USS Madera County (LST-905) was a LST-542-class tank landing ship built for the United States Navy during World War II.

The next day the Dominican Republic crisis arose, and upon delivery of her cargo at Roosevelt Roads, Puerto Rico she headed for San Juan where she went on four-hour standby duty.

During the ensuing months she transported ammunition and construction materials to the Republic of Vietnam, off-loading at ports such as Qui Nhon, Da Nang, Chu Lai, and Nha Trang.

Following her December overhaul, Madera County returned to Subic Bay and support of combat operations in South Vietnam, continuing this role through 1969.

Madera County was attached to Landing Ship Squadron 2 (LANSHIPRON 2) and classified as an "in-country" activity, her crew made up of sailors who volunteered for service in Vietnam.

From Da Nang the ship loaded with trucks and transported Marines and supplies to Cửa Việt Base near the Vietnamese Demilitarized Zone.

During the Tet Offensive Madera County was ordered to proceed into Saigon on 2 February 1968 to see if the port was still viable for merchant ships that were backing up at the Vung Tau anchorage.

The ship arrived after going through the "abandoned" heart of Saigon and had to anchor at the Newport Beach LST slip because Army personnel were not present to assist with docking.

That afternoon a party of officers went into Saigon and returned about dusk with a USO tour of NFL players who were stranded at the Capitol Hotel.

Decommissioned (date unknown), the tank landing ship was transferred (leased) to the Philippine Navy on 29 November 1969 and renamed RPS Ilcos Norte (LT-87).
