In 1975, the German Army decided to procure a specialist anti-tank version armed with up to six Euromissile HOT missiles, designated as the Bo 105 PAH-1. A total of 212 Bo 105 PAH-1s were delivered between 1979 and 1984. German Army leaders saw the PAH-1 as a temporary measure only, having originally sought a more capable anti-tank helicopter; they were particularly dissatisfied with the PAH-1's inability to perform nighttime combat missions and its self-protection capabilities; ultimately, the Eurocopter Tiger was developed as a replacement. In 1977, the German Ministry of Defence selected the Bo 105C for its light observation helicopter (VBH) program, leading to the procurement of another 100 rotorcraft.
