The newly flown airship R36, G-FAAF, even larger than the R33 with a gas capacity of 2,101,000 cubic feet, performed further duties for the police over the Ascot Races on June 14, 1921. Again this sortie was intended by the government as a means of creating interest in off- loading the airships into private hands. In comparison with the R33, the R36 was a far better proposition for the police duty in that it featured better accommodation. Modified to provide greater passenger space, the rear of the control car included a roomy section able to take some two dozen passengers in addition to the crew of 37, it was hoped that many more influential people would be in a position to push for the sale of the craft.

The Metropolitan Police deployed airships to monitor traffic at the Derby and Ascot in 1920-1.
