The Keystone LB-6 was an improved version of the XLB-6, which was in turn an improved version of the LB-5. The major design changes in the LB-6 were a lengthened fuselage and a modified tail unit. Eighteen aircraft were ordered after the U.S. Army selected it over the Curtiss XB-2 although the first aircraft (S/N 29-10) was diverted for test purposes and became the XLB-9 (and later reconverted to the LB-6 configuration).
