The Elias XNBS-3 was very similar to the Martin NBS-1. The aircraft had the same basic design, crew configuration, engines and performance as the NBS-1, which had been in service for about four years when the Elias aircraft was first tested in mid-1924. Since the aircraft offered almost no improvements over aircraft already in service (which were outdated themselves), the aircraft never went beyond the prototype testing phase. Only one XNBS-3 (AS 68567) was ordered.
