It's the exact same image as in the previous page. The advanced IRST requirement was dropped during Dem/Val, and on the F-22 the system would initially have been dual sensors at the wing roots, which was later moved a single one under the nose. A requirement in EMD was later added to retain that space and cooling for future addition. Evidently that space is no longer available, perhaps repurposed for something else, hence these specially shaped pods.So what is this optical equipment for on the F-22? An IRST that should have been included on the ATF program from day one?
While any possibility of buying the Lockheed Martin F-22 Raptor has repeatedly been dismissed by politicians over the past decade or more as being too expensive, too inflexible and “not for sale”, following an informal RFI there was a proposal put to the Australian government by the US early in the AIR 6000 process for an export-configured Raptor which would have satisfied US ITARS arms export control laws while still providing a high-end capability.But the proposal was never seriously considered for a number of reasons, including the fact the aircraft was designed primarily for the air supremacy mission with only a secondary strike role and had no maritime strike capability. In addition, apart from the high unit cost, there would have also been a huge additional investment required as lead customer for the development of the export version.

Seems it will use 2 IRST pods, is this for triangulation, or are these different pods?
If the pods do also have an EW function as suggested previouslyIt seems unlikely triangulation would be possible over such a short distance with that little distance between the sensors. Perhaps there was some kind of funky phase or time of arrival analysis you could derive range. I cannot fathom what the mechanism would be but it might be possible. If nothing else superior field of view as noted above.
then FOV will also be important especially as a pod that size is likely for high bands.The pods also carries some EW equipment, so despite some tradeoffs it's an overall increase in capability and survivability.
Weren't there photos of modded testbeds sporting IRST systems way back when? To clarify, they had them inbuilt in the roots, noses, and other areas of the testbeds.
current system is being developed by Raytheon
Maintenance and logistics. Use the same stuff as F-35 and/or B-21 (assuming that Lightning and Raider use the same RAM).Why would you want to apply a new RAM coating? What problem would it solve?
You can get naval-gunfire-quality triangulation over 50km with a 10m spacing.It seems unlikely triangulation would be possible over such a short distance with that little distance between the sensors.

Recent Raytheon contract award broadly aligns with the amount for Group B procurement funding under the Sensor Enhancement line item for the F-22. The contract language even spells out Group B hardware.Why do you say the podded IRST is being developed by Raytheon?

With the future of America’s next air superiority fighter now in question, America’s king of the skies, the F-22 Raptor, is set to extend its reign well into the 2030s, thanks to a slew of upgrades already underway — and the list keeps getting longer, with some $10.9 billion allocated to improving the Raptor fleet by 2031.
But with only 150 F-22s in combat service... Can improving this endangered species of a fighter really be enough to maintain America's air superiority edge?
Alex Hollings from Sandbox has just uploaded this video concerning USAF plans for the F-22:
If from the get go they had common components with the F-35 it would be a lot easier to modify/maintain the existing fleet.
It wouldn't have been worthwhile unless the we got the full 381 aircraft that the Air Force wanted
What does the cost of a flight hour consist of?
The F-22 has a full life of 8000 hours, the cost of the machine for the US Air Force is 168 million. $
thus, an hour of resource costs 168 million $ : 8000 h = 21000 $
fuel cost in the USA in April 7.5 $ / gallon or 1.98 $/ kg
fuel consumption 3600 kg / h 3600 kg * 1.98 $/kg ~ 7000 $/h
$21,000 (resource) + $7000 (fuel) = $28,000$
68,362 left - $ 28,000 = $ 40,362
What can be included here? pilot's salary, technicians' salary, maintenance...
There's a number of maintenance-hours that have to happen after every flight, and that's divided up across however many specialties and trades are needed.What does the cost of a flight hour consist of?
