Not applicable, as the airport is not closed. The 'closed' status found in some databases for the identifier 'US-0260' is likely a data error. The facility has been in continuous operation under U.S. Navy control and was never permanently closed.

The site is an active and critical military airfield known as NALF San Clemente Island (ICAO: KNUC, FAA LID: NUC), located on San Clemente Island, California. It is operated by the U.S. Navy as part of Naval Base Coronado. The airfield features a 10,000-foot runway capable of handling large military aircraft like the C-5 Galaxy and C-17 Globemaster, as well as tactical aircraft and helicopters. Its primary mission is to support the various training activities on the island, including extensive training for U.S. Navy SEALs and naval aviation units.

San Clemente Island has been owned and operated by the U.S. Navy since 1934. The airfield was developed to support military operations and training. Historically, it has been a crucial asset for:
- **Naval Aviation Training:** The airfield serves as a practice field for pilots, particularly for simulated aircraft carrier landings (Field Carrier Landing Practice - FCLP).
- **Logistical Hub:** It provides the primary means of air transport for personnel and supplies to the remote island.
- **Supporting the Range Complex:** The airfield is integral to the San Clemente Island Range Complex, the U.S. Navy's only remaining ship-to-shore live-fire bombardment range. It supports a wide variety of training exercises for the Navy, Marine Corps, and other agencies.

Not applicable. The airport is an active military facility and is a vital component of U.S. Navy training infrastructure. There are no plans for its closure.
