Probably yes. The real question is why now are US senators asking the defense department about what craft they have?
The newish committee AARO is basically useless but there are whistle blower protections in place now for anyone who comes forward with information about crash retrieval programs etc.
David Grusch gave a multiple hour interview with Ross Coulthart last month as one of these whistleblowers. News Nation ran an edited hour of that interview. He makes some bold claims and nobody has really come forward to discredit him since. There are allegedly more whistleblowers to come.

Then what’s the purpose of other countries doing the same?
