GPS III - 10 Hedy Lamarr

Hedy Lamarr was an Austrian-American actress who, with composer George Antheil, co-patented a frequency-hopping spread-spectrum communication system in 1942. Originally developed to guide torpedoes without being jammed, the technology underpins modern wireless communications, including the resilience of GPS signals, Wi-Fi, and Bluetooth.

GPS III-10 was the final satellite in the GPS Block III production run. Originally assigned to Falcon 9, it was moved to Vulcan in mid-2024 after GPS III-07 -- originally slated for Vulcan -- was urgently reassigned to Falcon 9 due to readiness concerns. Following the SRB anomaly on the USSF-87 Vulcan mission in February 2026, which grounded Vulcan for national security payloads, GPS III-10 was returned to Falcon 9. The second stage carried a "Freedom 250" flag in commemoration of the United States's 250th anniversary.
