Lines: 137 Approved: military@amd.com From: nzt1939@dsacg3.dsac.dla.mil (William M. Aldo) With all the new talk on the net about the M1A2, the following data is for posting if you wish, and is supplied by General Dynamics (without permission) ..... [ A little hype-heavy, but enough technical data to justify the length, I think. --CDR] Additional: Newer models of the M1A1 will include 'depleted uranium armor, encased in steel. Combined, these elements will more easily shat- ter and absorb the intensity of projectile hits. Depleted uranium armor has more than twice the density of steel, yet is more ductile. The Abrams' special armor is effective against both kinetic energy and chemical energy, or shaped charge, warheads.' Continuing in the evolution of the M1 series, the M1A2 will be even more lethal and more survivable. A commander's independent thermal viewer (CITV) will give the com- mander 360 degree surveillance. He will be able to see and acquire tar- gets independently of the gunner. An eye-safe CO2 laser rangefinder will improve fire-control performance by enhancing the ability to penetrate fog and other adverse battlefield conditions. A driver's thermal viewer will improve the driver's vision and provide another set of eyes during silent watch operations. A position navigation (Pos/Nav) system will display vehicle position and heading references to the driver and commander, giving them the correct ground location at all times. The most innovative feature of the M1A2 system is the core vetronics system; which is to the close combat weapon system what avionics is to the jet fighter. Instead of separate, hard wiring of components, all controls are linked through two electronic buses; one controlling power, the other data. The M1A2 possesses the inherent high reliability of digital electronics and the redundancy of critical components devoted to combat functions. Data and power are transmitted on a dual buss. For example: digital fire control information is transmitted on the data bus. If one path is interrupted...signals are automatically diverted to a parallel path...maintaining system function with minimum opera- tional degradation. Commander, gunner, and driver can analyze most problems through built-in testing embedded in the system. Significant features will include: * Improved armor * Improved Commander's Weapon Station (ICWS) * Commander's Integrated Display (CID) * Hull-Turret Position Sensor * Improved Suspension * Position/Navigation Sensor (Pos/Nav) * Driver's Thermal Viewer (DTV) * Driver's Integrated Display (DID) * Digital Engine Control Unit * Onboard Malfunction Detection System * Intervehicular Information System * Digital Communication * Single Channel Ground/Air Radio System (SINCGARS) M1A2 ABRAMS - Characteristics Weight: 69.54 Tons Length(hull): 312 Inches Length(gun forward): 387 Inches Turret Height: 93.5 Inches Width: 144 Inches Ground Clearance: 19 Inches Ground Pressure: 15.4 PSI Gas Turbine Engine: 1500 HP Power-to-Weight Ratio: 21.6 hp/ton Hydro Kinetic Transmission: 4 Speed Forward 2 Speed Reverse Speed Maximum: 42 MPH (Governed) ...REMOVE it;-) Cross Country: 30 MPH 10% Slope: 17 MPH 60% Slope: 4.1 MPH Acceleration(0-20 mph) 7.2 Seconds Main Armament: 120mm M256 Smoothbore Cannon Coaxial Weapon: 7.62mm M240 Machinegun Loader's Weapon: 7.62mm M240 Machinegun on Skate Mount Commander's Weapon: 12.7mm M2 Machinegun Cruising Range: 256 Miles Vertical Obstacle: 42 Inches Trench Crossing: 9 Feet NBC System: 200 SCFM - Clean Cooled Air Crew: 4 Men - Commander Driver Gunner Loader ------------------------------------------------------------------------ The M1A2 gets better with improvements in: * Improved and special ammunition to meet the new threat * New displays - better information, faster for Commander, Driver, Gunner * Improved radio system - simultaneous voice/digital transmissions * Other classified improvements Continuing.... Because the M1A2 system is fully integrated, mutual position navigation on the battlefield is now a reality. Each commander is provided with position information on his tank, the tanks in his command network and fixed enemy positions. This permits designated battlefield synchroni- zation of all platoon and company assets. The CITV image and position navigation information are displayed at the commander's integrated display. Position information can be instantane- ously transmitted to other command elements through the SINCGARS radio system. Steer-to navigation data along with system status is transmitted to the driver through the driver's integrated display. This unit combines the operation of three panels into one line replaceable unit. The tank commander's view of the battlefield is enhanced through an entirely re- designed weapon station...offering the tank commander a dramatic increase of his field of view. The M1A2 gunner's primary sight employs a dual axis stabilized head, enabling the gunner to effectively track evasive ground and air targets. Algorithms in the core system calculate target motion and permit the gunner to engage and destroy evasive targets. The gunner's control and display panel has automated ballistic solutions of both ground and air targets. It also has the capability to accommodate smart munitions currently in developement. "The M1A2 tank gives us a 54% increase in offensive capability and 100% increase in defensive capability...the upgrade will put double the number of rounds on target...and double the rate of kill" --- The U.S. Army testimony to the Senate Armed Services Committee in 1989. -- Mark Aldo UUCP: (osu-cis)!dsacg1!waldo INTERNET: waldo@dsac.dla.mil
