The “SPICE” (Smart, Precise Impact, Cost-Effective) is an Israeli-developed, electro-optics/GPS guidance kit for converting unguided bombs into precision guided bombs. The Spice 1000 is often employed for US-made MK-83 unguided bomb, which has the weight of about 450 kg.

lol now thats what i call quick Technology Transfer lol
Free of charge as well :)
Ship it to Iran … Don’t waste time……
call in the Russian and Iranian expert . and jontly develop tighter with Syrian . use this technology against this zionsit
spice girl
Pathetic. Israel just made a free trade zone with Ukraine. Russia begged Israel to not bomb Damascus International airport, where after Israel did just that. Russia and you controlled opposition are left to copy Israel´s garbage pieces…………………..LOL. https://www.youtube.com/watch?v=ujkxoMYrGPc
SPICE “Syria Provides Iran Circuit-board Equipment”
AHAHAHAHAAHAHAHAHAHAHA TRUE!!!
They can, whether or not its still useful remains to be seen.
Simulation Program with Integrated Circuit Emphasis Developed by Berkeley University
Wouldn’t it be ironic if these were copied and used successfully against Israel….
What goes round ,comes round. I would think that China will be very interested in the specifications as well as Iran, Russia and North Korea :)
They can pass the chips to the Iranians who make them the same.
Hmm, I think I saw Sukhoi jet in the above video on the Israeli side…
Good god! It’s CE certified!
So they are Safe, healthy and environment-friendly. Can’t say that’s the first impression I get from a weapon, but that’s just me. I’m weird like that.
Now seriously, an electronic board with a CE mark on it, it has to be commercially available. I’ll probably dig into that. With an Arduino and some of it’s peripheral parts, like GPS chip and gyro module, we can build a guidance unit very cheaply, though not as reliable as military grade.
If you apply some TEMPEST technology on the circuit will become military grade as far EW resistant goes.
Nice catch…these things are basically a bolt-on kit for an air dropped bomb…those wings on the side pop out after being dropped by the aircraft, which enables it to glide for up to 60 km…however if we assume its glide ratio is 20 [a fairly high glide ratio] it means the aircraft dropping it would need to be flying at an altitude of 3 km, in order for this thing to glide 60 km…that’s a height of about 10,000 ft which means the aircraft is quite exposed that high and not able to hide in a mountain rift for example…it should be a sitting duck for an s300…
There are 3 types of Spice: 1000, 2000 and 250, each number for the weight of the bomb in pounds they bolt the kit on except for 250 which is a whole 200 lbs bomb. They claim if the bomb is released on altitude of 12000m the glide range is almost 100km, 12 to 100 or about 1:8.5 so to glide 60km they have to be released ~5.5 km (it’s not linear because of air density). I don’t have the specs and dimensions to calculate wing area and the lift it generates (still bot precisely because I still don’t know the wing profile) for each type, but 1:8.5 seems right for 250, I can’t be sure for 2000 but estimate it’s range can’t be more than 60km released at 12km altitude.
The weapons system officer has the ability to maneuver in real time, which means a 2-way connection to the bomb, where EW and jamming comes forward. If the above mentioned bomb’s electronics are intact or at least some parts of it that matter, their frequency range can be determined for future defence.
Thanks for those numbers…a glide ratio [aka lift to drag ratio] of 8.5 is not great…for comparison, a passenger jet is going to be right around 20…that’s why I guessed that a glide bomb would be in that range, since the bomb would be released at about the same speed, high subsonic…ie around M 0.8, the typical cruise speed of a passenger jet…a glide ratio of 8.5 is about that of a small propeller aircraft like a Cessna…a good sailplane will easily go over 30 or 40…
Also you mentioned the ‘man in the loop’ feature which is enabled by the onboard optical sensor [camera]…this is indeed handy…but the obvious vulnerability is the radio signal between the aircraft and the glider…this would not be difficult to suppress, since the small size of the glider means it cannot carry a lot of electrical power…hence the signal is by necessity weak…the same goes for satnav guidance [GPS, Glonass]…it would be necessary only to jam near areas you are trying to protect since cutting off the satnav and man in the loop guidance in the terminal phase basically makes the thing useless and almost guarantees a miss…that one they recovered intact was likely jammed…in fact since these are basically a radio controlled model [only the guy flying it is in an airplane, instead of on the ground]…it should be possible to actually take it over…and land it intact like the Iranians did with the R170…the fact that the radio signal is encrypted doesn’t make it immune from commandeering…it can simply be overpowered…
But like I observed elsewhere…the main problem is that Syrian air defense crews are sloppy…this tendency goes back a long time…
Funny is, the real glide ratio is even lesser than 8.5, since the bomb is released in a ballistic trajectory, meaning the bomb gains altitude after the release and naturally goes over a larger distance.
There are a number of parameters resulting in low glide ratio. The wings of the kit are very small and a pop-out wing also means that it’s airfoil can’t have a great camber and the wings also can’t be longer than the distance between the bomb’s center of mass and it’s rear end which as you know both reduce lift. Add to that the relative density of the bomb compared to a jet liner (more mass per volume). I think that’s the reason they added 4 winglets in form of an X (with sharper angles over horizontal plane) in front of 1000 and 2000 models, instead of a 90 degree X or +. This shape contributes more to overall lift but also adds to the drag of the plane carrying it and limits it’s maneuverability. From the pictures I can’t be sure if the wings have incidence or not. My guess is the whole system acts more like a kite than a glider.
Despite all the hypes about them, it’s nothing fancy but overall it’s a good system to turn dumb bombs into precision stand-off weapons.
Syrian air defence is doing a good job, cut them some slack my friend. Their loss is minimal considering the conditions but if they wasted more than a minute to move the truck after their ammo finished, I agree that they made a costly mistake. In a saturated situation even a few seconds after you spend your ammo is enough to be targeted by the next projectile.
Okay…so a couple of points here…the mass or weight of the glider does not affect glide ratio, only the best glide speed…that is why sailplanes carry water ballast…the extra weight increases the sink rate, but since the glider is moving faster it covers more ground…so the glide ratio remains exactly the same, just the glider gets to the finish line sooner if it is a competition…it is the same in powered aircraft…your airplane’s operating handbook will tell you best glide speed at various weights…the heavier the aircraft weight, due to fuel carried or passengers, the higher the best glide speed…but glide ratio does not change due to weight…so in comparing the glide bomb to an airplane it does not matter that the bomb may have a higher wing loading…ie aircraft weight divided by wing area…a Boeing passenger jet has a wing loading of over 150 lb per square foot…while a single engine Cessna has a wing loading one tenth of that…about 15 lb/ft^2…yet the Boeing glide ratio is nearly double…so weight and wing loading does not come into it…it is about reducing drag by having a clean shape…
Here is the formula for maximum lift to drag ratio [maximum glide ratio]… L/D max = 1/2 * sqrt [pi * AR * e / CD zero] …where CD zero is the drag coefficient at zero lift…ie the basic airframe parasite drag…AR is the wing aspect ratio…and e is the span efficiency factor, which which is unity for a wing with the ideal elliptical lift distribution…
so we see that it comes down to two things…the wing aspect ratio, and the zero lift drag coefficient…that is why gliders have a very long wing [high AR] and a very slim and clean fuselage [low zero lift drag coefficient]…looking at the spice it does not look so bad…the 1000 model is based on the Mark 83 1,000 lb bomb which is 10 ft long [the one in the picture above says MK 83]…so just eyeballing that spice it is certain that the wingspan is at least 10 ft…the diameter is 14 inches…and it is clear that the wing chord is less than that, call it 10 inches [the picture at the top is nice, we clearly see the wing chord in comparison to the bomb diameter…so aspect ratio is 120 inches [ten ft] divided by 10 inches =12…at least [the wing is actually nicely tapered from root to tip…so that is a minimum aspect ratio…with that high aspect ratio, the glide ratio shoul be high…closer to 20 than to 10…even a hang glider has a glide ratio of ~15, with aspect ratio under 10…
Now we can take a shot at trying to estimate the actual glide ratio…let’s assume a span efficiency of 0.9…the zero lift drag coefficient of a clean airframe is under 0.02 [even a small Cessna is going to be about 0.25, and a passenger jet is going to be about 0.015]…but let’s say 0.02…
Those conservative assumptions give us a glide ratio of 20…sqrt [12 * 3.14 * 0.9 / 0.02] * 0.5 = 20.6
So looking at the pictures of that spice 1000 above and knowing the dimensions of the Mark 83 [it is completely intact in the first photo above]…it is hard to see how this flight vehicle is going to have a glide ratio much under 20…if anything, it could be higher, since our estimates above have been very conservative [for instance, the aspect ratio looks to be higher than 12, that is a long slender wing]…
Here are some references you can use to do your own analysis…the FAA Glider Handbook https://www.faa.gov/regulations_policies/handbooks_manuals/aircraft/glider_handbook/ … Lift to Drag ratio… https://en.wikipedia.org/wiki/Lift-to-drag_ratio …zero lift drag coefficient… https://en.wikipedia.org/wiki/Zero-lift_drag_coefficient … span efficiency factor… https://en.wikipedia.org/wiki/Oswald_efficiency_number …a graph from the glider handbook on best glide speed… https://i.postimg.cc/9z3Z04dm/glide-ratio-best-glide-speed.jpg …and the companion graph showing the glide ratio remains the same with added weight… https://i.postimg.cc/t4jvmJKG/glide-ratio-water-ballast.jpg
Thank you for the time you put into the effort. AFAIK, 1:10 is considered an extremely well glide ratio for a glide bomb and no one exceeds that. Indians came close but with the use of a SRB, so not really glide. We can’t get useful numbers from a bunch of pics, without measure reference.
Lol.
I thought the same thing, you could track down that manufacturer and, oh so many options.
Iranians and Chinese are experts in quick re-invention.It will take Iran 3 days to build counter best messiles.Russia will wait for western partners in crime to apologize or use it as bargaining chip.
Russians reluctance have help western partners in crime to infiltrate Soviet and destroy it from inside.That is how great Soviet fall.
lol but how many planes did they shoot down?
They shot plenty of those crappy US supplied missiles down!
lol, how many wars have you won?
We defeated Russia and will do it again
lollolololloollolololllool.
never write in rage AND never write after taking a hit from the pipe.
short sell , the Israeli airlines now before the civilian airport wars begin. that threatened counter attack on the Jews main airport could be the real deal. they must be scrambling to defend, Tel Avia airport today.
Just a few attacks on Israeli airports would ruin the tourist trade :)
If you think that is all that would happen you don’t know the Israelis. They would be fleeing em mass back to the countries they came from. It’s one thing to be shooting unarmed protesters. It is an entirely different thing to be threatened themselves.
Bombs hey, that means it wasn’t just the Pansir attacked by a drone, these would have been dropped from a drone as well. I wonder how low a drone could fly and successfully drop this payload, low enough to evade Syrian and Russian radar, at least until it was too late to stop them. The video of the Pantsir strike was performed at a seemingly low speed, at least I thought it was, I’m wondering if the Israelis are now employing low altitude, radar stealthy drones for these attacks? A combination of Aircraft and cruise missile strikes followed directly by force of low altitude drones could possibly fool even the Russian radars couldn’t they. I think the Israelis have developed a new tactic they can employ against Russia and Syria, and a brand new drone to pull it off. No drones were shot down, just missiles, the one that struck the Pantsir was flying at low speed and over Syrian territory, but it wasn’t shot down even on it’s return flight to Israel [unless it was hit and then fell in Israel], but no other drones were hit and recovered, and to have had bombs dropped you have to have either Jets or drones, we know there were no jets over Israel, they wouldn’t take the chance with a manned aircraft, I think that newly developed low altitude drones are now the Israeli weapon of choice. I wish the Russians would release more details.
It would have to be a large drone to carry 500 kg. So hard to keep it stealthy unless you spend a lot of money and time in design. Carry one munition on center point ?
They already have one, Green Dragon. “This demand will probably be met by a design that has earned the name “Flying Elephant,” designed by Israeli drone manufacture. The Flying Elephant, designed to carry 500kg, consists of a motorized parafoil with servo systems”. Maybe they have one that can carry a 1000 kg payload now, but just one 500 kg bomb would be enough if it was also stealthy and could fly at low altitude. https://breakingdefense.com/2018/03/israeli-ground-units-building-drone-air-force/
this one?

a 16 Kg drone lifting a 500Kg bomb?
Sorry, I accidently called the new 500 kg capacity drones the Green Dragon, that should have been the Flying Elephant, “This demand will probably be met by a design that has earned the name “Flying Elephant,” designed by Israeli drone manufacture. The Flying Elephant, designed to carry 500kg, consists of a motorized parafoil with servo systems”.
“Bombs hey, that means it wasn’t just the Pansir attacked by a drone, these would have been dropped from a drone as well”
The bomb itself weights 1000lbs, plus the guidance kit. Drones cannot lift even one of them.
This article is from way back in 2011, there are a few from 2012 as well, but none after those until this latest article from 2018. A more powerful Flying Elephant UAV to carry out flight tests A new version of the Elbit Systems/ Bluebird Flying Elephant cargo-carrying unmanned air vehicle is set to carry out flight trials in the coming months.
The programme was initiated by the Israeli Defense Forces (IDF) to enable resupply missions to support frontline combat personnel. A new variant with increased power and payload capacity is being developed.
The 100HP engine used in the previous prototype has been upped to 300HP and the 500kg payload has been tripled to 1,500kg. The payload is carried on a shock-proof pallet system. The Flying Elephant is a motorised parafoil with servo systems to retain its aerodynamic shape. A GPS system navigates the UAV. BlueBird has adopted advanced para-wing technology to enable the UAV to achieve a speed of up to 45kt (83km/h), with the design to be capable of being flown in harsh weather. The problem of resupplying Israeli combat units became acute during the second war in Lebanon, in 2006 and Elbit was selected to develop the system in 2011. http://www.uavexpertnews.com/2016/03/more-powerful-flying-elephant-uav-to-carry-out-flight-tests/ This next segment comes from a 2018 article. “This demand will probably be met by a design that has earned the name “Flying Elephant,” designed by Israeli drone manufacture. The Flying Elephant, designed to carry 500kg, consists of a motorized parafoil with servo systems”. http://www.uavexpertnews.com/2016/03/more-powerful-flying-elephant-uav-to-carry-out-flight-tests/ …. So back in 2011 the Israelis had resupply drones that could carry a 1,500 kg payload but you say they can’t now in 2019, I’ll bet in 25/1/2019 they have even faster ones that can carry your 1,000 kg bombs easily, and at very low altitude with really good stealth capabilities, and the reason I say that is this, I just seen what they can do, how the f-ck else can you explain the 500 kg bombs landing in Syria without jets to drop them off, did they just throw them across the border. you’re a moron, why do you talk to me, you’re just as right about this as you were about the initial strike on the Pantsir yesterday, your blind and stupid, why say anything at all.
“how the f-ck else can you explain the 500 kg bombs landing in Syria without jets”
I explain that with planes flying at 40/50000 feet over Lebanon/med sea and dropping glide bombs, which has been the standard Israeli tactic since the start of these raids. Such bombs can get ranges up to 80 km in that way, possibly more if lofted.
“you’re a moron”
And you’re the other one, in addition of many other things that are unappropriate to be written here.
Now somebody might think to track down the manufacturer of that circuit board?
it’s an off shelf component you can buy on ebay for 20 dollars.
Israel probably paid 2000$ for it, but doesn’t care as it’s US taxpayer money.
Thanks for the tech chosenites ?. I am sure this will be used to develop both Syrian and Iranian guided bomb technology.
