Is it known what the first of the rolling updates for Block 4 will be? Has it already happened back in April or is it due to happen in October?

Block 4 comprises some 53 improvements to counter both air- and ground-based threats emerging from China and Russia. None of these upgrades will change the aircraft’s outer appearance, or “mold line.” Instead, they are primarily new or enhanced features executed in software, which will be rolled out in stages, with updates every April and October starting in 2019 and continuing through at least 2024.

Raytheon is showing an F-35 model at #AWS20 with a centerline store I’ve never seen before and can’t really guess what it is. Still trying to figure out what it is. Doesn’t appear to be a munition. Maybe a semi-conformal fuel tank or new sensor.

My first thought was a laser pod :D

The model is too inaccurate to make any sense. The shape of fuselage, wing and horizontal tail is quite wrong.

I'll play: HVPW

To let the Lightning hit with a GBU-28 equivalent penetrating weapon.

It's just an old concept for the gun pod.

Future F-35 Panoramic Cockpit Display System to Feature Better Processing, Memory
24 Apr 2020 Frank Wolfe

"A new Panoramic Cockpit Display – Electronics Unit (PCD-EU) for the Lockheed Martin F-35 is to feature significantly enhanced processing and memory. The PCD-EU "is considered a new development effort under the F-35 Technology Refresh 3 (TR3) effort and will provide improved processing capability and video formatting," Lt. Cmdr. Keith Goodsell, a representative for the F-35 Joint Program Office, wrote in an Apr. 24 email to Avionics International.

"The system is comprised of independently controlled display management computers for each half of the Panoramic Cockpit Display – Display Unit (PCD-DU), allowing for greater situational awareness as well as redundancy for flight critical displays," he wrote. "The PCD-EU also incorporates both safety and non-safety critical processors, allowing for approximately four times the processing capacity and 32 times increased memory capacity. Finally, the PCD-EU will enable Hardware Open Systems Technology (HOST) to address power distribution, signal traffic dynamics, module diagnostics, signaling protocols and module commonality."...

...Nearly $82 million was awarded to procure hardware and software elements for the forthcoming Block 4 capability upgrade. The Block 4 upgrades, to take place over this next decade, will include new information technology capabilities, particularly the TR3 package with an updated integrated core processor (ICP) by L3Harris and the PCD-EU. An open-architecture backbone is also expected to be integrated into the F-35 as part of the Block 4 capabilities.... [lots of stuff I don't understand then...]

...L3Harris has been developing the new, F-35 ICP, which, like the PCD-EU, is to go aboard F-35s starting with Lot 15 in 2023. Lockheed Martin built the legacy ICP at a facility in Eagan, Minn. which closed in 2012. Avionics work done there has moved to the company's Rotary and Mission Systems (RMS) division in Owego, N.Y.

The new, L3Harris ICP "is based on advanced open systems architecture and COTS technology, which pave the way for system upgrades to the F-35 well into the future," Bryant Henson, president of L3Harris Space and Airborne Systems' mission avionics sector, wrote in a recent email to Avionics. "Much of the F-35’s sensor and ISR capabilities will be made possible by the ICP. The new processor will increase by 25-times the collection of data from the aircraft’s sophisticated sensor suite to identify enemy radar and EW [electronic warfare] emissions that will provide the pilot with 360-degree situational awareness of threats and then prioritize and recommend to the pilot how to counter or negate the threat."..."

Thank you for that info, spazs! Now that is pretty impressive performance increase especially given how pilots have described the current performance levels with all kinds of superlatives. It seems that currently the performance bottleneck is the ICP and not the sensors themselves.
