Example: The city used its ARPA funds to repair water mains and expand broadband.
President Joe Biden signed it on March 11, 2021, after it passed through budget reconciliation without Republican votes. Its expanded Child Tax Credit lapsed after 2021. Many economists debate its contribution to the inflation of 2021-2022. ARPA was also the original name of DARPA, the defense research agency.

Radar feature that tracks other vessels automatically and calculates their course, speed and closest point of approach, warning of collision risks. ARPA is required on larger ships.
Example: ARPA showed the fishing boat would pass only 0.2 miles ahead, so the officer altered course.
