The proof of the pudding … or rather, the proof of armour and gunsPosted: July 25, 2013
The following are examples of such armoured targets.
5-inch iron armour
11-inch iron armour
13-inch iron armour
As a result of such experiments, it was possible to draw up a table that compared the resistance to penetration of different types of armour.
Guns were also proofed at Woolwich and the largest ever tested there was the 16-25-inch Breech Loading Mk.I that was manufactured by at Elswick by Armstrongs.
Its specifications were:
- Total Weight: 111 tons
- Calibre: 16.25 inches
- Barrel length: 487.5 inches
- Shells: 1,800 pound Armoured-piercing, Common, and Shrapnel shells
- Elevation: -5° to + 13°
- Muzzle velocity: 2,087 feet/second
- Maximum range: 12,000 yards
The gun was introduced into service in 1885, and was used aboard HMS Benbow, HMS Victoria, and HMS Sans Pareil.
The proof mounting used still exists, and was on display in Woolwich until recently. The barrel is NOT a 16.25-inch but an 18-inch howitzer that was developed towards the end of the First World War.
