According to a report from The Telegraph, the RQ-180 stealth drone could potentially add up to $100 billion to the $200 billion B-21 bomber contract that Northrop Grumman secured in 2015.

The aircraft has been in operation for 23 years, since 2001. The USAF plans to retire the type in 2027. The highly classified Northrop Grumman RQ-180 will replace it.
