I think it is wrong to say Çafrad is the heart of TF-2000 anymore. Design changed considerably and that tweet line is outdated. ÇFR is now tasked with surface detection, EW and IFF, not anti air warfare, which is the main task of the TF-2000.

It is, it's from when it was tested aboard a Gabya Class frigate back in 2018.I feel like that is an old photo.

First of all Murat is GaN based radar,APG 83 is GaAs so Murad radar is more tolerable to heat from APG83 this make more power for transmission of RF for the same cooling capability.I thing on the reciever side signal to noise ratio is also better than GaAs system,this is more important than the power of RF signal transmission.Contrary to public belief about APG 83 is also use liquid cooling system,but with help of air cooling system of F16.Air cooling limit of F 16 is 9 kVa and there are many systems need cooling.APG 83 is limited in terms of TR power by software to protect radar.We do not know anything about this on Murat nose radar.Cooling capacity only 4.5kw feels low. It is similar to APG-83's (estimated) air cooling on F16 B70. Wouldn't that put limitations on MURAD's duty cycle? @TheInsider @Anmdt

I think aircooling is also in charge,so do not worry.As you know on aesa tech some pinpoint heat can be extreme high,thats were liquid cooling is more beneficial than air cooling.The main electric power of F-16 is 60kVa,so you cannot make a full support of aesa radars GaAs or GaAn,so you have the limits of supply power and cooling.APG 80 matter is very different,they changed a lot of things,turbofan motor,power suuply,cooling,even nose is changed,so its superior to F-16 V and also to F-16 özgür with murat aesa radar.I do know that. But there is more to this than simple GaN/GaAs equation. Other than antenna array, receiver exciter processor and other subsystems also produce heat. For APG-83 it is assumed to 1.5kw. if MURAD's subsystems is in similar range, then for antenna array you are left with 3/3.5 kw of cooling capacity. That's seems low even for GaN array. (If it were to operate to its fullest ability)
Are these for Türkiye or are these for export costumers who now don't have to order them themselves when they order UAVs from Türkiye.EO is hard, building them in numbers for the cheap is harder.
Looks like Turkey bought 25 million worth of "Optical devices, appliances and instruments" from Canada in June 2024 alone. Surely there are some smaller articles in the total number for medical and recreational use, but suffice to say lion's share would go to Wescam.
Even with embargo in place, customers would order the EOs from Wescam and have it attached by Baykar technicians in the host country. So I doubt that.Are these for Türkiye or are these for export costumers who now don't have to order them themselves when they order UAVs from Türkiye.
Pretty sure we already saw some exported Akincis or Ankas in the past since the ban was lifted with Wescam EOs.
Easier to sell the whole package to your customer then having them order separate EOs.
Yes, this looks underwhelming.Cooling capacity only 4.5kw feels low. It is similar to APG-83's (estimated) air cooling on F16 B70. Wouldn't that put limitations on MURAD's duty cycle? @TheInsider @Anmdt
Aselsan can produce 8 maybe 10 (96-120 per year) Aselflir 500 per month. This amount of production can hardly satisfy our needs if we take exports into account.EO is hard, building them in numbers for the cheap is harder.

It seems, we have power shortage for using all capacity Murad radar. Actually we talked for Akinci before at forum and we talked about external power supplies. This kind of solution in a short time and as a cost effective can be applied as generic solution.Yes, this looks underwhelming.
On the producer's website, it says under the defined conditions it has a 4.5 kW cooling capacity please contact us for cooling capacity. Murad radar has various implementations for Kızılelma, Akıncı, F-16. I don't know if this cooling system is common across different versions.
Defined conditions are 10 LPM(liters per minute) 60 degree Celsius @3.5 bar.
This is the specs of the pump of the system
35 LPM @ 3 bar
So it looks like the cooling capacity can be increased.
When you are cooling the radar you are limited by the cooling system and how much air passes through the radiator of the cooling system (ECS/RAM air). As far as I know, the ECS of the F-16 provides enough air to cool 12 kW. Unless you modify the ECS and add more airflow you are limited by this budget. Needs like Cooling avionics and air conditioning cockpit spend some of this budget and 9kW is left to cool the radar. APG-83 SABR has a 5.5 kW cooling system APG-68(v)9 has a 5.6 kW cooling system. APG-83 is designed to replace APG-68 without modifying anything. It brings better performance than APG-68 because of better efficiency(more bang for the same buck). The same logic applies to Murad radar but I thought TAI/Aselsan would do ECS modifications to increase the airflow for more cooling capacity to bring even more performance. It seems like that might not be the case. We will wait and see. Anyway, 4.5 kW is an odd figure. If you change nothing you should exactly do what SABR developers did and use a 5.5kW cooling system and call it a day.

Here is an article from 2022 about CATS production

ASELSAN CATS Teslimatları ve Üretim Kapasitesi Artıyor
ASELSAN Yönetim Kurulu Başkanı ve Genel Müdürü Haluk Görgün, CATS Elektro-Optik (EO) Sistemi hakkında güncel bilgileri paylaştı.www.savunmasanayist.com
As of this date, over 40 cameras have been delivered to the user. Our mass production continues. We have reached the level of producing 6 per month, and we are trying to increase this to 10.
Finally, the Turkish Armed Forces stopped ordering Wescam products after the Aselflir-500 there is an order in effect about that. Wescam products are related to export deals.
