Apologies in advance for slight thread derail, but I'll try to bring it back at the end...
The new CITS can display 19 PMCs at one time, can access PMCs via selecting an aircraft subsystem, converts volts and hex code into English values, and provides expanded CMC info (a "real" English message) when something flags. You can save code lists to a card and load it in the jet to avoid hand-jamming all your codes. It's far from perfect but it's a huge step forward, which is how I would describe SB-16 as a whole. Huge leap forward with some potholes that we'll have to deal with.
As for the radar display, that's a Northrop Grumman product (vice Boeing) so it's a separate upgrade (RMIP phase II/III). Still fighting for funding on that one and there are several COAs to include a possible but financially unlikely AESA. I'm actually going to get a look at the prototype RDU replacement next month at the Northrop facility in Baltimore - I'm looking forward to seeing what they've come up with.
The reason these systems are upgraded in the manner that they are is because it is increasingly difficult - nearly impossible, really - to ask for modifications and enhancements that bring new capabilities to 3rd and 4th gen aircraft. The F-22, F-35, and LRSB are sucking up all the acquisition money, so all that's really left is money for sustainment. They key for the ops/test communities in the old-school jets is to leverage sustainment funds in smart ways that will enhance capability.
Let's say you own a video game console - we'll say it's an Atari - and receive "sustainment" money every year to keep your capability of playing video games. Since Atari's and their components aren't being manufactured anymore, you would try to sell the gov't on the fact that to "sustain the capability," you need to purchase a new system (PS4). Obviously with a PS4 comes enhanced performance, but this request still falls under "sustainment." You make this argument by saying that life cycle costs will be reduced because now, instead of taking your broken Atari to some guy in his mom's basement who charges a million bucks to fix it, you can take your PS4 (which since it is new should have fewer problems anyway) to Best Buy if it craps out, or buy much cheaper replacement parts since they're still being manufactured on the open market.
We have to do the same thing with the jets/radars/etc. since there's very little money for true "upgrades" unless you're 5th-gen.
To bring this all the way around - if the USAF can't get costs for poorly negotiated acquisition programs under control, we'll abolish ourselves. It's mind-blowing how poorly we do acquisitions. Almost criminal from a taxpayer point of view.
