If we're talking first USN supersonic aircraft it seems to be somewhat uncertain - Googling it gets claims for the F4D, the F7U, the F8U & the F11
Seems to depend on how you define it - level flight/dive/first flight/ first supersonic flight/first in service
I quoted Bill Gunston who's normally quite reliable.
Not a big worry 80 years on TBH
