IDT parts on a few of the other boards are most certainly dual-port RAMs and the VLSI chips will be custom glue logic.

Hey, overall as I've watched the Ukraine War I have been researching and learning obsessively about every weapon system in existence.... The thing I don't understand is with the advancement of technology, microcontrollers & especially computer vision object tracking available to the market nowadays, wouldn't it be possible to MASS PRODUCE something similar to a javelin for less than $2,000? **(A daytime version at least)? I understand a high-end Mid Wave Thermal IR Image Seeker operating at 60-120FPS would be ITAR restricted & add $10k to the overall cost but, still should not cost more than $15k total today... It seems like most of the cost associated with these guided systems is the software and algorithms....

@@justinhealey-htcohio3798 electronics and cameras did get cheaper over years and you could possibly improvise something with consumer grade parts.

[@deang5622]

It's probably an orientation sensor so the missile knows which way it is pointing when it can't see the target. The missile trajectory is that it climbs up at a steep angle (in one of the modes of operation) and then pitches down and attacks the tank from above where the armour is thinner, and using infrared targeting. I suspect when the missile is in the climbing phase of its flight, the infrared seeker is not pointing at the target. So in this phase of flight, the infrared seeker head cannot see the target and cannot be used for control and guidance of the missile. The missile needs to know the pitch angle it is currently at so it can then be steered back down towards the target and the infrared seeker will be used to guide the missile in the terminal phase of flight. Just a theory

Hello do you still have your work on the flir lepton ?

I used to work for an avionics contractor. It’s interesting how similar this is to modern hardware … yet also very different. Everything has FPGAs with 16-layer conformal-coated boards. It all has a 1553/1760 bus with expensive parts and a lot of redundancy (compared to consumer stuff). But look at all those ribbon cables and interfaces! In 2007 we were already working on 16Gb fibre interfaces because the F-35 needed the bandwidth. But many years before that we were making missiles with a lot more resistance to EMI than this appears to have. But it’s a funny mix of new and old. I used to have to look up specs in manuals from 1973.

* The pink stuff gluing the metal plate to the carbon fiber body tube is heat transfer paste. * Those large VLSI parts are gate array parts rather than FPGAs. Gate arrays are midway between full-custom parts and FPGAs. VLSI used to make gate array chips where the silicon and maybe 1 or two metal layers were standardized, but the top couple of layers of metal were customized. So for the price of taping out (and making masks for) two metal layers, you could get a part with 100x the gate count of an FPGA, without having to pay the full cost (and manufacturing delay) of a full-custom 3-5 metal layer part. * Hardly any heat sinks! Most of this stuff didn't run long enough to get hot. Must of been a PITA to debug, since it probably got pretty hot during a debug session.

[@patman0250]

The components in here are not extremely expensive at all. The chips and electronics are dirt cheep. The reason why these things cost over $100,000 is because it's a problem that the department of defense has been dealing with for a long time. It's called price gouging! You see these missiles probably cost anywhere from 5000 to 10000 to make. But they're going to sell it for hundreds of thousands of dollars because they set the price and they know that the governments going to pay up. The Pentagon gets priced gouged on everything, from office supplies toilet paper to missiles. We're talking about pins that cost less than a dollar getting charged $80 per pin and over $100 a toilet roll. Lockheed Martin, Raytheon, Boeing, Northrop, Textron and more. All of them price gouge the hell out of the taxpayers it's the biggest scam nobody ever talks about. It's basically why we have to pump so much damn money into defense because the United States it's basically getting scammed by United States companys.

[@HrDoktorBillerbeck]

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is - whichever is greater - it obtains a difference or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position that it wasn't, it now is. Consequently, the position where it is is now the position that it wasn't, and if follows that the position that it was is now the position that it isn't. In the event that the position that the position that it is in is not the position that it wasn't, the system has acquired a variation. The variation being the difference between where the missile is and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows: Because a variation has modified some of the information that the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it know where it was. It now subtracts where it should be from where it wasn't, or vice versa. And by differentiating this from the algebraic sum of where it shouldn't be and where it was, it is able to obtain the deviation and its variation, which is called error.
