Every single B-2 bomber we have are kept at one base, and that base has just one runway.
Here is a link to Google Maps that actually has an image of a B-2 off in the grass with a lot of vehicles on the runway: https://www.google.com/maps/place/Whiteman+AFB,+MO/@38.724381,-93.5493494,166m/data=!3m1!1e3!4m5!3m4!1s0x87c3f05b0abeb0a3:0xd38015c25b32833!8m2!3d38.7289955!4d-93.5605515
I went to Google Maps to confirm that there was just one runway, but then I noticed in a distant view what looked like damage to the runway right in the middle of the whole length. Turns out it was dozens of vehicles sitting out there. Then I saw the B-2 off in the grass with all kind of objects surrounding it.
They are not going to let that runway be used until this investigation is over. Meanwhile the entire fleet is grounded.
From wikipedia:
“The total program cost projected through 2004 was US$44.75 billion in 1997 dollars (equivalent to US$68 billion in 2021). This includes development, procurement, facilities, construction, and spare parts. The total program cost averaged US$2.13 billion per aircraft.”
