The Karachi affair (French: affaire Karachi), otherwise known as Agosta Submarine scandal, was a major military scandal that took place in the second administration of Prime Minister Benazir Bhutto, involving the presidencies of François Mitterrand and Jacques Chirac in 1992–97. The scandal involved the payment of massive commissions and kickbacks between France and Pakistan over the negotiations to acquire Agosta 90B-class submarines. The submarines utilized the emerging air-independent propulsion (AIP) proprietary designs, which Pakistan was eager to acquire over the nuclear submarines.
