Yes. The Commonwealth of the Northern Mariana Islands (CNMI) became a US commonwealth in 1978 and residents are US citizens, although they elect a non-voting delegate to the US House of Representatives.
Tinian's North Field was the largest airbase of WWII, and on August 6 and August 9, 1945, the B-29 bombers Enola Gay and Bockscar took off from there to drop the atomic bombs on Hiroshima and Nagasaki.
The official seat of government is Capital Hill on Saipan, although Garapan is the main commercial town. Saipan is the most populous island of the commonwealth.
