A single gilding metal or copper drive band encircles the projectile just forward of the case/projectile junction. In both cases the projectile body is a solid hardened steel slug with a flat base and a relatively short ogive. A lightweight aluminium windshield is secured over the ogive of the projectile slug. The projectile base is threaded to accept a tracer, for the M318 the M5A2 or M5A2B1. The same types of tracer may be fitted to the M318A1 along with the M13 . In all cases the red tracer burns for the first 3 seconds of the projectile trajectory. The 90 mm AP-T M318 and M318A1 use different cartridge cases and propellant loads. The M318 uses a 70:30 brass rimmed M19 or M19B1 case with an M49 percussion primer press fitted to the base. The case is loosely filled with 3.9 kg of M6 propellant. The M318A1 uses an M108 or M108B1 case with an M58 percussion primer press fitted to the base. The rimmed case is loosely filled with 3.9 kg of M7 or M30 propellant. In both instances uniform propellant ignition is assisted by an igniter located below the cartridge closure disc. The 90 mm AP-T M318 has a muzzle velocity of 851 m/s and a maximum range of 19,570 m. The 90 mm AP-T M318A1 has a muzzle velocity of 912 m/s and a maximum range of 21,030 m. The Cartridge, 90 mm: TP-T M353, M353A1 and M353A2 are low-cost training rounds ballistically matched to the 90 mm AP-T M318A1. They all use a steel projectile body and the only difference between the three models is the type of cartridge case lining used to reduce barrel wear.</p><h2>Authorised fuzes</h2><p>None involved Equivalent rounds NETHERLANDS</p><p>NETHERLANDS</p><h2>Manufacturer</h2><p>Eurometaal NV</p><p>Type: TP-T</p><p>Description: Standard US specifications as for 90 mm TP-T M353A1.
