From AW&ST

F/A-18 E/F Super Hornet Block III to get an internal IRST instead of current solution which is mounted on the belly drop tank


Next Phase Of IRST Upgrade For F/A-18E/F Begins
Aerospace Daily & Defense Report Nov 26, 2018 , p. 2
Steve Trimble

Lockheed Martin has begun the second phase of a project to integrate an infrared search and track (IRST) sensor internally on the U.S. Navy’s BoeingF/A-18E/F fleet.

Boeing awarded a $108 million contract to Lockheed to complete the development, testing and qualification of the IRST 21 Block II sensor.

The award comes a year after Lockheed received two contracts from Boeing worth up to $100 million to launch Phase 1 of the IRST 21 upgrade for the F/A-18E/F.

The Navy also awarded Boeing a $152 million contract in August to start working on the second phase of the IRST 21 Block II development program.

The second-generation IRST 21 is one of several upgrades that form the configuration for the Block III version of the F/A-18/E/F.

“The IRST 21 sensor system provides U.S. Navy F/A-18E/F operators with superior detection and survivability capabilities,” said Michael Williamson, vice president of Sensors and Global Sustainment for Lockheed’s Missiles and Fire Control business.

The two-seat Boeing-made fighter is expected to operate alongside the Lockheed Martin F-35C until 2040, when it will be replaced by the planned Next Generation Air Dominance fighter.

To keep the F/A-18E/F relevant over the next two decades, the Navy is adding several features to improve its performance in long-range air-to-air combat.

In addition to the IRST 21 Block II, the F/A-18E/F Block III will also carry a new advanced cockpit display to improve situational awareness and a Tactical Targeting Network Technology (TTNT) data link to enable sensor fusion among multiple aircraft. An IRST sensor can detect targets at long range by their heat signature, rather than risk exposing their position by using a radar.


The Navy launched the original IRST 21 upgrade for the F/A-18E/F fleet in 2011, but it entered operational service on the Block II version of the aircraft in the nose of a belly-mounted fuel tank.

The F/A-18E/F Block III is redesigning the aircraft to incorporate the IRST 21 Block II internally.

The drop tank IRST sensor was always meant as an upgrade to the existing fleet with fewer pods acquired than the number of aircraft in the fleet allowing the sensors to be rotated. With now a larger block-III order, and likely a revival of the EA-18G upgraded to Block III there is now a decent number out there to deploy the sensor internally.

And... Khan already knows about the GaN SAAB will likely put in the Indian fighter.
https://www.ainonline.com/aviation-news ... -gan-radar

Meanwhile, Saab has been contracted by the U.S. government to supply an X-band AESA fighter radar for evaluation as part of the Foreign Comparative Test (FCT) program. The radar incorporates GaN (gallium nitride) semiconductor technology in its transmit/receive modules. Compared with the GaAs (gallium arsenide) semiconductor used in most current “e-scan” radar arrays, GaN permits more power to be transmitted through the array while generating less heat.

Saab’s GaN fighter radar draws on experience with the mechanically scanned PS-05/A radar that is in service in the Gripen C/D and has been offered as a potential system to India for the HAL Tejas Mk 1A fighter. The next-generation Gripen E/F features Leonardo’s ES-05 Raven repositionable-array radar that uses GaAs technology.

^ That antenna that SAAB is supplying the US Navy is meant to gather data using airborne testing for a future surface radar program (not a fighter radar) for which they sought an off the shelf airworthy X-band GaN antenna with an architecture that could be mated to their desired capability for rapid testing so I am not sure that SAAB will have USN funded flight tests of its full up radar saving them the effort and investment of doing it themselves (which they have so far resisted).

There is a Mid-2020s requirement for an AN/SPQ-9B replacement which this S&T program is likely supporting. Beyond this there has not even been an RFI issued for any other X-band radar from the USN for any other (surface or airborne) application. The only other application that I can forsee the USN requiring is a new sensor competition to replace the GaA (X-band) AAS on the P-8's but for that mission both Raytheon and Northrop already have a flying X-band (Northrop dual band X/Ku) GaN radars so it doesn't look likely that they need data to support that program.

Jane's IDR wrote:While Saab is supplying an airworthy system for the purposes of the X-band Active Aperture Array system FCT, the J&A suggested that the ONR’s interest is primarily in a future surface radar programme.

All I am saying is that unless we field Uttam en masse or a derivative, any "special" technology we possess will invariably be in the hands of some other country with the corresponding issues.

Well Leonardo is a finmeccanica subsidiary... I would dearly love to know how that would fly (pun!) here.

and GaN roadmap of theirs is pretty well known. The Raven GaN replacement is still a ways out.

The ES-05 Raven is the radar that is on the Gripen-E. SAAB's GaN radar demonstrator is something they have developed with their own radar division and is not a Leonardo product meant as a Raven upgrade. I don't think Leo has revealed a GaN roadmap for the ES-05 family. I assume their first and foremost priority would be to get the radar into service and being able to produce at a high enough rate to enjoy EOS.

So far neither of SAAB's customers has shown a willingness to flight test SAABs radar or look to replace the ES-05 on the Gripen-E even before the aircraft enters service. SAAB's strategy is to offer their radar for international fighter programs. They started their campaign in South Korea and have offered the radar to India as well iirc.

Oh i meant the roadmap for their GaN development, not the Raven radar or is possible replacement.

With the Rafale battle still going on, any " contest" for aircraft for the IAF will come a cropper. Only G-to-G deals will sail through.The IAF thetefore should have a definite plan B to augment numbers, while intense LCA prod. increase efforts are going on just for MIG replacements.
Plus, as time goes by, and the Chins unveil and introduce newer more capable birds, the demand is going to bd fof more modern aircraft rather that ' 70s vintage birds in their last avatar.Plan B alternatives must be prepared asap by the IAF so that a quick decision can be taken by the Cabinet before the ' 19 hustings.
