HMS Neptune was an ironclad
Ironclad warship
An ironclad was a steam-propelled warship in the early part of the second half of the 19th century, protected by iron or steel armor plates. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, La Gloire,...

, something that the British were not prepared to tolerate. They mobilized much of the Royal Navy in case war did break out and purchased a number of ironclads under construction, including Independencia, in 1878. The Brazilians sold the ship for £600,000, nearly twice as much as the £370,000 paid for Devastation a few years earlier. Another £89,172 was spent to bring her up to the standards of the Royal Navy. In British service she was deemed "a white elephant

It was credited with the nominal ability to penetrate 11.3 inches (287 mm) armour. The muzzle blast of the main guns was more than the deck immediately below the muzzles could stand and the full charge for the guns was reduced from 200 to 180 lb (90.7 to 81.6 kg) of powder to minimize the damage.
