I know this is just joking around but wanted to provide some real context. A flare is not something you normally need or use, so they just sit around all the time but when you need one, you REALLY need it to work properly. A 32 year expired flare may work properly but you don't want something to have a 20% failure rate if your life depends on it. Thus the expiration date so you know when to replace them.

Even funnier that said part was the only foreign-made component of the Tigershark (built by Sweden, originally made for their Viggens in the 70s) Edit: to explain a bit, the Tigershark was meant purely as an export aircraft, so majority of its components can't even be ITAR restricted (or else maintainers, technicians, and even pilots from other countries couldn't even get near the aircraft they're supposed to work with/on/around)

[@1lovesoni]

There's so many things that are ITAR regulated but commonly sold/traded, especially in the military surplus world. Some make sense, like military uniforms, ammunition, and laser aiming devices. Other's make significantly less sense, such as optics/scopes that are only popular with civilian hunters/sport-shooters (because the manufacturer has a military contract on a different optic/product and I guess it's feared that they might be potentially similar enough between models). Lastly there are certain items that seem senselessly restricted for US export due to ITAR, including the Sony Playstation 2, random bits of clothing like various belts or socks, and even certain life preservers (yes, the anti-drowning vest type).

Hey Tom, I just want to say that it seems like you're genuinely happy here and it is nice to see. Some of your Ex and Ire posts definitely made it seem like that paper was stressing you out a bit. I just want you to know that you're a damn inspiration, I'm going to be coming from the other side of things, a machinist gone engineer who has always just wanted an excuse to get a physics degree. I'm nearly halfway there now and my goal is to study fusion mechanics which, for much of my life made me think of big magnets. Lately though, one of my local universities unveiled a 3PW laser and they've teased that they might try to help NIF or build a fusion facility to compete with it. So, suddenly the end goal of my degree path is starting to look a lot like yours o.0 Which is also to say that if you're not fully convinced you should come over to the war side of things, I hear that UNSW is building a student led tokamak and I'm sure there will be much lasing to be had in that system as well. If you ever end up working on such a project, I'd be very curious to hear about it! Really though, awesome video, good to see you having a blast as it were.

You're not wrong, that's basically how they started out. Leading missiles into the sun was a legit tactic very early on, because the sun is the biggest hot thing around. It's just then there's been 60 odd years of building on top of that, both in terms of getting the missile to more accurately identify and follow aircraft and in terms of countermeasures manufacturers adapting to missile development.

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 where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event 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 the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows 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.

[@Marin3r101]

​@@wingracer1614 not sure how close to reality War Thunder is for IRCCM missles... but they basically have a number assigned of the brightness of flares vs. The seeker head. A FOV is the prime factor on getting hits, but they can still be tricked if you flare alot in front of them and force the seeker to turn off (the missile will track based off of the historical vector of the aircraft) so if you flare like crazy and they change vector you can evade. No amount of IR camera + software can prevent this. The only thing you can do is make it faster in velocity so it closes the distance in less time or use undetectable systems and go "stealth".

In today's episode, Tom demonstrates a recent college grad approach to budget defense optics helping other recent grads prove their point there should be more security awareness about and better utilization of off the shelf technology.

[@Spearhead-ke8kd]

Should have got some milsim game sponsorship for this one. I would laugh myself to death if I heard you do a War Thunder ad read.

[@merobo5066]

War Thunder players are the type of people who might leak the composition of more modern flares to him

Would have been good to do the road flare with your improvised missile seeker setup just to see whether or not it (the seeker) actually works properly for viewing IR in the desired wavelengths.

[@ExplosionsAndFire]

Yeah, thinking about that now makes a lot of sense

Hmm, I have a formula for an interesting IR flare, if you happen to have some rubidium nitrate laying around.

[@ExplosionsAndFire]

I have rubidium chloride somewhere, so I’m interested??

[@r.awilliams9815]

@@ExplosionsAndFire Rubidium nitrate 60.8, silicon 10, hexamine 23.2, epoxy resin 4.2 (D.E.R. 321) , hardener 1.8 (D.E.H. 14) The epoxy is a very low viscosity resin, so probably not substitute-able. Source - PATR 2700, although I'm not sure of which volume and page number. I found the formula in Donald Haarman's The Wizards Pyrotechnic Formulary.

Aussies are incredible at making military stuff, especially janky stuff that works incredibly well. Like the flatpack cardboard drones, or a 30mm autocannon from an Apache stuck on the back of a pickup truck to shoot down drones. Or the most famous, the Owen Gun: a submachinegun with the magazine sticking out the top

[@cockatoo010]

Air to air AND surface to air! The cheapest weapon that can effectively and consistently shoot down planes are MANPADS and those tend to be IR guided. Plus they can be carried and fired by a single infantryman So you don't have to assume both sides can afford a fighter jet, you can assume one side can afford a fighter and the other has access to MANPADS trough a friendly rival power that has beef with the larger side

[@guytech7310]

Only really effective against attack helicopters as manpad missiles have very limited range. Russia is testing a laser defense system which tracks inbound Ground to Air missiles using a turret on its Ku-52 helicopters. Manpads are also not cost effective against low cost drones like the lancet used for anti-tank (replaceing the need for attack helicopters).

[@mf1ve]

If I've learned anything from a certain Navy CIS episode, it's that if you want a pyrotechnic mix to burn for longer, mix it fire retardant (ratios most likely subject to testing with specific compounds).

[@Cragified]

Against older guidance technology yes this is how it worked. However, modern ones aren't just looking at the infrared spectrum and steering towards it. They can determine the size of the emitting object, the velocity of the emitting object etc. So if you filter out the smaller and slower moving objects then what's left is the desired target (This is ultra simplified). Countermeasure flares today still do have an effect but it's much smaller and need to be deployed in specific ways and in large volumes to do much against say a AIM-9X or ASRAAM. Even the old FIM-92E from 1995 isn't easily distracted by flares (As Russian helicopter pilots found out).
