The Japanese miscellany

Japanese aircraft armament was characterised by a wide variety of different types most of which used their own unique ammunition. This is partly explained by the fact that the air forces were divided between the army and navy, although a similar situation did not prevent a high degree of commonality in US aircraft guns. Certainly the Imperial Japanese Army and Navy IJA and UN respectively followed wilfully different procurement policies and seemed unconcerned about the benefits of...

Antitank and Modern Heavy Rifles

The first anti-tank AT rifle, the Mauser Tank-Gewehr M1918, was developed towards the end of the First World War in parallel with the MG TuF machine gun which used the same 13 x 92SR ammunition. It was rushed into service to provide infantry with some protection against the Allied tanks until the TuF could be introduced. The M1918 was conceptually very simple a bolt-action weapon just like a scaled-up infantry rifle but 1.68m long and weighing 17.7kg. The steel-cored projectile was claimed to...

Weapons of other nations

Ww2 37x263

The Italian Air Force was unusual in changing very early from RCMGs to HMGs, but rather threw away the lead this might have given them at the start of the war by typically fitting very few of W il A PONS FOll AIR F I ti II TIIV lt i them. As already stated, the Italians adopted the 12.7 x 81SR Vickers cartridge and produced two of their own weapons in this calibre, the Breda-SAFAT and the Scotti, the former being far more important and numerous. They also produced prototypes of two 20mm guns,...

Automatic cannon the mm guns

Www 1930s 40s Japanese Machine Guns

The evolution of automatic cannon that is, of calibres between 20mm and 40mm between the wars can generally be characterised as a long period of casual development until the late 1930s, followed by a frantic rush to re-equip for the impending conflict. As with HMGs, automatic cannon did not find much favour in the anti-armour role, being reserved almost entirely for aircraft or anti-aircraft purposes. There were some exceptions, however. 38, closely related to the FlaK 30 and 38 AA guns Some of...

Longrecoil mechanisms

Push Unlatch Mechanism How Works

The need for the entire barrel bolt unit to recoil a considerable distance, followed by a delay in commencing reloading while the barrel returns into the firing position, gives long-recoil mechanisms a relatively low rate of fire. As a result, weapons using this system are much less common than the short-recoil type. However, the long and relatively soft recoil push puts less strain on the mechanism and makes accuracy easier to achieve while avoiding the need for the whole gun to recoil in its...

The plastic cartridge case

Cased Telescoped Cartridges

Cartridge case design has so far changed much less than projectiles. Despite the practical advantages of the cartridge case it has always been regarded as something of a nuisance by weapon designers. It adds greatly to the weight of ammunition and complicates weapon design because of the need for mechanisms to extract and eject the fired case from the gun. Other types of cartridge case have occasionally been tried, many of them making use of modern plastics. Attempts to produce entirely plastic...

Postwar MM antiaircraft cannon

Oerlikon Gdf D03 Escorter

The search for high-velocity 20mm cannon with a high rate of fire led both Hispano-Suiza and their rivals Oerlikon to develop new cartridges and guns, as described in detail in Chapter 2. The new cartridges, 20 X 139 and 20 X 128 respectively, offer muzzle velocities of around 1,000 m s, while the guns fire at 1,000 rpm, both very significant improvements on the equivalent Second World War equipment. GIAT, Rheinmetall and Mauser have built rival weapons around these cartridges. The army...

M16a1 Naming The Parts

Sectioned Rciufoss 12.7mm Multipurpose projectile The detonator l is mounted in rotor 2 which is in out-of-line-position. Thus the main charge 3 cannot be ignited in case of an accidental initiation of the detonator. The firing pin 4 resp. the hammer is held by a pressure spring 5 and a slotted sleeve which is secured by a coil tape 6 . This coil provides the arming safe distance of the fuze since it prevents the firing pin 4 from hitting the detonator 1 within a certain flight path of the...
