Some reading on Tile & Brick (aka Slat) AESA modules.
http://www.rfwireless-world.com/Terminology/Slat-Array-Antenna-vs-Tile-Array-Antenna.html
Basically, Tile is smaller & cheaper but Brick arrays are easier to cool thereby allowing greater power levels.
The purpose of 3i was to certify the 2B build on the new hardware included with Tech refresh 2. The USAF also demanded a few extra tweaks before they used it to declare IOC.
The parts of the software that had to change were the “middleware” components that host the VMs.
All weapons & performance metrics are the same for 2B and 3i.
They stopped building 2B jets years ago. Lots 2-5 (through FY2011 jets) need the 2B upgrade and everything after that is 3i until the 3F started rolling off the line this year. Some of the Lot 2-5 jets are getting upgraded to 3i/3F which is why the actual number of jets that may be staying at 2B for a while is a little fluid. Remember that this is not a plan set in stone, only one of many proposals.
Ejection seat issue not so fixed???
It’s fixed. The issue is that an internal Testing department in the DoD wants more testing done on it than has ever been done on any previous seat.
quite expensive for a trainer…
They are talking about F-35 training units that already fly the aforementioned Block 2B jets.
Take a look at the map.
Most of those at Luke AFB, Eglin AFB, and MCAS Beaufort are training F-35s that will never need to see combat.

Around 100 F-35 would not be upgraded to level 3 std vu reamain with 2B software…
That is 1 of several proposals and nothing has been decided.
Once again, You start krap with a country and they kick your a$$..
I don’t have time to reference anything but Wiki, but I assume that “1956” refers to :
https://en.wikipedia.org/wiki/Reprisal_operations
and 1967 is the Six day way.
And?
You start krap with a country and they kick your a$$.. Then you think you get your land back?
@Bayer that covers wartime occupation, not land that is captured and still in the hands of Israel after the war is ended (ie ceasefire/treaty).
I can’t recall any of the Arab states surrounding Israel ever paying Israel for any of the wars inflicted on it so that convention is pretty toothless.
gaining territorial enlargement trough war was forever banned?
By who, the UN? They are a joke and hold no legal authority over Israel.
If you are talking about a “War Of Aggression”, that does not apply since Israel was the nation that was consistently attacked and not the aggressor.
um, Yes it does. War has consequences and if you lose a war, you can lose your land. It’s been this way since the beginning of time.
What gives you the idea that a country can wage war without consequences?
LOL , you really need to graduate
You’re likely correct… I probability emphasized it a bit much….
Two fundamentalist entities whose core belief/strategy remains a state/system which is only meant for their respective followers.
There are many Arabs in the Israeli political system. How many Jews/Christian are in ISIS?
“Psst.. Spoils of war, look it up.”
That doesn’t give them any right on their claims though
It gives them EVERY right. If you start a war and then lose that war, do you think there are no consequences?
It’s been this way since the beginning of time.
they can continue to fund and build up their ISIS buddies
Lol, the only people ISIS hates more than the US is Israel.
Psst.. Spoils of war, look it up.
Is there any reason for this modification?
It’s a modification to a multi-year contract.
