The RK 95 TP (from Finnish Rynnäkkökivääri 95 taittoperä, 'Assault Rifle 95 folding stock'), officially 7.62 RK 95 TP and commercially known as the M95, is a 7.62×39mm Finnish assault rifle adopted in relatively small numbers by the Finnish Defence Forces in the 1990s. [2]
The Krupp guns used prismatic gun powder, the British gun used Pebble-powder. The Krupp 17 cm gun fired with a charge of 11.8 kg, the British 7-inch with 13.6 kg. The results showed that the Krupp 17 cm clearly outclassed the British 7-inch gun. [26] In Japan, the ironclad FusÅ had four 24 cm guns and two 17 cm RK L/25, used as chase guns. [27]
The 15 cm Ring Kanone L/26 or Lange 15 cm Ring Kanone was a 15 cm 26 caliber long Krupp Ring Kanone (RK). It was a rifled breech loader built-up gun with a Krupp cylindroprismatic sliding breech. It was designed based on the idea that for penetrating armor, it might be more effective to increase the charge then to increase the caliber.
The 21 cm RK L/19 was the later name of a rifled breech loader gun of the Prussian Navy. This gun started with a massive gun barrel, cast from steel in one piece. In 1868 a built-up gun barrel version was tested in Prussia and found to be much more powerful. Many of the massive guns were then changed to built-up guns.
The tests with smaller caliber long guns, the 15 cm MRK L/28, the 24 cm L25/5, the 35.5 cm MRK L/25 and the 40 cm MRK L/25 led Krupp to design a whole new series of longer 30 and 35 caliber long guns, the so-called C/80 system. It meant that the characteristics of 24 cm guns of 30 and 35 caliber length had been calculated.
A 24 cm L/22 gun was exhibited by Krupp at the 1876 Centennial Exposition Philadelphia. It was also called a 24 cm gun and had the same absolute length as well as a relative length of L/22, but in fact this was a prototype gun that had a caliber of 240 mm and was configured for using an increased charge and projectiles with copper driving bands.
This increased the velocity of the Woolwich guns and relative to gun weight, they were again more powerful, even though this did not apply to the 21 cm RK L/22. [19] Krupp and the Germans responded by using a new prismatic powder, which allowed the use of a charge of 19 kg (41 lb 14 oz) for the 21 cm RK L/22. [ 20 ]
With regard to the punch of the steel shot of the Philadelphia 24 cm gun, it was noted that per kg of its weight, this was 110.8 kg.m as opposed to 82.0 kg.m for the 24 cm RK L/22. It was also noted that this number of 110.8 was inline with that of 'all known guns of the third construction period' of the Krupp factory, 'like the 35.5 cm MRK L ...
