Supermarine responded quickly to the unexpected success of the Taipan and the Boomslang was delivered to an expectant public only two years later. Originally intended to address the limited cargo capacity of its sister ship, the design team decided to re-focus on the more exciting area of weapon deployment instead. Misleading the company directors by stressing the need for larger wings to carry a heavier load they promptly forgot to upgrade the fuselage and concentrated on advancing the weapon array. An upgrade to Class 3 weapon mounts on the wings and Class 4 on the Tail was the result and the slight improvements with respect to the hold can be described as marginal at best.
