2/7 For the longest time, we'd wondered what these circular caps on bottom of the missile were for. Now we know: they're covers for penetration aid tubes. During the terminal part of its flight, the Iskander-M can poop out up to six penetration aids. But what are they? pic.twitter.com/ZWK0czZYlS

3/7 Generally speaking, penetration aids (PENAIDs) can work three different ways: physically, as a decoy, using its radar return; thermally, using a flare to spoof heat-seeking weapons, and electronically, spoofing or jamming radars and electronics.

4/7 The Iskander-M PENAID does all three. The body's radar return adds clutter around the missile. The end of the PENAID has a flare to create a strong thermal signature. The interior of the PENAID has a radio transmitter to jam or spoof radars. pic.twitter.com/cWworxVKJH

@DuitsyWasHere @Ascii211 shows that there is a shiny metal can that is of narrower diameter than the rest of the device, which only seems to sit back toward the 'nozzle' section. As others have suggested, it could perhaps be a thermal battery. This section of the rocket is often discoloured such that 15/ pic.twitter.com/D9IOJlewuk

@DuitsyWasHere @Ascii211 The company that claims to have designed & manufactured the unit (Product 9B899, "System-200") had a museum (they've since built a new museum to replace it) that they took some panoramic pictures of for a "VR tour." A copy is sitting in a corner. signalrp.ru/company/museum… 6/ pic.twitter.com/WntbjU0TPA

おそらく9B899囮弾は最後部が熱源体として機能する。そして弾体の大部分は電子ジャマー。あとこの丸い部品、TO-3のパッケージだよね・・・ pic.twitter.com/PVK3dfH0bO
