SCU Nimitz kinematics study (Knuth/Powell/Reali 2019).

Peer-reviewed SCU paper estimating lower-bound accelerations of 75g to >5000g for the Nimitz objects, with no sonic booms or air disturbance - concluding either error/fabrication or technology beyond known craft.
Knuth, Powell & Reali (2019) used witness accounts and reported radar behavior to bound the objects' performance, deriving accelerations from 75g up to over 5000g without observed signatures. The authors argue the quality and number of witnesses and sensors favor the 'advanced technology' interpretation. Skeptics note the inputs (especially uncalibrated FLIR geometry and unreleased radar) carry large uncertainties, so the extreme g-figures are sensitive to assumptions.
