M2A3 and M3A3 Bradley Fighting Vehicle Systems (BFVS)
The mission of the Bradley Fighting Vehicle [BFV] is to provide mobile protected transport of an infantry squad to critical points on the battlefield and to perform cavalry scout missions. The BFVS will also provide overwatching fires to support dismounted infantry and to suppress or defeat enemy tanks and other fighting vehicles. The Bradley Fighting Vehicle is a fully armored, fully tracked vehicle designed to carry Mechanized Infantry into close contact with the enemy. It possesses sufficient cross-country mobility to keep up with the Abrams Main Battle Tank, medium and long-range firepower capable of defeating any vehicle on the battlefield, and is adequately armored to protect the crew from artillery and small arms threats. During World War II, the vehicle's namesake, General Omar Bradley, was known as the "GI General".
The Bradley is able to close with and destroy enemy forces in support of mounted and dismounted Infantry and Cavalry combat operations. The Bradley Fighting Vehicle family currently consists of two vehicles: the M2 Infantry Fighting Vehicle and the M3 Cavalry Fighting Vehicle. Just as with its predecessor, the M113 family, the Bradley will eventually be the platform for a wide range of support vehicles.
Unlike the M113 family of vehicles the Bradley replaces, this is not simply a "battle taxi". The Bradley is a sophisticated weapons platform capable of providing tremendous firepower in direct support of the Infantry it carries. The role of the Bradley is to
? Safely transport Infantry to critical locations on the battlefield;
? Provide fire support to cover their dismounted operations, and
? Destroy enemy tanks and other vehicles that may threaten the Infantry it carries
The Bradley?Ts main armament is the M242 25mm "Bushmaster" Chain Gun, manufactured by McDonnell Douglas. The M242 has a single barrel with an integrated dual-feed mechanism and remote ammunition selection. Either armor piercing (AP) or high explosive (HE) ammunition may be selected with the flick of a switch. The Gunner may select from single or multiple shot modes. The standard rate of fire is 200 rounds per minute, and has a range of 2,000 meters (depending on the ammunition used). A wide range of ammunition has been developed for this weapon, making it capable of defeating the majority of armored vehicles it is likely to encounter, up to and including some main battle tanks. The M240C machine gun, mounted to right of the Bushmaster, fires 7.62mm rounds.
When facing heavier enemy armor the Bradley relies on the TOW Anti-Tank Missile, manufactured by the Hughes Aircraft. Launched from a smooth tube launcher, the missile?Ts wings and tail fins are folded inside its body until launch. Two of these missiles are carried ready to fire in a collapsible, armored launch rack on the left of the turret. The Bradley must stop in order to fire these missiles, which are them reloaded by the Infantrymen in the back of the vehicle, using a special hatch which provides armor protection during the reload operation. The missile is equipped with a massive shaped charge, high explosive warhead and is propelled by a two-stage solid propellant motor. The range of the TOW missile is nearly 4 kilometers and the missile will reach a speed of almost Mach 1 on its way to the target. This weapon is capable of destroying any armored vehicle in existence today and is deadly accurate.
The wide tracks and 600 horsepower turbo-diesel power plant give the vehicle the mobility it needs to keep up with the Abrams, and keep the soldiers it carries out of harms way. In order to fulfil the requirement for rapid worldwide deployability, the Bradley can be transported by truck, rail, ship and transporter aircraft. In addition, all Bradleys are amphibious. Early models were equipped with a water barrier, which is erected by the crew before entering the water ?" a procedure that takes about 30 minutes. Later models have an inflatable pontoon, which fits on the front and sides of the vehicle. This pontoon is inflated in about 15 minutes, and is continuously pressurized during operation. The pontoon is compartmentalized to provide protection against sinking in the event of rupture of the pontoon. Water propulsion is provided by tracks which propel the vehicle at about 4 MPH.
The vehicle's reliability, survivability and lethality has surpassed initial expectations. Of the 2,200 Bradleys involved in Operation Desert Storm, only three were disabled. In fact, more enemy armored vehicles were destroyed by Bradleys than by the Abrams Main Battle Tanks!
The M2 Infantry Fighting Vehicle [IFV] is a fully tracked, lightly armored vehicle that offers significant improvements over the M113 series of armored personnel carriers. The M2 possesses greater power, greater acceleration, and an advanced suspension for a significant increase in cross-country speed. Like the M113, the primary purpose of the M2 is to carry infantryman on the battlefield, and transport and support them with fire if necessary. The M2 Bradley carries a crew of three (Commander, Gunner & Driver) and a six-man Infantry section into combat.
The M3 Cavalry Fighting Vehicle [CFV] is exactly the same chassis as the M2 IFV with some minor internal differences. The M3 is a cavalry/scout vehicle, instead of carrying 6 dismounts in the payload compartment, the M3 carries a pair of scouts, additional radios, ammunition, and TOW and Dragon or Javelin missile rounds. In fact, the only noticeable differences between the M2 and the M3 are that the external firing ports for the squad M16s are absent on the M3.
By the end of 1994 the Army had produced a total of 6,724 Bradleys, 4,641 in the M2 Infantry configuration and 2,083 in the M3 Cavalry configuration. Three versions of the M2/M3 have been procured: 2,300 "basic," or A0 Bradleys; 1,371 A1 Bradleys which incorporates the TOW 2 missile subsystem; and 3,053 A2 "high survivability" vehicles. Currently, the Army is conducting depot conversion of A0 and A1 Bradleys to the A2 configuration, modifying 1,423 A2s to the A2 ODS configuration, and preparing to upgrade 1,602 A2s to the A3 configuration. M2/3A0s and A1s will continue to be upgraded to the A2 configuration in FY96. Selected M2/3A2s will be modified with the ODS upgrade pachage through FY02. The First Unit Equipped (FUE) for the A2 ODS variant was FY96. The M2/3A3 vehicle configuration is in EMD with FUE scheduled for FY00.
The M2A3 and M3A3 Bradley Fighting Vehicle Systems (BFVS) are improved versions of the M2A2 and M3A2 BFVS. The BFVS-A3 includes enhancements intended to improve lethality, mobility, survivability, and sustainability. Additionally, these enhancements are intended to provide increased situational awareness and digital command and control capabilities necessary to provide information superiority to the dominant maneuver force. The Bradley Fighting vehicle and the Abrams Tank are the two central components of the dominant maneuver digital force.
The M2A3/M3A3 model of the Bradley will facilitate enhanced command and control, greater lethality, and provide mobile protected transport of an Infantry squad, and Cavalry crewmen to critical points on the battlefield. M2A3/M3A3 will facilitate mechanized Infantry, cavalry scout, and other claimant (Bradley equipped Fire Support and Stinger Teams) missions in the 21st Century. Upgrades include advanced technology in the areas of command and control, lethality, survivability, mobility, and sustainability required to defeat current and future threat forces while remaining operationally compatible with the Abrams main battle tank. The M2A3/M3A3 will provide overwatching fires to support the dismounted infantry and suppress/defeat enemy tanks, reconnaissance vehicles, IFVs, armored personnel carriers, bunkers, and attack helicopters. In the Cavalry role, it will be used to conduct reconnaissance operations, economy of force, and screening missions. It will be employed in Combined Arms units alongside the M1A1 D and M1A2 SEP tank.
The A3 upgrade to the Army?Ts Bradley fighting vehicle system is a major component of the Army digitization initiative, designed both to complement the capabilities provided by the M1A2 SEP and to incorporate needed enhancements identified during the Gulf War. The M2A3/M3A3 will be equipped with a digital electronic architecture incorporating on-board subsystem monitoring, diagnostics/ prognostics, and an Army Technical Architecture (ATA) compliant Command and Control software suite that is fully interoperable with M1A2 SEP and M1A1 D tanks, and other Force XXI digitized platforms. When equipped with upgraded Bradleys, mechanized infantry units will be able to share battlefield data with M1A2 SEP-equipped armor units. The digitization upgrades will improve both situational awareness and sustainability through automated fault reporting and diagnostics. The A3 upgrade will also increase the lethality of the Bradley by adding an improved fire control system and a commander?Ts independent thermal viewer.
Increased funding for Stryker and Future Combat Systems (FCS) came as a result of Army decisions in 2002 to terminate or restructure some 48 systems in the FY ?~04-?T09 Program Objective Memorandum (POM) long-term spending plan. Among the systems terminated were: United Defense?Ts Crusader self-propelled howitzer and the A3 upgrade for the Bradley Fighting vehicle, GD?Ts M1A2 Abrams System Enhancement Program, Lockheed Martin?Ts Army Tactical Missile System Block II and the associated pre-planned product improvement version of Northrop Grumman?Ts Brilliant Anti-armor (BAT) munition, Raytheon?Ts Stinger missile and Improved Target Acquisition System, and Textron?Ts Wide Area Mine.
BFVS-A3 enhancements include
? a vehicle control and operation system to control and automate many crew functions and to enhance situational awareness by transmitting, receiving, storing, and displaying digital messages. This digital capability is to be compatible with all components of the combined arms team.
? the improved Bradley acquisition system (IBAS) and commander's independent viewer, both 2nd generation FLIR's, to improve target acquisition and target engagement.
? a position navigation system with GPS receiver to enhance situational awareness.
Most of the modifications to the Bradley take place inside the vehicle and its turret. Although the turret of the A3 is smaller than the A2's, additional components and software to be installed increase the A3's ability to "shoot, move, and communicate". Moreover, functional improvements are to be made to the A3's electrical power system, Nuclear Biological Chemical protection system, 25mm enhanced gun system, situational awareness capability and its navigational systems.
Electrical power to the A3 is segregated such that many of the components in the A3 can continue to operate despite the failure of other components. Power will be supplied by a 400-ampere voltage and current-regulated generator connected to six hull batteries and one 24-volt turret battery.
The 25mm enhanced gun system will have two types of barrels, nitride and chrome. The gun uses the chrome-lined barrel to compensate for the higher temperatures when firing the new depleted uranium penetrator and other service ammunition. Removable link bridge plates will be installed on the feeder, replacing the old permanent bridge plates to ease the removal of jams and aid in cleaning out debris and/or dust build-up. Also, the manual safe switch will now travel approximately 30 percent beyond center when placed in the fire position to prevent the switch from jumping back to the safe mode when firing a weapon.
The upgrade will also touch on the troop compartment which will be reconfigured to accommodate 10 soldiers, consisting of a three-man crew and seven dismounts. The dismount squad leader will have his own display screen in the back of the A3 so that he and his dismounts can see what the Bradley commander (BC) and gunner see through their sights. The BC will also have the added advantage of a "target designator" enabling him to bring his gunner's line of sight or view of the battlefield online with his own at the push of a button. This way if the BC sees something on the battlefield in another area, the BC can change his gunner's sight picture instantly.
The A3's on-board diagnostics capability will enable it to execute a system-level built-in test on power up and continually monitors system status while power is applied. Malfunctions are to be displayed on the commander's tactical display to alert the crew of potentially dangerous faults. Pre-mission and preventive maintenance checks and services are built into software to make it easier for the operator to maintain the system. In the event of a failure which the crew cannot correct, maintenance personnel will no longer have to lug around six boxes of test equipment and a series of more than 13 technical manuals in order to troubleshoot the vehicle. The vehicle diagnostic and maintenance software will provide embedded diagnostic and maintenance capability.
Improvements to the sights will be combined with the advent of the squad leader's display, voice and data radios, digital maps, alerts, malfunctions, and digital messaging. Other improvements include a larger gas particulate filter system, along with additional crew stations and heaters, to provide NBC protection for the entire crew, both mounted and dismounted.
Approximately 1,602 Bradley A2s will be remanufactured into A3s, including fire support and air defense derivatives. Engineering and manufacturing development of the A3 upgrade will continue through FY 1999. In March 1994, the Army awarded a contract to United Defense, Limited Partnership, to begin the engineering and manufacturing development phase. In June 1997, the Army approved the first LRIP for 35 systems with an FY98 option for an additional 18 systems, and low-rate production began in July 1997. A subsequent LRIP decision is scheduled for FY99 for 78 systems. The IOT&E for the BFVS-A3 is scheduled for 3/4QFY99. This IOT&E will be conducted in conjunction with the FOT&E 3 for the M1A2 Abrams System Enhancement Program. The LFT&E is scheduled for 3QFY98 through 1QFY99. The full rate production milestone decision is scheduled for 1QFY00.
The hull of the Bradley is constructed of welded aluminum and supplemented at critical locations by spaced laminate armor. The latest version of the Bradley, the M2A2, has additional applique steel armor to help defeat ballistic ammunition, with provision for explosive reactive armor for increased protection against shaped charge weapons. The Applique armor tile system is designed to increase the survivability of the Bradley Fighting Vehicle System (BFVS) against shaped-charge threats using reactive armor technology. Information regarding the specific mechanism of operation and threat level is classified SECRET. A Bradley vehicle set of armor tiles consists of 105 tiles in the following quantities: 26 M3A1, 9 M4A1, 55 M5A,1 7 M6A1, and 8 M7A1. The armor tiles were subjected to comprehensive technical testing and evaluation during Phase II (screening tests) and Phase III (performance specification qualification tests). The coordinated test plan for this evaluation was formulated by AMSAA, TECOM, CSTA, PM - Bradley, and ARDEC. The testing has demonstrated the tiles are safe and meet the performance requirements.
