B-21 Low-Observable Restoration Facility (LO Hangar), Ellsworth AFB, SD 4

Awarded 2021-09-17 — 13 days before fiscal year end (Sep 30). End-of-year awards often have compressed timelines and reduced oversight.

This contract has unrealized obligation backlog — funds committed but work not yet performed. This can indicate project delays or budget holds.

Post-award modifications total 200% of the original award. Change orders exceeding 50% suggest scope creep, poor initial estimates, or intentional low-bidding.
