RML 9 Inch 12 Ton Gun
The RML 9-inch guns Mark I – Mark VIMark I – Mark VI = Mark 1 through to Mark 6. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. Hence this article describes the six models of RML 9-inch guns. 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. Design The rifling was the Woolwich pattern of a relatively small number of broad, rounded shallow grooves : there were 6 grooves, increasing from 0 to 1 turn in 45 calibres (i.e. ). Mark I, introduced in 1865, incorporated the strong but expensive Armstrong method of a steel A tube surrounded by multiple thin wrought-iron coils which maintained the central A tube under compression, and a forged steel breech-piece. 190 were made ...

Simon's Town
Simon's Town (), sometimes spelled Simonstown, is a town in the Western Cape, South Africa and is home to Naval Base Simon's Town, the South African Navy's largest base. It is located on the shores of Simon's Bay in False Bay, on the eastern side of the Cape Peninsula. For more than two centuries, it has been a naval base and harbour (first for the British Royal Navy and now the South African Navy). The town is named after Simon van der Stel, an early governor of the Cape Colony. Topography The land rises steeply from near the water's edge and the town is boxed in along the shoreline by the heights above. The small harbour itself is protected from swells by a Breakwater (structure), breakwater that was built with thousands of huge blocks of sandstone quarried out of the face of the mountain above. Simon's Town is now in effect a suburb of the City of Cape Town Metropolitan Municipality. The Simon's Town railway station is the terminus of the Southern Line (Cape Town), Southern ...

Palliser Shot And Shell
upPalliser shot, Mark I, for 9-inch Rifled Muzzle Loading (RML) gun Palliser shot is an early British armour-piercing artillery projectile, intended to pierce the armour protection of warships being developed in the second half of the 19th century. It was invented by Sir William Palliser, after whom it is named. History Major Palliser's shot, approved 21 October 1867, was an improvement over the ordinary elongated shot of the time. It was adopted for the larger types of rifled muzzle-loading guns rifled on the Woolwich principle (with three rifling grooves). Palliser shot in many calibres stayed in service in the armour-piercing role until phased out of (British) service in 1909 for naval and fortress use, and 1921 for land service. At the Battle of Angamos (8 October 1879) the Chilean ironclad warships fired twenty 250-pound Palliser gunshots against the Peruvian monitor '' Huáscar'', with devastating results. It was the first time that such piercing shells were used in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rotating Gas-check
A rotating gas-check (more commonly known as an automatic gas-check) was a copper plate that automatically attached itself to a specially designed studless projectile of rifled muzzle-loading ("RML") artillery, sealing the escape of gas between the projectile and the barrel and imparting axial rotation to the projectile.Ref 1881 pp. 188-190; Ref 1887A pp. 155-156 Gallery Image:RML 12.5in Studless Palliser Shell Mk I with Automatic Gas-Check.JPG , 1 Image:RML 12.5in Studless Common Shell Mk I with Automatic Gas-Check.JPG , 2 # RML 12.5in Studless Palliser Shell Mk I with Automatic Gas-Check # RML 12.5in Studless Common Shell Mk I with Automatic Gas-Check See also * Gas-checks in British RML heavy guns Gas-checks were attachments to ammunition that revolutionised the performance of RML heavy guns.

Shrapnel Shell
Shrapnel shells were anti-personnel artillery munitions that carried many individual bullets close to a target area and then ejected them to allow them to continue along the shell's trajectory and strike targets individually. They relied almost entirely on the shell's velocity for their lethality. The munition has been obsolete since the end of World War I for anti-personnel use; high-explosive shells superseded it for that role. The functioning and principles behind shrapnel shells are fundamentally different from high-explosive shell fragmentation. Shrapnel is named after Lieutenant-General Henry Shrapnel, a Royal Artillery officer, whose experiments, initially conducted on his own time and at his own expense, culminated in the design and development of a new type of artillery shell. Usage of the term "shrapnel" has changed over time to also refer to fragmentation of the casing of shells and bombs, which is its most common modern usage and strays from the original meaning. ...

Gas-checks In British RML Heavy Guns
Gas-checks were attachments to ammunition that revolutionised the performance of RML heavy guns. The first generation of RML heavy guns began entering service in about 1865. They all had Woolwich rifling and relied on studs on the projectiles for rotation. Gas-checks were first introduced in 1878 or soon after. They significantly reduced wear on the guns while also increasing their range and accuracy. Before long, studless ammunition was being manufactured for these guns, using gas-checks for projectile rotation. Gas-checks also facilitated a switch to the second generation of RML guns which used polygroove rifling and only supported studless ammunition. Introduction The first RML heavy guns were introduced into British service in about 1865. By 1878, 11 models of Woolwich rifled guns had been introduced, ranging from 7 inches to 12.5 inches. Unfortunately, Woolwich rifling had a major defect, namely, that hot powder gas escaping around the ammunition ("Windage") caused excessive ...

Rock Of Gibraltar
The Rock of Gibraltar (from the Arabic name Jabal Ṭāriq , meaning "Mountain of Tariq ibn Ziyad, Tariq") is a monolithic limestone mountain high dominating the western entrance to the Mediterranean Sea. It is situated near the end of a narrow -long promontory stretching due south into the Mediterranean Sea and is located within the British territory of Gibraltar. The rock is 27 km northeast of Tarifa, Spain, the southwestern tip of Europe on the Iberian Peninsula. The rock serves as a fortress and contains a labyrinthine network of man-made tunnels known as the Tunnels of Gibraltar. Most of the Rock's upper area comprises a Gibraltar Nature Reserve, nature reserve which is home to about 300 Barbary macaques in Gibraltar, Barbary macaques. It is a major tourist attraction. The Rock of Gibraltar, the northern of the two historic Pillars of Hercules, was known to the Ancient Romans, Romans as ''Mons Calpe'' ("Mount Calpe"); the southern Pillar of Hercules on the African side o ...

Spy Glass Battery
Spy Glass Battery or Spyglass Battery was originally a high angle artillery battery in the British Overseas Territory of Gibraltar. The battery is mounted high on the rock to give extra range and protection. The battery was still in use during the Second World War as a listening post and site for a Bofors Gun. Description The six RML 10-inch 18-ton guns here were seen as the culmination of the idea of "retired batteries". Originally most of Gibraltar's guns were on the coast but Major General Sir John Jones realised that setting them higher up the Rock gave them more range and made them more difficult to hit. The six guns here and at the other ridge batteries were as high as guns could be placed. This battery however was different in that this was a high angle battery. There was a growing realisation that the thickness of the armour carried by battleships at the end of the nineteenth century meant that they were almost impossible to penetrate with even the largest gun. A new gun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
