Is an Aselflir-500 really prices more than $1 million?

20000×52= 1.04 million. (Export price)

Is an Aselflir-500 really prices more than $1 million?

1 million $ is a very competitive export price for a system like Aselflir-500. Most countries can't even get an export license from Western countries for a laser designator with a power output similar to that of Aselflir-500. Customers will get a camera with better image performance, a longer-range laser designator, and an HD SWIR sensor which is missing in the MX-15.

An agreement with the amount of TRY 556.743.098,81 and USD 30.262.532,56 is signed between ASELSAN and the Presidency of the Republic of Türkiye Defence Industry Agency regarding development, production and integration of Electronic Warfare Systems for Unmanned Air Vehicles (UAV).
Within the context of this contract, the deliveries will be completed between the years 2025 and 2029.

The ERALP-Early Warning Radar Systems not only detect airborne targets but also those with stealth technology or low radar cross-section targets from long ranges which offers the capability of making hidden aerial threats visible.

What is range?

 

[BalkanTurk90]

According to SavunmaSanayiST 500km+

Aslo depend on size of aircrafts and steathy mode so can be 50km - 1000km for airlines . Averange 400 km for f16 type aircraft .

Ath this point, F35 or SU57 detection renge is of more importance I guess.

It has been discussed before.

ERALP/ERIS or CAFRAD's UMR all will have 450km+ detection range against 1m² RCS target according to @Anmdt.

Which means, it will have detection range of roughly 110km+ against LO 0.005m² RCS targets.

SU57 detection renge

SU57 Not only that thing has worse RCS than a fucking truck with wings, Russia will never have enough of them to cause anyone problems.

ERALP is an S band radar. It has a 450km+ detection range against a 1m² RCS target in S-band and if we do a rough calculation it will have a 110km+ (119.68km) range against a target with a 0.005m² RCS target. What is the RCS of the F-35 in the S-band? This is the 1 million dollar question.

F-35 should still be a stealth aircraft in the S-band but not as stealth as the X band.

Afaik, the lower the band gets the more exposed aircraft becomes as the radar waves gets longer,not the other way around. And X band is higher than S band.

Also, as far as i read F-35's RAM coating is optimised against both S and X band.

Here is a simulation result-

F-35A Radar scattering simulation

Introduction F-35 is the backbone of American stealth fighter fleet, it is intended to replace F-16, F-18C/D, Harrier and A-10. There are currently 3 versions of F-35 which are F-35A, F-35B and F-3…

Yes, that is what I meant. F-35 can't be as good in S-band because of how physics works, but it should still be a stealth aircraft. I wouldn't be surprised if ERALP picks an F-35 at 150km. And there is this thing with maintenance. F-35 needs heavy maintenance to be operated at the advertised stealthiness. Only a few countries will probably be able to keep them in shape.

 

[TheInsider]

My educated guess is that F-35s stealth coating lowers the RCS of F-35 -20 decibels ( multiply the RCS with 0.01m²) at the X band and -10 decibels ( multiply the RCS with 0.1m²) in the S-band which means F-35s RCS in the S-band is roughly 0.01m².

Yes, my guesstimate is also similar. Russian claim about 150km anti stealth range of S400 complex is not technically far fetched. But unlike Russians systems, ERIS/ERALP will be able to do it in practice.

I would have really liked it if Aselsan could have been able to develop something like Ground Fire 300 of new SAMP/T NG that can presumably guide interceptors up to 120km against 0.01m² targets.

Is there any info about SIPER's X band FCR's range?

 

[Quasar]

Sure Having a S band long range detection and surveillance radar is a very very important addition to our capabilities However, S band is common and they are around for quite a while as well, just on their own there is no need to expect a miracle against low RCS aircrafts

Concerning our future, The network created by the combination and managment of our survilance and detection capabilities will be far greater than the simple sum of each single component.

 

[uçuyorum]

More important question is at what range does F35 detect the radar when radar is using that much energy. It is a deterrent but if the F35 can detect and kill your radars from several hundred kilometers that isn't enough for protection on its own. The second matter is electronic warfare, imagine enemy is using F35 alongside multiple powerful EW systems, will radar be able to resist EW while maintaining maximum detection range? But afaik, you do start needing much thicker coating to resist lower frequencies and from quoting thisanalysis [https://www.veryansintv.com/yazar/beyazit-karatas/kose-yazisi/turk-kartali-milli-muharip-ucak-1/] particularly at L band F35 is most detectable although L band will make it difficult to differentiate targets.

It has been said, Spectra's passive detection range is more twice that of APG-81's active detection range.

The second matter is electronic warfare, imagine enemy is using F35 alongside multiple powerful EW systems, will radar be able to resist EW while maintaining maximum detection range?

Obviously not. In that case radar has to burn through to see. Which will inevitably decrease its effective detection range.
