AFAIK They won’t put Kh-31 inside Su-57, only Kh-58

A-60 has no radar or rwr and the targeting control LIDAR only cover forward sector, I don’t know the exact range of Lidar but presumably, it is shorter than the distance that APG-81 can track a target as big as A-60.
Tactic: after initial detection, reduce altitude and re-approach from A-60’s beam or tail.

Is it just me or the new Keypublishing forum is 10000000 times slower than the previous one? and constant errors too.

2 external tanks – 4100 km
4 external tanks – 4700 km
range at the super-high speed is 2150 km (Pogosyan – 1500 km)

What TSFC and drag curve did you used for these calculation and where did you get them from?
Can you elaborate your calculation in details?

First and foremost, thank you for spending your valuable time making very details calculator for us.

1.Target RCS conversion tool.
Following my thoughts on the above post, i decided to add the RCS tool into the spreadsheet to facilitate user to predict the upper and lower limit of RCS of his target.

1-This isn’t a big issue but i think it will be easier to use if you let the user input frequency in Ghz instead of Wavelength in meters.
2- I think the estimation of RCS difference might still be too big, at least for VLO aircraft.
Recently re-surfaced video (posted by mig31) indicate that at distance of 30 km, P-18 can’t detect F-117 with 3 out 4 of its frequency setting.

Rough extrapolate from the table
If radar height was 6.35 meters, P-18 will detect targets with RCS= 2.5 m2, cruising at 6km altitude from 132.5 km, reduce RCS by 10 times and we get 44% detection range reduction so F-117 RCS is smaller than 0.025m2 at frequencies >140 Mhz.
If radar height was 10.35 meters, P-18 will detect targets with RCS= 2.5 m2, cruising at 6km altitude from 180 km, reduce RCS by 10 times and we get 44% detection range reduction so F-117 RCS is smaller than 0.0025m2 at frequencies >140 Mhz.

When someone talk about state of the art fighter but don’t know what is a transponder or flightradar24

https://en.m.wikipedia.org/wiki/Transponder_(aeronautics)

I think we were discussing whether F-35 can reach P-40 altitude.

F-35 excess P-40 altitude by a wide margin

Really Uv sensor works well at low height but poorly at medium and high altitudes, because effect of the ozone. So, its good for advice about coming mampads or surface-air missiles, but not against air-air missiles or airplanes. And IR is much better for medium and hight altitudes

UV can’t detect aircraft or coasting missiles and recent BVR missiles with HTPB-AP propellants instead of HTPB-AP-Al will cut down UV detection range by ten-fold, overall, UV sensors have much shorter range and can only detect rocket plumes. With that being said, UV sensors are all weather sensors with lower false alarm rate
