is developing further upgrades proposed for the Continuous Electronics Enhancement Program (CEEP)building on the latest System Enhancement Package (SEP) and Tank Urban Survivability Kit (TUSK) configurations of M1A1 and M1A2 main battle tanks.
CEEP incorporates advanced digital systems improving the warfighting capability of the crew, and ensuring compatibility with the standards to be implemented by the Army’s future combat systems. CEEP will be introduced as a retrofit into current SEP models. The upgrades will include advanced displays showing color maps, sensor imagery and situational pictures. The systems will support wireless technologies to enable remote diagnostics, vehicle monitoring and dismounted command and control. Individual displays will be introduced to all crew members, improving intra-vehicular connectivity. The tank will be equipped with a new battery system, extending the silent watch capability and eliminating the need for an auxiliary power unit.
The M1A2 System Enhancement Package (SEP V1) was introduced as part of a continuous upgrade path for M1A2 tanks. The kit introduced an armor enhancement in the form of a monolithic and composite armor, and compartmented storage for fuel and ammunition. The turbine engine was improved, to become true multi-fuel system. It uses digital control for optimal operation. The Auxiliary Power Unit (APU) was moved under armor, protecting the tank’s power supply when at static positions.
The tank is fitted with second generation thermal imaging systems for the commander’s independent viewer (CITV) and gunner. The sight uses 2nd generation FLIR and is fully stabilized, enabling fire on the move capability in day or night. The driver has a wide-field-of-view thermal driver vision enhancer (DVE) for driving and situational awareness. Vetronics systems include enhanced GPS and inertial position/navigation system, driving a color, digital terrain map display. The tank also received an eyesafe laser rangefinder. Radios include SINCGARS and Enhanced Position/Location Reporting System (EPLRS) supporting tactical situational picture via the FBCB2 system. Systems on board are integrated via digital databus architecture. To improve maintenance, the tank is equipped with on-board malfunction detection system. Other elements in the SEP V1 program includes Pulse Jet Air System (PJS) enabling self-cleaning of the engine air filters, thermal management system In November and December 2006 The U.S. Army Tank-Automotive and Armaments Command awarded GDLS several contracts worth over US$800 million for M1A2SEP reset work, starting 2007 through 2009.
TheImproved SEP (SEP V2) Reset program applies lessons learned from recent M1A2 SEP reset efforts and aims to bolster the reliability and durability of tanks emerging from the reset process. SEP V2 includes improved displays, sights, power, and a tank-infantry phone. It represents the most technologically advanced tank and can accommodate future technology improvements to ensure compatibility with the Army’s Future Combat Systems.
The First SEP V2 contract included $27 million of funding for the reset and upgrade of 72 M1A2 SEP Abrams tanks to be processed at General Dynamics employees in Anniston, Ala.; Tallahassee, Fla.; Lima, Ohio; Sterling Heights, Mich.; and Scranton, Pa. between February and October 2007. Additional $278 million are set for long-lead material procurement for the reset and upgrade of additional 240 tanks in 2008-2009. The program was initiated with a $46 million long-lead material award in July 2006 for the first 72 tanks. In November 2007 the Army awarded additional $89 for additional upgrades. The second award covered work on 240 tanks to be completed by 2009.
In February 2008was awarded a first order, under a new multi-year upgrade modernization of 435 M1A1 Abrams main battle tanks into M1A2 Systems Enhancement Package (SEP) Version Two (V2) configuration. The first increment of this multi-year contract is valued at $39 million, funding upgrades for 20 M1A1 Abrams tanks. An earlier $12.4 award announced in January million funded parts for this upgrade. The newly awarded contract will complete the modernization of all remaining M1A1 tanks, expected to maintain the backbone of the U.S. Army’s heavy force in the next decades.
