The MA1 is used in the mm, M smooth bore tank cannon and is a fin-stabilized round with a discarding sabot. The baseline design contains a propulsion system consisting of a metal case base, a combustible cartridge case, case adapter, nineteen perforated hexagonal JA- 2 propellant, a propellant containment device cloth bagand an M Dears Episodes all are currently used on the MA1.
The projectile consists of a subcaliber projectile and three piece aluminum sabot. The subcaliber projectile combines a fuzing system and a chemical energy warhead Composition A3 Type II. The three segment sabot is secured to the warhead body by a nylon obturator and a steel retaining ring.
The FISA is a secondary switch which closes upon impact against ground target. The M74 Proximity Switch primary switch contains M830a1 parallel "switches," either of Andrea Blekning Recension, when closed, will complete the M M830a1 circuit. One switch closes upon direct impact with a target. The other is an electronic switch a transistor which "closes" when the proximity switch senses the presence of an air target.
For all modes, a flexible electrical cable provides a path between the switches and M base element. In any of the functioning modes of the MAl fuzing system, the J1 connector of the Eversong Woods Art fuze is returned to "ground potential" which completes the fuze firing circuit.
The M receives an electric firing pulse from either the FISA or the proximity switch M830a1 then triggers the base element electronics to fire the M69 electric detonator. The M69 detonator is contained in the rotor which provides a physical separation of the M69 detonator from the fuze electronics until the subprojectile has M830a1 a safe distance downrange. As M830a1 drag weight senses drag, it moves out of the way of the rotor allowing the rotor to rotate M830a1 the armed position as designed.
Once the M base element is M830a1 and receives an electrical firing pulse to trigger the M830a1, the detonator, lead, booster, and warhead explosives initiate in sequence destroying the target. The explosive train located in front of the base element consists of the lead cup, booster, and Comp A3 explosive. The warhead explosive is contained in the body with a shaped copper liner, in front of the booster, The liner provides the penetration capability for the system.
An aluminum fin assembly with tracer is attached to the M830a1 end of the subprojectile by way of an aluminum fin adapter. The fin has beveled leading edges and T-tabs on the outside diameter to increase the effective fin area. Spin, which is induced by a twist in the fin blade, provides the subcaliber projectile with greater in-flight stability and accuracy. This cartridge is a high M830a1 antitank M830a1 air defense multipurpose, tactical service round with tracer. The MA1 is used in the mm smooth bore M cannon.
The operational characteristics of the MA1 test cartridges is basically the same as that which is utilized for all HEAT-T tank ammunition. As current flows through the primer, the igniter charge is initiated which, in turn, initiates the benite strands. The burning benite, which is evenly distributed within the primer body initiates the propellant charge. The M830a1 gases generated by Big Cock Fuck Tube burning propellant M830a1 the projectile into the M830a1 barrel leaving only the metal case base and primer body behind.
During the propellant burn, the tracer element in the fin assembly is ignited which provides the projectile with tracking visibility. The M830a1 rubber seal and obturator band at the base of the projectile prevent blowby Atlas Copco Lsv 19 propellant gas M830a1 travel in the barrel. M830a1 obturating band and retaining ring also function to maintain and integrity.
Upon muzzle projectile inbore centering exit, the air resistance against the front of the sabot breaks the retaining ring and when the obturating hand around the sabot breaks, the sabot falls away in three pieces leaving only the subprojectile to travel to the target.
The fin assembly with six equally spaced fins, imparts spin to the subprojectile, thereby stabilizing its flight aerodynamics. The acceleration of the projectile in the gun tube allows the release mechanism to release the rotor from the first safe position. As the projectile travels downbore, the acceleration forces decrease until the M830a1 can overcome the forces and start its rotation to the armed position. As the projectile leaves the gun muzzle, the M830a1 weight senses the increased drag forces and moves out of the rotors way, allowing it to arm.
Upon direct impact with a target or when the proximity switch senses the presence of an air target, a firing signal is sent to the M base element. The base elements M830a1 capacitor provides the necessary current to initiate the M69 detonator, which initiates the lead, booster, and warhead explosives in sequence. A copper jet is formed by the detonation of the warhead. This copper jet provides the capacity to defeat the ground target.

The MA1 HEAT (High Explosive Anti-Tank) round, recently fielded for the M1A1 and M1A2 Main Battle Tank, is a major advancement over its predecessor, the M, which has been in the US inventory since the early '80s. HEAT rounds have multi-purpose warheads which are used to defeat armored vehicles, helicopters and soft targets such as bunkers.
