Soyuz 19
Extracted from the Wikipedia article Apollo–Soyuz.
The Americans referred to the flight as the Apollo–Soyuz Test Project (ASTP), while the Soviets called it Experimental flight "Soyuz"–"Apollo" (Russian: Экспериментальный полёт «Союз»–«Аполлон», romanized: Eksperimentalniy polyot "Soyuz"–"Apollon") and designated the spacecraft Soyuz 19. The unnumbered Apollo vehicle was a leftover from the canceled Apollo missions program and was the final Apollo module to fly.
