L band has poor resolution and does not provide altitude information. It is akin to saying you may have found someone in a deserted 100 story building but you don't know which floor the person is occupying. Sending an active seeker missile in an attempt to target that person in the building is not a narrow search box.
Detection ranges can be reasonably approximated based on radar equation as one would assume Aviation week has done as they are a reputable magazine. The calculations are not rocket science once you base it off certain information given on the product by the manufacturer. There are variables that can affect detection ranges that can be assumed and as long as they are applied consistently across it will ensure objectivity. There are other variables such as RAM properties that are specific to each aircraft and so they are not factored in.There are a number of variables that can influence detection ranges and one should be aware when comparing against different sources such as; (I)receding vs head on; (ii)look up vs look down; (iii) clutter ; (iv) probability of detection assumed et al.
For example, I can determine independently an approximated detection range of IRBIS-E based on the information provided by the Russian manufacturer. We know publicly IRBIS-E can detect a 3m2 target at 400 km using narrow search. A rule of thumb is to half the detection distance to get to normal search i.e. 200 km. A 1m2 target is approximated to 170 km. With that base number 0.1m2 RCS = 102 km
0.01m2 RCS = 62 km
0.001m2 RCS = 37 km
Now these detection ranges are based on 50% probability of detection. A 90 % probability will further reduce the detection range.
I have explained above with the 100 storey building.
Additionally, doubling the detection range requires 16 times the transmitter power. Effectively you would be lighting up your radar like a Christmas tree.
The argument with VLO is that the F-35 can get very close to a target without being detected. EW is therefore unnecessary.
Detection is simply a S/N relationship i.e. a signal is picked up from the noise.
Jamming is a J/S relationship i.e. jamming is simply noise creation so that the signal is not picked up or detected as we normally refer to.
Not everyone has F-35s. In any case F-35s were designed to take on systems like S-300/400.

yeah "some source said" according to
in a whiskey bar?
The F-35A, America’s most advanced multi-role fighters actively opposed combinations of the most advanced weapons systems out there, meant to replicate near-peer enemies in a large scale conflict during exercise Red Flag 19-1 at Nelllis Air Force Base.
According to a statement released by the U.S. Air Force statement, the 4th Fighter Squadron integrated the F-35A into a large, capable “Blue Force” in diverse missions against an equally capable “Red Force.” Nearly 3,000 personnel from 39 separate units participated in the exercise, including the U.S. Navy, U.S. Air Force, Royal Air Force and Royal Australian Air Force.
During exercises, the F-35A multi-role fighters, which brings game-changing stealth, lethality and interoperability to the modern battlefield have faced Red Force’s hybrid threats, combinations of the most advanced weapons systems out there, meant to replicate near-peer enemies in a large scale conflict. The shift closely aligns with the National Defense Strategy.
Red Flag aggressors encompass the whole spectrum of an adversary force – advanced integrated air-defense systems, an adversary air force, cyber-warfare and information operations. Because of these diverse capabilities, many Red Flag missions are flown in “contested or denied” environments with active electronic attack, communications jamming, and GPS denial.
“Those situations highlight the fifth-generation capabilities of the F-35. We’re still able to operate and be successful. In a lot of cases we have a large role as an integrated quarterback,” said Lt. Col. Yosef Morris, 4th FS commander. “Our ability to continue to fuse and pass information to the entire package makes every aircraft more survivable.”
During the first week of Red Flag, the F-35 pilots flew in a larger force of Blue Air in a counter-air mission. More than 60 aggressor aircraft were flying against them, blinding many of the fourth-generation aircraft with “robust” electronic attack capabilities.
“I’ve never seen anything like it before,” Wood said. “This is not a mission you want a young pilot flying in. My wingman was a brand new F-35A pilot, seven or eight flights out of training. He gets on the radio and tells an experienced, 3,000-hour pilot in a very capable fourth-generation aircraft. ‘Hey bud, you need to turn around. You’re about to die. There’s a threat off your nose.’”
The young pilot then “killed” the enemy aircraft and had three more kills in the hour-long mission.
“Even in this extremely challenging environment, the F-35 didn’t have many difficulties doing its job,” Wood said. ‘That’s a testament to the pilot’s training and the capabilities of the jet.”
One of the most valuable things about this exercise for the 4th FS is the experience it provided younger pilots flying combat missions as part of an integrated force. Thirteen pilots in the squadron have never flown the F-35 in Red Flag, and four of them just graduated pilot training.
“They say it’s the most realistic thing to combat,” said 1st Lt. Landon Moores, a new F-35A pilot. “It’s been pretty intense.”
Red Flag is not a rolling campaign. It is made up of different scenarios that increase in difficulty as the weeks go on. This allows the integrated force to learn how best to capitalize on the strengths and protect the weaknesses of each platform in very specific mission sets.
“With stealth, the F-35 can get closer to threats than many other aircraft can. Combined with the performance of the fused sensors on the F-35, we can significantly contribute to the majority of the missions,” Morris said.
The missions aren’t just 90-minute flights. They require 12-hours of intense planning the day prior, a two hour pre-brief, and then several hours of debriefing after the mission – dissecting the outcome and looking for ways to improve.
“It’s not like we just come back and high-five if we’re successful,” Morris said. “Could we have done better? Did we have all the resources we needed? Often the brief and debrief is the most valuable part of Red Flag, especially for younger pilots.”
The squadron brought 12 aircraft and more than 200 Airmen to the three-week exercise – pilots, maintainers, intelligence officers, weapons crews, and support personnel, including reservists from the 419th Fighter Wing. Maintainers didn’t lose a single sortie to a maintenance ground-abort and had spare aircraft available for every mission.
“As this aircraft matures, we continue to see it be a significant force-multiplier in a threat-dense environment,” Morris said. “Red Flag was a success for us and has made our younger pilots more lethal and more confident.”

Lawmakers stand ready to protect F-35 from F-15X budget threats
:
"On Feb. 13, Republican Sens. John Cornyn and Ted Cruz of Texas, Susan Collins of Maine, Marco Rubio of Florida, and Lisa Murkowski of Alaska sent a letter to President Donald Trump asking him to rethink the F-15X buy. All five senators come from states that make the F-35 or where the Joint Strike Fighter is planned to be based."
just a coincidence LOL

NO!, its not a coincidence, and that's what representatives are supposed to do, represent their constituency.... in this case, that's smart, although I'm not necessarily opposed to the F-15X,,, its a fine airplane... but it wouldn't last long without a 5Gen escort in contested airspace, maybe only a little longer with a 5Gen escort...
4Gen, and 4++Gen alike are in lot of trouble in airspace where S400s etc populate, you really should understand this by now???

thanks for reading my posts LOL
you know I don't believe much in your F-35 hype
could be kinda modern F-16 "eventually", but A-10 replacement common ... the USN part Feb 11, 2019
