Russian T-55's have reached the frontline.
The War in the Ukraine
- Thread starter SampanViking
- Start date
Not even upgraded beside the cage. It still make a nice mobile pillbox.
How did he know Russians using exclusively Optical targeting... these missiles do spawn on Radar albeit at of course reduced range compared to something bigger. Optics are for jamming or when shooting something really close. Optics are also bad at searching volume. The early warning has to come from somewhere else.
HARM is well not really stealthy. It does have small RCS but it can be engaged just fine with radar like Buk or Pantsyrs. This is example of RCS prediction i did for both AGM-88 and the newer AARGM
Ukrainians have AGM-88, this have Median frontal RCS of 0.4 sqm in VHF band, while for X-band it is 0.04 Sqm while for Pantsyr's engagement radar it's 0.1 sqm (34 GHz) and 0.07 sqm for S-band.
To put into context.. let's assume something like Niobium-SV radar. I made prediction on range of this radar based on similarities to Nebo SVU. Assuming a VHF cross section of 2.5 sqm a value typical for MiG-21. Nebo SVU can detect the target at 270 km. The same target would be detected by Niobium SV at 199 km or let's round it to 200 km.
Now i assume it's 50% PD with SNR value of 11 dB. For a steady track 90% or stronger signal is required let's assume 17 dB. The HARM would be detected reliably at 90 Km.
While something like 92N6 assuming it receive designation from command post.. it can do about 80 km, locking on and engage. Cued search however can actually achieve longer range as the radar can optimize the dwell time. It only needs to search smaller area.
For Pantsyr it would be able to detect inbound Harm at 12-26 km if one follows the Russian materials. While engagement is at 10 Km.
and to say nothing with engaging HIMARS rocket, it cannot really be done optically as it will quickly overwhelm the operator as he will contend with multiple targets.

The cope cage is funny. I wonder if the crew of that tank know that Javelins have direct attack mode?
Most threats are not being fired, but appear to be affected by electronic warfare measures.
Because HIMARS is faster, it is more difficult to affect it with these systems, as it jumps from area to area of action of the EW system and does not have time to create cumulative error, even so this seems to have been solved with relative success according to what little we know.
However, during the first few months the GMLRS wreaked havoc, while the JDAM-ER seems to have failed from the start, being slower it is easier to affect it with EW.
In a similar vein, the GROM missiles and the Tu-141 drones.
Although the Tu-141s were recently converted to missiles, due to their novelty the EW did not work the first time, but now they are crashing in odd places, as are the GROM missiles, which suggests successful interference with their positioning system, the GROM is faster than the 141, but has not yet succeeded in any of its attacks.
We will see how it affects the missile, but I think the main defence is:
1 - Protect key elements and disperse targets. For example, put planes in bunkers and don't leave them out on the runway and together.
2 - EW measures
Firing them is a last resort solution.
It is more funny some keep trying to push this is against Javelins and not against drones dropping grenades
This is account is claiming that T-55/54 are being used as makeshift artillery with 3-men crews

The current status of the Kerch bridge is unconfirmed for the rail side, I think currently only one rail is operational while the other is still undergoing repairs so a missile strike to disable the rail connection is not out of the question.
All rail went back to normal around 1 week ago.
