The abandonment of the Armstrong breech-loading design led Britain to begin a major program of building rifled muzzle-loaders to equip its fleet. The Armstrong 110-pound gun was succeeded by various RML 7 and 8-inch guns. 7-inch Armstrong breech-loaders under construction at the time of cancellation were completed as RML 64-pounder muzzle-loaders.
Armstrong returned to the manufacture of breechloaders in the 1880s, using an interrupted thread breech with its own "Armstrong cup" and later the de Bange methods of sealing the bore which relied upon the power of the gun's firing to effect the gas seal ("obturation") rather than the manual labour in the 1858 design.

It retained the Armstrong steel barrel surrounded by wrought-iron coils under tension, but replaced the multiple thin wrought-iron coils shrunk around it by a single larger coil (10 in (25 cm) Mark I) or 2 coils (Mark II); the trunnion ring was now welded to other coils; and it eliminated Armstrong's expensive forged breech-piece.

This left two aircraft companies with Armstrong in the name – Vickers-Armstrongs (usually known as just "Vickers") and "Armstrong-Whitworth". The most successful aircraft made by Armstrong-Whitworth in the inter-war period was the Siskin which first flew in 1919 and remained in RAF service until 1932, with 485 produced.
