“The aft manoeuvre system” whatever that entails
Yeah, they are being quite cagey. The spinning gyroscope in the animation isn't real.

They look to be using the UMPK kit with increasingly larger/heavier bombs.Russia’s New Supersized Glide Bomb: Our Best Look Yet
FAB-1500 M54s with wing kits are three times larger and are far more destructive than the glide bombs Russia has been using in Ukraine.www.thedrive.com
You can describe UMPK as a "kamikaze glider" - a separate airframe with a suspended bomb. Currently it's ugly, but it seems to evolve into a scaled version of a civilian glider?I suppose thats about the only real advantage that the UMPK has over the JDAM type approach,it doesnt require the fitting of a new tail section with actuated controls,the UMPK simply straps on to the dumb bomb.

Given how bulky&inconvenient Soviet bomb series are - I'd argue that's quite an interesting idea, especially since it allows easily attaching literally anything. And that's a major advantage.
Or they can be used to deliver things like normal naval mines, or even supply crates. It's an interesting multitool.Yes,I could imagine a smaller more compact version of this as an SDB equivalent carrying warheads like the tyulpan 240mm or pion 203mm artillery rounds.
Another possibility would be artillery rockets or RAP variants of large caliber artillery rounds to extend the range of the glide bomb.
So russian SPEAR?Russian TG channel Fighterbomber talks about it:
It's full name UMPB D-30SN
UMPB is an acronym "УМПБ" - "Универсальный Межвидовой Планирующий Боеприпас", which would translate as Joint(?) Universal Gliding Munition . D-30SN indicates diameter, 30cm. By his words can be used on plane or MLRS, hence 30cm diameter. Russian airforce currently uses variant w/o jet engine, but likely to install it later.

Хохлы оценили нашу новинку на поле боя. В этот раз ей стала вундервафля под названием УМПБ Д-30СН что расшифровывается как Универсальный Межвидовой Планирующий Боеприпас (в некоторых источниках Бомба) диаметром 30 см. По сути это планирующая бомба, где вся хурма, а это блоки управления и...t.me
Essentially, it's a Russian SDB, albeit heavier and w/ jet engine.
Heavier and w/o seeker. But yes, close. I'd say it mix of both SDB/GLSDB/SPEAR.So russian SPEAR?
It's quite shorter than Grom:It seems to be full bay-sized, i.e. close to 4m long.
How these bombs are guided ?

Interesting just how simple they are from layout to materials used. One size fits all....They aren't bulky though, they're far more compact than the US MK8* series because they make no allowance for low drag during external carriage. Hence why the bomb in Sineva's post has actually been fitted with a sheet metal nose fairing as part of the kit.
Rather interesting to observe how quickly operational experience is compelling Russia to introduce such kits as a crash programme, after basically turning its nose up at the notion of Western-style gliding PGMs for ages.
It's not like the JDAM is particularly more complicated in assembly. Just that Ed Heineman's Mk80 series low drag bombs were rather brilliantly designed to be easily changed around in terms of fuzing and tail surfaces. Everyone else looked at that and made their guidance packs screw into the same fuze fittings as the nose and tail surfaces.Interesting just how simple they are from layout to materials used. One size fits all....

I'm going to say emergency jettison.Poor quality control, jamming, emergency jettison of bombs?
Bit of a nuisance for anyone who happens to be driving along in a car though. "Not again!"Emergency jettison doesn´t arm the bomb. Given the soft ground nature of the impact location (see photo above) and the crater shape that suggest a vertical trajectory at impact, we can guess this bomb was released during a toss bombing maneuver. Those are highly inaccurate with unguided ordonnance and only depends on the pilot professionalism.
It is of no surprise that some bombs end-up on Russian territory like this.

Not sure if this was posted to this thread or not; do not think I’ve seen it. Boeing has a 7.5 billion dollar contract for JDAM kits extending to Feb 2030. It is not clear how many kits that buys, but even accounting for training, repairs, etc and several hundred million dollars of foreign sales, it is hard to imagine that this isn’t a multi year buy approaching or exceedingly 100,000 units. Previous kits cost between 25,000-75,000 depending on the size of the buy and the sophistication of the kit. Presumably these kits will involve jam resistant receivers which might increase price, though the scale of the buy would tend to push unit cost down.
Any chance powered JDAM is part of this?
Also a six year production run of this size must be building out more than 10k units per year, on average.
Boeing wins $7.5 billion contract from US Air Force for guided bombs
The multi-billion dollar contract for Joint Direct Attack Munitions comes at a time when the military is trying to boost production of multiple weapons.www.defensenews.com
Bear in mind that this is an IDIQ contract, so the quoted contract value is the maximum that can be spent on it, not an actual commitment to spend that much money.
Thanks, I had not noticed that nor am I familiar with the process. Due such contracts have any kind of minimum amount?
An IDIQ (indefinite delivery, indefinite quantity) contract is basically a price list/offer sheet from the vendor that has been approved by the government. Once an IDIQ is in place, the government can order off that list whatever it wants and can fund. There are usually minimum guarantee amounts associated with an IDIQ award, which should be the amount that the government is sure to order. The cap is the outer bounds of what the government might order if all its most optimistic plans are funded.
Is there any way to determine what the likely floor is for the contract cost?
Fiscal 2022, 2023, and 2024 procurement funds; operation and maintenance funds; research, development, test, and evaluation funds; Navy funds; and Foreign Military Sales funds in the amount of $228,196,923, are being obligated at time of award.
