The first product of the new company was the P.B.31E Nighthawk which was a carryover from Billing's time for a quadruplane heavily armed and searchlight-equipped home defence fighter. Fitted with a recoilless Davis gun, it had a separate powerplant to power the searchlight.[3] Only the prototype was built, which was found to have insufficient performance to be of any use against Zeppelins. After completion of the Nighthawk Scott-Paine dropped Billing's fixation with anti-Zeppelin defence fighters, and in the hope of gaining orders for flying boats forged a strong relationship with the RNAS through their local liaison officer James Bird.[citation needed]
