The RML 9-inch guns Mark I – Mark VI were large rifled muzzle-loading guns of the 1860s used as primary armament on smaller British ironclad battleships and secondary armament on larger battleships, and also ashore for coast defence. It should not be confused with the RML 9-inch Armstrong Gun, used by the Dutch navy, the Spanish Navy, and other navies.

The 68-pounder cannon was an artillery piece designed and used by the British Armed Forces in the mid-19th century. The cannon was a smoothbore muzzle-loading gun manufactured in several weights, the most common being 95 long cwt (4,800 kg), and fired projectiles of 68 lb (31 kg). Colonel William Dundas designed the 112 cwt version in 1841 and it was cast the following year. The most common variant, weighing 95 cwt, dates from 1846. It entered service with the Royal Artillery and the Royal Navy and saw active service with both arms during the Crimean War. Over 2,000 were made and it gained a reputation as the finest smoothbore cannon ever made.
The RML 7-inch guns were various designs of medium-sized rifled muzzle-loading guns used to arm small to medium-sized British warships in the late 19th century, and some were used ashore for coast defence.

It was intended to supersede the RBL 40-pounder Armstrong gun after the British military reverted to rifled muzzle-loading artillery until a more satisfactory breech-loading system than that of the Armstrong guns was developed.
The ML 8-inch shell guns of 50 cwt, 54 cwt and 65 cwt were the three variants of British cast iron smoothbore muzzle-loading guns designed specifically to fire the new generation of exploding shells pioneered in the early to mid-nineteenth century by Henri-Joseph Paixhans.
The RML 9-pounder 8 cwt gun and the RML 9-pounder 6 cwt gun were British Rifled, Muzzle Loading (RML) field, horse and naval artillery guns manufactured in England in the 19th century, which fired a projectile weighing approximately 9 pounds (4.1 kg). "8 cwt" and "6 cwt" refers to the weight of the gun to differentiate it from other 9-pounder guns.

Brownhill Battery is a former gun battery at Staddon Heights, Plymouth, Devon. It was one of a number of Plymouth fortifications to be recommended by the Royal Commission on the Defence of the United Kingdom in 1859. Construction began in 1861, at the same time as Staddon Fort and other defensive works at Staddon Heights. The battery was completed by 1868, but was left unarmed.
