<h2>Armament</h2><p>100 mm D-10 series tank guns (including NORINCO Type 59 ); 100 mm field gun BS-3; 100 mm KS-19 anti-aircraft gun; NORINCO 100 mm field gun and 100 mm anti-tank gun Type 73; 100 mm Field Gun M53 ; 100 mm towed anti-tank gun M1977 ; 100 mm towed anti-tank gun M1977 ( Romania ); 100 mm Coast Gun ( Yugoslavia ).</p><h2>Development</h2><p>For many years the 100 mm AP-T 53-BR-412 and its improved variant the AP-T 53-BR-412B, were the main anti-armour projectiles fired from D-10 series tank guns. The 53-BR-412 was introduced into service together with the D-10 gun, while the 53-BR-412B first appeared during the 1950s and replaced the earlier model. It is very likely that these two rounds are no longer in production. However, the 53-BR-412B is still marketed by Egypt and Romania , while in Yugoslavia the 53-BR-412B was offered for export sales as the AP-T M65 , although the status of this round is now uncertain. The complete round using the 53-BR-412B projectile is the 53-UBR-412. A later round using the same projectile is known as the 3UBR-3. Romanian rounds in this calibre include the AP-T BR-412B and the so-called APC-T BR-412D.</p><h2>Description</h2><p>The 100 mm AP-T 53-BR-412 and 53-BR-412B rounds are both fixed, with the projectile rigidly secured to the brass cartridge case by a single 360º crimping ring, engaging in a single cannelure located between the two copper drive bands on the projectile. The two projectiles mainly differ in their hardened steel body shapes. The 53-BR-412 has a pointed solid nose while the 53-BR-412B has a blunt nose concealed under a light-alloy windshield, to preserve the ballistic outline. Both projectiles have a small internal cavity close to the base which contains 64 g of A-IX-2 (RDX/Aluminium) for behind-armour effects, ignited after a short delay by a base detonating MD-8 fuze made of steel. A protrusion from the base houses a tracer element. The brass or lacquered steel cartridge case contains approximately 5.5 kg of NGH propellant in stick form. A KW-13 or KW-13U percussion primer is threaded into the base. Brass cases are made from MK-75 brass and weigh 8.5 kg. The flange diameter is 147.5 mm. Both projectiles have a muzzle velocity of approximately 900 m/s. The 53-BR-412 can penetrate 135 mm of vertical armour at 1,000 m and the 53-BR-412B penetration at the same range is 185 mm. A 100 mm AP-T 53-BR-412B projectile has a 77 per cent chance of hitting a static tank sized target at a range of 1,800 m under ideal conditions; performance under combat conditions may be much lower.</p><h2>Authorised fuzes</h2><p>BD MD-8, MD-8M1 or DBR-2 Equivalent rounds EGYPT</p><p>EGYPT</p><h2>Manufacturer</h2><p>Heliopolis Company for Chemical Industries</p><p>Type: AP-T</p><p>Description: Exact model uncertain but believed to be based on 53-BR-412B.
