On December 7, 1941, the USS Oklahoma was attacked and sank at Pearl Harbor. In all, 429 Sailors and Marines were killed. The ship was re-floated in 1943, but sank somewhere in the Pacific as it was being towed. The 10-ton anchor was recovered and brought to Oklahoma City, where it resides today. This anchor and historical monument stand as a reminder of those that died on the USS Oklahoma during the attack on Pearl Harbor. The following text is the inscription on the front of the historical marker that stands next to the anchor. USS Oklahoma Anchor This anchor was one of three that were added during the Navy's modernization of the USS Oklahoma in 1927. Manufactured in 1919 by Baldt Anchor Company in Chester, Pennsylvania. The anchor weighs 19,860 pounds. Thanks to the efforts of Rear Admiral John E. Kirkpatrick, USNR, Ret., the USS Oklahoma anchor has had a home in Oklahoma City since 1960. Originally located near the Civic Center at Couch Drive and Robinson Ave, new construction resulted in the anchor's move to a median at Park Ave and Broadway Ave in 1980. In December 2005, the anchor was moved to it's current location in Campbell Park at 13th and Broadway Ave. This location is just a few blocks north of downtown Oklahoma City.
