B-21 Raider, Until The Year 2100

No, It's not 9:00 PM or 2100 hours but the year 2100. The B-21 Raider will fly for the next seventy-five years until the year 2100. Calculating the B-21 will enter its service in the year 2025 makes for a neat estimation of 75 years since the B-52 is counted on for 80 years of service. So the B-21 could be for 75 years of service. Sounds reasonable.

The B-21 objective currently stands at a 100 unit USAF proposal. If costs are contained and an open architecture remains, then more might be built during the next 30 years. It could amount to 200 units produced by the year 2080 for the Air Force. That's how many it will need replacing its remaining B-52, B1, and B-2 bombers. Of course, the B-21 itself will need replacing from its early flying copies as technology and weapons evolve. The B-21 must learn to live in its initial skin having an ability to insert upgrades and functionality.  The Raider has to become the "new" B-52 without having following on Bomber proposals very 10 years. Doing a Bomber proposal every10 years will "break the US Bank". The Air Force must adapt to one bomber concept and not keep rolling out another we should have done this prototype every so often. It must work within its own skin as well!

The B-21 bomber is perceived as that one bomber and it will not be replaced by at least fifty years unless it morphs with technological progressions. It will reach 200 units built in the long run.
