While Ms Poblete did not specify which Russian satellite she was talking about, military analysts believe it was one of a set launched on June 23. A month later, the Russian Ministry of Defence announced it had launched “a small-sized spacecraft has separated from a space platform in order to inspect condition of the Russian satellite.”

Kosmos 2521 was believed deployed from another satellite, Kosmos 2519. Close by is another satellite, Kosmos 2523.

A good reminder of the level of work that was put in by France before sharing programmes with other nations.
They are publicly demonstrating that you had better have a direct hit on the warhead or that nuke is still going to go off.

It seems that the blast tore the RV apart. Note that just as the blast hits the region of the RV gets censor-blurred, and when it clears up again the RV ain't there. If the RV had been simply blown away, it'd be no biggie, but if it got splayed open and the innards were briefly on display, they might want to hide that.

Sure, but how much time did it take to tear it apart vs a self-destruct mechanism setting off a hypothetical nuke?  One of the Mk21s settings is to go off on impact.  Wouldn't an RV at impact would be going faster than that blast wave in the video?  ???

Tupolev has rolled out the first upgraded Tu-22M3M ‘Backfire’ at the Kazan Aviation Plant in Russia
Notice, that the refuelling probe is back.

Thanks a lot flateric, overall for the link concerning the Petit Duc AVE program :)

But it seems that there are mistakes in some links (Wikipedia) and in older posts of this topic.

AFAIK (from Air & Cosmos French weekly magazine) :

-AVE D (first flight July 2000) and AVE C (first flight June 2003) were parts of Petit Duc Program. The weight of each model was around 60 kgs.

-The Moyen Duc (first flight ca September 2004) program was based on the AVE C's shape, but it was not the AVE C and its weight was around 500 kgs. For the same reason, the 2004 tactical UAV Dassault-Sagem SlowFast was not "based on the Moyen Duc AVE C", it "was the Moyen Duc" and "based on the Petit Duc AVE C".

Considering tu22m3 combat radius is usually quoted at 2200 or 2400 km, it's highly Likely tu22m3 even with a single kinzhal can't do 3000 km of combat radius. Unless it gets its ifr probe retrofotted.

What payload ?.


I tried doing my own estimate using data from missilethreat. and Fleeman's tactical missile design book

Found that Kinzhal itself is about 1000 Km range. with apogee of 254 km and terminal velocity of 2.8 km/s.

The assumption is as follows  :

Launch Weight : 4300 Kg
Warhead : 480 Kg
Structure: 22% * 4300 Kg = 946 Kg.
Guidance, Battery and Actuators = diasumsikan 300 Kg.
Propelant load = 72% dari rocket motor weight, 2574*72%=1853 Kg.
ISP  : 265 S

Launch condition :
Altitude : 15000 m
Starting Velocity : M 0.85
Motor burn : 15 detik.

During trajectory, it's assumed that the missile will have 2 minutes coast to apogee.

Depending on AI/computers over able bodied individuals is dangerous slippery slope. Computers, much like myself are seldom correct and always sure ;D
