So the office has been called:

- UAPTF : Unidentified Aerial Phenomena Task Force.

- AOIMSMG : Aerial Object Identification and Management Synchronization Management Group (I think the second Management is a typo).

And is now called:

- UAUPJPO : Unidentified Aerial-Undersea Phenomena Joint Program Office.

(the acronym for which has a distinctly Spanish feel to it, at least to me)

Geez, just call it "Alien Affairs" and be done with it.

Just for fun, I asked OpenAI's GPT-3 text completion to complete this (slightly modified to invite a next name) sentence:

To accelerate progress, the Committee has, pursuant to Section 703, renamed the organization formerly known as: the Unidentified Aerial
Phenomena Task Force; and the Aerial Object Identification and
Management Synchronization Management Group; and the Unidentified Aerospace-Undersea Phenomena Joint Program Office; and which now shall bear the name:

And here's what it said:

The Office for the Identification of National Security Space
Objectives.

The Committee is also concerned that the Office has not been
given the resources it needs to be successful. The Committee
therefore directs the Secretary of Defense to, within 90 days of
the enactment of this Act, submit to the Committees on Armed
Services of the Senate and the House of Representatives a report
on the resources the Office will need to be successful, including
human, financial, and technological resources.

In other words, if GPT-3 has an pulse on the future, the office (will probably be underfunded, and) shall next be called:

- OINSSO : Office for the Identification of National Security Space Objectives

Not actually a bad name.

I kept going because this was so fun. Some more completions (my prompts in italic):

The Committee directs the Office to provide, within 120 days of
the enactment of this Act, a report to the Committees on Armed
Services of the Senate and the House of Representatives that
describes the process by which the Office will identify national
security space objectives. The report should address, at a minimum, how the Office will:

(1) prioritize and integrate information and analysis across the
DoD and Intelligence Community;

(2) leverage the capabilities and expertise of the private sector
and academia; and

(3) ensure the security of information and analysis related to
unidentified aerospace-undersea phenomena.

Notwithstanding the forgoing, the Director of National Intelligence and the Secretary of Defense may jointly determine that it is not possible to complete the report required by this section within the
time period specified. If the Director and the Secretary make such a
determination, they shall submit to the Committees on Armed
Services of the Senate and the House of Representatives a report
that includes a justification for the determination.

In the event of a discovery of a non man-made object that was formerly nonattributed, the Director of National Intelligence and the Secretary of Defense should, as soon as possible but not later than 30 days after such discovery, jointly submit to the Committees on Armed Services of the Senate and the House of Representatives a report on such discovery and the implications for national security.
