See, this is the kind of stuff that clearly makes amateur military enthusiasts and Defence blogs go weak at the knees, doubtless sounds impressive to politicians and civil servants, but has no practical purpose to soldiers. It sounds like the kind of vastly expensive overengineering which is killing our equipment programmes.
If that is the only selling point for this piece of kit, then if it's been ignored, good. Explain exactly what the use case is for a 40mm that can switch seamlessly from anti-armour to anti-personnel fire? Is this some ARMA (sorry, VBS) type Cold War virtual scenario where we go weapons free against an enemy attacking in massed tank and infantry formations, like happens in all our exercises and none of anyone's wars since forever? Perhaps using anti-armour rounds to punch a hole in, say, a building and then fire airbursts into the mix?
Real weapons in real wars are used by soldiers, who have human reaction times, rules of engagement, and have to make decisions. Anything that isn't fully automated (no "killing" weapons are, only anti-projectile ones) which operates faster than those core times is a waste of resources. I genuinely cannot think of any realistic scenario where the weapon you describe is likely to be required. At the most basic level, even firing on an IDed enemy static armour + infantry defensive position would require the gunner to fire in bursts, simply for ammunition conservation. Possibly the only real scenario I could think of in which this would have some use would be a single enemy tank advancing in an urban road with close infantry support, and in that case, it is being built for the wrong country: I can't imagine UK ROE which would allow airburst over direct fire in that situation, for fear of accidentally brassing up civilians in the buildings. Moreover, "close infantry support" usually isn't so close as to necessitate seamless fire at one target, because these days there are standoff distances to patrolling with armour, lest you get liquefied by the pressure shock of your own armour's main gun firing, a lesson the US learned in Fallujah when they tried to emulate WW2 / Vietnam tactics and take cover directly behind modern tanks with vastly more powerful guns.
This could go on, but the point is: this is at best a feature of incredibly limited use in practice. Imagine if, instead, BAE had proposed and focused on a 40mm weapon that was X times lighter, had Y more ammunition capacity, was Z time more reliable or easier to maintain, or cost a fraction of the price so the soldiers who used it could also have a range of other kit they need. That would be something any real soldier might get excited about.
It may be that you have described it poorly, or the thing has other useful qualities. But if you are going to write a puff piece about a piece of kit / BAE on these forums, it might be worth doing it about something that has some obvious practical military use.
