 While many offers were received, only a few of the aircraft types on offer were for purpose-designed seaplanes.As it was the clear request of the RNNAS to have a tried and tested seaplane fighter only the bids coming in from Fokker and Nieuport Astra satisfied the requirement.As the cost of both these offers were considered far too high, Johann E. Høver, managing director at Marinens Flyvebaatfabrikk, recommended that a future fighter should be designed and constructed at his factory in Horten.
