Vrenn Yes, but many things the US makes strictly for export, with no intent on using them for themselves.
And I can bring up yet another one with little thought.
In 1978, we started building 4 new destroyers for the Royal Iranian Navy. These were to be based on the Spruance class, but to include major changes, including a vastly improved HVAC system to deal with the heat in the Persian Gulf. And less emphasis on ASW than the Spruance class, with more emphasis on air defense and surface warfare capabilities.
But after the Iranian Revolution, the new government sent a letter to the State Department stating that they no longer wanted the ships. So now the Navy was stuck with 4 ships that it did not really want. This started the saga of one of the most unique classes of ship in the US Navy, known officially as the "Kidd Class Destroyer". But it was most commonly known as the "Dead Admiral" class, as each ship was named after an Admiral that had died in battle. Or the "Ayatollah class", as they were for Iran, but the Ayatollah cancelled the contract.
Admiral Kidd, who died on his flagship, the USS Arizona. Admiral Callaghan, who died during the surface battle at Guadalcanal on the USS San Francisco. Admiral Scott, who also died at Guadalcanal on the USS Atlanta. And finally, Admiral Chandler, after a kamikaze struck the USS Louisville off of Luzon.
But because of their modifications, they spent most of their career in the Persian Gulf, ironically poised against Iran and Iraq. And as a pre-AEGIS system, they also became a test bed for future AEGIS upgrades and configurations.
Finally in 1999 they were retired after a proposal to sell them to Australia fell through. And after a similar deal to sell them to Greece failed, they were bought by Taiwan. Where the four ships are known as the Kee Lung class destroyer.
This was yet another item that the US never intended on using, it was literally built in the window right before the Arliegh Burke class destroyers, which was from the inception to have been a fully AEGIS class ship. This was made for export, so had some parts that were compatible, but many more that were not. The US was only using them because the purchaser basically ceased to exist between keep laying and delivery.
