The Westbury was built in response to Air Ministry requirement, 4/24 which called for a large heavily armed twin engined fighter. An important part of the requirement was the need to carry two 37mm cannon, for which considerable structural strength was necessary.
Other contenders for the contract failed to meet this requirement, but the whole concept was eventually discarded and and the Westbury did not proceed beyond the prototype stage.
