<h2>Armament</h2><p>All 105 mm L7, Rh 105, M68 and CN105F1 series tank guns and South African GT7 tank gun.</p><h2>Development</h2><p>The 105 mm APFSDS-T M735 was one of the first rounds of its type to be issued on any large scale to US armed forces tank units. It is still widely used by many other armed forces but has been supplemented by the later M735A1 which utilises a Depleted Uranium (DU, or staballoy) penetrator core in place of the tungsten alloy core used on the M735. Production of the M735/M735A1 ceased in the USA during the 1980s but continues in Egypt . Known Foreign Military Sales (FMS) exports of the M735 were made to Egypt (14,105), Greece (83,957), Japan (400), Jordan (1,400), South Korea (8,577), Lebanon (7,052), Morocco (4,210), Muscat and Oman (5,376), Pakistan (5,000), Saudi Arabia (5,062), Taiwan (3,333), Thailand (14,656), Tunisia (1,674) and Turkey (12,136). Smaller sample batches of less than 100 units were also passed to Austria, Switzerland and the UK.</p><h2>Description</h2><p>The 105 mm APFSDS-T M735 and M735A1 have the same basic construction, consisting of a fixed round with the projectile assembly crimped onto an M148A1B1 cartridge case. The projectile assembly consists of a subprojectile and a sabot. The M735 subprojectile consists of a nickel-steel (maraging steel) body containing a blunt-nosed tungsten alloy core 35 mm in diameter towards the tip, with a pronounced taper towards the tail. The M735A1 has a Depleted Uranium (DU, or staballoy) core. The front part of the body has an aluminium windshield with a steel tip to prevent aerodynamic heating. An aluminium fin assembly is fitted to the rear of the body and contains an M13 tracer, which burns for a minimum of 2.5 seconds, held in place by a threaded plug and disc assembly. The sabot is aluminium and has three 120º segments assembled around the subprojectile body and interfaced with the penetrator body by a series of mating buttress grooves. A stainless steel bourrelet, containing three shear cuts, is screwed onto the forward face of the sabot. A nylon obturator and polypropylene seal is assembled around it and a urethane seal is applied over the rear face. The brass M148A1B1 cartridge case contains approximately 5.67 kg of M30 propellant. An M120 electrical primer is fitted to the base; the primer includes a flash tube extending almost to the tail of the projectile assembly. Before loading, the primer is normally protected by a metal clip over the base of the cartridge case. A barrel wear reducing titanium dioxide liner is secured to the interior wall of the cartridge case. The 105 mm APFSDS-T M735 and M735A1 have a muzzle velocity of 1,501 m/s. The M735A1 penetrator can penetrate approximately 370 mm of armour set at 0º at 1,000 m. The US Army training round for the 105 mm M735/M735A1 is the TPDS-T M724A1. The TPDS-T M724A1 is also produced in Belgium by MECAR SA and in Egypt by the Heliopolis Company for Chemical Industries. In the USA the main producer of the TPDS-T M724A1 is General Dynamics, Ordnance and Tactical Systems (GD-OTS ). The main details for the TPDS-T M724A1 are round weight, 14.52 kg and round length, 838.2 mm. Muzzle velocity is 1,539 m/s using a single-base propellant.</p><h2>Authorised fuzes</h2><p>None involved Equivalent rounds EGYPT</p><p>EGYPT</p><h2>Manufacturer</h2><p>Heliopolis Company for Chemical Industries</p><p>Type: APFSDS-T M735</p><p>Description: Standard US specifications</p>
