- 1 x Rheinmetall M2004 120mm motion-stabilized smoothbore cannon. Feed is automatic via an autoloader, firing at a sustained rate of 22 rounds/minute, faster for short periods. The turret stores up to 50 rounds without resupply. Mix of shells is mission-dependent. A typical anti-armor load is 30% MP-HEAT, 20% HESH, 50% DU-APFSDS-T. See the addendum for listings of the shells. Maximum effective direct-fire range is 5.3km, indirect fire possible out to 16km at maximum accuracy. This weapon is fully recoil-compensated.
- 1 x Rheinmetall M2018 120mm liquid-propelled motion-stabilized smoothbore cannon. Feed is automatic via an autoloader, firing at a sustained rate of 25 rounds/minute, faster for short periods. The turret stores up to 48 rounds without resupply. Enough liquid propellant is carried for a full load, at direct-fire velocities. Mix of shells is mission-dependent. A typical anti-mecha load is 50% HEAP, 30% MKEP/SMDM-C/FAE, 20% SPIGOT. See addendum for full shell listings. Maximum effective direct-fire range is 5.6km (less for HEAP), indirect fire possible out to 18km at maximum accuracy. This weapon is fully recoil-compensated.
- 3 x Stinger II surface-to-air missiles for air defense located on the right top of the main turret.
- 1 x coaxially-mounted 7.62mm machinegun in the main turret. The machinegun has an ammunition capacity for 5000 rounds.
- 1 x 12.7mm machinegun in the commander’s cupola turret. The machinegun has an ammunition capacity for 500 rounds.
- 2×8 Smoke dischargers capable of firing a smoke grenade up to 50m mounted on the top rear of the main turret.
The armor on the front of the Anaconda is composed of a standard Chobham laminar reinforced by a heavy depleted Uranium mesh on the outer plate. Denser than the standard Chobham, this armor was designed to defeat projectiles striking the forward surfaces of main battle vehicles, and is also effective against beam weapons. The armor stops all small arms, heavy infantry weapons fire, and light mecha-mounted weaponry, provides excellent resistance to medium mecha-mounted weaponry and provides good resistance to heavy mecha-mounted weaponry, such as the Centaur’s 120mm smoothbore shells. This impressive front armor was second only to the Monster’s armor in effectiveness, leading combatants to try to target this tank from the sides and rear at all costs.
The armor on the rest of the M-21 is composed of a standard Chobam laminar developed in the late 20th century and improved with the materials science advances made during the Robotech era. This armor was mainly designed to defeat projectiles and other kinetic weapons. The armor stops all small arms, heavy infantry weapons fire, and light mecha-mounted weaponry, and provides excellent resistance to medium mecha-mounted weaponry, such as the Valkyrie’s 55mm APFSDS round, and fair resistance to heavy mecha-mounted weaponry, such as the Centaur’s 120mm smoothbore shells.
The Anaconda provides full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies can provide atmosphere for one week maximum.
The M-21 Anaconda was developed by the United Earth Defense Force (UEDF) to replace the mish-mash of M10 Aztecs, M1 Abrams and Leopard 2s operated by the service in the post war years. The M-21 used more advanced materials to drastically increase the armor capability of the tank to improve its battlefield survivability.
The Anaconda is a conventional tank that makes use of improved materials technology to provide an extremely well-armored assault platform. With the knowledge gained from the SDF-1, materials technology made drastic advances related to the structures needed for variable technology mecha. In a lower risk implementation, these materials were applied to existing technology to increase the armor and significantly reduce the weight of the modern tanks. In a joint venture by Kraus Maffei Destroids GmbH of West Germany and Mitsubishi Heavy Industries of Japan, the Anaconda was developed. The lighter weight, corresponding increase in speed, and ability to withstand a frontal attack by standard anti-tank weapons makes the Anaconda a significant breakthrough in armored combat for its time. This tank used a liquid-propelled upgrade of the successful 120mm cannon used on the M1A1 Abrams and Leopard 2 tanks, and added an autoloader to decrease the crew complement and increase the rate of fire.
For survivability, the ammunition compartment for the main gun has a blast door on the top of the turret similar to the M1A1 Abrams and Leopard 2 tanks, so if the ammo is ignited, it will blow out the top of the tank instead of inside the turret killing the crew. The tank also has an internal fire detection and suppression system.
The success of the Commanchero heavy attack helicopter led the designers to include some air defense missiles in the design to improve the survivability of the tank. UEDF tank crews began referring the Stinger II missiles as “Commanchero-killers” after their successful use in a battle near Buenos Aires. The Commancheros were able to decimate the ranks of ancient Leopard 2 and Abrams tanks, but the Anacondas faired well in the exchange.
A number of versions were developed including an armored recovery vehicle, a minesweeper, a bulldozer and an armored command post.
