The US government then decreed that instead of the completed chips being sent directly to China from Taiwan, they instead first go to a US laboratory for testing,

Testing

Is compatible with PAC-3 radar. All in one radar trailer. C band radar like this get a lot of ground clutter noise (less than X band but a lot). Use beam shaping to avoid. Clutter map must be very loose. Weather is snow and cloud for recent day. C band very sensitive to weather. Rain is very bad. Snow less bad. Weaken the clutter map bit more. Sneaky Geran is probably not very visible with this path close to ground. Could even plan route to hide in clutter.

@MarmiteLover123@hexbear.net do Ukraine have any of upgraded AESA type? I think it is pre-AESA.

Correct yes. HF/VHF is much harder to jam from air compare with higher frequency radar. Resolution is low to target but modern computer processing can make detailed enough information to combine. For stealth aircraft shaping and coating can not affect this frequencies at all, it is useless. Stealth is made for X band and Ku band. Longer wavelength will be less affected by stealth. Some breakthrough on other band above the range which stealth protect as well (but very sensitive, easy to jam, not much propagation). Enough data and can get a missile with imaging IR terminal guidance close enough to kill. Infrared sensor have advanced faster than countermeasure against. No countermeasure work any more for imaging sensor with good algorithm.

Jamming pod actually will make plane carrying it very vulnerable. Radar jammer is directional and emit a loud signal to jam. Passive and semi active type missile can «home on jam» follow the jam signal and IR terminal. Anti radiation missile from plane will also kill very easy. Difficult for poor country to counter it but not big power.

Yes this one.

Very interesting page. Choice to not use FMCW is very interesting.

VHF/UHF is completely different properties from HF. Not related.

HF will see stealth and non-stealth the same.

I do not think is a reasonable assumption to make. US was very active in the coast for a long time and attack was very fast and low flying helicopter attack. Very different situation.

Radar probably could see but how to know that it is attack this close?

Definitely JY-27 family is not a primary sensor, is a surveillance radar. Can provide important initial tracking information which will allow other sensor system to find correct sector and vectors.

HF radar is a very different purpose. It is over the horizon strategic radar. The purpose is strategic information. Earliest warning and useful for directing. Can also be satellite-based.

Clear the airspace will also allow Iran to use best attack indicator HF band strategic radar which can track stealth plane with no problem but have low resolution and hard to read in busy airspace.

This will not prevent ground jamming. Jamming is impossible to avoid for parabolic navigation system because it rely on signal from the satellite is stronger than the jam signal and fix the frequency because need specific propagation. Improvement will help with lower power mobile jammer, will make easier to use with own jammer running, but physics do not allow jamming to be stopped. US technology can not defeat physics.

Infrared seeker can provide very good terminal guidance (any modern missile should use in my opinion) but can not get missile to target.

JASSM will limit use of GPS jamming because it is required to use well. INS is very inaccurate for cruise missile and no way to make it accurate. Iran can also jam the GPS. Problem of electronic warfare. Radio is very easy to jam but will effect you too. Hyperbolic navigation always will be limited by jamming.

US will also need large strike to overwhelm air force or to keep Iran on the ground. JASSM cruise at a high altitude to achieve range and can be shot by infrared guided missile with a line of sight.

Will take a very long time.

AGM-158 likely can be shot down by modern infrared missile not too difficult. Iran do not have enough plane and I do not think that air defense system can handle large number and I think it is older generation which AGM-158 is designed to counter. Answer to AGM-158 is modern IR terminal guidance.

Very easy to shoot down with a modern system

Too early to know. World is in transition.

I agree. The cyberattack evidence I found also agree with this. A large cyberattack before the attack. It is a surprise rush.

BGP anomaly for Venezuelan state ISP at time of attack on Venezuela

It is I believe for cyberattack. Reroute the traffic. Snoop and attack.

BGP (Border Gateway Protocol) control how traffic is routed from place to place on the internet. It is old and not secure. US have the most access to infrastructure. BGP is used in other cyberattacks before. I think this attack is very sophisticated.

Several days before attack there is a lot of announce activity on the graph. Huge amount of address space also filled at midnight and released. Unusual route through insecure Italian transit provider «Sparkle» begin a while before attack.

Russia should kidnap him
