The Mk 1XB was a converted Mk 1A. The changes were needed because of the weak fuselage of the original Mk 1 and Mk 1As, which had lead to three hull-losses. The Mk 1XB had a reinforced structure and oval windows. The total cycles of those upgraded Comets was however limited. The engines were upgraded to Ghost 50-Mk4 and MTOW was increased to 117K lb. A total of 4 Mk 1As was upgraded to 1XB standard - two of which were those purchased by the RCAF.
The following table summarizes the relevant data of the two Comets which were purchased by the RCAF.
