When the Ministry of Defence, under its new secretary Franz Josef Strauss, learned from the HS.30 evaluation on the proving grounds in 1958 about multiple shortcomings of the vehicle, it became increasingly impatient with Hispano-Suiza and cut the initial order of 10,680 down to 2800, with 1089 to be built by Leyland in the United Kingdom, the rest by Henschel and Hanomag in Germany. A settlement with Hispano-Suiza was reached in 1960, with the german state paying 40 million DM to compensate for investments and lost revenue.
