I really cannot imagine a manned military aircraft being built in the US without an AoA anymore. The USAF's T-7 will have AoA.
That said, I have yet to fly a Boeing airliner that displays the AoA to the pilots. The data is available... but not put on any displays. Maybe Airbus does it?
The U-2 didn't have AoA or any kind of electronic stall warning for a long time. About 20 years ago, we got AoA... we are told it is the AoA hardware from the Navy P-3. We still "fly airspeed" primarily, but the slick part of the system is the tones you get in the headset as you are on final through touchdown. You could fly the whole approach and landing and never look inside. Frankly, the tone setup we have is something I'd put in any aircraft I owned. No need to add anything to your visual crosscheck.
I agree with Jim in that, although AoA popularity is increasing in the GA world, many of the pilots that use it don't seem to understand the basic concepts. There are many pilots in the Cirrus world that post about AoA, and that swear that having AoA is solution to crashing aircraft. Problem solved! I wish they were right.
Alpha Systems seems to be one of the industry leaders. "Cabi" moonlights for them when they are at Oshkosh, and here's a video with him explaining it. If you recognize him, it's because he was the pilot that flew the U-2 with James May from Top Gear back in 2009.
edit: I just watched the video. Their beeps are similar to what we have... but not as good. Cabi says they also have "tones", but I've never heard them.
