So, with the commissioning of the USS Canberra (LCS-30) in Australia, a couple of news articles subsequently flashed claiming she was the “first U.S. warship commissioned outside of the country.”
About that.
The Yangtze River Patrol of the Asiatic Fleet, especially after 1898, included a series of more than a dozen river gunboats that spent their entire career– with the exception of regular runs to Hong Kong or Cavite for maintenance periods– in Chinese waters. Commissioned U.S. Navy warships, they never saw their “home” country.
This included six captured Spanish gunboats: Elcano, Villalobos, General Alava, Pompey, Callao, and Quiros, that were commissioned in 1900-1903 at Cavite under their old names (and often with old crew members recruited from the locals!)

They generally remained in service into the 1920s.
Others, such as USS Palos (Gunboat No. 16) and her sistership Monocacy (Gunboat No. 17), built for service on the Yangtze, were pre-constructed at Mare Island in 1912; dismantled, then shipped to China where they were laid down at Shanghai Dock and Engineering Co, and commissioned there in 1914.
The sisters were even interned in China during a four-month period in which the U.S. was at war with Germany but China was not.
U.S. Gunboats Palos and Monocacy at Shanghai anchored alongside the Standard Oil Dock, Shanghai, China. The USN gunboats were interned by China in April 1917 and released from internment and returned to duty in August. They would serve into the 1930s and never saw U.S. waters. 80-G-1025942
Six new craft were designed and built in 1928 in Shanghai for the YANGPAT, of three differing sizes: USS Guam and Tutuilla (380 tons) USS Panay and Oahu (450 tons), USS Luzon and Mindanao (560 tons), all of which were commissioned there.
Infamously, Panay was lost 1937 in what many later deemed the first U.S.-Japanese clash of WWII. The remaining five were lost in 1941.

Subsequently, when going back to check on one of the Canberra articles mentioned, the title had been stealth changed to “USS Canberra (LCS-30) became the first US Navy ship in history to be commissioned in Australia” without explanation although the URL remained https://gagadget.com/en/weapons/284710-uss-canberra-lcs-30-became-the-first-us-navy-ship-in-history-to-be-commissioned-outside-of-the-country/
