I find it somewhat hard to find information on how common APS systems actualy are and what the cost of them is.
There is a lot of information of varying quality about the systems and their aledged capabilities themselfs around but I have so far not seen any in action.
We saw those cylindrical "things" on syrian tanks but I think consens was found that those are propably rather jamming devices or other EW Equipment then actual APS.
Can anyone maybe share some light on the topic? I would have thought the current conflict with its wide variety of different atgms and at missles would be a perfect testing ground for APS.
There are several types and subtypes of APS to talk about:
Hard-kill:
Trophy, Iron Fist, high energy lasers (air defense assets), Arena, Afghanit.
Fortunately and Ukraine, and unfortunately for Russia, they were not used in Ukraine, and Russia doesn't even have any operational AFVs with any form of hard-kill APS to begin with. It is unlikely to get any because there are no indication any domestic system has finished development, and because tanks' capabilities are not the bottleneck there.
Russian APS ironically often neglect the threat of top attack munitions that are so prevalent in the west. The western APS ironically add top attack protection despite no top attack munitions in Russia.
Hard-kill APS were proven in Gaza though, when Trophy systems intercepted ~15 ATGMs and ATRs.
Soft-kill:
Jammers/dazzlers:
Russia has T-90A tanks in stock which have the Shtora. But jammers and dazzlers are usually very threat-specific. The Shtora APS is specific to one variant of the TOW, and will be useless vs anything else.
Smoke grenades:
Could be manually or automatically activated. Can be simple smoke or some multi-spectral effectors. Smoke is generated by a fast burning agent, so it may create a heat spot that may confuse heat seeking missiles like the Javelin. The NLAW will not be affected for example after launch.
Russia has smoke grenades on its tanks, manually activated. However, their efficiency is limited and they must be used wisely to generate some effect.
Since we see many destroyed tanks that may have been ambushed, smoke grenades likely have little to no effect on their survivability.
